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.

Correct Answer is D

Explanation

A. A difference between the apical pulse rate and the radial pulse rate is more indicative of a pulse deficit, which is not specific to constrictive pericarditis.
B. A drop in systolic blood pressure by 20 mm Hg when changing positions describes orthostatic hypotension, not paradoxical blood pressure.
C. An increase in heart rate when moving from sitting to standing reflects orthostatic changes, not paradoxical blood pressure.
D. Paradoxical blood pressure refers to a decrease in systolic blood pressure of more than 10 mm Hg during inspiration, which can occur in constrictive pericarditis due to impaired filling of the heart during diastole.

A. Lateral segment of the right lower lobe B. Lateral segment of the left lower lobe C. Posterior segment of the right middle lobe D. Posterior segment of the right lower lobe

Correct Answer is A

Explanation

A. Lateral segment of the right lower lobe is the correct answer because placing the client on the left side in Trendelenburg position promotes drainage from the right lower lobe’s lateral segment by using gravity to mobilize secretions.
B. Lateral segment of the left lower lobe would require the client to be positioned on the right side rather than the left.
C. Posterior segment of the right middle lobe would require the client to be positioned in a different way, typically supine with a slight Trendelenburg tilt.
D. Posterior segment of the right lower lobe would require a prone position in Trendelenburg, not left-side lying.
