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

Factors Influencing Communication

Variables that affect interpersonal interactions, including developmental level, sociocultural context, professional roles and responsibilities, spatial territoriality, physical/mental/emotional state, personal values, and environmental factors.

Forms of Nonverbal Communication

Transmission of information without spoken words, encompassing facial expressions, gestures, eye contact, touch, posture, spatial boundaries, gait, general grooming, and vocalizations such as moaning or sighing.

Therapeutic Nurse-Patient Relationship

A person-centered, dynamic, purposeful, and time-limited interaction where the nurse is professionally accountable for outcomes and goals are cooperatively established based on patient needs.

Communication Interventions for Expressive Aphasia

Strategies used when speech production is impaired but comprehension remains intact (e.g., post-CVA), including using communication or picture boards, asking simple one-at-a-time questions requiring gestures, eliminating environmental noise, and maintaining patience without shouting.

SBAR Communication Framework

A standardized four-step communication tool consisting of Situation (identity and immediate problem), Background (relevant medical context and history), Assessment (pertinent subjective and objective findings), and Recommendation (explicit requested action and urgency timeframe).

Purposes of Health Assessment

Clinical data collection used to gather baseline health data, supplement or confirm subjective interview findings, identify and confirm nursing diagnoses, guide ongoing clinical management, and evaluate care outcomes.

Subjective vs. Objective Data

Subjective data consists of unverified information verbalized by the patient (e.g., pain, nausea, feeling cold). Objective data consists of observable, measurable findings obtained through physical exam, lab tests, or diagnostic tools (e.g., temperature of $100.4^\text{o}\text{F}$, blood pressure of $120/80\text{ mmHg}$).

Sequence of Assessment Techniques

The standard physical examination order: 1. Inspection, 2. Palpation, 3. Percussion, 4. Auscultation. Note: For abdominal assessments, the sequence is modified to Inspection, Auscultation, Percussion, Palpation to avoid altering bowel motility.

Core Body Temperature Physiology

Homeostatic temperature balance regulated by the hypothalamus via a negative feedback loop that balances heat production and loss to maintain an average core body temperature of $37.2^\text{o}\text{C}\text{ (}99^\text{o}\text{F}\text{)}$.

Normal Adult Vital Sign Reference Ranges

Oral Temperature: $35.8\text{--}37.3^\text{o}\text{C}\text{ (}96.4\text{--}99.1^\text{o}\text{F}\text{)}$; Resting Heart Rate: $60\text{--}100\text{ bpm}$; Respiratory Rate: $12\text{--}20\text{ breaths/min}$; Blood Pressure: Systolic $< 120\text{ mmHg}$ and Diastolic $< 80\text{ mmHg}$; Oxygen Saturation ($\text{SpO}_2$): $$97 ext{ ext{ ext

Communication Process & Influencing Factors

The communication process involves a sender transmitting a message through a channel to a receiver, who provides feedback. Factors influencing it include developmental level, sociocultural context, gender, professional roles, spatial territoriality, physical/mental/emotional state, personal values, and environment.

Nonverbal Communication Methods

Communication expressed without words, including facial expressions, eye contact, gestures, posture, gait, body movement, spatial distance, touch, general physical appearance/grooming, and non-language vocal sounds (e.g., moaning, crying, gasping, sighing).

Interrelation of Communication & Nursing Process

Communication is essential at every stage of the nursing process: gathering subjective data (Assessment), identifying patient problems (Diagnosis), co-creating goals (Outcome Identification/Planning), implementing nursing actions and patient teaching (Implementation), and evaluating goal achievement through feedback (Evaluation).

Cultural Competence in Communication

Involves avoiding assumptions, asking patients about their cultural health beliefs and preferences, using professional medical interpreters rather than family members, and adapting communication techniques to respect cultural norms regarding eye contact, touch, and personal space.

Ineffective Communication Traps

Non-therapeutic behaviors—such as providing false reassurance, giving unwanted advice, using authority, using professional jargon, using avoidance or distancing language, asking leading or "why" questions, interrupting, or talking too much—erodes trust and hinders the therapeutic relationship.

Therapeutic Nurse-Patient Relationship

A person-centered, dynamic, purposeful, and time-limited interaction where the nurse is professionally accountable for outcomes and goals are cooperatively established based on patient needs. Key techniques include active listening, sitting at eye level, showing empathy, and maintaining professional boundaries.

Interventions for Impaired Communication

For patients with conditions like expressive aphasia or cognitive deficits, interventions include using simple one-at-a-time questions requiring gestures, utilizing communication/picture boards, allowing ample response time, eliminating ambient noise, speaking clearly without shouting, and using qualified interpreters when language barriers exist.

SBAR Framework Components

A standardized structured communication tool: Situation (identity, patient, immediate problem in $10\text{ seconds}$), Background (clinical context, diagnosis, history in $20\text{ seconds}$), Assessment (vital signs, physical findings, analysis in $20\text{ seconds}$), and Recommendation (explicit requested action in $10\text{ seconds}$).

Professional Nurse Role in Health Assessment

Collecting comprehensive baseline data, distinguishing normal from abnormal physical and psychosocial findings, recognizing clinical changes, analyzing data to formulate nursing diagnoses, and evaluating patient responses to care.

Purposes of Health Assessment

Gathers baseline health data, confirms or refutes subjective data, identifies actual or potential nursing diagnoses, guides clinical decision-making regarding changing health status, and evaluates the clinical outcomes of provided care.

Types & Frequencies of Health Assessments

Includes initial/comprehensive assessments (broad baseline data upon admission), focused assessments (targeted to specific body systems or acute problems), emergency assessments (rapid evaluation of life-threatening ABCs), and ongoing/shift assessments (monitored at scheduled clinical intervals or upon patient change).

Comprehensive Health Assessment Components

Consists of two main parts: a complete health history (subjective data including chief complaint, history of present illness, past medical history, family history, and review of systems) and a full physical examination (objective physical assessment findings).

Organizing Frameworks for Assessment Data

Structured models used to collect and organize assessment data, such as Gordon's Functional Health Patterns, Body Systems Framework (e.g., cardiovascular, respiratory), or Head-to-Toe physical examination framework.

Subjective vs. Objective Data

Subjective Data consists of information verbalized by the patient that cannot be independently measured (e.g., pain scale rating, nausea, dizziness). Objective Data consists of observable, measurable findings obtained through exam, labs, or diagnostic equipment (e.g., blood pressure $120/80\text{ mmHg}$, temperature $100.4^\text{o}\text{F}$, active emesis).

Physiological Regulation of Vital Signs

Temperature is regulated by the hypothalamus via feedback loops; Pulse is generated by left ventricular stroke volume creating a peripheral pressure wave; Respirations are driven by brainstem chemoreceptors responding to arterial $CO_2$ and $pH$ levels; Blood pressure is determined by cardiac output, peripheral vascular resistance, blood volume, blood viscosity, and arterial elasticity.

Factors Influencing Vital Signs

Fever, physical exercise, stress/anxiety, and pain increase temperature, heart rate, respirations, and blood pressure. Hemorrhage or dehydration decreases blood pressure while increasing heart rate and respirations. Conditioning, rest, hypothermia, and vagal stimulation decrease heart rate and metabolic rate.

Anatomical Assessment Sites for Vital Signs

Temperature: Oral (sublingual), tympanic, temporal artery, axillary, rectal. Pulse: Radial, carotid, brachial, femoral, popliteal, posterior tibial, dorsalis pedis, and apical (5th intercostal space, midclavicular line). Blood Pressure: Brachial artery (arm) or popliteal artery (thigh).

Standard Assessment Techniques for Vital Signs

Measure oral temp sublingually; count radial pulse for $30\text{ seconds}$ (or $60\text{ seconds}$ if irregular); count respirations discreetly for $30\text{--}60\text{ seconds}$; select a BP cuff width equal to $40\text{\%}$ of arm circumference, support arm at heart level, and deflate cuff at $2\text{--}3\text{ mmHg/second}$.

Normal Adult Vital Sign Reference Ranges

Oral Temperature: $35.8^\text{o}\text{C}\text{--}37.3^\text{o}\text{C}\,(96.4^\text{o}\text{F}\text{--}99.1^\text{o}\text{F})$. Heart Rate: $60\text{--}100\text{ bpm}$ (infants $100\text{--}160\text{ bpm}$). Respirations: $12\text{--}20\text{ breaths/min}$ (infants $30\text{--}60\text{ breaths/min}$). Blood Pressure: Systolic $< 120\text{ mmHg}$ AND Diastolic $< 80\text{ mmHg}$.

Subjective Pain Assessment Frameworks

Data collected using structured tools like OLD CARTS or PQRSTU (Provocative/Palliative, Quality, Region/Radiation, Severity $0\text{--}10$, Timing, Understanding). Descriptors include sharp, burning, aching, throbbing, dull, or shooting pain.

Objective Indicators of Pain

Observable findings including behavioral cues (facial grimacing, frowning, crying, moaning, restlessness, guarding, rigid posture) and physiological autonomic responses (tachycardia, elevated blood pressure, tachypnea, diaphoresis).

Behavioral Pain Scales (FLACC & PAINAD)

FLACC Scale evaluates Face, Legs, Activity, Cry, Consolability ($0\text{--}10$ total) for non-verbal pediatric or cognitively impaired patients. PAINAD Scale evaluates Breathing, Negative Vocalization, Facial Expression, Body Language, Consolability ($0\text{--}10$ total) for non-verbal patients with advanced dementia.
