A nurse is assisting with the diagnostic workup of a client with suspected pulmonary edema. Which imaging modality can help identify the presence of fluid in the alveoli and interstitial spaces of the lungs?
Computed tomography (CT) scan
Magnetic resonance imaging (MRI)
Positron emission tomography (PET) scan
Ultrasound
The Correct Answer is A
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.

Correct Answer is B
Explanation
A) Incorrect. A decreased respiratory rate is not typically associated with pulmonary edema, which often leads to increased respiratory effort.
B) Correct. Inspiratory crackles in the lung bases are indicative of fluid accumulation in the alveoli and are a common physical finding in pulmonary edema.
C) Incorrect. Increased breath sounds are not typically associated with pulmonary edema; instead, crackles or wheezing may be heard.
D) Incorrect. Diminished heart sounds are not a characteristic finding in pulmonary edema.
Correct Answer is D
Explanation
A) Incorrect. Regular physical exercise is generally a healthy behavior and is not a risk factor for pulmonary edema.
B) Incorrect. Low blood pressure (hypotension) is not a risk factor for pulmonary edema; in fact, high blood pressure (hypertension) is a more common risk factor.
C) Incorrect. Adequate fluid intake is important for overall health but is not a direct risk factor for pulmonary edema.
D) Correct. Chronic kidney disease can lead to fluid and electrolyte imbalances, which can contribute to the development of pulmonary edema.
