A client with suspected pulmonary edema is undergoing diagnostic testing. Which laboratory parameter is often elevated in cases of heart failure-related pulmonary edema?

A) Correct. Hypertension is a significant risk factor for the development of heart failure, which can lead to pulmonary edema.

B) Incorrect. Diabetes, while a chronic condition, is not a direct risk factor for pulmonary edema.

C) Incorrect. Hypercholesterolemia (high cholesterol) can contribute to atherosclerosis and cardiovascular disease but is not a direct cause of pulmonary edema.

D) Incorrect. Osteoarthritis is a musculoskeletal condition and is not directly related to the development of 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.
