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.
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.

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.
Correct Answer is D
Explanation
A. Advise the client to place one nitroglycerin tablet under his tongue as a precaution: Nitroglycerin is contraindicated in combination with phosphodiesterase type 5 inhibitors like tadalafil due to the risk of severe hypotension. This action could worsen the client's condition.
B. Tell the client to have someone bring him to an emergency department immediately: Skin flushing is a common side effect of tadalafil and not necessarily indicative of a medical emergency, especially in the absence of chest pain or other concerning symptoms.
C. Instruct the client to increase his intake of oral fluids until the skin flushing is relieved Increasing fluid intake is not likely to alleviate the skin flushing associated with tadalafil. This response does not address the client's concern adequately.
D. Reassure the client that skin flushing is a common side effect of the medication: Tadalafil, a phosphodiesterase type 5 inhibitor, commonly causes facial flushing as a side effect. Reassuring the client about this known side effect is appropriate, especially since he is not experiencing chest pain or other concerning symptoms.
