Key Concepts
Introduction
RN You lead bedside stabilization: ECG timing, serial troponins per orders, antiplatelet/anticoagulant administration, nitro/morphine per orders and contraindications, oxygen only when indicated, and prep for PCI/thrombolysis as the stem describes. Items test prioritization among multiple patients and contraindication knowledge. STEMI teaching often stresses reperfusion urgency; NTG traps with RV infarct (inferior MI + JVD/hypotension cues); morphine cautions with respiratory depression; O₂ not routine if saturations normal in modern stems. For NCLEX-RN (United States), questions rarely announce the topic in the first sentence. They hide it inside vitals, labs, and a short story. Your job is to name the clinical problem, justify why it matters now, and select the safest next step for the role you are given—before you let distractors pull you toward busywork or out-of-scope heroics. When two answers feel partly right, pick the one that closes risk first and matches your license in the stem. On the exam, writers often pair stable-sounding options with unstable data—notice the mismatch before you commit. If the stem names a license or role, reread that line; scope errors are classic trap answers...
