Which assessment finding indicates a patient has had a favorable response to adenosine (Adenocard)?

1. Complaints of a headache
2. Heart rate decreased to 80
3. Converts to sustained asystole
4. Heart rate increased to 64


2
Rationale 1: A headache is not a favorable response to adenosine.
Rationale 2: Adenosine is given for supraventricular tachycardia.Converting to a normal heart rate is considered successful treatment.
Rationale 3: A short period of asystole is sometimes experienced immediately after administration but not sustained asystole. This would be an adverse response to adenosine.
Rationale 4: An increase in heart rate to 64 would have indicated a bradycardic rate for which adenosine is not recommended.
