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.

Correct Answer is A

Explanation

A. A murmur is the expected heart sound in mitral valve regurgitation, caused by the backflow of blood into the left atrium during systole. It is typically a holosystolic murmur heard best at the apex of the heart.
B. S3 and S4 heart sounds may be heard in heart failure but are not specific for mitral regurgitation.
C. A friction rub is associated with pericarditis, not valvular disease.
D. A click is typically heard in mitral valve prolapse, not mitral regurgitation.

A. Hold all medications B. Keflex (Cephalexin) C. Tenormin (Atenolol) D. Heparin

Correct Answer is C

Explanation

A. Holding all medications is not necessary; only certain medications that affect heart rate or blood pressure are held.
B. Keflex (Cephalexin) is an antibiotic and does not affect stress test results, so it should not be held.
C. Tenormin (Atenolol) is a beta-blocker that reduces heart rate and can interfere with the stress test by blunting the expected heart rate response. Beta-blockers are typically held before an exercise stress test.
D. Heparin is an anticoagulant and does not impact the stress test results.
