1. A 49-year-old male was recently admitted with an inferior wall
MI resulting from occlusion of the right coronary artery
(RCA). The 12-Lead ECG reveals ST elevation in leads II, Ill, and avF.
You would expect to see reciprocal changes in which leads?
A. I, aVR
B. V, V2
C. V, VA
D I, aVL - 1. D. I, aVI. The RCA perfuses the inferior wall and the mirror image or
reciprocal change will be seen in the high latera wall, which is reflected in leads I, and
aVL, on the 12-Lead ECG. Leads V1 and V2 correlate with the septal area, leads V3 and
V4 correlate With the anterior area of the heart. The aVR lead does not provide much
diagnostic value as all energy is depolarizing away from this lead.

tonic-clonic convulsions while sitting in a chair. A family member states: "She was just

water." What is your initial priority of care?
A. Call for help and safely guide the patient to the floor
B. Call for help and administer a prescribed antiepileptic
C. Call for help and administer a prescribed benzodiazepine

the patient to the floor
