Health Assessment and Clinical Decision-Making

The Health Assessment and Clinical Decision-Making domain tests whether you can gather focused data, recognize deterioration early, and prioritize actions. Questions often present a changing patient and ask for the first or best response.

Core rules and concepts

  • Use the nursing process: assess, diagnose (nursing), plan, implement, evaluate. Reassess after every intervention.
  • A comprehensive assessment is baseline; a focused assessment targets the presenting problem. ABCs (airway, breathing, circulation) come before comfort and routine tasks.
  • Abdominal sequence: inspect, auscultate, percuss, palpate. For other systems, inspect, palpate, percuss, auscultate as appropriate.
  • Know adult norms: heart rate 60-100, respiratory rate 12-20, temperature about 36.5-37.5 C, oxygen saturation usually 94% or higher on room air. Trends matter more than a single value.
  • Early deterioration signals include rising respiratory rate, tachycardia, new confusion, falling blood pressure, oliguria, and cool extremities. Escalate using SBAR and the early warning system.
  • Prioritize unstable over stable, acute over chronic, and actual over potential problems, while maintaining safety.

Worked example

Postoperative day one: heart rate 118, BP 92/60, urine 15 mL/hr, cool extremities, new confusion. The nurse does not label this as anxiety. She completes a focused assessment, checks the dressing and drainage, mental status, and capillary refill, and recognizes possible hypovolemia or hemorrhage. She notifies the provider with SBAR, anticipates a fluid bolus, labs, and possible transfusion, and reassesses. Reasoning: the cluster of tachycardia, hypotension, oliguria, and confusion points to decreased perfusion, not a single abnormal number.

Traps that cost marks

  • Treating one vital sign instead of the trend and the cluster.
  • Skipping a focused assessment before calling the provider.
  • Attributing tachycardia or confusion to anxiety or age without ruling out physiologic causes.
  • Delaying escalation while waiting for the next scheduled round.
