Question 1

A patient presents with a wide-complex tachycardia at 180 bpm. The patient is stable. The rhythm is regular. What is the first-line pharmacologic treatment if the rhythm is presumed SVT with aberrancy?

Accepted Answer

Adenosine 6 mg rapid IV push

Answer

Adenosine is the drug of choice for stable regular wide-complex tachycardia suspected to be SVT with aberrancy because it is safe and diagnostic.

Question 2

During post-cardiac arrest care, what is the recommended target range for arterial oxygen saturation (SpO2)?

Accepted Answer

94–99%

Answer

Post-ROSC oxygen should be titrated to an SpO2 of 94–99% to avoid both hypoxia and hyperoxia, which can worsen neurological outcomes.

Question 3

A patient in PEA arrest has a HR of 60 on the monitor. The team suspects cardiac tamponade. Which H or T is this classified under?

Accepted Answer

Tamponade (cardiac)

Answer

Cardiac tamponade is one of the Ts in the H's and T's of reversible causes of PEA, requiring emergency pericardiocentesis.

Question 4

When performing bag-mask ventilation during CPR with an advanced airway in place, what is the recommended ventilation rate for adults?

Accepted Answer

1 breath every 6 seconds (10/min)

Answer

Once an advanced airway is placed, deliver 1 breath every 6 seconds (10 breaths/min) asynchronously with continuous chest compressions.

Question 5

A patient develops polymorphic VT with a prolonged QTc interval. Which drug is the treatment of choice?

Accepted Answer

Magnesium sulfate 1–2 g IV

Answer

Torsades de pointes (polymorphic VT with prolonged QTc) is treated with magnesium sulfate 1–2 g IV to stabilize the myocardium.
