Defining Deterrence

1 Introduction The search of one’s home, person or vehicle with or without a warrant may, depending on the circumstances, constitute a violation of the right to privacy. Our courts determine whether state action (police conduct) constitutes a violation of a complainant’s right to privacy or any other right by applying two tests. First, the courts must determine the scope of the right to privacy and consider whether the police conduct breached the complainant’s right to privacy; if not, that would be the end of the matter. However, if the police conduct did breach the complainant’s right to privacy, the courts would continue with the second test. The second test determines whether the police conduct is justified because they, for example, acted in terms of the provisions of the Criminal Procedure Act 51 of 1977 (as amended). This second test is referred to as the limitations analysis under s 36 of the Constitution. If the police conduct cannot be justified in terms of s 36 because the police officer, for example, exceeded the powers granted to him or her in terms of the Criminal Procedure Act, the complainant would have succeeded in establishing that his or her right to privacy has been violated. (Section 36 is included in the appendices at the end of this book.) Search, seizure, and matters related thereto are regulated by Chapter 2 (s 19 and sections that follow) of the Criminal Procedure Act. The Criminal Procedure Act embodies the general provisions with regard to searching; specific provisions are contained in many other acts. It is impossible to refer to all these acts. Section 19 of the Criminal Procedure Act states explicitly that Chapter 2 of the Act shall not derogate from any power conferred by any other Act to enter any premises or to search any person, container or premises or to seize any matter, to declare any matter forfeited or to dispose of any matter. 2 The scope and content of the right to privacy The right to privacy seeks to protect the right not to have one’s person or home searched, one’s property searched, one’s possessions seized, or the privacy of one’s communications infringed. The scope of the right to privacy is determined by the concept of a ‘legitimate expectation of privacy’ (Bernstein v Bester 1996 (2) SA 751 (CC) at [75]). Our courts do not define the right to privacy; instead, they apply the notion of a ‘spectrum’ of privacy protection, consisting of a small circle, followed by a number of bigger circles surrounding the central circle. The small central circle represents the intimate core of privacy, relating to, for example, what one does in one’s bedroom, and wider circles beyond this central core represent social interactions of a less private nature such as, for example, travelling in public transport. Interferences with the central core may only be justified in exceptional circumstances, whereas interferences with the outer circles, which are far removed from the centre of privacy, are less demanding to defend (Minister of Police v Kunjana 2016 (2) SACR 473 (CC) [2016] ZACC 21 at [17]). In other words, the more a search and seizure interferes with the central core of privacy, the more challenging it will be to justify such interference. Privacy is also intrinsically linked to human dignity, which constitutes one of the most significant values our constitution seeks to uphold (Investigating Directorate: Serious Economic Offences v Hyundai Motor Distributors Page 192 (Pty) Ltd 2001 (1) SA 545 (CC) at [18]; Thint (Pty) Ltd v National Director of Public Prosecutions 2008 (2) SACR 421 (CC) [2008] ZACC 13 at [77]). 3 Articles that are susceptible to seizure The Criminal Procedure Act confers powers to search only where the object of the search is to find a certain person or to seize an article which falls into one of three classes of articles, including documents, which may be seized by the state in terms of the provisions of the Criminal Procedure Act. These are— (1) articles which are concerned in or are on reasonable grounds believed to be concerned in the commission or suspected commission of an offence, whether within the Republic or elsewhere—s 20(a); (2) articles which may afford evidence of the commission or suspected commission of an offence, whether within the Republic or elsewhere—s 20(b); or (3) articles which are intended to be used or are on reasonable grounds believed to be intended to be used in the commission of an offence—s 20(c). Under normal circumstances an article or document falling into one of the abovementioned categories may be seized by the state. The only exceptions relate to documents which are privileged and in respect of which the holder of the privilege has not yet relinquished his or her privilege. An example of this would be where the document consists of a communication between an attorney and his or her client. Such a document is subject to legal professional privilege and may not be handed in to the court without the consent of the client. If the state had the power to seize such a document the whole object of the privilege would be defeated. In Prinsloo v Newman 1975 (1) SA 481 (A) at 493F–G and SASOL III (Edms) Bpk v Minister van Wet en Orde 1991 (3) SA 766 (T) it was accordingly held that such a document may not be seized. 4 Search in terms of a search warrant 4.1 General rule Searches and seizures should, whenever possible, be conducted only in terms of a search warrant, issued by a judicial officer such as a magistrate or judge—cf the wording of s 21(1). This will ensure that an independent judicial officer stands between the citizen and the law enforcement official (police official)—Park-Ross v Director: Office for Serious Economic Offences 1995 (2) SA 148 (C) at 172. For this reason the provisions governing the issue of search warrants require that the judicial officer must himself or herself decide whether or not there are ‘reasonable grounds’ for the search. 4.2 The discretion of a judicial officer to issue a warrant In deciding whether there are reasonable grounds for the search, the judicial officer exercises a discretion similar to the discretion he or she exercises in granting bail, remanding a case or sentencing an accused, and so forth. This discretion must be exercised in a judicial manner. This simply means that the judicial officer must exercise the discretion in a reasonable and regular manner, in accordance Page 193 with the law and while taking all relevant facts into account—Minister of Safety and Security v Van der Merwe 2011 (5) SA 61 (CC). Before issuing a search warrant the judicial officer must therefore decide whether the article that will be searched for is one which may be seized in terms of s 20 and whether it appears from the affidavit that there are reasonable grounds to believe that the article is present at a particular place (Minister of Safety and Security v Van der Merwe, above). As far as the concept of ‘reasonable grounds’ is concerned, see the discussion of the requirement of reasonableness in Chapter 6. Government action is required to be objectively and demonstrably reasonable. This laudable principle was unfortunately undermined by the decision in Divisional Commissioner of SA Police, Witwatersrand Area v SA Associated Newspapers 1966 (2) SA 503 (A), where it was held that the merits of the decision by a justice of the peace, that there are objective grounds upon which a warrant may be issued, may not be contested in court (contrary to where a search without a warrant is conducted by the police). The decision to issue a search warrant may, in terms of this decision, be set aside only on administrative grounds (such as mala fides on the part of the judicial officer) and not on the merits. This decision was quoted with approval in Cresto Machines v Die Afdeling-Speuroffisier SA Polisie, Noord-Transvaal 1972 (1) SA 376 (A) 396; cf further Cine Films (Pty) Ltd v Commissioner of Police 1971 (4) SA 574 (W) 581. Mogoeng CJ, in Minister of Safety and Security v Van der Merwe 2011 (5) SA 61 (CC), held (at [55]) that a judicial officer must ensure that the following prerequisites are complied with before authorising a warrant: (a) the warrant must mention the statutory provision in terms of which it is authorised; (b) it must identify the searcher; (c) it must clearly describe the scope of the powers granted to the searcher; (d) it must identify the person, container or premises to be searched; (e) it must clearly describe the article to be searched for and seized; (f) it must mention the offence being investigated; (g) it must state the name of the person being investigated. 4.3 General search warrants The procedure with regard to search warrants is governed by s 21. Subsection (1) provides that, subject to ss 22, 24 and 25 (see below), an article referred to in s 20 shall be seized only by virtue of a search warrant issued— (a) by a magistrate or justice, if it appears to such magistrate or justice from information on oath that there are reasonable grounds for believing that any such article is in the possession or under the control of any person, or upon or at any premises within his area of jurisdiction; or (b) by a judge or judicial officer presiding at criminal proceedings, if it appears to such judge or judicial officer that any such article in the possession or under the control of any person or upon or at any premises is required in evidence at such proceedings. Page 194 Section 21(2) stipulates that a warrant must direct a police official to seize the article in question and must to that end authorise such police official to search any person identified in the warrant, or to enter and search any premises identified in the warrant and to search any person found on or at such premises. See also Extra Dimension v Kruger NO 2004 (2) SACR 493 (T). In Minister of Safety and Security v Van der Merwe 2011 (5) SA 61 (CC) at [56] Mogoeng CJ set out the following guidelines that our courts must take into account when assessing the validity of search and seizure warrants. These are whether— (a) the person who authorised a warrant has authority to do so; (b) the person (mentioned in (a)) has jurisdiction to authorise a warrant; (c) the affidavit contains information regarding the existence of the jurisdictional facts (meaning a reasonable suspicion that a crime has been committed and reasonable grounds to believe that objects connected to crime may be found on the premises); (d) the scope (boundaries) of the search that must be conducted are clear and not overbroad or vague; (e) the searched person’s constitutional rights are not unnecessarily interfered with. Mogoeng CJ also mentioned that the terms of a warrant must be strictly interpreted, in order to protect the searched person against excessive interference by the state (Van der Merwe above at [56]; also Thint (Pty) Ltd v National Director of Public Prosecutions; Zuma v National Director of Public Prosecutions 2008 (2) SACR 421 (CC)). The decision in Goqwana v Minister of Safety and Security 2016 (1) SACR 384 (SCA) explained the importance of the prerequisites and guidelines mentioned in the Van der Merwe case above, by highlighting three important points: first, the reason why the identity of the searcher must be mentioned in a warrant is to ensure accountability in case the searcher abuses his or her power (at [25]; secondly, where the search is in connection with a statutory offence, as opposed to a common-law offence, the relevant statute and section must be mentioned, in order to enable both the searcher and the searched person to know exactly what the warrant has been authorised for (at [29]); and thirdly, the affidavit in support of the warrant should accompany the warrant and should be handed to the searched person in case he or she wants to challenge the validity of the warrant (at [31]). Even though s 21 does not require that the suspected offence be set out in the warrant, it is desirable to do so in order to facilitate the interpretation of the warrant— Minister of Safety and Security v Van der Merwe above at [56]. The powers conferred by s 21 constitute grave infringements of the privacy of the individual. To limit this infringement, s 21(3)(a) provides that a search warrant must be executed (ie acted upon) by day, unless the judicial officer who issues it gives written authorisation for it to be executed by night. A warrant may be issued and be executed on a Sunday, as on any other day, and remains in force until it is executed or is cancelled by the person who issued it or, if such person is not available, by a person with like authority—s 21(3)(b). Page 195 4.4 Warrants to maintain internal security and law and order 4.4.1 Background In Wolpe v Officer Commanding South African Police, Johannesburg 1955 (2) SA 87 (W) members of the police entered a hall in which a conference was being held by the ‘South African Congress of Democrats’ in co-operation with other organisations. The chairman requested the police to leave the meeting and explained that it was a private meeting. The police refused to do so. Members of the Congress of Democrats thereupon brought an urgent application to the court for an interdict prohibiting the police from attending the meeting. They argued that the police do not have greater powers than any other individual, except in so far as they are vested with wider powers by statute. The application was refused. Rumpff J held that the basic duties of the police are not confined to those mentioned in statutes. The basic duties of the police flow from the nature of the police as a civil force in the state. According to him it was not the intention of the legislature by s 7 of the (previous) Police Act to revoke the basic duties of the police and to supplant them with statutory duties. The judge dealt fully with the duties of the police and came to the conclusion that if there were a suspicion that as a result of the holding of a meeting, a disturbance of public order would occur on the same day, the police are entitled to attend the meeting in order to prevent a disturbance of order, even though the meeting was private. If the police had reasonable grounds for suspecting that seditious speeches would be made at such meeting, and that their presence would prevent them from being made, it would be a reasonable exercise of their duty for the police to attend the meeting, notwithstanding the fact that there would be no immediate disturbance of the peace. According to Rumpff J the liberty of the individual must in such circumstances give way to the interests of the state. He suggested, however, that the legislature should define the duties and powers of the police in connection with the combating of what the state from time to time considered to be dangerous. This eventually led to the inclusion of s 25 in the current Criminal Procedure Act. 4.4.2 Warrant in terms of s 25 Section 25(1) stipulates that if it appears to a magistrate or justice from information on oath that there are reasonable grounds for believing— (a) that the internal security of the Republic or the maintenance of law and order is likely to be endangered by or in consequence of any meeting which is being held or is to be held in or upon any premises within his area of jurisdiction; or (b) that an offence has been or is being or is likely to be committed or that preparations or arrangements for the commission of any offence are being or are likely to be made in or upon any premises within his area of jurisdiction, he may issue a warrant authorising a police official to enter the premises in question at any reasonable time for the purpose— (i) of carrying out such investigations and of taking such steps as such police official may consider necessary for the preservation of the internal security of Page 196 the Republic or for the maintenance of law and order or for the prevention of any offence; (ii) of searching the premises or any person in or upon the premises for any article referred to in s 20 and which such police official on reasonable grounds suspects to be in or upon or at the premises or upon such person; and (iii) of seizing any such article. A warrant under sub-s (1) may be issued on any day and shall remain in force until it is executed or is cancelled by the person who issued it or, if such person is not available, by a person with like authority—sub-s (2). A warrant issued in terms of s 25(1)(i) confers wide powers on the police. The fact that a police official who acts in terms thereof may take any steps that he or she ‘may consider necessary’ for the preservation of the internal security of the Republic or for the maintenance of law and order or for the prevention of any offence means that the police official’s discretion in this respect will have to be considered subjectively. The question will therefore not be whether the steps the police officer took were really necessary, but whether such officer subjectively thought that he or she had reason to believe that they were necessary. Moreover, this provision sets no legal boundaries within which such discretion powers may be exercised, thus leaving ample room for the abuse of power (see Minister of Police and Others v Kunjana 2016 (2) SACR 473 (CC)). 4.5 General information requirements with regard to warrants When law enforcement officials act in terms of a warrant, it is desirable that the subject involved has access to the document which authorises an infringement upon his or her private rights. The effective execution of legal remedies, such as an interdict, mandament van spolie, or even the institution of the rei vindicatio, is to a large extent dependent on this (see Tsegeya v Minister of Police (unreported, Mthatha High Court case no 2746/2018 21 August 2018). Section 21(4) therefore stipulates that a police official who executes a warrant in terms of ss 21 or 25 must, once the warrant has been executed and upon the request of any person whose rights are affected by the search or seizure of an object in terms of the warrant, provide such a person with a copy of the warrant (see Goqwana v Minister of Safety and Security, above, which goes even further by requiring that the supporting affidavit to the warrant be handed to the person whose property forms the subject of the search). We are of the opinion that two objections may be raised against this subsection, which is laudable in other respects. In the first place a copy of the warrant should, whenever possible (ie if the subject is present at the time of the execution of the warrant), be provided before the search and/or seizure. Secondly, the delivery of a copy of the warrant should not be dependent on the request of the subject. Many subjects, through lack of knowledge of the law, will not make such a request and thus act to their potential detriment. Page 197 5 Search without a warrant 5.1 Introduction Although it is preferable, as mentioned above, that searches should only be conducted on the authority of a search warrant issued by a judicial officer, it is quite conceivable that circumstances may arise where the delay in obtaining such warrant would defeat the object of the search. It is therefore necessary that provision be made for the power to conduct a search without a warrant. However, police officials intending to conduct a search and seizure should always be conscious of the cautionary remark made by Madlala J in Minister of Police v Kunjana 2016 (2) SACR 473 (CC) at [27]: It should not be forgotten that exceptions to the warrant requirement should not become the rule. While search warrants empower only police officials to conduct searches and to seize objects, both private persons and police officials are empowered to conduct searches or to seize objects without a warrant. 5.2 Powers of the police 5.2.1 Consent to search and/or to seize In terms of s 22(a) a police official may search any person, container or premises for the purpose of seizing any article referred to in s 20, if the person concerned consents to the search for and the seizure of the article in question, or if the person who may consent to the search of the container or premises consents to such search and the seizure of the article in question. 5.2.2 Search and seizure where a delay would defeat the object thereof In terms of s 22(a) a police official may search any person, container or premises for the purpose of seizing any article referred to in s 20, if the police official believes on reasonable grounds that— (1) a search warrant will be issued to him or her under s 21(1)(a) if he or she applies for such warrant; and (2) the delay in obtaining such warrant would defeat the object of the search. The belief of the police official must be objectively justified on the facts—NDPP v Starplex 47 CC [2008] 4 All SA 275 (C). Section 25(3) allows a police official to act without a warrant if he or she believes on reasonable grounds that— (1) a warrant will be issued to him or her under s 25(1)(a) or (b) if he applies for such warrant; and (2) the delay in obtaining such warrant would defeat the object thereof. A police official’s powers in terms of s 25(3) are the same as the powers he or she would have had by virtue of a warrant (cf (i) to (iii) above and NDPP v Starplex 47 CC above. In Starplex a search warrant was issued to search certain premises under s 33(5) of the Immigration Act, on the grounds that information had been received that a group of foreign nationals issued false documents and permits. During the search a significant amount of foreign currency was discovered and Page 198 consequently seized. The seizure of the money was challenged on the ground that the search warrant did not authorise its seizure. The court rejected this contention on the basis that suspects could quickly hide away the money from the authorities in order to prevent its seizure, and the money was reasonably suspected as being illegal foreign currency. Expecting the police to obtain a new warrant under those circumstances would defeat the object of the search. In the result, the court held that the money was lawfully seized in terms of s 22(2).) 5.2.3 Search and seizure for the purposes of border control Section 13(6) of the South African Police Service Act 68 of 1995 empowers a police official, for the purposes of border control or to control the import or export of any goods, to search without a warrant any person, premises, other place, vehicle, vessel, ship, aircraft or any receptacle of whatever nature, at any place in the Republic within ten kilometres or any reasonable distance from any border between the Republic and any foreign state, or from any airport or at any place in the territorial waters of the Republic or inside the Republic within ten kilometres from such territorial waters, and to seize anything found upon such person or upon or at or in such premises, other place, vehicle, vessel, ship, aircraft or receptacle which may lawfully be seized. 5.2.4 Search and seizure in a cordoned-off area The National or a Provincial Commissioner of the South African Police Service may, in terms of s 13(7) of the South African Police Service Act 68 of 1995, where it is reasonable in the circumstances in order to restore public order or to ensure the safety of the public in a particular area, authorise that the particular area or any part thereof be cordoned off. This is done by issuing a written authorisation which must also set out the purpose of the cordoning off. Any member of the Service may, in order to achieve the purpose set out in the authorisation, without a warrant, search any person, premises, vehicle or any receptacle or object of whatever nature in that area and seize any article referred to in s 20 of the Criminal Procedure Act found by him or her upon such person or in that area: provided that a member executing a search in terms of s 13(7) must, upon demand of any person whose rights are or have been affected by the search or seizure, exhibit to him or her a copy of the written authorisation by such commissioner. 5.2.5 Search and seizure at a roadblock or checkpoint The National or a Provincial Commissioner of the South African Police Service may, in terms of s 13(8) of the South African Police Service Act 68 of 1995, where it is reasonable in the circumstances in order to exercise a power or perform a function of the Service, in writing authorise a member under his or her command to set up a roadblock or roadblocks on any public road in a particular area or to set up a checkpoint or checkpoints at any public place in a particular area. Any member of the Service may, without a warrant, search any vehicle and any person in or on such vehicle at such a roadblock or checkpoint and seize any article referred to in s 20 of the Criminal Procedure Act found by him or her upon such person or in or on such vehicle. A member executing a search in terms of s 13(8) Page 199 must, upon demand by any person whose rights are or have been affected by the search or seizure, exhibit to him or her a copy of the written authorisation by such commissioner. Section 13(8)(d) authorises any member of the Service to set up a roadblock on a public road without a written authorisation in certain specified circumstances where the delay in obtaining a written authorisation would defeat the object of the setting up of the roadblock. 5.2.6 Search and seizure in terms of the Drugs and Drug Trafficking Act 140 of 1992 Search for and seizure of substances in terms of the Drug and Drug Trafficking Act was, until recently, controlled by s 11 of the Act. Prior to the declaration of constitutional invalidity in Minister of Police v Kunjana 2016 (2) SACR 473 (CC), s 11(1) of the Act read as follows: (1) A police official may— (a) if he has reasonable grounds to suspect that an offence under this Act has been or is about to be committed by means or in respect of any scheduled substance, drug or property, at any time— (i) enter or board and search any premises, vehicle, vessel or aircraft on or in which any such substance, drug or property is suspected to be found; (ii) search any container or other thing in which any such substance, drug or property is suspected to be found; (b) if he has reasonable grounds to suspect that any person has committed or is about to commit an offence under this Act by means or in respect of any scheduled substance, drug or property, search or cause to be searched any such person or anything in his possession or custody or under his control: Provided that a woman shall be searched by a woman only; (c) if he has reasonable grounds to suspect that any article which has been or is being transmitted through the post contains any scheduled substance, drug or property by means or in respect of which an offence under this Act has been committed, notwithstanding anything to the contrary in any law contained, intercept or cause to be intercepted either during transit or otherwise any such article, and open and examine it in the presence of any suitable person; (d) question any person who in his opinion may be capable of furnishing any information as to any offence or alleged offence under this Act; (e) subject to s 15 of the Regulation of Interception of Communications and Provision of Communication-related Information Act, 2002, require from any person who has in his or her possession or custody or under his or her control any register, record or other document which in the opinion of the police official may have a bearing on any offence or alleged offence under this Act, to deliver to him or her then and there, or to submit to him or her at such time and place as may be determined by the police official, any such register, record or document; (f) examine any such register, record or document or make an extract therefrom or a copy thereof, and require from any person an explanation of an entry in any such register, record or document; (g) seize anything which in his opinion is connected with, or may provide proof of, a contravention of a provision of this Act. The constitutional validity of the entire s 11 was challenged by the applicant in Kunjana v Minister of Police [2015] ZAWCHC 198 (High Court judgment). On consideration the High Court, per Veldhuizen J, concluded that the application directed at the entire s 11 was too broad and restricted the relief to s 11(1)(a) and (g). The High Court declared the provisions invalid and the matter was placed before Page 200 the Constitutional Court for confirmation of the order of invalidity (Minister of Police v Kunjana 2016 (2) SACR 473 (CC). The Constitutional Court applied the limitation clause to s 11(1)(a) and (g). On consideration of the nature and extent of the limitation the court remarked: The impugned provisions are broad. Section 11(1)(a) and (g) of the Drugs Act does not circumscribe the time, place nor manner in which the searches and seizures can be conducted. . . (at [21]). Further, section 11(1)(a) grants police officers the power to search warrantless at ‘any time’ ‘any premises, vehicle, vessel or aircraft’ and ‘any container’ in which substances or drugs are suspected to be found (at [22]). I agree with the applicants’ contention that the impugned provisions leave police officials without sufficient guidelines with which to conduct the inspection within legal limits (at [23]). The court next considered whether there are less restrictive means to achieve the purpose of s 11(1)(a) and (g) and reasoned that— [s]ection 11(1)(a) implies that warrantless searches of private homes may be conducted pursuant to it. The more a search intrudes into the ‘inner sanctum’ of a person (such as their home) the more the search infringes their privacy right. The provisions are also problematic as they do not preclude the possibility of a greater limitation of the right to privacy than is necessitated by the circumstances, with the result that police officials may intrude in instances where an individual’s reasonable expectation of privacy is at its apex. The court contended that constitutionally adequate safeguards must exist to justify circumstances in which legislation allows for warrantless searches. These safeguards are clearly provided by s 22 of the Criminal Procedure Act, which provides less restrictive means to restrict the right to privacy during search and seizure procedures. The Constitutional Court accordingly confirmed the constitutional invalidity of ss 11(1)(a) and (g). Warrantless search and seizure should not be a norm of criminal procedure, which is confirmed by the various court interventions in, for example, the Customs and Excise Act 91 of 1964, Estate Agency Affairs Act 112 of 1976 and Financial Intelligence Centre Act 38 of 2001, wherein the validity of warrantless search and seizure provisions were challenged (see also Estate Agency Affairs Board v Auction Alliance (Pty) Ltd 2014 (3) SA 106 (CC) and Gaertner v Minister of Finance 2014 (1) SA 442 (CC)). Search and seizure under the provisions of a warrant should form the basis of any such action because— [a] warrant is not a mere formality. It is a mechanism employed to balance an individual’s right to privacy with the public interest in compliance with and enforcement of regulatory provisions. A warrant guarantees that the State must be able, prior to an intrusion, to justify and support intrusions upon individuals’ privacy under oath before a judicial officer. Further, it governs the time, place and scope of the search. This softens the intrusion on the right to privacy, guides the conduct of the inspection, and informs the individual of the legality and limits of the search. Our history provides evidence of the need to adhere strictly to the warrant requirement unless there are clear and justifiable reasons for deviation (Gaertner at [69]). The above notwithstanding, there are instances where warrantless search and seizure is clearly indicated, but they must be conducted under the prescriptions of s 22 of the Criminal Procedure Act where there is a need for swift action. Page 201 5.3 Powers of the occupiers of premises In terms of s 24 of the Criminal Procedure Act any person who is lawfully in charge or occupation of any premises and who reasonably suspects that— (1) stolen stock or produce, as defined in any law relating to the theft of stock or produce, is on or in the premises concerned, or that (2) any article has been placed thereon or therein or is in the custody or possession of any person upon or in such premises in contravention of any law relating to— (a) intoxicating liquor, (b) dependence-producing drugs, (c) arms and ammunition, or (d) explosives, may at any time, if a police official is not readily available, enter such premises for the purpose of searching such premises and any person thereon or therein, and if any such stock, produce or article is found, he shall take possession thereof and forthwith deliver it to a police official. 5.4 Search for the purpose of effecting an arrest In the event of a search of premises in order to find and arrest a suspect, exactly the same powers are conferred on police officials and private persons. In terms of s 48, a peace officer or private person who is authorised by law to arrest another in respect of any offence and who knows or reasonably suspects such other person to be on any premises may, if he or she first audibly demands entry into such premises and states the purpose for which he or she seeks entry and fails to gain entry, break open and enter and search such premises for the purpose of effecting the arrest. A number of court decisions on the forerunner of s 48 still apply to s 48. These include the following: In Jackelson 1926 TPD 685 it was held that persons who had ejected a police official who had entered premises without first demanding and being refused admission could not be convicted of obstructing such police official in the execution of his duty. In Rudolf 1950 (2) SA 522 (C) a police official had seen a man drinking wine in a public place and wished to arrest him. The man ran into a house pursued by the constable and was arrested at the foot of the stairs. The two accused attempted to rescue the wine-drinker from the custody of the police official. It was contended, inter alia, that the wine-drinker had not been in ‘lawful custody’ because the police official had made an unlawful entry when he entered the premises without first demanding admission in terms of the predecessor to the present s 48. The court held, however, that the constable had been justified, in the circumstances of the case, in entering the house to arrest the wine-drinker and consequently the arrest was a lawful one. The court distinguished Jackelson mainly on the ground that the accused in Jackelson had ejected the constable before he had effected an arrest, while in Rudolf the arrest had been effected when the accused attempted to rescue the wine-drinker— cf also Andresen v Minister of Justice 1954 (2) SA 473 (W). Page 202 5.5 Review of the actions of the person conducting the search In cases where action is taken without a warrant, the actions of the person conducting the search may be reviewed by a court of law on the merits—cf eg LSD Ltd v Vachell 1918 WLD 127. 6 Search of an arrested person This matter is governed by s 23. That section provides that on the arrest of any person, the person making the arrest may, provided that he or she is a peace officer, search the person arrested and seize any article referred to in s 20 which is in the possession or under the control of the arrested person. If the person making the arrest is not a peace officer, he or she has no power to search the arrested person. The person making the arrest does, however, have the power to seize an article referred to in s 20 which is in the possession or under the control of the arrested person. Such a private person must forthwith hand the seized article to a police official. (This also applies to a peace officer who is not a police official). On the arrest of any person, the person effecting the arrest may place in safe custody any object found on the arrested person which may be used to cause bodily harm to himself or herself or to others—s 23(2). 7 The use of force in order to conduct a search The use of force is regulated by s 27 as far as this chapter is concerned. In terms of s 27(1), a police official who may lawfully search any person or any premises may use such force as may be reasonably necessary to overcome any resistance against such search or against entry of the premises, including the breaking of any door or window of such premises. In terms of a proviso to this subsection, such a police official shall first audibly demand admission to the premises and state the purpose for which he or she seeks to enter such premises. This proviso does not apply where the police official concerned is, on reasonable grounds, of the opinion that any article which is the subject of the search may be destroyed or disposed of if the proviso is first complied with—s 27(2). The latter is known as the ‘no-knock clause’ and is particularly helpful to the police where the search will be for small objects which may easily be swallowed or flushed down a toilet. 8 General requirement of propriety with regard to searching Section 29 stipulates that a search of any person or premises shall be conducted with strict regard to decency and order, and a woman shall be searched by a woman only, and if no female police official is available, the search shall be made by any woman designated for the purpose by a police official. In order to comply with the requirement of propriety in terms of s 29, it can certainly be assumed, in terms of the general principles of the interpretation of statutes, that a male person should be searched by a male only. We suggest that any divergence from these provisions would be unlawful and that ‘consent’ by Page 203 the person being searched by the opposite sex would be invalid as it would be contra bonos mores. 9 Unlawful search The provisions of the law of criminal procedure which regulate searching are ‘double- functional’: From a substantive law viewpoint they constitute grounds of justification, while in formal law they regulate the procedural steps whereby an eventual legal decision may validly be reached. In the latter case the principle of legality (cf Chapter 1) and the concept of ‘legal guilt’ are of paramount importance in that, unless a ‘factually guilty’ person can be brought to justice within the bounds of the provisions of the law of criminal procedure (ie in strict compliance with the prescribed rules and limitations), he or she must, according to law, go free—see Chapter 1. The question now arises as to what the effect is of unlawful action by the authorities with regard to these pre-trial procedural rules. As these provisions are double- functional, it is necessary to differentiate between the substantive and formal law consequences: 9.1 Formal-law consequences of unlawful action by the authorities In terms of s 35(5) of the Constitution, evidence obtained in a manner that violates any right in the Bill of Rights must be excluded if the admission of that evidence would render the trial unfair or otherwise be detrimental to the administration of justice. This so-called ‘exclusionary rule’ gives a clear signal to all state officials that it is futile to gather evidence in an unlawful manner, since evidence so obtained will not be taken into account by the court in reaching a verdict. (See Motloutsi 1996 (1) SA 584 (C) and Mayekiso 1996 (2) SACR 298 (C).) Evidence obtained in terms of an invalid search warrant may be excluded under s 35(5) of the Constitution. Heaney 2016 JDR 0806 (GP) is an appeal where the accused, in his capacity as a member of a close corporation, challenged the validity of a search warrant. This challenge was based on the grounds that the affidavit in support of the authorisation of the warrant was unsigned and not commissioned; it authorised the station commander (and not a specific police officer) to conduct the search (without mentioning a police station); and the offence and article which had to be seized was not clearly identified. On appeal, the court declared the warrant invalid. The court held that the execution of this invalid warrant violated the right to privacy of the accused. The right to privacy is a right guaranteed under s 14 of the Constitution and the evidence was accordingly obtained in a manner that violated a right guaranteed in the Bill of Rights. This, the court held, triggered s 35(5) of the Constitution, calling upon a court to determine whether the admission of the evidence obtained in this manner would render the trial unfair or otherwise be detrimental to the administration of justice. In the result, the evidence seized was excluded under s 35(5) and the appeal was upheld (see also Oforah 2013 JDR 1956 (GSJ). The admissibility of evidence under s 35(5) must, in general, be determined during a trial within a trial (Tandwa 2008 (1) SACR 613 (SCA). Page 204 The exclusionary rule is discussed in more detail in handbooks dealing with the law of evidence and was briefly dealt with in Chapter 1. 9.2 Substantive-law consequences of unlawful action by the authorities This aspect is governed partly by s 28. In terms of sub-s (1), a police official commits an offence and is liable on conviction to a fine or to imprisonment for a period not exceeding six months— (1) when he acts contrary to the authority of a search warrant issued under s 21 or a warrant issued under s 25(1); or (2) when he, without being authorised thereto, (a) searches any person or container or premises or seizes or detains any article; or (b) performs any act contemplated in s 25(1). Subsection (2) stipulates that where any person falsely gives information on oath for the purposes of ss 21(1) or 25(1) and a warrant is issued and executed on such information, and such person is in consequence of such false information convicted of perjury, the court convicting such person may, upon the application of any person who has suffered any damage in consequence of the unlawful entry, search or seizure, or upon the application of the prosecutor acting on the instructions of such a person, award compensation in respect of such damage, whereupon the provisions of s 300 shall mutatis mutando of ownership. The object is therefore no longer regarded as stolen property and may then be restored to the person from whom it was forfeited, if he or she bought it from another. The former person is then considered as ‘the person who may lawfully possess it’—Mdunge v Minister of Police 1988 (2) SA 809 (N); Datnis Motors (Midlands) (Pty) Ltd v Minister of Law and Order 1988 (1) SA 503 (N). After the conviction of an accused, the court has, in terms of s 35(1) and in certain circumstances, the power to forfeit to the state certain objects which were used in the commission of the particular crime. Section 36 deals with the circumstances under which, and the manner in which, articles may be delivered to the police of another country. There are also various other laws that make provision for search, seizure and the forfeiture of articles, eg s 29(5) of the National Prosecuting Authority Act 32 of 1998 (cf Thint (Pty) Ltd v National Director of Public Prosecutions; Zuma v National Director of Public Prosecutions 2008 (2) SACR 421 (CC)) and the Prevention of Organised Crime Act 121 of 1998, which provides for confiscation, preservation and forfeiture orders: A confiscation order (s 18) consists therein that a court, convicting an accused of an offence, may, on the application of the public prosecutor, enquire into any benefit which the accused may have derived from that offence (or any other offence of which the accused has been convicted at the same trial or any criminal activity sufficiently related to those offences) and may, in addition to any punishment which it may impose in respect of that offence, make an order against the accused for the payment to the state of any amount it considers appropriate. A preservation order (s 38) prohibits a person from dealing in any manner with any property which is an instrumentality of an offence—ie any property concerned Page 205 in the commission or suspected commission of an offence. Property only qualifies as an instrumentality if it is used to commit the offence and its use must be such that it plays a real and substantial part in the actual commission of the offence. The fact that a crime is committed at a certain place does not by itself make that place an instrumentality of the offence—Singh v National Director of Public Prosecutions 2007 (2) SACR 326 (SCA). A forfeiture order (s 48) is an order forfeiting to the state all or any of the property subject to a preservation of property order and is applied for by the national director of public prosecutions. An order of forfeiture may be made only if the deprivation in a particular case is proportionate to the ends at which the legislation is aimed, and distinctions between different classes of offence will feature heavily in that part of the enquiry. Although an order of forfeiture operates as both a penalty and a deterrent, its primary purpose is remedial. Forfeiture is likely to have its greatest remedial effect where crime has become a business. The Supreme Court of Appeal, accordingly, did not consider a motor vehicle driven whilst under the influence of alcohol ‘an instrumentality of an offence’ as contemplated under the Prevention of Organised Crime Act 121 of 1998—National Director of Public Prosecutions v Vermaak [2008] 1 All SA 448 (SCA). See also Shaik 2008 (1) SACR 1 (CC). Restitution should be distinguished from forfeiture. Restitution is dealt with in Chapter 19

2 Food Deterioration by Chemical Reaction and Physical Damage

Week 5 Absolutely — here’s a condensed study guide that keeps the major concepts (the stuff most likely to be tested), without all the extra detail. Infection Control & Body Defenses — Condensed Study Guide (Major Concepts) Chain of Infection (6 Links + how to break them) 1. Infectious agent (bacteria, viruses, fungi, parasites, prions) ○ Break it: disinfect/sterilize/clean; antimicrobials as ordered 2. Reservoir (where it lives: people/animals/insects; soil, water, food, equipment, IV fluids, feces) ○ Break it: hand hygiene, pre-op skin prep, environmental cleaning 3. Portal of exit (blood/body fluids, respiratory/GI tract, mouth/nose/ears, skin) ○ Break it: contain drainage/secretions (dressings, drains) 4. Mode of transmission ○ Main: contact, droplet, airborne (also vehicle, vector) ○ Break it: hand hygiene + PPE + disinfect shared equipment 5. Portal of entry (orifices, mucous membranes, breaks in skin; invasive devices) ○ Break it: aseptic technique, protect skin, sterile technique when needed 6. Susceptible host (risk depends on immunity/health) ○ Break it: immunizations, nutrition, hygiene, blood sugar control Virulence: how efficient an organism is at making people ill. Modes of Transmission (what to recognize) Contact ● Direct: person-to-person (ex: blood to open abrasion) ● Indirect: contaminated objects/PPE/equipment (ex: bed rails, shared devices) Droplet ● From coughing/sneezing/singing/talking; some procedures (CPR, intubation) ● Examples: influenza, pertussis, RSV, adenovirus, rhinovirus ● Respiratory etiquette + masking when out of room Airborne ● Small particles remain suspended; travel farther ● Requires private room; negative pressure (AIIR) preferred ● Examples: TB, measles (rubeola), varicella Vehicle / Vector ● Vehicle: contaminated food/water (ex: E. coli produce) ● Vector: insects/rodents (mosquitoes, rats) Body Defenses (3 Types) 1. Physical & chemical barriers ○ Skin (primary defense), mucous membranes/mucus, tears/sweat, cilia + cough, stomach acid, normal flora 2. Nonspecific immunity ○ Neutrophils + macrophages (phagocytes “eat and destroy”) 3. Specific immunity ○ Antibodies (immunoglobulins) + lymphocytes Inflammatory Response (key steps + signs) Steps: ● Pattern receptors recognize harmful stimuli ● Inflammatory pathway activated ● Markers released (ex: CRP) ● Inflammatory cells recruited (leukocytes → monocytes/lymphocytes) Signs of inflammation (local tissue): ● heat, redness, swelling, pain, loss of function Triggers can be infectious (viruses/bacteria) or noninfectious (trauma, burns, irritants, toxins, radiation, etc.). Stages of Infection (in order) 1. Incubation (exposure → first symptom; may have lab changes) 2. Prodromal (vague symptoms: malaise, fever, aches) 3. Acute illness (most severe; specific symptoms) 4. Decline (symptoms decrease) 5. Convalescence (recover/return to baseline) Local vs Systemic Infection ● Local: confined to one area (often topical/oral treatment) ● Systemic: enters bloodstream, affects whole body (often IV antibiotics + monitoring) Diagnostic Tests (high-yield) ● UA for UTI symptoms → if WBCs present, culture & sensitivity ● CXR confirms pneumonia/atelectasis but doesn’t tell viral vs bacterial ● CBC + differential ○ Expected WBC: 5,000–10,000/mm³ ○ “Left shift” = increased bands (immature neutrophils) → infection ● Nonspecific markers: CRP, ESR, Procalcitonin Asepsis & Precautions Hand hygiene (most important) ● Soap/water when visibly soiled and for C. diff spores ● Alcohol sanitizer works unless hands visibly soiled Medical asepsis (clean technique) ● reduces microbes; includes isolation precautions Surgical asepsis (sterile technique) ● prevents introducing microbes during invasive procedures; uses sterile supplies/fields Isolation Precautions (major takeaways) Standard precautions ● For all clients ● Protect from blood/body fluids, secretions, excretions, nonintact skin, mucous membranes ● PPE based on expected exposure Contact precautions ● Gown + gloves ● Examples: C. diff, VRE, norovirus, RSV, large draining wounds ● Remove PPE inside room Droplet precautions ● Surgical mask ● Examples: influenza, pertussis, RSV Airborne precautions ● N95 or higher, private room; AIIR/negative pressure preferred ● Examples: TB, measles, varicella Protective isolation (protective environment) ● For severely immunocompromised (ex: post-allogenic HSCT) ● Positive airflow + HEPA (goal: protect the client) Health Care–Associated Infections (HAIs) — the “big 4” ● CLABSI ● CAUTI ● SSI ● VAP Devices/lines/wounds create portals of entry → strict asepsis reduces risk. MDROs (major concept) MDROs = resistant bacteria (hard to treat) Examples: MRSA, VRE, VRSA, VISA, ESBL, MDRSP Prevention: hand hygiene, contact precautions per policy. If you want, I can turn this condensed guide into a 20-question practice quiz (ATI/NCLEX-style) focusing on chain links, precautions, PPE, labs, and transmission. Week 6 Here is a more condensed study guide that keeps all main concepts from your content (no major topics removed), just simplified and streamlined for studying. Condensed Study Guide: Novice to Expert + Nursing Communication I. Novice to Expert Nursing (Benner Model) Lifelong Learning & Collaboration ● Learning occurs through study and working with others ● Nurses grow by: ○ observing experienced nurses ○ sharing knowledge and best practices ● Respect all experience levels (years ≠ only indicator of knowledge) ● Leaders promote: ○ collaboration ○ mutual respect ○ teamwork culture Benner’s 5 Stages of Competence 1. Novice – no experience; relies on rules; struggles to prioritize 2. Advanced Beginner – recognizes patterns; still rule-focused; needs help setting priorities 3. Competent – uses past experience to prioritize; more organized but slower than proficient 4. Proficient – sees the big picture; adapts to changing situations 5. Expert – intuitive, confident, and highly skilled with complex care II. Communication Foundations Definition Communication = transfer of information that is always occurring, even without speaking. Includes: verbal words, body language, emotions, and technology. Why Communication Matters ● Key to client safety (Joint Commission goal) ● Miscommunication → medical errors ● Nurses must detect when clients don’t understand III. Communication Models (Core Concepts) Shannon–Weaver Model (Linear) Sender → Encoder → Channel → Decoder → Receiver + Noise (distractions interfering with message) Schramm Model (Feedback) ● Sender and receiver exchange messages ● Feedback confirms understanding ● No feedback = communication incomplete Newcomb ABX Model (Social) ● A (sender), B (receiver), X (topic affecting interaction) ● Focus on relationships and shared topic Berlo S-M-C-R Model (One-way) ● Sender → Message → Channel → Receiver ● No feedback loop IV. Forms of Communication Verbal Spoken communication (face-to-face or phone) Nonverbal (Body Language) ● Eye contact, posture, facial expressions ● When verbal and nonverbal conflict → nonverbal dominates Auditory What the receiver hears (tone, speed, clarity) Emotional Speaker’s emotional state influences how message is received Energetic Speaker’s presence/empathy affects perception of message V. Modes of Communication (4 Types) 1. Verbal – spoken conversation 2. Nonverbal – gestures, posture, appearance 3. Electronic – email, text, video (must be secure/HIPAA compliant) 4. Written – letters, emails, documents (may lack tone/body language) HIPAA & Electronic Communication Must include: ● secure messaging ● unique logins ● auto logoff ● encrypted/indecipherable PHI VI. Communication Styles Most effective: Assertive ● Passive: avoids conflict; agrees despite concerns ● Assertive: clear, respectful, confident; uses “I” statements ● Aggressive: blaming, hostile, controlling ● Passive-aggressive: indirect expression (sarcasm, avoidance) VII. Therapeutic Communication Purpose Build trust and provide patient-centered, empathetic care Cornerstones ● Compassion ● Caring ● Empathy Peplau’s Nurse-Client Relationship Phases 1. Orientation – client seeks help 2. Identification – relationship forms 3. Exploitation – active teaching/working phase 4. Resolution – issue resolved; relationship ends Watson’s Theory of Human Caring ● Authentic presence ● Protect dignity ● Loving-kindness ● “Healing moment” interactions VIII. Therapeutic Communication Techniques (Must Know) ● Active listening – attend to verbal + nonverbal cues ● Open-ended questions – encourage discussion (“Tell me more…”) ● Silence – allows client to reflect and share more ● Restating / summarizing – repeat message to confirm understanding ● Reflection – mirror feelings (“What do you think you should do?”) ● Accepting – acknowledge message without judgment ● Giving recognition – note change without compliment ● Focusing – gently redirect to important topic ● Offering self – sit with client and be present IX. Nontherapeutic Communication (Avoid) ● Giving advice ● False reassurance (“You’ll be fine”) ● Criticizing or challenging ● Asking “Why” questions ● Rejecting or disagreeing ● Probing irrelevant topics ● Changing the subject Effects: ● increased stress ● damaged trust ● poor outcomes X. Interprofessional Communication Importance Effective teamwork improves: ● client outcomes ● safety ● efficiency ● reduces errors IPEC Core Competencies 1. Mutual respect among team members 2. Use shared knowledge collaboratively 3. Communicate effectively as a team 4. Support team values and client-centered care XI. Motivational Interviewing (MI) Purpose Encourage behavior change (diabetes, obesity, substance use) OARS Technique ● Open-ended questions ● Affirmations (positive encouragement) ● Reflective listening ● Summarizing XII. Group vs Individual Communication ● Individual: new diagnosis, personal teaching ● Group: ongoing education, support groups XIII. Communication Barriers (Major Categories) Cognitive/Developmental ● dementia, stroke, autism Physiological ● hearing loss, vision impairment Cultural & Language ● language differences, cultural beliefs, lack of cultural competence Environmental/Situational ● noise, lighting, temperature ● fear, anxiety, fatigue, stress Technological ● poor reception, distractions, electronic errors XIV. Strategies to Overcome Barriers Universal Strategies ● show empathy and respect ● avoid interrupting ● use simple, clear language ● confirm understanding (summarize/reflect) Language Barriers (CLAS Standards) ● Use qualified medical interpreter ● Do NOT use family members or translation apps ● Required for federally funded facilities Hearing Impairment Strategies ● face the client ● speak clearly/moderate pace ● reduce background noise ● use written info or visual aids ● ensure hearing aids in place ● speak to client (not interpreter) if interpreter present Vision Impairment Strategies ● introduce yourself ● give clear directions (“door at 10 o’clock”) ● allow client to hold your arm ● provide large print/audio/Braille materials Cognitive/Developmental Strategies ● use simple words ● avoid jargon/slang ● speak slowly and clearly ● reduce noise/bright distractions ● ensure glasses/hearing aids available Key Takeaways (Exam Focus) ● Benner’s stages: Novice → Advanced Beginner → Competent → Proficient → Expert ● Communication must include feedback to be effective ● Nonverbal cues often outweigh verbal messages ● Best communication style = Assertive ● Core therapeutic techniques = active listening, open-ended questions, silence, reflection, summarizing ● Use qualified interpreter for language barriers (CLAS standard) ● Barriers include cognitive, physical, cultural, environmental, and emotional factors ● Effective communication improves client safety and outcomes Here is a condensed but complete study guide that keeps all concepts from the Safety lesson while removing extra wording.

CONDENSED STUDY GUIDE: PATIENT-CENTERED CARE, CARING, CULTURE, ADVOCACY & SLEEP I. Patient-Centered Care Definition Patient-centered care = placing the client at the center of all care, focusing on preferences, culture, and holistic needs rather than just tasks or documentation. Key Concepts ● Improves client satisfaction and outcomes ● Involves caring, preferences, cultural respect, and shared decision-making ● Holistic care: physical, emotional, spiritual needs II. Caring in Nursing Definition Caring = nurturing another person with responsibility and commitment; core of professionalism. Holistic Caring Includes ● Healing environment ● Kindness, empathy, compassion ● Addressing physical, emotional, and spiritual needs III. Caring Theories A. Watson’s Theory of Human Caring Holistic model focusing on mind-body-spirit harmony through transpersonal (human-to-human) caring relationships.

Openness to spirituality and miracles B. Swanson’s Theory of Caring Caring improves well-being through empowerment, dignity, and respect. Five Caring Processes 1. Maintaining belief – instill hope and meaning 2. Knowing – understand client’s situation/perception 3. Being with – emotional and physical presence 4. Doing for – perform needed tasks for client 5. Enabling – guide and support through events/transitions IV. Caring Behaviors 1. Listening ● Active, empathetic listening ● Observe verbal and nonverbal cues ● Key for holistic assessment and trust 2. Touch ● Used for procedures and expressive caring ● Requires permission; consider culture, trauma, gender ● Can reduce anxiety and increase well-being 3. Being Present ● Physical and emotional availability ● Reduces loneliness and improves comfort ● Reflects “being with” (Swanson) 4. Providing Comfort ● Pharmacologic and nonpharmacologic comfort measures ● Examples: pillows, blankets, hygiene, music, temperature control ● Represents “doing for” 5. Showing Compassion ● Recognize suffering and act to relieve it ● View client as person, not diagnosis ● Requires self-awareness and adequate staffing V. Client Preferences in Care Clients are full members of the health care team and experts on their own experiences. Benefits ● Increased trust and satisfaction ● Improved healing and outcomes ● Greater sense of control Ways to Include Preferences 1. Endorsing participation – empower involvement 2. Promoting understanding – correct misinformation 3. Sharing information – two-way communication Barriers ● Power imbalance ● Medical jargon ● Weakness, fatigue, cognitive impairment ● Poor collaboration and language barriers VI. Cultural Competence Definition Evidence-based care aligned with client’s cultural values, beliefs, and practices. Influencing Factors ● Socioeconomic status ● Health literacy ● Racism experiences ● Sexual orientation ● Acculturation (adapting to another culture) Five Elements of Cultural Competence 1. Cultural awareness – self-examine biases 2. Cultural knowledge – learn client values/beliefs 3. Cultural skill – assess cultural needs accurately 4. Cultural encounters – interact with diverse cultures 5. Cultural desire – motivation to connect with cultures Cultural Assessment Includes ● Cultural/spiritual affiliation ● Health beliefs and practices ● Spiritual rituals ● Dietary preferences/prohibitions ● Care preferences to increase comfort VII. Age-Related (Generational) Care Preferences Generation Preferences Silent (1928–1945) Formal, face-to-face, written communication Baby Boomers Team-oriented, sincere, in-person communication Gen X Direct, independent, questions providers Millennials Tech-based communication, frequent feedback Gen Z Digital natives, prefer texting/email Gen Alpha Tech-savvy children; family-centered care VIII. Spiritual Nursing Care Spiritual Well-Being Feeling of meaning, purpose, and connection to higher power → improves quality of life.

Access to Care Barriers ● Lack of insurance ● Transportation problems ● Limited providers/facilities (rural areas) ● Restricted clinic hours ● Medication cost barriers Solutions ● Telemedicine: remote diagnosis/testing ● Telehealth: broader remote clinical and nonclinical services ● Improves access, especially rural areas XII. Client Advocacy Definition Protect client autonomy, rights, and safety; act as client’s voice. Clients Needing Advocacy ● Unconscious ● Children ● Fearful/intimidated clients ● Uninformed about diagnosis/rights Advocacy Steps 1. Assess needs, values, cognition, resources 2. Verify client goals/preferences 3. Implement plan and communicate with team 4. Evaluate outcomes and self-determination Related Concepts ● Medically futile: treatment unlikely to cure or extend life ● Potentially inappropriate treatment: works but may not improve quality of life ● Palliative care: symptom relief + quality of life ● Quality of life: personal meaning, independence, relationships XIII. Sleep and Rest Importance of Sleep Supports: ● Memory, learning, concentration ● Immune system and tissue repair ● Hormone balance (ghrelin, leptin, cortisol) ● Mood, reaction time, coordination ● Prevention of obesity, diabetes, cardiovascular disease XIV. Physiology of Sleep Key Brain Structures ● Cerebral cortex: sensory processing & memory ● Brainstem: controls REM and muscle relaxation ● Hypothalamus: autonomic control, circadian rhythm (SCN) ● Thalamus: sensory filtering during sleep ● Pineal gland: produces melatonin XV. Sleep Regulation Mechanisms 1. Circadian rhythm – 24-hour internal sleep–wake cycle influenced by light and temperature 2. Sleep–wake homeostasis – pressure to sleep increases with sleep deprivation Factors affecting sleep: ● Light exposure ● Stress ● Medications ● Caffeine/food ● Environment XVI. Stages of Sleep NREM Sleep Stage 1: Light sleep; easily awakened (5%) Stage 2: Deeper sleep; decreased HR/temp; memory consolidation (50%) Stage 3: Deep sleep; delta waves; immune strengthening and tissue repair (15%) REM Sleep ● Dream stage ● Irregular breathing and increased HR ● Muscle atonia (prevents acting out dreams) ● Occurs ~90 minutes after sleep onset Sleep cycles repeat 4–6 times per night. XVII. Sleep Patterns by Age ● Newborns: multiple cycles, high REM ● Adults: 2–5% stage 1, 45–55% stage 2, 10–20% stage 3, 20–25% REM ● Older adults: less deep sleep, more awakenings XVIII. Sleep Deprivation Types ● Total: no sleep for extended period ● Partial: reduced sleep hours ● Chronic: ongoing insufficient sleep ● Selective: loss of specific sleep stage Effects ● Impaired judgment and memory ● Mood swings, depression ● Increased accidents and chronic illness risk ● Poor glucose control and obesity XIX. Promoting Sleep Nonpharmacologic Interventions ● Avoid caffeine, nicotine, alcohol before bed ● Keep room dark, quiet, cool ● Establish bedtime routine ● Consistent sleep schedule ● Exercise regularly (not right before bed) ● Limit naps (<30 minutes) ● Remove electronics/TV from bedroom XX. Sensory Overload in Hospital Definition: Excess stimuli beyond brain’s processing ability → sleep disruption. Nursing Interventions ● Lower noise and alarms ● Dim lights ● Provide earplugs/eye masks ● Cluster care tasks ● Control pain and medication effects XXI. Sleep Disorders Insomnia Difficulty falling/staying asleep → fatigue, poor concentration, mood changes Sleep Apnea ● Central: brain fails to signal breathing ● Obstructive: airway collapse; snoring; daytime sleepiness Treatment: CPAP, weight loss, avoid alcohol/smoking Narcolepsy Sudden sleep attacks; possible cataplexy (loss of muscle tone) Hypersomnia Excessive daytime sleepiness despite adequate sleep Restless Legs Syndrome (RLS) Urge to move legs; worsens at night; disrupts sleep Night Terrors Non-REM parasomnia causing panic and no recall; common in children XXII. Pharmacologic Sleep Therapies ● Benzodiazepines (GABA agonists): sedative but dependency risk ● Nonbenzodiazepine hypnotics (most common) ● Melatonin: low-risk first-line option ● Antihistamines: OTC but cause side effects XXIII. Nonpharmacologic Sleep Therapies ● Massage, acupuncture, thermotherapy ● Guided imagery, meditation, music therapy ● Yoga and relaxation techniques ● Sleep diaries to identify patterns and personalize care FINAL KEY POINT Patient-centered nursing integrates: ● Caring theories ● Cultural competence ● Spiritual support ● Client advocacy ● Sleep and comfort promotion Goal: provide holistic care that supports physical healing, emotional well-being, spiritual meaning, autonomy, and optimal quality of life. Week 7 Absolutely—here’s a more condensed study guide that still includes every concept you were given. CONDENSED STUDY GUIDE: ELIMINATION (ALL CONCEPTS) 1) Big Picture ● Elimination (urine + stool) is continuous and essential. Patterns vary, but changes require assessment + intervention to restore usual patterns or establish a new baseline. 2) Urinary System Basics Functions: excrete waste/fluid → urine, regulate electrolytes, support RBC production, help regulate BP, support bone health. Pathway: kidneys → ureters → bladder → urethra → urination. Control: internal sphincter + external sphincter + pelvic floor muscles prevent leakage. Urination: elimination of urine via urethra. 3) Urine Production & Assessment Normal: clear, light yellow, minimal odor. Typical daily amount: ~1–2 quarts/day (varies). Expected output by age: infant ~2 mL/kg/hr; toddler ~1.5; teen ~1; adult ~0.5. Color clues: ● Dark yellow/amber = need fluids ● Dark brown = dehydration/kidney/liver concern ● Red/pink = blood or foods (beets, blackberries, rhubarb) Diet/med effects: ● Fluids ↑ volume, lighter color ● Asparagus ↑ odor ● Dyes can turn blue/green ● Alcohol + caffeine ↑ urine output (can dehydrate if not balanced) Aging urinary changes: ↓ nephrons/kidney function, ↓ bladder tone → incontinence/retention risks. 4) GI System Basics Organs: mouth → esophagus → stomach → small intestine → large intestine → rectum → anus. Peristalsis: contractions that move contents through GI tract. Feces formation: digestion + absorption (small intestine), water absorption + stool formation (large intestine), bacteria help + make vitamin K, rectum stores stool until BM. Bristol Stool Chart: ● Types 1–2 = constipation ● Types 3–4 = expected ● Types 5–7 = diarrhea Aging GI changes: ↓ peristalsis/muscle tone → constipation; ↑ PUD risk (NSAIDs), ↓ elasticity/emptying changes, possible ↓ absorption/bacterial overgrowth, ↓ lactase → lactose intolerance; lifestyle factors (inactivity, low fiber/fluids, meds) contribute. 5) Expected Elimination ● Urine: clear, light yellow, varies with intake/activity/diuretics. ● Stool: frequency varies widely; should be soft/formed, easy to pass without straining. 6) Altered Urinary Elimination Urinary Incontinence (UI) Involuntary urine loss. Can cause skin breakdown + distress. Types: ● Stress: cough/sneeze/exertion ● Urge: sudden urge, leak before toilet ● Reflex: nerve damage, no warning ● Overflow: incomplete emptying → overfill/leak ● Functional: can’t reach toilet (mobility/dexterity issues) ● Nocturnal enuresis: nighttime (kids; adults w alcohol/caffeine/meds) Management: lifestyle changes (↓ caffeine/alcohol, smoking cessation, address constipation), pelvic floor exercises, bladder training, meds/devices/surgery; skin protection (pads/briefs, cleanser, barrier cream). Urinary Retention Incomplete bladder emptying (acute or chronic). Causes: BPH, cystocele/prolapse, obstruction (stones/lesions). Findings: hesitancy, weak stream, frequency, distention, pain, leakage. Risks: UTI, bladder/kidney damage. 7) Altered Bowel Elimination Constipation <3 BMs/week + hard/lumpy stools, difficult to pass. Risks: pregnancy/postpartum, older adults, low fiber/fluids, meds, GI disorders, immobility. Red flags: fever, GI bleeding, severe pain, vomiting, weight loss. Complication: fecal impaction/obstruction (liquid stool may leak around impaction). Tx: fiber + fluids + exercise + bowel training; meds; enema/manual removal; surgery if complete obstruction. Diarrhea Frequent loose/watery stools: acute (1–2d), persistent (>2w <4w), chronic (>4w). Risks: infection, meds, GI disorders, diet. Dangers: dehydration, malabsorption. Adult urgent follow-up: fever ≥102°F, >2 days, ≥6/day, severe pain, blood/black stool. Tx: rehydration; OTC (loperamide/bismuth) if appropriate; antibiotics/probiotics if infectious cause. Bowel Incontinence Urge (can’t reach toilet) most common; passive (unaware leakage). Leads to skin issues + reduced self-esteem. Children: encopresis. 8) Medications That Affect Elimination Constipation: antacids (Al/Ca), anticholinergics/antispasmodics, antiseizure meds, Ca-channel blockers, diuretics, iron, antiparkinsonian, opiates, antidepressants. Diarrhea: antibiotics, magnesium antacids; consider C. diff if severe/persistent after antibiotics. 9) Conditions Altering Urinary Patterns ● Dehydration: thirst, dry mouth, fatigue, dizziness, dark urine; severe needs IV fluids. ● UTI: dysuria, urgency/frequency; can progress to pyelonephritis (fever, flank pain, N/V, hematuria). Tx antibiotics + fluids. Higher risk: females, retention, obstruction, catheters, diabetes, menopause. ● Kidney stones: severe flank pain radiating to groin, hematuria, dysuria, fever/chills, N/V. Tx fluids, pain meds, strain urine, ESWL/surgery. ● Kidney failure: waste/fluid buildup → ↓ urine, HTN, anemia, itching; Tx dialysis or transplant. ● BPH: urethral constriction → retention, nocturia, weak stream; can cause UTIs/damage; Tx meds/surgery. 10) Conditions Altering Bowel Patterns ● Diverticulosis: pouches; Diverticulitis: inflamed/infected pouch → pain/bleeding; risk perforation → peritonitis. Prevent: fiber; nuts/seeds no longer restricted. Tx antibiotics + liquid/soft diet. ● IBS: pain + diarrhea/constipation (IBS-C, IBS-D, IBS-M); Tx diet (fiber/probiotics, avoid triggers), stress reduction, sleep/exercise, meds. ● Bowel obstruction: blockage → N/V, distention, severe constipation; NG decompression + surgical consult. ● Ileus: decreased/absent motility (often post-op/illness/meds) → absent bowel sounds, distention, N/V; Tx NPO, NG tube, IV fluids; consider TPN if prolonged. ● Ulcerative colitis: colon inflammation/ulcers → bloody diarrhea, fatigue, anemia; Tx meds; surgery if refractory/cancer risk. ● Crohn’s: inflammation anywhere (often small intestine) → diarrhea, weight loss, anemia; complications fistulas/abscess/obstruction; Tx meds + possible surgery. 11) Diversions & Ostomies Urinary Diversions ● Catheterization (temporary) ● Ureteral stent ● Ileal conduit/urostomy (stoma + pouch) ● Nephrostomy (kidney → external bag) ● Neobladder (internal reservoir, may need catheter) ● Continent cutaneous reservoir (internal pouch + valve; catheter to empty) ● Cystostomy (catheter directly into bladder) Complications: UTIs, kidney infection, skin breakdown; psychosocial concerns. Fecal Diversions ● Ileostomy ● Colostomy (+ irrigation option for some permanent colostomies) ● J-pouch (internal ileal reservoir connected to anus; often temporary ileostomy first) ● Kock pouch (continent ileostomy; catheter to empty) Complications: skin irritation, hernia/prolapse/stenosis, blockage, diarrhea, bleeding, electrolyte imbalance, infection, leakage. WOC nurse supports education + supplies + skin/stoma care. 12) Diagnostics & Specimen Collection Urinary ● Urodynamics: uroflowmetry, postvoid residual, cystometric test, leak point pressure, EMG, video urodynamics, pressure-flow study ● Scopes: cystoscopy, ureteroscopy ● Urinalysis: visual + dipstick + microscopic (WBC, RBC, bacteria, casts, crystals) ● Urine culture: clean catch midstream; grows organism + susceptibility testing (correct antibiotic; reduces resistance) ● 24-hour urine: collect all urine, refrigerate, avoid certain foods/meds Urine collection methods: clean catch vs catheter (sterile technique for intermittent/indwelling). GI ● Tests: celiac testing, colonoscopy, ERCP, sigmoidoscopy, upper/lower GI series, upper endoscopy ● FOBT: dietary/med restrictions to prevent false positives (ex: beets, red meat, some veggies; aspirin/ibuprofen/Vit C) ● Stool culture: for severe/persistent diarrhea (travel, contaminated food/water, antibiotics) 13) Nursing Interventions Promote Urinary Elimination ● Bedpan/urinal assistance + measure output + privacy + skin check ● Bladder irrigation (ordered; pain is NOT expected → report) ● Lifestyle: avoid bladder irritants; appropriate fluids; weight loss; stop smoking ● Bladder training + elimination journal ● Bladder scan to avoid unnecessary catheterization ● Catheters: intermittent, indwelling, external male condom, external female wick ● CAUTI prevention: sterile insertion for indwelling/intermittent; daily hygiene; handwashing; keep system clean Promote Bowel Elimination ● Fiber, hydration, activity, respond to urge, stress management ● Bowel training (may use laxatives) ● Enemas: cleansing vs retention; solutions hypotonic/isotonic/hypertonic (tap water can cause electrolyte shifts) ● Laxatives: ○ Bulk-forming ○ Surfactant (stool softener) ○ Stimulant ○ Osmotic ● Rectal tubes/fecal management systems for severe incontinence Skin Care for Incontinence ● Clean promptly, rinse, pat dry ● Moisturize (alcohol-free) ● Barrier ointments/pastes/sealants ● Assess for nonblanchable redness, blisters, wounds/ulcers NG Decompression (for obstruction/ileus) Measure nose → ear tragus → xiphoid, advance with swallowing, confirm placement (x-ray/capnography/pH per policy), secure + suction as ordered. If you want, I can also turn this into a 1-page “exam cram” sheet (still including every concept, just in ultra-compact bullets). Condensed Study Guide: Main Concepts (Elimination + Sensory Perception) 1) ELIMINATION (URINARY + BOWEL) Urinary system basics ● Organs: kidneys → ureters → bladder → urethra ● Kidneys: filter blood, remove waste/fluid, regulate electrolytes & BP hormones, support RBC production. ● Normal urine: clear, light yellow, minimal odor. ○ Dark yellow/amber: dehydration. ○ Red/pink: blood or foods (beets). ○ Brown: severe dehydration/liver/kidney issues or certain foods. Expected urine output (high-yield) ● Adults: ~0.5 mL/kg/hr ● Output generally decreases with age (↓ nephrons, ↓ renal blood flow). Urinary alterations Urinary incontinence = can’t control urination Types: ● Stress: cough/sneeze/exertion → leak ● Urge: sudden strong urge → can’t reach toilet ● Overflow: bladder overfills from incomplete emptying → dribbling/leak ● Reflex: nerve damage → unpredictable leakage ● Functional: can’t get to toilet in time (mobility/dexterity issues) ● Nocturnal enuresis: nighttime bedwetting Key nursing focus: skin protection (barrier creams, briefs/pads), reduce irritants, bladder training, pelvic floor exercises. Urinary retention = can’t empty bladder fully ● Causes: BPH, prolapse (cystocele), obstruction (stones), neuro issues. ● Findings: hesitancy, weak stream, frequency, distention, pain, leakage. ● Risks: UTI, bladder/kidney damage. ● Interventions: identify cause, drain bladder if needed, bladder scan, catheterization if ordered. Common urinary conditions ● Dehydration: thirst, dry mouth, dizziness, dark urine, low urine; severe → IV fluids. ● UTI: dysuria, urgency/frequency; untreated → pyelonephritis (fever, flank pain, N/V). Treat: antibiotics + fluids. ● Kidney stones: severe flank pain radiating to groin, hematuria, N/V; treat pain + fluids, strain urine, possible lithotripsy/surgery. ● Kidney failure: ↓ urine, HTN, anemia, itching; treat dialysis/transplant. ● BPH: frequency/nocturia, weak stream, retention/incontinence; treat meds/surgery. Bowel system basics ● GI tract: mouth → esophagus → stomach → small intestine → large intestine → rectum → anus ● Peristalsis moves contents forward. ● Stool: should be soft/formed, easy to pass (no straining). Bristol Stool Chart (quick) ● 1–2: constipation (hard/lumpy) ● 3–4: ideal/normal ● 5–7: diarrhea (loose/watery) Bowel alterations ● Constipation: <3 BMs/week + hard stool/straining ○ Risks: impaction/obstruction (esp immobile/neuro injury). ○ Tx: fiber, fluids, activity, bowel training, stool softeners/laxatives; impaction → enema/manual removal. ● Diarrhea: frequent loose watery stools ○ Danger: dehydration, electrolyte imbalance; red flags: blood/black stool, fever, severe pain, lasts >2 days. ○ Tx: rehydration, remove irritants; meds like loperamide (if appropriate); infection → meds/probiotics as ordered. ● Bowel incontinence: urge (can’t reach toilet) vs passive (leak without awareness). ○ Nursing: skin care, scheduled toileting, bowel training, protect dignity. Diversions (know names + purpose) Urinary diversions ● Catheterization: intermittent or indwelling ● Ureteral stent: keeps ureter open ● Urostomy/ileal conduit: urine exits through stoma into pouch ● Nephrostomy: kidney → external drainage ● Cystostomy (suprapubic): catheter directly into bladder ● Neobladder/continent reservoir: internal storage; may need catheter to empty Complications: infection, skin breakdown, psychosocial stress. Fecal diversions ● Ileostomy: ileum → stoma (often liquid stool) ● Colostomy: colon → stoma (more formed depending on location) ● J-pouch: internal ileal reservoir connected to anus ● Kock pouch: continent ileostomy; catheter to empty Complications: skin irritation, leaks, hernia/prolapse, blockage, diarrhea, electrolyte issues. Diagnostic tests/specimens (high-yield) Urinary ● Urinalysis: dipstick + microscopic ● Urine culture: clean catch; susceptibility testing picks the right antibiotic ● 24-hr urine: measures substances over time ● Urodynamics: bladder function (uroflowmetry, PVR, cystometrics, etc.) ● Cystoscopy/ureteroscopy: visualize urinary tract GI ● FOBT: check hidden blood (avoid foods/meds that cause false positives) ● Stool culture: severe/persistent diarrhea, travel, prolonged antibiotics ● Colonoscopy, sigmoidoscopy, upper GI endoscopy, ERCP, GI series as indicated Nursing priorities (elimination) ● Assess: amount, frequency, color/odor, pain, stool type. ● Prevent skin breakdown: cleanse, dry, barrier creams, frequent checks. ● Promote normal patterns: hydration, fiber, activity, timed toileting, privacy, proper equipment (bedpan/urinal). ● Reduce infection risk: sterile technique for invasive catheters; minimize indwelling catheter days (CAUTI prevention). 2) SENSORY PERCEPTION (ALL MAIN CONCEPTS) Big picture ● Stimulus → sensory organ → CNS/cranial nerves → brain interprets → response ● Problems can be in reception, perception, or response. Key terms ● Sensory deficit: reduced function (vision/hearing/touch/etc.) ● Sensory deprivation: too little stimulation ● Sensory overload: too much stimulation → anxiety/confusion ● SPD: detects stimuli but brain misprocesses → oversensitive/overwhelmed Cranial nerves (only what’s essential) ● I smell, II vision, III/IV/VI eye movement ● V facial sensation/jaw ● VII facial expression + taste (front tongue) ● VIII hearing/balance ● IX/X swallowing/gag/voice ● XI shoulder shrug/head turn ● XII tongue movement Vision: most tested disorders ● Refractive errors: myopia, hyperopia, astigmatism, presbyopia ● Cataracts: cloudy lens → blurry/hazy, ↓ color ● Diabetic retinopathy: retinal vessel damage → floaters/blur → blindness risk ● Glaucoma: ↑ intraocular pressure → loss of peripheral vision (irreversible) ● Macular degeneration: loss of central vision (older adults) Tests: Snellen/Tumbling E; slit lamp; fluorescein angiography; visual field test; intraocular pressure; Amsler grid. Hearing ● Anatomy: outer → middle (ossicles) → inner (cochlea) → CN VIII. ● Tinnitus: ringing/buzzing without sound. ● Types of loss: ○ Sensorineural: inner ear/nerve (aging = presbycusis, loud noise, ototoxic meds) ○ Conductive: sound can’t travel (wax, otitis media, perforation, otosclerosis) ○ Mixed: both Tests: Rinne, pure-tone audiometry; ABR/OAE (screening). Speech/Aphasia (stroke-related high yield) ● Broca/expressive: understands but can’t produce words well (“telegraphic” speech) ● Wernicke/fluent: lots of words, no meaning; poor comprehension ● Global: severe impairment of both Touch ● Hypersensitivity / defensiveness (painful to normal touch) vs hyposensitivity (reduced pain/temp). ● Major causes: peripheral neuropathy (diabetic), spinal cord injury. ● Testing: neuro exam, sensation checks, nerve conduction, EMG, MRI. Smell & taste (often linked) ● Taste disorders: hypogeusia (↓ taste), ageusia (no taste), dysgeusia (metallic/rancid), phantom taste ● Smell disorders: anosmia (no smell), hyposmia (reduced), parosmia (distorted), phantosmia (smell not real) ● Causes: URIs, sinus disease, head injury, smoking, meds, zinc deficiency, neuro disorders. Aging effects (must know) ● Vision & hearing decline most. ● Vision: smaller pupils, less lens flexibility, weaker extraocular muscles, ↓ tears/dry eyes. ● Hearing: high-frequency loss, cerumen impaction, tinnitus. ● Taste/smell: ↓ taste buds + ↓ saliva → ↓ appetite → malnutrition risk. ● Touch: ↓ circulation → ↓ temperature/pain sensitivity. Nursing priorities (sensory) ● Safety + independence + emotional support ● Vision: lighting, corrective lenses, remove clutter, orient to room, fall prevention. ● Hearing: face client, reduce background noise, check hearing aids, use written info/interpreter. ● Speech: allow time, don’t finish sentences, use boards/paper/tablet. ● Touch: injury prevention (diabetic foot care, protective footwear, daily inspection). ● Smell/taste: oral hygiene, season foods, smoke/CO detectors, avoid smoking. If you want, I can turn this into a one-page “test-ready” version (even shorter, like only definitions + red flags + key interventions). Condensed Study Guide: Complementary & Integrative Health (CIH) / CAM / Holistic Nursing 1) Key Terms (know the differences) ● Conventional (Western) medicine: Evidence-based diagnosis & treatment (meds, surgery, radiation). Also called mainstream, allopathic, biomedicine, orthodox. ● Complementary therapy: Used with conventional care (ex: aloe + NSAID for sunburn). ● Alternative therapy: Used instead of conventional care. ● Integrative health: Combines conventional + complementary + alternative in a coordinated plan (mind–body–spirit). ● Holistic nursing: Client-centered care treating the whole person (physical, emotional, spiritual, social, cultural, environment). Focus is healing + wellness, not just curing disease. 2) NCCIH Categories (how CIH is “delivered”) Nutritional approaches ● Herbs/botanicals, supplements, vitamins/minerals, probiotics, dietary therapies ● Usually OTC and labeled as dietary supplements Psychological (mind–body) approaches ● Relaxation, meditation, mindfulness/MBSR, guided imagery, biofeedback, hypnosis, prayer Physical approaches ● Hands-on body structures/systems: massage, chiropractic, osteopathy, spinal manipulation, heat/cold, reflexology Bioenergetic (energy) therapies ● Veritable energy = measurable EM fields/light/magnets ● Putative energy (biofields) = subtle energy concepts ● Examples: Healing Touch, Therapeutic Touch, Reiki, Tai Chi, qi gong, acupressure Whole medical systems ● Complete systems separate from Western medicine: ○ Ayurveda, Traditional Chinese Medicine (TCM), Unani, Kampo ○ Also: Homeopathy, Naturopathy, Functional medicine (root-cause focus) Combined approaches ● Blends multiple categories: yoga, mindfulness eating, dance/art/music therapy 3) Why it matters (nursing relevance) ● Many clients use CIH (often alongside prescriptions). Nurses must: ○ Assess what clients use ○ Prevent interactions/harms ○ Provide culturally congruent care ○ Support self-care + empowerment ● Holistic nursing priorities ○ Promote wellness, honor caring–healing relationship ○ Respect subjective experience of illness/healing ○ Encourage informed decisions + active participation ○ Incorporate cultural beliefs/folk practices safely 4) High-yield Mind–Body Therapies (what they do) ● Deep breathing: control rate/depth → ↓ anxiety/stress ● Meditation: quiet mind/focused attention → ↓ BP/HR, ↓ stress effects ● Mindfulness: present-moment awareness; can reduce stress and improve coping ● Guided imagery: mental visualization → relaxation, pain/anxiety reduction ● Prayer: spiritual coping/connection (client-defined) ● Progressive relaxation: systematically tense/relax muscle groups ● Yoga (meditative movement): poses + breathing ± meditation → stress, sleep, anxiety; also pain (back/neck) support ● Aromatherapy: essential oils (inhaled/topical) → relaxation, anxiety relief; some evidence for nausea (ex: ginger/lavender/peppermint blends) ● Acupuncture/acupressure: stimulates points/meridians → pain, nausea, fatigue, anxiety support ● Hypnotherapy: focused attention + suggestion → phobias, anxiety, pain, habits (smoking) ● Biofeedback: device-assisted control of body functions (HR, tension) → stress, headaches, rehab, pain 5) Manual Therapies (hands-on) ● Massage: manipulates soft tissues → pain/anxiety/insomnia support ○ Precautions: avoid over clots/tumors/prostheses; caution with anticoagulants/low platelets (bruising/bleeding); older adults risk (rare) fractures ● Reflexology: foot/hand zones thought to correspond to body functions ● Chiropractic: spinal manipulation + structural focus; no surgery/Rx meds ● Osteopathic medicine: structure-function relationship; osteopathic manipulation used by trained physicians 6) Bioenergetic / Movement Therapies ● Tai Chi / Qi gong: meditative movement; balance, function, stress reduction ● Alexander Technique: posture/neck-spine alignment awareness → chronic pain support ● Feldenkrais: mindful movement retraining → pain + mobility ● Rolfing/Structural integration: deep tissue/fascia work → posture/function ● Pilates: core/torso control, posture → balance, flexibility, pain relief ● Therapeutic Touch / Healing Touch / Reiki: energy-based touch; may support relaxation, pain reduction, agitation (ex: dementia) 7) Traditional / Indigenous Practices (cultural competence) ● Traditional medicine (WHO concept): culture-based knowledge/practices for prevention/diagnosis/treatment—often includes spirituality. ● Examples: Native healing practices (prayer, drumming, storytelling, sacred rituals), herbal use, cupping, etc. ● Nursing: respect beliefs, ask what practices are important, integrate safely. 8) Whole Medical Systems (quick ID) ● Ayurveda: balance mind–body–spirit; doshas; cleansing + diet + herbs + yoga/meditation ● TCM: acupuncture, Tai Chi/qi gong, herbs; balance yin/yang + qi flow ● Naturopathy: “body heals itself” supported by diet, lifestyle, herbs, supplements, homeopathy, etc. ● Homeopathy: “like cures like,” highly diluted remedies ● Functional medicine: root-cause, systems-based approach 9) Natural Products: BIG SAFETY POINTS (test favorites) FDA/supplements ● FDA regulates supplements, but manufacturers are responsible for quality/claims → variability exists. ● “Natural” ≠ safe. Must-do nursing action ● Always ask about herbs/supplements/vitamins OTC. ● Encourage a current med + supplement list shared with provider/pharmacist before starting anything new. Common interaction themes ● Bleeding risk (esp with anticoagulants like warfarin): ○ Garlic, ginger, ginkgo, cranberry (large amounts), evening primrose oil, etc. ● Serotonin syndrome risk when mixing certain herbs with antidepressants: ○ St. John’s wort + antidepressants (ex: duloxetine) ● CNS depression/sedation combos: ○ Valerian + sedatives/alcohol/antihistamines ● Vitamin K decreases warfarin effect: ○ Leafy greens (consistency matters) Specific high-yield herbal cautions ● Ephedra (ma huang): banned in U.S. supplements → serious CVA/MI risk (worse with caffeine) ● Kava: can cause liver damage ● Black cohosh: possible liver injury risk ● Tea tree oil: toxic if ingested ● Licorice root: ↑ BP, can lower K+ (esp with diuretics); avoid in pregnancy ● St. John’s wort: many interactions (reduces effectiveness of multiple meds) + photosensitivity Probiotics (basic) ● Support healthy gut flora; can help inhibit harmful bacteria (ex: Lactobacillus) 10) Vitamins & Minerals (core test facts) Vitamins ● Water-soluble: B-complex + C (not stored well → need regular intake) ● Fat-soluble: A, D, E, K (stored in fat/liver → toxicity risk if too much) Vitamin K newborn note: doesn’t cross placenta well; newborns get IM vitamin K to prevent bleeding. B-complex quick purpose (big picture) ● Mostly metabolism/energy, neuro function, RBC formation ● B12: neuro + RBCs (deficiency → anemia, fatigue, neuro changes) Minerals (core roles) ● Needed for: enzyme function, nerve/muscle contraction, fluid balance, bone/teeth ● Examples: ○ Calcium: bones + clotting + nerve impulses ○ Sodium: extracellular fluid, nerve/muscle ○ Potassium: nerve/muscle; high/low can cause arrhythmias ○ Magnesium: metabolic processes; low with alcohol use disorder/DM ○ Iron: oxygen transport; deficiency → anemia Food-drug/nutrient interactions (quick) ● Vitamin C ↑ non-heme iron absorption ● Coffee/tea/wine (polyphenols) + phytic acid (legumes/nuts) ↓ iron absorption Quick “Exam-Style” Reminders ● Complementary = with conventional; Alternative = instead; Integrative = coordinated blend. ● Nursing role: assess use, prevent interactions, educate, support self-care, respect culture. ● Biggest safety issue: herb/supplement interactions (bleeding, serotonin syndrome, sedation, warfarin/vit K).
