Purpose of this sheet: essential cardiology landmarks a nurse or licensed practical nurse in Quebec should keep in mind for clinical practice and for succeeding on the OIIQ or OIIAQ entry exam. Exam relevance: The OIIQ framework expects the nurse to promptly recognize cardiovascular changes and prioritize hemodynamic stability. — Clinical landmarks — Inferior: II, III, aVF — right coronary artery. Suspect right ventricular involvement; nitroglycerin can cause profound hypotension. Anterior: V1 to V4 — left anterior descending. The largest infarcts. Lateral: I, aVL, V5, V6 — circumflex. Septal: V1, V2. Reciprocal ST depression in the opposite leads supports a true infarction rather than a mimic. — Remember — Use this sheet in spaced repetition, pair it with a matching clinical scenario on NursEduc, and always compare values to the person's baseline before drawing conclusions.
