CCS Emergency Procedures & Response 2

Question 1

A patient in the cardiac catheterization lab develops ventricular fibrillation. What is the FIRST action?

Accepted Answer

Deliver unsynchronized defibrillation at 200J biphasic

Answer

Ventricular fibrillation is treated immediately with unsynchronized defibrillation; CPR is initiated only if a defibrillator is not immediately available.

Question 2

Which vasopressor is the first-line agent recommended in cardiac arrest according to the 2020 AHA guidelines?

Accepted Answer

Epinephrine

Answer

Epinephrine 1 mg IV/IO every 3–5 minutes remains the first-line vasopressor in cardiac arrest per AHA guidelines.

Question 3

A patient presents with ST-elevation in leads II, III, and aVF with reciprocal changes in I and aVL. Which coronary artery is most likely occluded?

Accepted Answer

Right coronary artery

Answer

Inferior STEMI (II, III, aVF) with reciprocal lateral changes classically indicates right coronary artery occlusion.

Question 4

During CPR, what is the recommended compression-to-ventilation ratio for a single rescuer managing an adult cardiac arrest?

Accepted Answer

30:2

Answer

A 30:2 compression-to-ventilation ratio is recommended for single-rescuer adult CPR to minimize interruptions in chest compressions.

Question 5

A patient develops pulseless electrical activity (PEA). Which of the following is a reversible cause represented by the 'H's'?

Accepted Answer

Hypothermia

Answer

Hypothermia is one of the 'H' reversible causes of PEA (H's and T's); it must be identified and treated to restore organized cardiac output.
