M02 - Comprehensive Nursing Study Guide: Health Assessment, Vital Signs, Communication, SBAR, Pain, and Hygiene Practices

Foundations of Health Assessment & Physical Examination Techniques

• Purposes of Health Assessment

  • Gathers baseline data regarding a patient's overall health status.

  • Supplements, confirms, or refutes subjective data obtained during the clinical interview.

  • Identifies and confirms nursing diagnoses.

  • Guides clinical decision-making regarding a patient's evolving health status and ongoing management.

  • Evaluates the clinical outcomes of provided care.

• Data Classification

  • Subjective Data: Information verbalized by the patient that cannot be independently measured or verified. Examples include descriptions of pain, nausea, dizziness, or statements such as "I feel cold."

  • Objective Data: Observable, measurable findings obtained through physical assessment, laboratory testing, or diagnostic equipment. Examples include a measured temperature of $100.4^\text{o}\text{F}$, active emesis, a blood pressure of $120/80\text{ mmHg}$, or visible diaphoresis.

  • Primary Data: Clinical information directly related to the current, presenting patient problem or chief complaint (e.g., abnormal vital signs or new focal symptoms).

  • Secondary Data: Contextual clinical data that is not immediately relevant to the primary acute issue (e.g., historical physical findings or normal system reviews). Secondary data is retained for comprehensive context but excluded from urgent clinical reporting to avoid distraction.

• Sequence of Physical Assessment Techniques

  • Physical examination requires the systematic application of four technical skills utilized through the senses of sight, smell, touch, and hearing.

  • Standard Physical Examination Order:

    1. Inspection: Visual and auditory scrutiny of the individual as a whole, progressing to each specific body system.

    2. Palpation: Touch assessment to evaluate physical characteristics.

    3. Percussion: Tapping body structures to evaluate tissue density and resonance.

    4. Auscultation: Listening to internal body sounds using a stethoscope.

  • Abdominal Assessment Exception: To avoid altering baseline bowel motility and bowel sounds through tactile manipulation, the order of abdominal assessment is modified to:

    1. Inspection

    2. Auscultation

    3. Percussion

    4. Palpation

• Detailed Examination Skills

  • Inspection:

    • Begins immediately upon initial contact with the patient during the general survey.

    • Requires adequate environmental lighting, complete exposure of the anatomical region being examined while maintaining patient modesty, and the targeted use of instruments (e.g., otoscope, ophthalmoscope, penlight, nasal speculum, vaginal specula).

  • Palpation:

    • Applies the sense of touch to assess texture, temperature, moisture, organ location and size, swelling, vibration, pulsation, crepitation, rigidity, spasticity, presence of masses, and localized tenderness or pain.

    • Nursing Constraint: Registered nurses perform light palpation only. Palpation must be slow, systematic, and gentle.

    *   *Hand Anatomical Specializations:* 
        *   *Fingertips:* Best for fine tactile discrimination (e.g., skin texture, localized swelling, arterial pulsations, and discrete lumps).
        *   *Fingers and Thumb (Grasping):* Optimal for detecting the position, shape, and consistency of an organ or mass.
        *   *Dorsa (Back) of Hands and Fingers:* Optimal for evaluating temperature due to thinner skin relative to the palmar surface.
        *   *Base of Fingers or Ulnar Surface of Hand:* Optimal for detecting vibrations.
*   **Auscultation:**
    *   Involves listening to vascular, respiratory, and gastrointestinal sounds produced by the body. Stethoscopes do not amplify sound; they isolate it by blocking extraneous ambient noise.
    *   *Stethoscope Component Functions:*
        *   *Diaphragm:* Flat edge; used to detect high-pitched sounds (e.g., normal heart sounds, breath sounds, bowel sounds).
        *   *Bell:* Deep, hollow cuplike shape; used to detect soft, low-pitched sounds (e.g., extra heart sounds, murmur, vascular bruits).

    *   *Basic Auscultation Principles:* Eliminate ambient environmental noise; maintain a warm room and warm the stethoscope chestpiece prior to application; avoid listening over dense body hair; **never** listen through a patient's gown or clothing; eliminate friction artifact caused by tubing contact.

• Infection Control & Safety Protocols

  • Standard precautions apply to every patient interaction regardless of diagnosed infection status.

  • Perform hand hygiene directly in front of the patient prior to physical contact.

  • Clean all assessment equipment (e.g., stethoscope head, blood pressure cuff) before and after patient contact.

  • Don appropriate Personal Protective Equipment (PPE) when isolation precautions are indicated.

  • Obtain explicit patient consent prior to initiating physical examination.

• Clinical Adaptation Across Special Populations

  • The Sick/Acutely Ill Patient: Prioritize essential assessments based on airway, breathing, and circulation (ABCs). Restructure the order to address high-priority body systems first. Limit position changes to conserve energy and request assistance to position patients who cannot move independently.

  • The Aging Adult:

    • Structure examination sequences to minimize position changes and prevent exhaustion.

    • Allow formal rest periods as necessary.

    • Utilize intentional, respectful physical touch to establish rapport and enhance communication, especially when visual or hearing acuity is impaired.

    • Never confuse age-related sensory deficits (hearing or vision loss) with cognitive impairment or confusion.

Vital Signs Physiology, Measurement, and Lifespan Variations

• Core Body Temperature Regulation

  • Physiological Mechanism: Cellular metabolism requires a stable core temperature averaging $37.2^\text{o}\text{C}\,(99^\text{o}\text{F})$. Thermal homeostasis is maintained via a negative feedback loop regulated by the hypothalamus in the brain, balancing metabolic heat production with environmental heat loss.

  • Influencing Physiological Variables:

    • Diurnal Cycle: Varies by $1^\text{o}\text{F}$ to $1.5^\text{o}\text{F}$, displaying a trough in early morning hours ($0:00$ to $6:00$) and a peak in late afternoon to early evening ($16:00$ to $18:00$).

    • Menstruation: Progesterone secretion during ovulation causes a peak rise in baseline temperature.

    • Exercise: Strenuous muscular activity increases metabolic heat production.

    • Age: Thermoregulation is less efficient in neonates and older adults.

  • Normal Reference Ranges:

    • Oral Temperature: Accurate and convenient; the sublingual site receives rich vascular supply from the carotid arteries, reflecting rapid core changes. Normal resting oral temperature is $37^\text{o}\text{C}\,(98.6^\text{o}\text{F})$, with an acceptable baseline range of $35.8^\text{o}\text{C}$ to $37.3^\text{o}\text{C}\,(96.4^\text{o}\text{F}\text{ to }99.1^\text{o}\text{F})$.

    • Rectal Temperature: Measures $0.4^\text{o}\text{C}$ to $0.5^\text{o}\text{C}\,(0.7^\text{o}\text{F}\text{ to }1^\text{o}\text{F})$ higher than oral readings.

    • Febrile Threshold: Oral or temporal reading of $≥ 38^\text{o}\text{C}\,(≥ 100.4^\text{o}\text{F})$.

• Pulse & Heart Rate Assessment

  • Physiological Mechanism: A palpable pressure wave generated through the peripheral arterial system by left ventricular contraction (stroke volume).

  • Normal Resting Adult Rate: $60\text{--}100\text{ beats per minute (bpm)}$.

  • Rate Terminology:

    • Bradycardia: Resting heart rate less than $60\text{ bpm}$.

    • Tachycardia: Resting heart rate greater than $100\text{ bpm}$.

  • Variations by Age & Sex: Heart rate is elevated in infants and children; after puberty, females exhibit a slightly faster baseline rate than males.

  • Heart Rhythm & Sinus Dysrhythmia:

    • Normal rhythm is regular. In children and young adults, sinus dysrhythmia is a benign irregularity where heart rate increases during the peak of inspiration (compensating for a transient drop in left ventricular stroke volume) and slows to baseline during expiration.

    • Nursing Protocol: If an irregular rhythm is detected, auscultate the apical pulse with a stethoscope for a full $60\text{ seconds}$.

  • Pulse Force Quantification Scale:

    • $+4$: Bounding (increased stroke volume; associated with exercise, severe anxiety, or fluid overload).

    • $+3$: Full, increased.

    • $+2$: Normal, expected.

    • $+1$: Weak, diminished, barely palpable (decreased stroke volume; associated with hemorrhagic shock or vascular occlusion).

    • $0$: Nonpalpable, absent.

  • Anatomical Assessment Sites: Temporal, Carotid, Apical, Brachial, Radial, Femoral, Popliteal, Posterior Tibial, and Dorsalis Pedis (Pedal) arteries.

• Respirations

  • Normal Physiology: In relaxed adults, breathing is regular, automatic, unlabored, and silent at a rate of $12\text{--}20\text{ breaths per minute}$.

  • Terminologies:

    • Bradypnea: Abnormally slow respiratory rate ($< 12\text{ breaths/min}$).

    • Tachypnea: Abnormally rapid respiratory rate ($> 20\text{ breaths/min}$).

  • Assessment Technique: Count respirations discreetly without informing the patient (e.g., maintain the hand on the radial pulse while counting chest rises for $30\text{ seconds}$ or a full $60\text{ seconds}$) to prevent conscious alteration of the respiratory pattern.

• Blood Pressure (BP)

  • Definitions:

    • Systolic Pressure: Maximum pressure exerted on the arterial wall during left ventricular systole.

    • Diastolic Pressure: Elastic recoil, or resting pressure exerted constantly between cardiac contractions.

    • Mean Arterial Pressure (MAP): The average pressure forcing blood into tissue beds across the full cardiac cycle.

  • UW-Madison School of Nursing Adult BP Classification Standards:

    • Normal: Systolic $< 120\text{ mmHg}$ AND Diastolic $< 80\text{ mmHg}$.

    • Elevated: Systolic $120\text{--}129\text{ mmHg}$ AND Diastolic $< 80\text{ mmHg}$.

    • Stage I Hypertension: Systolic $130\text{--}139\text{ mmHg}$ OR Diastolic $80\text{--}89\text{ mmHg}$.

    • Stage II Hypertension: Systolic $≥ 140\text{ mmHg}$ OR Diastolic $≥ 90\text{ mmHg}$.

  • Five Determinants of BP Level:

    1. Cardiac Output (CO): Increase in CO elevates BP; decrease in CO reduces BP.

    2. Peripheral Vascular Resistance: Vasoconstriction increases resistance and elevates BP; vasodilation decreases resistance and lowers BP.

    3. Volume of Circulating Blood: Fluid retention increases pressure; hemorrhage/dehydration decreases pressure.

    4. Viscosity: Thicker blood (higher hematocrit) increases resistance and elevates BP.

    5. Arterial Elasticity: Vessel rigidity (arteriosclerosis) increases resistance to systolic discharge, elevating BP.

  • Variables Influencing Blood Pressure Readings:

    • Age: BP increases progressively from childhood through older adulthood due to structural loss of vessel elasticity.

    • Sex: Post-pubertal females exhibit lower BP than age-matched males; post-menopausal females exhibit higher BP than males.

    • Race: Increased prevalence of hypertension in African American populations due to environmental and genetic factors.

    • Weight: Increased body mass correlates with elevated BP.

    • Exercise: Transiently elevates BP during activity; chronic conditioning lowers resting BP.

    • Emotions & Stress: Anxiety, pain, and fear trigger sympathetic activation, transiently raising BP.

    • Caffeine: Causes acute, temporary arterial vasoconstriction and elevated BP.

• Common Errors in Blood Pressure Measurement & Nursing Actions

• Oxygen Saturation ($ ext{SpO}_2$)

  • Mechanism: Transcutaneous pulse oximeter passes two wavelengths of light through a vascular bed (finger or earlobe) to measure the ratio of oxygenated hemoglobin ($ ext{HbO}_2$) to reduced (unoxygenated) hemoglobin ($ ext{Hb}$).

  • Normal Values: Healthy resting range is $97\text{\%}\text{--}98\text{\%}$ (clinical target ranges accept $94\text{\%}\text{--}100\text{\%}$).

• Lifespan & Developmental Variations

  • Infants & Children:

    • Order of assessment in infants: Measure respirations first, followed by pulse, and temperature last to minimize crying-induced alterations.

    • Blood pressure is not routinely evaluated in asymptomatic children younger than $3\text{ years}$.

    • Avoid rectal temperatures when possible; utilize tympanic, axillary, or temporal routes.

    • Preschool children often fear body mutilation; demonstrate equipment on dolls or allow them to touch non-invasive tools.

  • Aging Adults:

    • Temperature: Thermoregulatory mechanisms decline, blunting fever response during active infection and increasing hypothermia risk. Reduced sweat gland activity.

    • Pulse: Normal range remains $60\text{--}100\text{ bpm}$. Arteries become stiff, rigid, and tortuous, requiring a faster systolic upstroke.

    • Respirations: Reduced vital capacity and decreased inspiratory reserve volume lead to shallower inspirations and a slightly increased resting rate.

    • Blood Pressure: Arterial wall hardening elevates systolic pressure while diastolic pressure remains stable or drops, widening the pulse pressure.

Comprehensive Pain Assessment

• Foundational Concepts

  • Pain is an entirely subjective finding and is defined as the fifth vital sign.

  • It is categorized by duration, physiological mechanism, and anatomical location.

• Classification by Duration

• Anatomical Sources of Pain

  • Visceral Pain: Originates from large internal organs (e.g., stomach, intestines, gallbladder, pancreas). Caused by direct organ injury or distention/stretching from tumors, ischemia, or severe muscular contraction. Accompanied by autonomic responses including nausea, vomiting, pallor, and diaphoresis.

  • Deep Somatic Pain: Originates from blood vessels, joints, tendons, muscles, and bones. Caused by trauma, pressure, or ischemia. Described as aching or throbbing, well-localized, and may present with secondary autonomic responses (tachycardia, hypertension).

  • Cutaneous Pain: Derived from skin surface and subcutaneous tissues. Superficial injury produces a sharp, burning sensation.

  • Referred Pain: Pain originates at a specific visceral or somatic site but is felt at a distant anatomical location. Occurs because both sites share embryonic origin and innervation by the same spinal nerve segment, making central interpretation difficult for the brain.

• Pain Assessment Frameworks

  • OLD CARTS: Onset, Location, Duration, Characteristics, Aggravating factors, Relieving factors, Treatments tried, Severity ($1\text{--}10$ scale).

  • PQRSTU:

    • P = Provocative / Palliative (What brings it on? What makes it better or worse?)

    • Q = Quality / Quantity (How does it feel? Burning, aching, sharp?)

    • R = Region / Radiation (Where is it? Does it spread?)

    • S = Severity Scale (Rating from $0$ to $10$)

    • T = Timing (Onset, frequency, duration)

    • U = Understanding (What does the patient think is causing it?)

  • Numeric Rating Scale (NRS):

    • $0$: No Pain

    • $1\text{--}3$: Mild Pain

    • $4\text{--}6$: Moderate Pain

    • $7\text{--}9$: Severe Pain

    • $10$: Very Severe / Worst Pain Possible

• Special Population Behavioral Pain Scales

  • Neonatal Infant Pain Scale (NIPS): Evaluates facial expression ($0\text{--}1$), cry ($0\text{--}2$), breathing patterns ($0\text{--}1$), arms ($0\text{--}1$), legs ($0\text{--}1$), and state of arousal ($0\text{--}1$).

  • FLACC Scale: Validated for pediatric patients ($2\text{ months}$ to $7\text{ years}$) or individuals with cognitive/developmental impairment. Evaluates five categories scored from $0$ to $2$ (Total score $0\text{--}10$):

    1. Face: $0$ = relaxed/smile; $1$ = occasional grimace/frown; $2$ = frequent/constant frown, clenched jaw, quivering chin.

    2. Legs: $0$ = normal/relaxed; $1$ = uneasy, restless, tense; $2$ = kicking or legs drawn up.

    3. Activity: $0$ = lying quietly, moves easily; $1$ = squirming, shifting, tense; $2$ = arched, rigid, or jerking.

    4. Cry: $0$ = no cry; $1$ = moans/whimpers, occasional complaint; $2$ = crying steadily, screams, frequent complaints.

    5. Consolability: $0$ = content, relaxed; $1$ = reassured by touch/talking, distractible; $2$ = difficult to console.

*   **PAINAD (Pain Assessment in Advanced Dementia) Scale:** Designed for non-verbal patients with advanced dementia. Evaluates 5 items on a $0\text{--}2$ scale:
    *   *Breathing:* $0$ = Normal; $1$ = Occasional labored breathing/short hyperventilation; $2$ = Noisy labored breathing, long hyperventilation, Cheyne-Stokes respirations.
    *   *Negative Vocalization:* $0$ = None; $1$ = Occasional moan/groan, low volume disapproving speech; $2$ = Repeated troubled calling out, loud moaning/crying.
    *   *Facial Expression:* $0$ = Smiling or inexpressive; $1$ = Sad, frightened, frown; $2$ = Facial grimacing.
    *   *Body Language:* $0$ = Relaxed; $1$ = Tense, distressed pacing, fidgeting; $2$ = Rigid, fists clenched, knees pulled up, striking out.
    *   *Consolability:* $0$ = No need to console; $1$ = Distracted or reassured by voice/touch; $2$ = Unable to console, distract, or reassure.

Interprofessional & Nurse-Patient Communication

• The Therapeutic Nurse-Patient Relationship

  • A person-centered, dynamic, purposeful, and time-limited interaction.

  • The nurse is professionally accountable for outcomes; goals are established cooperatively based on patient needs.

  • Requires clear boundaries, active listening, and respect for privacy.

• Forms of Communication

  • Verbal: Spoken or written words reliant on shared language and comprehension.

  • Non-Verbal: Facial expressions, gestures, eye contact, touch, posture, spatial boundaries, gait, grooming, and vocalizations (moaning, crying, sighing).

  • Intrapersonal Communication: Self-talk or internal cognitive reflection.

  • Interpersonal Communication: Direct interaction between two or more people.

• Factors Influencing Communication

  • Developmental level, sociocultural context, professional roles, physical/mental/emotional state, spatial territoriality, environmental noise, and personal values.

• Interviewing Traps to Avoid (10 Non-Therapeutic Traps)

  1. Providing False Reassurance: Discounts patient feelings and closes communication.

  2. Giving Unwanted Advice: Shifts decision-making away from patient autonomy.

  3. Using Authority: Implying the nurse knows best ("Doctor knows best").

  4. Using Avoidance Language: Euphemisms like "passed on" instead of clear statements.

  5. Using Professional Jargon: Medical terminology that confuses non-clinicians.

  6. Using Distancing Language: Depersonalizing body parts (e.g., "the left breast" vs. "your left breast").

  7. Using Leading or Biased Questions: Framing questions to prompt a specific answer.

  8. Talking Too Much: Overwhelming the patient with excessive nurse speech.

  9. Interrupting: Breaking patient train of thought before completion.

  10. Using "Why" Questions: Implies accusation and triggers defensiveness.

• Communication Enhancement Strategies

  • Active Listening: Maintain eye contact, adopt an open posture, sit down at eye level with the patient, avoid interrupting, and observe non-verbal cues.

  • W.A.I.T. Principle: Short for "Why Am I Talking?" Reminds clinicians to practice intentional silence and reflective listening.

  • Teach-Back Method: Asking patients to restate instructions in their own words to verify comprehension.

  • Communication with Impaired Patients (e.g., Post-CVA Expressive Aphasia): Expressive aphasia impairs speech production while comprehension remains intact. Utilize communication/picture boards, ask simple one-at-a-time questions requiring gestures, maintain patience, eliminate distractions, and avoid raising voice volume.

Team Communication, Safety Escalation, and SBAR

• Interprofessional Communication Barriers

  • Root-cause analysis by The Joint Commission indicates that $60\text{\%}\text{--}70\text{\%}$ of all sentinel events stem directly from communication failures between healthcare providers.

  • Historical Hierarchy: Traditional power dynamics where physicians made unchallenged decisions hinder safety.

  • Differing Educational Styles: Nurses are educated to communicate using chronologically detailed narrative structures, whereas physicians are trained to synthesize concise, prioritized bullet points.

  • Psychologically Unsafe Interactions: Fear of anger, condescension, or dismissal prevents nurses from reporting early subtle changes.

• SBAR History & Evolution

  • Origins: Adapted from the nuclear submarine Situational Briefing Model and aeronautic industry checklists.

  • Healthcare Integration: Developed in 2002 by quality expert David Bonacum at Kaiser Permanente to standardize critical communication in high-risk areas (ICU, OR, Obstetrics) before expanding system-wide.

• The Four Steps of SBAR

1.  **Situation (S):** State identity, clinical unit, patient name, and the immediate presenting issue ($10\text{ seconds}$ target).
2.  **Background (B):** Provide relevant clinical context, admitting diagnosis, pertinent past medical history, current medications, allergies, and advance directives ($20\text{ seconds}$ target).
3.  **Assessment (A):** Report current objective/subjective findings, abnormal vital signs, focused physical findings, symptom analysis, and a clear clinical synthesis statement ($20\text{ seconds}$ target).
4.  **Recommendation (R):** Explicitly request specific actions, state the urgency time frame, and propose immediate interventions ($10\text{ seconds}$ target).
*   *Target Duration:* Concise report delivered in under $1\text{ minute}$.

• Pre-Report Preparation Checklist

  • Step 1: Patient Assessment: Complete vital signs and focused physical assessment. Conduct detailed symptom analysis (Location, Quality, Severity $0\text{--}10$, Timing, Aggravating/Relieving factors).

  • Step 2: Urgency Determination:

    • Emergent: Requires physician action within $1\text{--}2\text{ hours}$ (or immediate $911$/rapid response).

    • Urgent: Requires action within $6\text{--}12\text{ hours}$.

    • Routine: Managed during standard office hours.

  • Step 3: Medical Record Review: Have chart open to vital sign trends, lab results, medication administration record (MAR), and pharmacy contact info.

  • Step 4: Information Synthesis: Filter data into primary (essential abnormal findings) and secondary data (retained in mind for questions).

• Clinical SBAR Template (COPD Exacerbation Example)

  • Situation: "Dr. Jones, this is Nurse Mary from Best Home Health. I am calling regarding Mr. Smith who is experiencing acute, increased dyspnea."

  • Background: "Mr. Smith is a $72\text{-year-old}$ male with Stage III COPD and heart failure. He was discharged $5\text{ days}$ ago post-COPD exacerbation. He is on continuous oxygen at $2\text{ L/min}$ via nasal cannula and uses daily maintenance inhalers. Full medication list and pharmacy numbers are available."

  • Assessment: "SpO2 is $88\text{\%}$ on $2\text{ L}$, respiratory rate is $28$, HR is $104$, BP is $138/84$, and temperature is $100.2^\text{o}\text{F}$ orally. Auscultation reveals coarse crackles and bilateral wheezing in lower lobes. Cough is productive of thick gray-green sputum. He exhibits pursed-lip breathing. I believe he is developing an acute lower respiratory tract infection triggering a COPD exacerbation."

  • Recommendation: "I recommend initiating an oral antibiotic and a $10\text{-day}$ course of oral prednisolone ($30\text{--}40\text{ mg}$ daily), along with converting his short-acting bronchodilators to nebulizer delivery every $4\text{ hours}$. I will repeat back any orders now."

• Safety Escalation Protocol: The CUS Tool

  • Utilized when team members do not respond to SBAR recommendations or when patient safety is compromised.

  • C: "I am Concerned…"

  • U: "I am Uncomfortable…"

  • S: "This is a Safety issue / Patient safety is at risk…"

Hygiene, Activities of Daily Living (ADLs), and Clinical Care Protocols

• Purposes of Hygiene Care

  • Promotes bodily comfort, removes microorganisms to prevent infection, stimulates cutaneous circulation, preserves skin integrity, and enhances self-esteem.

• Factors Influencing Hygiene Needs

  • Physical illness/pain/fatigue, developmental stage, cultural grooming norms, socioeconomic access to supplies, and individual preferences.

• Perineal Care Protocols

  • Female Cleansing Procedure:

    • Position in dorsal recumbent.

    • Always clean from front to back (urethra toward rectum) to prevent fecal contamination of the urinary tract.

    • Order: Labia majora $→$ Labia minora $→$ Urethral meatus $→$ Vaginal orifice $→$ Perineal/Anal area.

    • Use a separate, clean section of the washcloth for every single downward wipe.

  • Male Cleansing Procedure (Uncircumcised):

    • Gently retract the foreskin (prepuce).

    • Clean the meatus and glans penis using a circular motion starting at the urethral orifice and moving outward.

    • Clean the penile shaft and scrotum.

    • Critical Safety Rule: Immediately return the foreskin to its natural anatomical position over the glans to prevent paraphimosis (tissue ischemia and edema).

• Oral & Denture Care

  • High-Risk Populations: Patients receiving oxygen therapy, NPO status, fluid restriction, or unconscious states.

  • Unconscious Patient Care: Priority is aspiration prevention. Position patient in a side-lying (lateral) posture with head turned toward the mattress. Have working suction equipment immediately available.

  • Denture Care: Handle with care; clean over a basin lined with a towel using cool or lukewarm water (hot water warps denture plastic). Store in a labeled, fluid-filled denture cup. Never wrap dentures in paper towels or tissue.

• Indwelling Urinary Catheter Maintenance & CAUTI Prevention

  • Perform daily perineal hygiene and catheter care.

  • Clean catheter tubing starting at the urethral meatus and moving outward/downward (away from the body) using mild soap and water.

  • Secure catheter to the thigh to prevent traction and urethral trauma.

  • Maintain a completely closed drainage system.

  • Keep the drainage bag positioned below the level of the bladder at all times to prevent retrograding urine flow. Never place the bag directly on the floor.

  • Ensure tubing remains free of kinks, twisting, or dependent loops.

• Elimination Devices Application Guide

  • Standard/Fracture Bedpan: Used for fecal elimination or female urination in non-ambulatory patients confined to bed.

  • Urinal: Used for male voiding in bed.

  • PureWick System: External female transvulval suction catheter used for non-invasive urinary management in bedbound women.

  • PrimaFit / Condom Catheter: External male penile sheath catheter used for non-invasive urinary collection in bedbound men.

• Bed Safety & Occupied Bed Making Principles

  • Maintain bed in the lowest height setting when care is not actively being provided.

  • Verify bed frame wheels are locked at all times.

  • Keep call light within direct patient reach.

  • Raise bed to a comfortable working height for the caregiver during bed changes to maintain proper body mechanics; return to lowest position upon completion.

  • Ensure linens are tight and wrinkle-free to prevent mechanical shear and pressure injury development.

Medical Mathematics & Dosage Calculation Foundations

• Standard Time Notation

  • Express clinical time using military 24-hour clock formatting (e.g., $04:36$, $09:36$, $16:00$, $23:59$).

• Decimal Expressive Rules

  • Leading Zeros: ALWAYS place a leading zero before a decimal point when the numerical value is less than 1 (e.g., write $0.125\text{ mg}$, $0.15\text{ mL}$).

  • Trailing Zeros: NEVER include trailing zeros after a decimal point because ink obliteration leads to ten-fold overdose errors (e.g., write $0.15$ NOT $0.150$; write $17\text{ mg}$ NOT $17.0\text{ mg}$).

• Key Clinical Equivalencies & Conversions

  • $1\text{ fluid ounce (oz)} = 30\text{ milliliters (mL)}$

  • $1\text{ kilogram (kg)} = 2.2\text{ pounds (lbs)}$

  • $1\text{ gram (g)} = 1,000\text{ milligrams (mg)}$

  • $1\text{ milligram (mg)} = 1,000\text{ micrograms (mcg)}$

  • $1\text{ Liter (L)} = 1,000\text{ milliliters (mL)}$

• Worked Calculation Examples

  • Microgram Conversion: $17\text{ mg} = 17 \times 1,000\text{ mcg} = 17,000\text{ mcg}$

  • Volume Conversion: $106\text{ mL} = \frac{106}{1,000}\text{ L} = 0.106\text{ L}$

  • Weight Conversion: Patient weighing $110\text{ lbs} = \frac{110}{2.2}\text{ kg} = 50\text{ kg}$
