Question

A patient is in refractory ventricular fibrillation. High-quality CPR is in progress. One dose of epinephrine was given after the second shock. An antiarrhythmic drug was given immediately after the third shock. You are the team leader. Which medication do you order next?

A. epinephrine 1 mg
B. epinephrine 3 mg
C. sodium bicarbonate 50 mEq
D. a second dose of the antiarrhythmic drug

Answer 1

The next medication to order for a patient in refractory ventricular fibrillation after one dose of epinephrine and an antiarrhythmic drug is another dose of epinephrine 1 mg, to be repeated every 3-5 minutes.

Step-by-step explanation:

As the team leader for a patient in refractory ventricular fibrillation, you are managing a life-threatening situation where high-quality CPR is in progress and one dose of epinephrine has already been given after the second shock, followed by an antiarrhythmic drug after the third shock. According to Advanced Cardiovascular Life Support (ACLS) guidelines, the next medication to order would be epinephrine 1 mg, which can be repeated every 3-5 minutes during cardiac arrest. The use of additional antiarrhythmic drugs or other medications like sodium bicarbonate is typically reserved for specific scenarios and is not the immediate next step after the initial dose of an antiarrhythmic drug. It is critical to continue high-quality CPR and follow ACLS algorithms for the best possible patient outcomes.
