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.
