A patient in the cardiac catheterization lab develops ventricular fibrillation. What is the FIRST action?
Answer: Deliver unsynchronized defibrillation at 200J biphasic
Ventricular fibrillation is treated immediately with unsynchronized defibrillation; CPR is initiated only if a defibrillator is not immediately available.
Which vasopressor is the first-line agent recommended in cardiac arrest according to the 2020 AHA guidelines?
Answer: Epinephrine
Epinephrine 1 mg IV/IO every 3–5 minutes remains the first-line vasopressor in cardiac arrest per AHA guidelines.
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?
Answer: Right coronary artery
Inferior STEMI (II, III, aVF) with reciprocal lateral changes classically indicates right coronary artery occlusion.
During CPR, what is the recommended compression-to-ventilation ratio for a single rescuer managing an adult cardiac arrest?
Answer: 30:2
A 30:2 compression-to-ventilation ratio is recommended for single-rescuer adult CPR to minimize interruptions in chest compressions.
A patient develops pulseless electrical activity (PEA). Which of the following is a reversible cause represented by the 'H's'?
Answer: Hypothermia
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.
What is the maximum dose of adenosine for terminating supraventricular tachycardia if the initial 6 mg dose fails?
Answer: 12 mg
If the initial 6 mg adenosine dose fails, a second dose of 12 mg IV push may be administered, with a possible third dose of 12 mg.
A post-cardiac-arrest patient achieves ROSC. Target temperature management (TTM) should maintain core temperature at:
Answer: 34–36°C for 24 hours or longer
Current guidelines support targeted temperature management at 32–36°C for at least 24 hours after ROSC to improve neurological outcomes.
