Question 1

A patient in ventricular fibrillation receives a defibrillation shock. What is the FIRST action after shock delivery?

Accepted Answer

Resume CPR immediately

Answer

After defibrillation, CPR should be resumed immediately for 2 minutes before pausing to recheck rhythm, as perfusion may not be restored instantly.

Question 2

Which ECG finding is most consistent with a left bundle branch block (LBBB)?

Accepted Answer

Broad notched R wave in lead I and V5-V6 with no septal Q waves

Answer

LBBB produces a broad, notched R wave in lateral leads (I, V5-V6) with absent septal Q waves due to abnormal left ventricular depolarization.

Question 3

A 58-year-old male presents with crushing chest pain and diaphoresis. His 12-lead ECG shows ST elevation in leads II, III, and aVF. Which coronary artery is most likely occluded?

Accepted Answer

Right coronary artery

Answer

ST elevation in leads II, III, and aVF indicates an inferior wall STEMI, most commonly caused by occlusion of the right coronary artery.

Question 4

Dopamine is ordered for a patient in cardiogenic shock. At which dose range does dopamine primarily exert beta-1 adrenergic effects to increase cardiac output?

Accepted Answer

5-10 mcg/kg/min

Answer

At 5-10 mcg/kg/min, dopamine primarily stimulates beta-1 receptors, increasing heart rate and myocardial contractility to improve cardiac output.

Question 5

A patient develops pulseless electrical activity (PEA). Which of the following is a reversible cause represented by the 'H's and T's?

Accepted Answer

Hypovolemia

Answer

Hypovolemia is one of the classic 'H' reversible causes of PEA and should be treated with aggressive IV fluid resuscitation.
