Introduction
Scenario setup A 48-year-old with HTN and family history reports episodes of exertional chest tightness relieved by rest, now more frequent. Today pain occurs at rest for 20 minutes with diaphoresis. Vitals in office: BP 132/84, HR 88, RR 18, SpOโ 98%. ECG shows nonspecific changes; first troponin pending. This is unstable angina / possible ACS in an ambulatory context. NP reasoning focuses on risk stratification, immediate ED referral when red flags exist, and avoiding false reassurance when symptoms escalate to rest pain with autonomic features. NP traps: sending home with only PPI for โGERDโ when ischemic features dominate; ordering stress tests as first step during ongoing rest pain; vague follow-up. This case-study format is intentional: boards reward trajectory thinkingโwhat 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 onsetโcase items often hide the decisive clue in a single line. On the exam, writers often...
