Stage 5 — Take action. Arrange the major STEMI decision points from ED arrival through transfer for primary PCI. Tasks assigned to different team members may proceed in parallel after activation.

Explanation
Decision sequence Obtain the ECG within 10 minutes → activate the catheterization laboratory immediately when STEMI is identified → complete aspirin confirmation, right-sided leads, IV access, and ordered studies in parallel → give prescribed antiplatelet and anticoagulant therapy after safety checks → transfer for primary PCI with continuous monitoring. Troponin and routine preparatory tasks do not precede activation as serial barriers.
Step 1 — Establish the trigger The first ECG is obtained and interpreted within 10 minutes. The ischemic symptoms and inferior ST-elevation pattern trigger immediate catheterization-laboratory activation.
Step 2 — Shift from a serial list to parallel teamwork After activation, aspirin verification, right-sided leads, IV access, blood sampling, safety checks, and prescribed medications proceed while the interventional team prepares. Biomarker results do not delay reperfusion.
Step 3 — Transfer under surveillance Maintain rhythm, hemodynamic, oxygenation, and defibrillation readiness through transfer because inferior and right ventricular infarction can produce bradyarrhythmia, heart block, or hypotension.
NCLEX rule Sequence the decision gates, but do not mistake coordinated parallel tasks for reasons to postpone definitive treatment.
Scenario (Stage 5 — Take action)The 7-minute ECG establishes inferior STEMI, and right-sided leads support right ventricular involvement.
Clinical judgment targetPrioritize immediate reperfusion activation while other safety and medication tasks continue in parallel.
Reperfusion activation — Immediate mobilization of the interventional team after STEMI is identified, without waiting for biomarker confirmation.
Decision-gate sequencing — Ordering the clinical decisions that unlock the next phase while acknowledging that assigned tasks can occur simultaneously.
Monitored transfer — Continuous rhythm and hemodynamic surveillance with resuscitation readiness during transport to definitive reperfusion.
