Physiological Integrity: Reduction of Risk Potential
What this domain tests
Reduction of Risk Potential tests early recognition of complications, laboratory and diagnostic interpretation, perioperative care, fall and pressure-injury risk, and monitoring for deterioration. The exam favors questions where a subtle change signals a preventable event.
Core rules
- Trend vital signs and early-warning scores; a rising respiratory rate, falling urine output, or new confusion is significant.
- Act on critical laboratory values per policy; report and document.
- Prevent venous thromboembolism with risk assessment, early mobility, hydration, and prescribed prophylaxis.
- Use surgical safety checks: consent, site marking, allergies, fasting, and retained-item counts.
- Monitor oxygen safety: no smoking near oxygen, secure tubing, and check the delivery device.
Worked example
Postoperative day 1: client has heart rate 118, blood pressure 92/60, urine output 20 mL/hour, and cool skin. The nurse should recognize possible hypovolemia or hemorrhage, reassess, notify the provider, prepare for fluids and blood work, and document. Reasoning: tachycardia, hypotension, oliguria, and cool skin are early shock signs; waiting for a dramatic drop misses the window for intervention.
Traps
- Accepting "normal for age" when the trend is abnormal.
- Ignoring a falling urine output because blood pressure is still borderline.
- Failing to reconcile anticoagulants before surgery.
- Documenting a concern without escalating it.
