Question 1

A patient is in pulseless electrical activity (PEA). Which of the 'H's' and 'T's' should be considered first in a drowning victim?

Accepted Answer

Hypoxia and Hypothermia

Answer

In drowning victims, hypoxia and hypothermia are the most likely reversible causes of PEA and should be addressed immediately.

Question 2

Which pharmacologic agent is the first-line treatment for symptomatic bradycardia due to increased vagal tone?

Accepted Answer

Atropine

Answer

Atropine 0.5 mg IV is the first-line agent for symptomatic bradycardia caused by increased vagal tone, blocking muscarinic receptors to increase heart rate.

Question 3

A 45-year-old develops a wide-complex tachycardia at 160 bpm with a pulse and altered mental status. BP is 70/40 mmHg. What is the priority treatment?

Accepted Answer

Synchronized cardioversion at 100 J

Answer

Unstable wide-complex tachycardia with hemodynamic compromise requires immediate synchronized cardioversion.

Question 4

What is the correct dose of adenosine for the first administration in SVT?

Accepted Answer

6 mg rapid IV push

Answer

The initial dose of adenosine for SVT is 6 mg given as a rapid IV push followed immediately by a 20 mL normal saline flush.

Question 5

Calcium chloride is the preferred form of calcium in cardiac arrest because:

Accepted Answer

It contains three times more elemental calcium than calcium gluconate

Answer

Calcium chloride (10%) provides approximately three times more elemental calcium per mL than calcium gluconate, making it more potent for cardiac emergencies.
