A) Left anterior descending (LAD)
B) Right coronary artery (RCA)
C) Left circumflex artery
D) Posterior descending artery
Rationale: ST-elevation in II, III, aVF indicates inferior wall MI,
which is most commonly due to RCA occlusion.
2. Which of the following vaccines is recommended for all

A) Random glucose 150 mg/dL
B) Fasting plasma glucose ≥126 mg/dL on two occasions
C) HbA1c 5.5%
