Question 1 of 5
Which of the following drugs was most likely administered?
Correct Answer: C
Rationale: Step-by-step rationale for why choice C (Adenosine) is correct: 1. Adenosine is used for supraventricular tachycardia due to its ability to slow conduction through the AV node. 2. Mexiletine and Lidocaine are sodium channel blockers used for ventricular arrhythmias, not supraventricular tachycardia. 3. Amiodarone is a broad-spectrum antiarrhythmic used for various types of arrhythmias, not specific to supraventricular tachycardia. Summary: Adenosine is the correct answer because of its specific mechanism of action in treating supraventricular tachycardia. Mexiletine, Lidocaine, and Amiodarone are used for different types of arrhythmias, making them incorrect choices.
