Question

The nurse cares for a client who has developed junctional tachycardia with a heart rate (HR) of 80 bpm. Which action should the nurse complete?

1) Request a digoxin level be ordered
2) Withhold the client's oral potassium supplement
3) Prepare for emergent electrical cardioversion
4) Prepare to administer IV lidocaine

Answer 1

Junctional tachycardia is a type of arrhythmia characterized by a fast heart rate originating in the AV node. In this case, the client has a heart rate of 80 bpm, which is within the normal range. Therefore, no immediate action is required.

Step-by-step explanation:

Junctional tachycardia is a type of arrhythmia characterized by a fast heart rate originating in the AV (atrioventricular) node. In this case, the client has a heart rate of 80 bpm, which is within the normal range (60-100 bpm). Therefore, there is no need to administer medications such as digoxin or lidocaine, or to withhold the client's oral potassium supplement. Additionally, emergent electrical cardioversion is not indicated as the client's heart rate is not dangerously high. The nurse should continue to monitor the client's heart rate and assess for any other signs or symptoms of distress.
