Conducting Nursing Assessments

Why This Skill Exists

Comprehensive nursing assessment is the foundation of the nursing process defined in the ANA Scope and Standards of Practice (Standard 1: Assessment). Missed or incomplete assessments are the leading contributor to failure-to-rescue events. This skill structures a systematic head-to-toe evaluation that aligns with Joint Commission NPSG requirements, CMS Conditions of Participation for patient assessment (§482.13), and institutional documentation standards. It ensures that every body system is evaluated, abnormal findings are escalated appropriately, and the assessment narrative is defensible in medical-legal review.

Checkpoint A — Intake Verification

Before beginning the assessment, confirm the following inputs are available and complete:

Required Patient Information

[ ] Patient identity verified using two identifiers (Joint Commission NPSG.01.01.01)
[ ] Admitting or working medical diagnosis
[ ] Current medication list including time of last dose
[ ] Relevant surgical or procedural history
[ ] Known allergies with reaction type (anaphylaxis vs. intolerance vs. sensitivity)
[ ] Code status and advance directive availability
[ ] Primary language and interpreter needs

Required Source Documents

[ ] Most recent prior nursing assessment (for comparison trending)
[ ] Active physician/APP orders
[ ] Current vital signs (within preceding 4 hours or per unit protocol)
[ ] Relevant laboratory results (BMP, CBC, coagulation studies, lactate as applicable)
[ ] Imaging results if pertinent to current condition
[ ] Pain assessment score from most recent evaluation

Scope Determination

Determine if this is an admission assessment, shift assessment, focused reassessment, or transfer assessment
Identify unit-specific required assessment components (e.g., neuro checks q1h for stroke unit, circulatory checks for post-catheterization)
Confirm documentation system and required flowsheet fields

Step 1 — General Survey and Vital Signs Baseline

Perform the general survey before touching the patient:

Observe level of consciousness using the Glasgow Coma Scale (Eye 1–4, Verbal 1–5, Motor 1–6; total 3–15)
Assess general appearance: nutritional status, hygiene, affect, posture, gait if ambulatory
Record a complete set of vital signs: temperature (route), heart rate, respiratory rate, blood pressure (position and extremity), SpO2 (on room air or specify FiO2), pain score
Calculate the Modified Early Warning Score (MEWS) or unit-specific early warning score
Compare current vitals against the patient's baseline trend (not just reference ranges)
Flag any MEWS ≥ 4 or single-parameter critical value for immediate escalation per rapid response criteria

Document deviations from expected baseline. A blood pressure of 100/60 may be normal for a young athletic patient but critical for a patient whose baseline runs 160/90.

Step 2 — Neurological Assessment

Orientation — assess to person, place, time, and situation (A&Ox4)
Pupil response — size in millimeters, shape (round, ovoid, irregular), reactivity (brisk, sluggish, fixed), consensual response; compare bilaterally
Motor function — grip strength bilateral, dorsiflexion/plantar flexion bilateral; use 0–5 muscle strength scale
Sensory — light touch and sharp/dull discrimination in all extremities if indicated
Cranial nerves — facial symmetry (CN VII), gag reflex (CN IX/X), tongue midline (CN XII) as appropriate to diagnosis
Fall risk — complete the Morse Fall Scale or unit-specific fall risk tool; score ≥ 45 = high risk requiring fall prevention interventions

Document any change from previous assessment. New-onset unilateral weakness, pupil asymmetry > 1 mm, or sudden change in LOC requires immediate provider notification.

Step 3 — Cardiovascular Assessment

Auscultate heart sounds in aortic, pulmonic, Erb's point, tricuspid, and mitral areas
Identify rhythm (regular vs. irregular), rate, and any murmurs (grade I–VI), gallops (S3/S4), or rubs
Assess peripheral pulses: radial, dorsalis pedis, posterior tibial — rate 0 (absent) to 3+ (bounding)
Evaluate capillary refill (normal < 3 seconds)
Inspect for edema: location, pitting scale (1+ to 4+), and symmetry
Check JVD with head of bed at 45 degrees
Review telemetry rhythm if monitored (reference managing-telemetry-monitoring skill)

Report new murmurs, absent pulses, capillary refill > 3 seconds, or 3+ pitting edema immediately.

Step 4 — Respiratory Assessment

Observe respiratory effort: use of accessory muscles, nasal flaring, retractions, tripod positioning
Auscultate all lung fields bilaterally: anterior (6 sites) and posterior (6 sites)
Document breath sounds: clear, diminished, crackles (fine/coarse), wheezes (inspiratory/expiratory), rhonchi, stridor, absent
Record oxygen delivery method and flow rate or FiO2
Note cough characteristics: productive (describe sputum color, consistency, amount) or nonproductive
Calculate SpO2/FiO2 ratio if concern for acute respiratory distress (ratio < 315 suggests ALI, < 200 suggests ARDS)

New-onset stridor, SpO2 < 90% on supplemental O2, or acute respiratory distress requires immediate escalation.

Step 5 — Gastrointestinal Assessment

Auscultate bowel sounds in all four quadrants before palpation (normoactive, hypoactive, hyperactive, absent)
Inspect abdomen: contour (flat, rounded, distended, protuberant), surgical scars, ostomy presence
Palpate lightly for tenderness, guarding, rigidity, rebound
Document last bowel movement, stool characteristics (Bristol Stool Scale 1–7), and any emesis
Assess nutritional intake: percentage of meals consumed, enteral/parenteral nutrition tolerance
Evaluate tube placement verification if NG/OG/PEG present (pH testing, external length marking)

Rigid abdomen, absent bowel sounds with distension, or new-onset bloody emesis requires immediate provider notification.

Step 6 — Genitourinary Assessment

Document urine output: amount, color, clarity, odor
Calculate urine output per kg/hr if critically ill (target ≥ 0.5 mL/kg/hr)
Assess Foley catheter if present: insertion date, securement, drainage tubing patency, daily necessity review per CAUTI bundle
Evaluate for urinary retention via bladder scan if indicated (> 300 mL post-void residual is significant)
Note continence status and any skin breakdown risk from moisture

Step 7 — Musculoskeletal and Integumentary Assessment

Perform Braden Scale assessment (sensory perception, moisture, activity, mobility, nutrition, friction/shear; score 6–23; ≤ 18 = at risk, ≤ 12 = high risk)
Inspect skin systematically: head, trunk (anterior/posterior), bilateral upper and lower extremities, perineum, under medical devices
Document any skin breakdown using NPUAP/EPUAP staging (Stage 1–4, Unstageable, DTPI)
Measure wounds per WOCN guidelines: length × width × depth in centimeters, tunneling, undermining
Assess mobility and ROM limitations
Evaluate assistive device use, orthotics, splints

Refer to managing-skin-integrity and managing-wound-assessment-nursing skills for detailed wound documentation.

Step 8 — Psychosocial and Safety Assessment

Screen for depression using PHQ-2 (score ≥ 3 triggers PHQ-9 completion)
Assess suicide risk per Columbia Suicide Severity Rating Scale if indicated
Evaluate substance use history and withdrawal risk (CIWA-Ar for alcohol, COWS for opioids)
Document support system, coping mechanisms, and cultural/spiritual considerations
Screen for intimate partner violence per institutional protocol
Verify safety measures: call light within reach, bed in low position, brakes locked, environment clear of hazards

Step 9 — Lines, Drains, and Device Inventory

Catalogue all invasive lines: type, location, insertion date, dressing status, patency
Document all drains: type (JP, Hemovac, chest tube, wound vac), output amount/color/characteristics per shift
Verify sequential compression devices, anti-embolic stockings, or other VTE prophylaxis devices
Check restraints if applicable (reference managing-restraint-documentation skill)
Confirm infusion pump settings match active orders for all running IV fluids and medications

[ ] Assessment supports the current nursing diagnoses and plan of care
[ ] All required screening tools completed (fall risk, Braden, PHQ-2, etc.)
[ ] Meets ANA Standard 1 (Assessment) requirements for systematic, ongoing data collection
[ ] Documentation would withstand medical-legal scrutiny: "If it wasn't documented, it wasn't done"

Guidelines

ANA Scope and Standards: Standard 1 (Assessment) requires systematic, ongoing collection of relevant data; Standard 4 (Planning) requires the assessment to drive the care plan
Joint Commission NPSGs: NPSG.01.01.01 (patient identification), NPSG.02.03.01 (critical results reporting), NPSG.06.01.01 (clinical alarm management)
CMS Conditions of Participation: §482.13 requires assessment by an RN within timeframes specified by state law and hospital policy
NANDA-I Taxonomy: All nursing diagnoses must be supported by assessment data (defining characteristics and related factors)
Documentation standard: Objective findings documented with clinical measurements; subjective data attributed to patient in quotes; clinical judgment supported by data
Frequency: Admission assessment, shift assessment, focused reassessment after interventions, reassessment for change in condition, transfer assessment — per institutional policy and state regulations
Scope of practice: RN performs comprehensive assessment; LPN/LVN may collect data under RN direction per state Nurse Practice Act; findings requiring clinical judgment must be interpreted by RN
Escalation: Any assessment finding meeting rapid response activation criteria requires immediate team activation — do not delay to complete remaining assessment components
