Question 1

After successful resuscitation from VF cardiac arrest, targeted temperature management (TTM) is most beneficial for which patient population?

Accepted Answer

Comatose survivors of out-of-hospital cardiac arrest

Answer

TTM at 32–36°C is indicated for comatose post-cardiac arrest patients to reduce neurological injury from reperfusion damage.

Question 2

A rhythm strip shows a regular rate of 150 bpm with a sawtooth baseline and 2:1 conduction. This most likely represents:

Accepted Answer

Atrial flutter with 2:1 conduction

Answer

Atrial flutter characteristically produces a sawtooth F-wave pattern at ~300 bpm with the ventricular rate at a fraction determined by AV conduction ratio.

Question 3

The correct pad placement for anterior-posterior defibrillation uses one pad:

Accepted Answer

Center of chest and between the scapulae on the back

Answer

Anterior-posterior placement positions one pad over the precordium and the other on the posterior left thorax to maximize current through the heart.

Question 4

Which drug is first-line for treating symptomatic sinus bradycardia in a hemodynamically stable patient?

Accepted Answer

Atropine 0.5 mg IV

Answer

Atropine 0.5 mg IV is the first-line agent for symptomatic bradycardia, reversing vagal-mediated slowing of the SA and AV nodes.

Question 5

During CPR, the recommended compression-to-ventilation ratio for a single rescuer treating an adult victim is:

Accepted Answer

30:2

Answer

Current AHA guidelines specify a 30:2 compression-to-ventilation ratio for single-rescuer adult CPR to minimize interruptions to chest compressions.
