A 58-year-old male presents with diaphoresis, jaw pain, and an ECG showing ST elevation in leads II, III, and aVF. Which coronary artery is most likely occluded?
Answer: Right coronary artery
Inferior STEMI (ST elevation in II, III, aVF) is most commonly caused by occlusion of the right coronary artery.
Which of the following is the correct energy setting for synchronized cardioversion of stable atrial flutter?
Answer: 50–100J biphasic
Atrial flutter typically responds to low-energy synchronized cardioversion starting at 50–100J biphasic.
A patient has third-degree (complete) heart block with a ventricular rate of 30 bpm and hypotension. Which treatment is most appropriate?
Answer: Transcutaneous pacing
Transcutaneous pacing is the definitive prehospital treatment for symptomatic third-degree heart block.
In ACLS, what is the maximum single IV/IO dose of adenosine for SVT?
Answer: 12mg
The maximum single dose of adenosine is 12mg; if the initial 6mg dose fails, a repeat dose of 12mg may be given.
Which rhythm is most commonly seen immediately after successful defibrillation of ventricular fibrillation?
Answer: PEA or asystole
Post-defibrillation PEA or asystole is common and requires immediate resumption of CPR for 2 minutes.
For a patient in cardiac arrest with suspected hyperkalemia, which medication should be given to stabilize the cardiac membrane?
Answer: Calcium chloride 1g IV
Calcium chloride (or calcium gluconate) stabilizes the myocardial cell membrane against the effects of hyperkalemia.
According to AHA guidelines, what is the recommended fraction of chest compressions (CCF) target during resuscitation?
Answer: Greater than 60%
The 2020 AHA guidelines recommend a chest compression fraction of greater than 60% to maximize perfusion during CPR.
