A nurse is caring for a client who reports shortness of breath and heart palpitations. An ECG confirms the client is experiencing ventricular tachycardia (VT). The nurse palpates a rapid carotid pulse with a blood pressure of 70/30, and the client reports feeling dizzy. The nurse should anticipate the need for which priority action?

Initiate external pacing.

Initiate CPR.

Defibrillation.

Synchronized cardioversion.

Answer and Explanation

The Correct Answer is D

A. External pacing is not indicated for ventricular tachycardia with a pulse. Pacing is typically used for bradyarrhythmias.
B. CPR is only necessary if the client is pulseless. Since the client has a pulse, a more appropriate intervention is needed.
C. Defibrillation is used for pulseless VT or ventricular fibrillation, but this client has a pulse and is symptomatic.
D. Synchronized cardioversion is the appropriate intervention for unstable ventricular tachycardia with a pulse. The shock is synchronized to the R wave to prevent inducing ventricular fibrillation.

B. Atorvastatin, a statin medication, is not known to interact with contrast dye or cause kidney injury in this context.

B. A regular exercise routine is beneficial for cardiovascular health and helps lower blood pressure rather than increasing it.
C. Benazepril is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension rather than causing it.
