Question

A 35 y/o woman has palpitations, light-headedness, and a stable tachycardia. The monitor shows a regular narrow-complex QRS at a rate of 180/min. Vagal maneuvers have not been effective in terminating the rhythm. An IV has been established. Which drug should be administered?

-adenosine 6 mg
-atropine 0.5 mg
-epinephrine 2 to 10 mcg/kg per minute
-lidocaine 1 mg/kg

Answer 1

The appropriate drug to administer in order to terminate the rhythm in a 35 y/o woman with palpitations, light-headedness, and stable tachycardia is adenosine 6 mg.

Step-by-step explanation:

In this case, a 35 y/o woman with palpitations, light-headedness, and stable tachycardia at a rate of 180/min is not responding to vagal maneuvers. In order to terminate the rhythm, the appropriate drug to administer would be adenosine 6 mg. Adenosine is a medication commonly used for the treatment of supraventricular tachycardia (SVT) as it slows conduction through the AV node and interrupts the reentry pathway responsible for the tachycardia.
