Introduction
Scenario setup An ambulatory NP message system flags a 58-year-old with fever, rigors, and dysuria for 36 hours. They report lightheadedness when standing and only 200 mL urine since yesterday. Vitals at the clinic: BP 98/60, HR 112, RR 22, SpO₂ 97%, T 38.8°C. They look tired but alert. No chest pain. PMH: diabetes, recurrent UTIs. This case tests whether you treat febrile UTI as uncomplicated ambulatory illness versus early sepsis with perfusion compromise. NP-level reasoning includes risk stratification, cannot-miss alternatives, and site-of-care (outpatient management vs urgent ED evaluation) based on objective data—not reassurance alone. NP traps: prescribing oral antibiotics while ignoring hypotension, tachycardia, and oliguria; ordering exhaustive testing without addressing instability; or ambiguous safety netting. Items reward clear escalation thresholds and specific follow-up. This case-study format is intentional: boards reward trajectory thinking—what changed, what is unstable, and what you do next for the role named in the stem. For NP certification preparation (United States), read the assignment line before you eliminate answers. Slow read: re-scan the stem for vitals trends, oxygen settings, allergies, and time since onset—case items often...
