Introduction
Scenario setup You are assigned to a 70-year-old recovering from bowel surgery. The client reports rigors and increasing weakness. Vitals: BP 100/60 mmHg, HR 120/min, RR 30/min, SpO₂ 94% on 2 L via nasal prongs, temperature 38.5°C. The client is disoriented to place. Abdomen is tender across the lower quadrants; drain output looks cloudy compared with earlier. You note oliguria on the last two voids. This is a deteriorating postoperative picture with systemic inflammatory features and possible source (abdomen/device/drain). Canadian items still test the same prioritization spine: ABC, perfusion, infection source, timely collaboration. RPN answers emphasize standards-aligned assessment, clear reporting, and safe scope—not diagnosing independently beyond assessment data. REx-PN traps include delaying notification to complete tasks, minimizing confusion as “normal for older adults,” or choosing independent prescription-level actions. Prefer objective data, prompt communication, and ordered interventions. This case-study format is intentional: boards reward —what changed, what is unstable, and what you do for the named in the stem. For , read the before you eliminate answers. re-scan the stem for ,...
