A client with heart failure develops pulmonary edema. Which part of the heart's pumping action is impaired in this condition, leading to fluid backup in the lungs?

A) Incorrect. Intravenous antibiotics may be necessary for certain pulmonary infections, but they do not address the immediate oxygenation needs in acute pulmonary edema.

B) Correct. Providing supplemental oxygen helps increase the client's oxygen levels, improving oxygenation in acute pulmonary edema.

C) Incorrect. While deep breathing exercises are beneficial for overall lung health, they may not be sufficient to address the immediate oxygenation issue in acute pulmonary edema.

D) Incorrect. Antipyretic medications are used to reduce fever and do not directly improve oxygenation in pulmonary edema.

A) Correct. A CT scan can help identify the presence of fluid in the alveoli and interstitial spaces of the lungs, making it a valuable tool in diagnosing pulmonary edema.

B) Incorrect. MRI is not typically used to diagnose pulmonary edema, as it may not provide as clear an image of lung tissue as a CT scan.

C) Incorrect. PET scans are more commonly used in oncology to detect metabolic activity and are not typically used for pulmonary edema diagnosis.

D) Incorrect. While ultrasound can be useful in assessing pleural effusions, it may not provide the same level of detail as a CT scan for diagnosing pulmonary edema.
