Stage 6 — Evaluate outcomes. Review the post-PCI trend and select the best interpretation and next plan.
Trend
Choose your responses, then check the answer.
Explanation
Trend interpretation Restored TIMI grade 3 flow, marked pain relief, and more than 50 percent ST-segment resolution support successful reperfusion. A post-reperfusion troponin rise does not by itself indicate failed PCI. Continue post-PCI ischemia, rhythm, AV-conduction, hemodynamic, bleeding, and access-site monitoring and continue prescribed dual antiplatelet and secondary-prevention care.
Step 1 — Integrate the response The artery is open with TIMI 3 flow, pain is nearly resolved, and the ST elevation has fallen substantially. These findings together support effective reperfusion.
Step 2 — Interpret biomarkers in time Troponin can continue rising after reperfusion because circulating concentrations lag behind the clinical event. Recurrent symptoms, renewed ST elevation, unstable hemodynamics, or impaired angiographic flow would be more concerning for failure or reocclusion.
Step 3 — Watch inferior-MI complications Asymptomatic sinus bradycardia with mild PR prolongation requires continued rhythm and AV-conduction assessment. Escalate if bradycardia becomes symptomatic, hypotension develops, or higher-grade block appears.
Step 4 — Protect the stent and recovery Continue prescribed dual antiplatelet therapy, access-site and bleeding surveillance, secondary prevention, smoking-cessation support, and cardiac-rehabilitation planning.
NCLEX rule Evaluate a trend by combining symptoms, ECG, perfusion, rhythm, and procedure findings rather than isolating one delayed laboratory value.
Scenario (Stage 6 — Evaluate outcomes)A proximal RCA occlusion was stented with TIMI grade 3 flow. The nurse evaluates early reperfusion and post-PCI risks.
Clinical judgment targetRecognize successful reperfusion while continuing surveillance for conduction, ischemic, and bleeding complications.
TIMI grade 3 flow — Normal antegrade coronary flow beyond the treated lesion after reperfusion.
ST-segment resolution — A substantial fall in ST elevation after treatment that supports restoration of myocardial perfusion when interpreted with the clinical course.
AV-conduction monitoring — Surveillance for PR prolongation and heart block, which can occur with inferior infarction involving the AV nodal blood supply.
