Question 1 of 5

Which of the following drugs was most likely the second drug administered to a patient with atrial fibrillation and wide QRS after being given amiodarone?

Correct Answer: F

Rationale: The correct answer is B: Mexiletine. After administering amiodarone for atrial fibrillation and wide QRS, the next drug should target the wide QRS complex, indicating possible ventricular involvement. Mexiletine, a Class IB antiarrhythmic, is commonly used to treat ventricular arrhythmias. Lidocaine (A) is also a Class IB antiarrhythmic, but Mexiletine is preferred in this scenario due to its longer half-life. Phenytoin (C) is not indicated for atrial fibrillation or wide QRS. Nifedipine (D) is a calcium channel blocker and is not appropriate for treating ventricular arrhythmias.
