A nurse is monitoring the cardiac output of a client who has left-sided heart failure using pulse pressure analysis. Which of the following findings can compromise the readings?

The client is experiencing premature atrial contractions.

The client has bilateral wheezes.

The client has a decreased oxygen saturation level.

The client has lower leg edema.

Answer and Explanation

The Correct Answer is A

A. The client is experiencing premature atrial contractions is correct. Premature atrial contractions can interfere with pulse pressure analysis and affect the accuracy of cardiac output measurements.

B. The client has bilateral wheezes is incorrect. Wheezes affect lung function, not directly the accuracy of pulse pressure analysis for cardiac output.

C. The client has a decreased oxygen saturation level is incorrect. While it is a concern, it does not compromise pulse pressure readings directly.

D. The client has lower leg edema is incorrect. Edema affects peripheral circulation but does not directly compromise pulse pressure measurements for cardiac output.
