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.

Correct Answer is ["C","D"]

Explanation

A. Modern pacemakers are designed to withstand interference from microwave ovens, so it is not necessary to avoid having them in the home.
B. Airport security staff should be informed about the pacemaker, but handheld metal detectors should be avoided because prolonged exposure can interfere with pacemaker function. Instead, the client should request a manual search.
C. Monitoring the pulse daily helps to ensure the pacemaker is functioning properly and to detect any irregularities early.
D. Wearing tight clothing over the insertion area can cause discomfort and may interfere with the function of the pacemaker.
E. Activities that involve jolting or the risk of impact to the pacemaker should be avoided until cleared by a healthcare provider, and this period may extend beyond 4 weeks.

A. The client has a paralytic ileus. B. The client is experiencing a myocardial infarction. C. The client who has bronchitis pleurisy. D. The client who is 24 hr postoperative following hip arthroplasty.

Correct Answer is A

Explanation

A. The client has a paralytic ileus is correct. Morphine can cause decreased gastrointestinal motility, which can exacerbate a paralytic ileus.

B. The client is experiencing a myocardial infarction is incorrect. Morphine is commonly used to manage pain and reduce myocardial oxygen demand during a myocardial infarction.

C. The client who has bronchitis pleurisy is incorrect. Morphine can be used for pain control in pleurisy, but it is not contraindicated.

D. The client who is 24 hr postoperative following hip arthroplasty is incorrect. Morphine is used for postoperative pain management.
