A nurse on a telemetry unit is caring for a client who has premature ventricular contractions (PVCs). While sitting in a chair, the client reports feeling lightheaded. If the client is having PVCs, which of the following findings should the nurse expect when auscultating the client's apical pulse?

Irregular pulsations

Bounding pulsations

Tachycardia

Bradycardia

Answer and Explanation

The Correct Answer is A

A. Irregular pulsations are expected with PVCs because they cause occasional early beats that disrupt the regular rhythm of the pulse.

B. Bounding pulsations are not specific to PVCs and are more indicative of conditions like high cardiac output states.

C. Tachycardia is not a direct finding associated with PVCs; PVCs are more about irregular beats rather than a consistently high heart rate.

D. Bradycardia is not typically associated with PVCs; PVCs are characterized by irregular beats but not necessarily a slow heart rate.
