Comprehensive Study Guide: Clinical Nursing Procedures, Skin Integrity, Nutrition, Hydration, and Culturally Safe Care

CULTURALLY SAFE CARE AND DIVERSITY IN HEALTHCARE

• Cultural Diversity Overview:

  • Cultural diversity encompasses the unique differences that exist among individuals and population groups, including language, spiritual beliefs, traditions, health expectations, customs, values, and level of involvement in healthcare.

  • Person-centred care requires nurses to recognize and respect these differences to tailor interventions to individual patient needs.

• Demographic Profile (Western Australia and Australia):

  • In Western Australia, $35\%$ of the population was born overseas, over 300 languages are spoken, and $3.1\%$ of Australia's total Aboriginal and Torres Strait Islander population resides in the state.

  • Nationally, $30\%$ of Australia's total population was born overseas (2020 statistics).

• Nursing Responsibilities in Cultural Safety:

  • Without culturally safe practice, nursing care risks compromising the legitimate cultural rights, values, and expectations of Culturally and Linguistically Diverse (CaLD) individuals.

  • Nurses must maintain continuous self-awareness regarding their own personal cultural values, beliefs, attitudes, and outlooks that may consciously or unconsciously influence their clinical behaviors.

  • Nurses are required to educate and support CaLD patients, families, and communities to assist them in navigating the healthcare system effectively.

• Enrolled Nurse Standards for Practice (NMBA 2016):

  • The Nursing and Midwifery Board of Australia (NMBA) mandates that Enrolled Nurses uphold patient rights, confidentiality, dignity, and respect.

  • Standard 2.4: Mandates that Enrolled Nurses "Practise culturally safe care for (i) Aboriginal and Torres Strait Islander peoples and; (ii) people from all other cultures."

• Addressing Language Barriers in Healthcare:

  • Language barriers severely affect health literacy, informed consent, and health outcomes, frequently leading to the under-representation of CaLD populations in care facilities.

  • Interpreting and Translation Services:

    • Translating and Interpreting Services Centre (TISC): Provided for formal clinical consultations.

    • Hospital Service Providers (HSP): Multilingual staff members acting within scope.

    • Consumer and Carer Services: Involving family members or close community contacts when appropriate.

    • Digital Translation: Utilization of secure internet and smart-phone translation tools.

    • Written Materials: Patient information, consent documents, and brochures supplied in the patient's primary language. The Australian Charter of Healthcare Rights is translated into 17 languages.

ABORIGINAL AND TORRES STRAIT ISLANDER HEALTH AND CULTURAL SAFETY

• Terminology Protocol in Western Australia:

  • In Western Australia, the term Aboriginal is preferred over Aboriginal and Torres Strait Islander in state policy documents to acknowledge Aboriginal people as the original inhabitants of Western Australia. Aboriginal and Torres Strait Islander is used in national contexts, and Indigenous in international contexts.

• WA Aboriginal Health & Wellbeing Framework 2015-2030:

  • Five Dimensions of Holistic Health:

    1. Physical health

    2. Psychological health

    3. Social health and wellbeing

    4. Spirituality

    5. Cultural integrity

  • Six Guiding Principles:

    1. Cultural security: Identifying and responding to cultural needs within a holistic framework connected to country, culture, and community.

    2. Health is everybody's business: Embedding Aboriginal health needs into core business across all health sectors.

    3. Partnerships: Coordinated two-way skill exchange and collaboration between government, non-government, and Aboriginal community-controlled health organizations.

    4. Aboriginal community control and engagement: Supporting Aboriginal leadership and decision-making in service design and delivery.

    5. Access and equality: Ensuring health services are physically, economically, and culturally accessible.

    6. Accountability: Monitoring performance indicators, embedding evaluations, and ensuring transparent governance.

• Aboriginal Health Demographics and Statistics (WA):

  • Age Profile: Median age is $24\text{ years}$ for Aboriginal people compared to $37.8\text{ years}$ for non-Aboriginal people. This reflects higher birth rates and reduced life expectancy.

  • Population: Aboriginal people constitute $3.4\%$ of the WA population; $62\%$ live in rural or remote areas.

  • Life Expectancy Gap: Life expectancy is $15.1\text{ years}$ lower for Aboriginal men and $13.5\text{ years}$ lower for Aboriginal women compared to non-Aboriginal Australians.

  • Burden of Disease: Top five contributing categories are Mental/Substance Use Disorders, Injuries (including suicide), Cardiovascular Diseases, Cancer, and Respiratory Diseases. Potentially modifiable risk factors account for $49\%$ of this burden.

  • Avoidable Mortality: Chronic diseases account for $80\%$ of the mortality gap between ages 35 and 74, with onset occurring up to 20 years earlier than in non-Aboriginal populations.

  • Psychological Distress: $17\%$ of individuals aged 2 years and over experience anxiety, and $13\%$ experience depression. Furthermore, $46\%$ live with at least one chronic condition, and $37\%$ of children aged 2–14 are overweight or obese.

• Support Services and Community Control:

  • Aboriginal Liaison Officers (ALO): Provide culturally safe bedside support, advocacy, and navigation within hospital systems.

  • Aboriginal Community Controlled Health Organisations (ACCHOs): Primary healthcare bodies initiated and operated by local Aboriginal communities.

  • NACCHO: National peak body representing 144 ACCHOs across Australia.

CONGRESS OF ABORIGINAL AND TORRES STRAIT ISLANDER NURSES AND MIDWIVES (CATSINaM)

• Organizational Role and Purpose:

  • CATSINaM is the peak national advocacy body representing Aboriginal and Torres Strait Islander nurses and midwives.

  • Primary Functions:

    • Promote the recruitment, retention, and professional development of Aboriginal and Torres Strait Islander healthcare workers.

    • Implement systemic strategies to embed cultural safety across Australian healthcare systems and educational institutions.

    • Provide advocacy and support to mitigate workplace racism and discrimination experienced by Indigenous health staff.

NURSING DOCUMENTATION, LEGAL STANDARDS, AND CARE ELEMENTS

• Medicolegal and Professional Purpose of Documentation:

  • Serves as a permanent, contemporaneous, legally binding record of all patient care, clinical assessments, interventions, and evaluations.

  • Facilitates interdisciplinary communication and continuity of person-centred care.

  • Functions as legal evidence in court proceedings, an auditing tool for organizational compliance, an educational resource, and a source for clinical research.

• Governance and Practice Standards:

  • NSQHS Standard 6 (Communicating for Safety - Action 6.11): Mandates health service organizations to maintain robust processes for contemporaneously documenting critical info, alerts, risks, reassessments, and care plan modifications.

  • NMBA Code of Conduct for Nurses (Principle 3.3d): Requires accurate, clear, and timely communication of patient info within legal privacy limits.

  • NMBA EN Standard 7: Dictates that the Enrolled Nurse accurately communicates and uses documentation to inform and report care.

• The CARE Principles of Documentation:

  • Compliant and Complete: Adheres strictly to institutional and professional standards; documents daily progress, care plan revisions, and discharge summaries without leaving blank sections.

  • Accessible and Accurate: Readily available to authorized clinicians at the point of care; precisely reflects physical and clinical events.

  • Readable: Legible handwriting or formatted digital entries; standard English with proper spelling and grammar; avoids ambiguous abbreviations.

  • Enduring: Materially durable paper/electronic records that maintain long-term integrity and legibility for future readers.

DOCUMENTATION FORMATS, MEDICAL TERMINOLOGY, AND CLINICAL RECORDING

• Essential Principles of Entry Construction:

  • Must be recorded in chronological order using the 24-hour clock, dated, and timed.

  • Written in permanent black ink (for paper records).

  • Objective Entries: Factual, measurable clinical observations (e.g., vital signs, physical inspection).

  • Subjective Entries: Verbatim statements from the patient enclosed in quotation marks (e.g., Patient states "I feel dizzy").

  • Signature Protocol: Must be signed with author's full signature, printed surname, and professional designation (e.g., [signature (SMITH) Student Enrolled Nurse]). Student entries must be countersigned by a supervising Registered Nurse.

  • Error Correction: Draw a single horizontal line through the error, write "written in error" above or beside it, and initial the correction. Never use white-out/correction fluid, erase, or obscure entries.

• Documentation Models:

  • Documentation by Inclusion: Charting all routine and non-routine care rendered.

  • Documentation by Exception: Recording only significant, abnormal, or unexpected clinical findings, assuming standard protocol care was delivered normally unless noted otherwise.

    • E (Evaluation): Clinical outcome/response to interventions.

    • R (Reassessment): Review of ongoing patient status.

  • PIE Model: Problem identification, Interventions executed, Evaluation of treatment effectiveness.

• Medical Terminology Distinctions:

  • Aphasia (complete loss of speech) vs. Aphagia (inability to swallow) vs. Dysphasia (difficulty speaking) vs. Dysphagia (difficulty swallowing).

  • Perineal (pertaining to the perineum) vs. Peroneal (pertaining to the fibula/outer lower leg).

  • Ileum (distal portion of small intestine) vs. Ilium (superior wing of pelvic bone).

• Standard Clinical Abbreviations:

  • BD (twice daily), QID (four times daily), TDS (three times daily), IM (intramuscular), IV (intravenous), NPO (nothing by mouth).

SKIN INTEGRITY ASSESSMENT AND PREVENTATIVE STRATEGIES

• Anatomy and Physiology of Skin:

  • The skin is the body's largest organ, encompassing the cutaneous layer, hair, nails, sweat glands, and sebaceous glands.

  • Primary Functions: Protection against pathogens/trauma, fluid homeostasis, thermoregulation, sensory transmission (pain, pressure, thermal contact).

• Skin Integrity Definition:

  • Refers to healthy, undamaged cutaneous tissue that is non-vulnerable to injury, capable of normal tissue repair, and functions as an intact protective barrier.

• Protective and Risk Factors:

  • Protective Factors: Optimal protein/caloric nutrition, daily emollient hydration, protective gloves for physical tasks, independent ambulation (walking every 2 hours), muscle strength for limb lifting, correct posture, safe manual handling, and strict adherence to bare-below-the-elbow nursing protocols.

  • Predisposing Risk Factors: Pressure, friction, shear, impact forces, excess moisture (incontinence/perspiration), immobility, sensory loss, advanced age, extremes of body composition, malnutrition, vascular comorbidities, medical adhesives, and unsafe surroundings.

• Systematic Assessment Protocol:

  • A comprehensive skin assessment must occur within 8 hours of presentation/admission to an acute health facility or during the initial community visit.

  • Assessment Scope: Head-to-toe systematic inspection covering the entire body surface, hair, nails, anatomical skin folds, interdigital web spaces, and existing wounds.

• Clinical Forms and Assessment Parameters:

  • WACHS Form MR111 (Nursing Admission, Screening & Assessment Tool - Adults): Initial screening tool.

*   **WACHS Form MR124B** (*Comprehensive Skin Assessment*): Used for ongoing daily reassessment.

*   **Assessment Parameters & Coding**:
    *   *Temperature*: Normal, Cooler than normal (`C`), Warmer than normal/hot (`W`), Hot/very inflamed (`H`).
    *   *Moisture*: Normal, Dry (`D`), Moist to touch (`M`).
    *   *Turgor*: Gently lift dorsal hand skin. Normal ($<3\text{ seconds}$ recoil), Impaired ($>3\text{ seconds}$ recoil), Oedema (`O`), Induration (`In`).
    *   *Integrity*: Nil abnormalities, Fragile (`Fr`), Pressure injury (`PI`), Flake/scale (`FI`), Rash (`R`), Wound (`Wd`), Scarring (`S`), Callus (`Ca`), Cellulitis (`Ce`), Known disorder.
    *   *Colour*: Inspect for pallor, cyanosis, ecchymosis, jaundice, blanching, persistent redness, mottling, or purple/bluish tones across all skin complexions.
    *   *Altered Sensation*: Numbness/change (`N`), Burning (`B`), Itching (`It`), Pain (`P`).
    *   *Medical Devices in Situ*: Check locations of masks, endotracheal tubes (ETT), nasogastric tubes (NGT), tracheostomies, cervical collars, peripheral IV cannulae, CVC/PICC/Ports, PEG tubes, suprapubic catheters (SPC), indwelling catheters (IDC), drains, casts, splints, anti-embolic stockings.

PRESSURE INJURIES: PATHOPHYSIOLOGY, STAGING, AND RISK ASSESSMENT

• Pathophysiology and Epidemiology:

  • A pressure injury is localized damage to the skin and underlying soft tissue, usually over a bony prominence, resulting from intense or prolonged pressure combined with shear or friction.

  • Incidence: $9.7\text{ injuries per }10,000\text{ hospital stay episodes}$ (ACSQHC 2017).

• Hemodynamic Pressures and Microcirculation:

  • Interface Pressure: Pressure exerted between the skin surface and a support surface. Increasing contact surface area lowers interface pressure, whereas smaller contact points yield higher localized pressure.

  • Capillary Occlusion Threshold: Normal capillary perfusion pressure ranges from $32\,mmHg$ at the arteriolar end to $20\,mmHg$ mid-capillary and $12\,mmHg$ at the venular end. External pressure exceeding $32\,mmHg$ collapses microvascular capillaries, causing localized tissue ischemia, cellular hypoxia, metabolic waste accumulation, and necrosis.

• Anatomical High-Risk Pressure Points:

  • Supine/Lying Position: Occiput/head, scapulae/shoulders, elbows, sacrum/buttocks, heels, toes.

*   *Sitting Position*: Ischial tuberosities, sacrum, posterior thighs, calcaneus.

• Etiological Venn Factors:

*   *Extrinsic Factors*: Uniaxial pressure, friction, shear forces, impact injury, heat, ambient moisture, bad posture.
*   *Intrinsic Factors*: Immobility, sensory loss, advanced age, systemic disease, extremity body types, malnutrition, incontinence.

• Braden Scale Risk Assessment Tool (Form MR124):

*   Assesses six subscales scored from 1 to 4 (except Friction/Shear scored 1 to 3):
    1.  *Sensory Perception*: Ability to respond meaningfully to pressure discomfort (1 Completely Limited, 2 Very Limited, 3 Slightly Limited, 4 No Impairment).
    2.  *Moisture*: Degree of skin exposure to moisture (1 Constantly Moist, 2 Often Moist, 3 Occasionally Moist, 4 Rarely Moist).
    3.  *Activity*: Degree of physical activity (1 Bedfast, 2 Chairfast, 3 Walks Occasionally, 4 Walks Frequently).
    4.  *Mobility*: Ability to change and control body position (1 Completely Immobile, 2 Very Limited, 3 Slightly Limited, 4 No Limitations).
    5.  *Nutrition*: Usual food intake pattern (1 Very Poor, 2 Probably Inadequate, 3 Adequate, 4 Excellent).
    6.  *Friction and Shear*: Physical movement capacity without sliding (1 Problem, 2 Potential Problem, 3 No Apparent Problem).
*   **Risk Categorization Scores**:
    *   *High & Very High Risk*: Total Score $\{12\text{ or less}\}$ (or presence of any pressure injury).
    *   *Moderate Risk*: Total Score $13 - 14$.
    *   *At Risk*: Total Score $15 - 18$.
    *   *Minimal Risk*: Total Score $19 - 23$.
*   **Action Threshold**: A total Braden Score **$<18$** indicates patient is "At Risk" and requires immediate initiation of support surfaces, repositioning plans, and daily MR124B reassessments.

• Pressure Injury Staging Guide (NPUAP 2015):

  • Stage 1: Intact skin with a localized area of non-blanchable erythema. Presence of blanchable erythema, sensory, thermal, or firmness changes may precede visual changes. Does not include purple/maroon discoloration.

  • Stage 2: Partial-thickness skin loss with exposed dermis. Viable, pink/red, moist wound bed or intact/ruptured serum-filled blister. Adipose, granulation tissue, slough, and eschar are not visible. (Exclude MASD, IAD, MARSI, or traumatic tears).

  • Stage 3: Full-thickness skin loss. Adipose tissue is visible in the ulcer; granulation tissue and epibole (rolled edges) are often present. Slough/eschar may be visible. Undermining and tunneling may occur. Bone, tendon, muscle, fascia, and cartilage are not exposed.

  • Stage 4: Full-thickness skin and tissue loss with exposed or directly palpable fascia, muscle, tendon, ligament, cartilage, or bone. Slough/eschar may be visible. Epibole, undermining, and tunneling often present.

  • Unstageable: Full-thickness skin and tissue loss in which the extent of tissue damage cannot be confirmed because it is obscured by slough or eschar. If slough/eschar is removed, Stage 3 or 4 will be revealed. Stable, dry, adherent eschar on heels or ischemic limbs should not be removed.

  • Deep Tissue Pressure Injury (DTPI): Persistent non-blanchable deep red, maroon, or purple discoloration, or epidermal separation revealing a dark wound bed or blood-filled blister. Results from intense/prolonged pressure and shear forces at the bone-muscle interface.

SKIN TEARS: RISK FACTORS AND STAR CLASSIFICATION

• Definition and Risk Factors:

  • A skin tear is a traumatic injury resulting in the partial or complete separation of the outer skin layers (epidermis/dermis).

  • High-Risk Population: Elderly, dependent, or cognitively impaired patients.

  • Etiological Factors: Advanced age, fragile/dry skin, previous skin tears, systemic corticosteroid therapy, ecchymosis, poor nutrition/hydration, visual impairment, vascular comorbidities, and dependence on staff for transfers or ADLs.

• STAR Classification System:

*   **Category 1a**: Skin tear where edges can be realigned to normal anatomical position without undue stretching, and skin/flap colour is **not** pale, dusky, or darkened.
*   **Category 1b**: Skin tear where edges can be realigned to normal anatomical position without undue stretching, and skin/flap colour **is** pale, dusky, or darkened.
*   **Category 2a**: Skin tear where edges **cannot** be realigned to normal anatomical position, and skin/flap colour is **not** pale, dusky, or darkened.
*   **Category 2b**: Skin tear where edges **cannot** be realigned to normal anatomical position, and skin/flap colour **is** pale, dusky, or darkened.
*   **Category 3**: Skin tear where the skin flap is **completely absent**.

PRESSURE AREA CARE, PATIENT POSITIONING, AND MANUAL HANDLING

• Pressure Area Care Protocols:

  • Repositioning Frequency: Minimum 2-hourly rotational repositioning for immobile patients.

  • Sacral Pressure Reduction: For patients at high risk of pressure injuries, limit seated bed elevation above $30^\circ$ to a maximum of 2 hours to avoid shear forces on the sacrum.

  • Skin Hygiene & Emollients: Cleanse skin with pH-neutral agents, apply moisturizing emollients gently, apply moisture barrier creams to perineal zones, and never massage reddened bony prominences.

  • Heel Offloading: Ensure complete heel elevation off the bed mattress using specialized foam wedges or pillows.

• Standard Patient Anatomical Positions:

  • Semi-Fowlers: Head of bed elevated to $45^\circ$ supported by pillows; increases pressure on ischial and sacral regions.

  • Upright (High-Fowlers): Head elevated to $90^\circ$; maximum seated ischial loading.

  • Supine: Flat on back; relaxes abdominal muscles but restricts chest expansion.

  • Prone: Face down; relieves all pressure from posterior body surfaces.

  • Lateral: Side-lying at $30^\circ$ lateral tilt with limbs supported by foam wedges/pillows.

  • Semi-Prone (Sims'): Side-lying with upper leg flexed toward chest and lower arm behind body.

• Documentation Form MR120A (Pressure Area Prevention/Management Plan):

*   Mandatory documentation form utilized whenever a patient's Braden Score is **$<16$** or when an existing pressure ulcer is identified.

• Manual Handling and Ergonomics:

  • Manual Handling: Any activity requiring physical force to lift, lower, push, pull, carry, restrain, or move a person or object.

  • Hazardous Manual Tasks: Tasks involving high forces, awkward/sustained postures, repetitive motions, or vibration.

  • Three-Step Risk Management Process:

    1.  *Step 1 - Hazard Identification*: Identify tasks causing body stress.
    2.  *Step 2 - Risk Assessment*: Evaluate force, posture, duration, and environment.
    3.  *Step 3 - Risk Control*: Eliminate risks or implement engineering/mechanical controls (e.g., hoists, slide sheets, adjustable beds).
*   **Storage Guidelines**: Store heavier and frequently used items at waist level to prevent bending, stooping, or reaching.
*   **Musculoskeletal Disorders (MSDs)**: Direct or cumulative injuries including back strains, joint degeneration, disc herniation, carpal tunnel syndrome, and soft tissue tears.

ACTIVITIES OF DAILY LIVING (ADLs), HYGIENE, AND PHYSICAL COMFORT

• Definition of ADLs and Hygiene:

  • ADLs include fundamental daily self-care tasks: eating, drinking, rest/sleep, physical activity, personal hygiene, grooming, and elimination.

  • Hygiene preserves health, provides physical comfort, improves self-image, and maintains skin barrier defense.

  • Grooming comprises care of hair, nails, teeth, mouth, shaving, ears, eyes, and perineum.

• Lifespan Considerations:

  • Infants: Soft, highly sensitive skin with low infection resistance. Requires strict water temperature testing, non-irritating soaps, thorough genital cleaning, gentle drying in skin folds, and scalp washing to prevent cradle cap.

  • Adolescents: Increased apocrine sweat gland activity and hormonal changes; requires education on regular bathing, deodorants, and acne hygiene.

  • Older Adults: Epidermal thinning, dermal drying, reduced elasticity, decreased sebum/sweat production, and fragile capillaries. Frequent harsh soap usage causes severe cracking; full bathing is often reduced to alternate days with emollient washes.

• Physical Comfort and Sleep Promotion:

  • Factors Impeding Sleep: Environmental noise, bright lighting, physical pain, high/low room temperature, anxiety, incontinence, tight clothing, soiled/wrinkled bed linen, and caffeine intake.

  • Nursing Interventions: Maintain a quiet, temperature-regulated room; attend to hygiene and elimination prior to sleep; position in Semi-Fowlers with knees supported; administer prescribed analgesia; offer warm non-caffeinated drinks; lower bed height for safety; reduce environmental disruptions.

PERSONAL HYGIENE PROCEDURES: ORAL, EYE, AURAL, NASAL, NAIL, PERINEAL, AND HAIR CARE

• Eye Care and Special Eye Toilet:

  • Observe for inflammation, scleral jaundice, conjunctival pallor, purulent discharge, or pain.

  • Special Eye Toilet Protocol: Indicated for conjunctivitis, facial paralysis/ptosis, or unconscious state. Uses an aseptic technique with sterile $0.9\%$ normal saline and cotton swabs. Wipe strictly from inner to outer canthus using a new swab for each stroke. Always clean the unaffected eye first to prevent cross-contamination.

• Aural Care Guidelines:

  • Clean outer ear pinna during routine bathing. Never insert cotton-tipped applicators into the ear canal as this packs cerumen against the tympanic membrane.

  • Hearing Aid Care: Inspect for earwax accumulation, turn off when not in use, replace batteries regularly, store in a labeled dry case, and never expose to water.

  • Ear Drop Instillation: Instill ear drops warmed to room temperature; cold or hot solutions stimulate the inner ear semicircular canals, inducing severe vertigo, nystagmus, nausea, and vomiting.

• Nasal Care Protocol:

  • Encourage gentle nose blowing. If cleaning is required for encrusted secretions, gently insert a cotton-tipped applicator moistened with normal saline/water into the nostril, rotate, and discard. Apply water-soluble lubricant to nares to prevent soreness.

• Oral Hygiene and Special Mouth Care:

  • Complications of Poor Oral Care: Dental caries, periodontal disease, halitosis, painful stomatitis/ulcers, systemic infection, dulling of taste, and severe malnutrition.

  • Routine Oral Care: Brush teeth/tongue with soft toothbrush and fluoride toothpaste, floss interdentally, rinse with alcohol-free mouthwash.

  • Special Mouth Care (Mouth Toilet): Required for unconscious patients, strict NPO status, facial paralysis, or oral infection. Perform 2-4 hourly using foam swabs or cotton applicators dipped in saline or alcohol-free rinse. Apply water-soluble lip balm or Vaseline to lips.

• Nail Care Guidelines:

  • Clean under nails using a soft, blunt instrument.

  • Strict Clinical Restriction: Nurses MUST NOT cut or trim nails unless specifically trained. For patients living with diabetes mellitus, peripheral vascular disease, or peripheral neuropathy, nail care must be performed exclusively by a registered Podiatrist to prevent catastrophic nail bed trauma and infection.

• Perineal Care Protocol:

  • Female Patients: Always cleanse strictly from front to back (anterior to posterior) from vulva toward anus to prevent urinary tract contamination by fecal microorganisms.

  • Uncircumcised Male Patients: Gently retract the foreskin, cleanse the glans penis thoroughly, rinse, and immediately replace the foreskin to its natural anatomical position to prevent paraphimosis (strangulation of glans tissue).

  • Incontinence Management: Use pH-neutral cleanser, pat dry gently without friction, and apply a moisture barrier ointment.

• Hair Care Protocols:

  • Wash hair regularly to remove blood, sweat, sebum, and dead skin cells. Brush daily. Never cut a patient's hair without explicit written consent. Use individual combs per patient for infection control.

HUMAN NUTRITION AND MALNUTRITION SCREENING

• Essential Nutrients and Australian Guide to Healthy Eating:

  • The human body requires seven essential nutrient classes: Carbohydrates, Proteins, Lipids, Water, Fibre, Vitamins, and Mineral salts.

*   **Five Core Food Groups**:
    1.  *Grain (cereal) foods*
    2.  *Vegetables and legumes/beans*
    3.  *Fruit*
    4.  *Lean meats, poultry, fish, eggs, tofu, nuts, seeds, legumes*
    5.  *Milk, yoghurt, cheese and/or alternatives*

• Malnutrition Screening Procedure (MR111 and Form MR60.1.5):

  • Body Mass Index Formula: \tExt{BMI} = \frac{\text{Weight (kg)}}{(\text{Height (m)})^2}.

  • Waist Circumference Thresholds: High risk if $>88\text{ cm}$ in women or $>102\text{ cm}$ in men. Weight $>120\text{ kg}$ triggers the WACHS Heavier Patient Policy.

  • Malnutrition Screening Tool (MST) Scoring:

    • Unintentional Weight Loss: No = 0, Unsure = 2. If Yes: $1-5\text{ kg} = 1$, $6-10\text{ kg} = 2$, $11-15\text{ kg} = 3$, $>15\text{ kg} = 4$.

    • Decreased Appetite/Poor Intake: No = 0, Yes = 1.

  • Action Categories:

    • MST Score 0 - 1 (Low Risk): Record score in progress notes; rescreen weekly in acute settings or monthly in long-term care.

    • MST Score 2 (Moderate Risk): Record score, refer patient to Dietitian, commence Food Intake Chart (MR144C), weigh weekly, and rescreen weekly.

    • MST Score 3 - 5 (High Risk): Record score, urgent Dietitian referral, commence Food Intake Chart (MR144C), initiate High Protein High Energy (HPHE) diet, weigh weekly.

HYDRATION, FLUID BALANCE MANAGEMENT, AND OVER/UNDER-HYDRATION

• Total Body Water Metrics:

  • Total body water constitutes $80\%$ of mass in newborns, $60\%$ in adult males, and $55\%$ in adult females. Increased lean muscle mass correlates with higher water content.

• Fluid Loss Categories:

  • Sensible Losses (Measurable): Urine, liquid faeces, vomitus, gastric aspirate, wound drainage, blood.

  • Insensible Losses (Unmeasurable): Perspiration and respiratory evaporation, averaging approximately $800\,mL\text{ daily}$.

• Dehydration vs. Fluid Overload (Hypervolemia):

  • Dehydration: Low/concentrated urine output, sudden weight loss, excessive thirst, tachycardia, hypotension, weak peripheral pulses, poor skin turgor, dry mucous membranes, sunken eyes, headache, confusion.

  • Fluid Overload: Rapid weight gain, peripheral pitting oedema, jugular vein distension (JVD), elevated central venous pressure, hypertension, bounding pulse, tachypnoea, dyspnoea, orthopnoea, productive cough with pulmonary crackles.

• Fluid Balance Documentation (Form MR144):

*   **Medical Escalation Threshold**: Immediate medical review must be sought if urine output drops below **$< 0.5\,mL/kg/hr$**.
*   **Worked Case Analysis (Mrs Gladys Green, 94 kg)**:
    *   Patient fasting status. Output entries: 1000h vomitus $60\text{ mL}$, 1200h urine $100\text{ mL}$, 1330h urine $100\text{ mL}$ & vomitus $80\text{ mL}$, 1600h urine $50\text{ mL}$, 2030h bowel action. Total Oral/IV Input = $0\text{ mL}$. Total Output = $390\text{ mL}$ ($140\text{ mL}$ vomitus + $250\text{ mL}$ urine). Fluid Balance = **$-390\text{ mL}$ (Negative Balance)**.

DYSPHAGIA, SWALLOWING MECHANICS, AND TEXTURE-MODIFIED DIETS

• Definitions and Complications:

  • Dysphagia: Difficulty or impairment in swallowing.

  • Aspiration: Inadvertent misdirection of food, fluid, or saliva below the vocal cords into the respiratory tract (does not completely stop breathing).

  • Choking: Complete physical occlusion of the airway by a food bolus or foreign body preventing all ventilation.

  • Complications: Aspiration pneumonia, choking, severe dehydration, malnutrition, and weight loss.

• Three Physiology Phases of Swallowing:

1.  **Oral (Buccal) Phase (Voluntary)**: Food is masticated, lubricated with saliva, formed into a cohesive bolus, and pushed by the tongue posteriorly against the palate into the oropharynx.
2.  **Pharyngeal Phase (Involuntary)**: Bolus triggers pharyngeal sensory receptors. The soft palate elevates to close the nasopharynx, epiglottis folds downward over the laryngeal inlet, vocal cords adduct, breathing is temporarily inhibited, and pharyngeal constrictors force bolus into the oesophagus.
3.  **Oesophageal Phase (Involuntary)**: Peristaltic waves propel the food bolus down the length of the oesophagus past the relaxed lower oesophageal sphincter into the stomach.

• Feeding Protocols for Dysphagic Patients:

  • Position patient completely upright at $90^\circ$ (High-Fowlers) or seated in a chair; bed head must be elevated $>30^\circ$.

  • Instruct patient to tilt chin slightly downward (chin-tuck) when swallowing.

  • Serve small mouthfuls using a teaspoon; allow ample time; verify oral cavity is clear between bites (check for cheek pouching).

  • Safety Stop Rule: Cease feeding immediately if the patient coughs, chokes, drools, exhibits a wet/gurgly voice, develops dyspnoea, or demonstrates altered consciousness.

  • Keep patient upright for at least 20 minutes post-meal to prevent regurgitation and aspiration.

• Diet Modification Frameworks:

  • Australian Standards for Texture Modified Foods and Fluids:

    *   *Fluids*: Mildly Thick (Level 150), Moderately Thick (Level 400), Extremely Thick (Level 900).
    *   *Foods*: Texture A (Soft), Texture B (Minced & Moist), Texture C (Smooth Pureed).
*   **IDDSI Framework (International Dysphagia Diet Standardisation Initiative)**:

    *   *Level 0*: Thin Drinks
    *   *Level 1*: Slightly Thick Drinks
    *   *Level 2*: Mildly Thick Drinks
    *   *Level 3*: Moderately Thick Drinks / Liquidised Foods
    *   *Level 4*: Extremely Thick Drinks / Pureed Foods
    *   *Level 5*: Minced & Moist Foods ($4\text{ mm}$ lump size max for adults)
    *   *Level 6*: Soft & Bite-Sized Foods ($1.5 \times 1.5\text{ cm}$ piece size max for adults)
    *   *Level 7*: Easy to Chew / Regular Foods
