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

Answer and Explanation

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 C

Explanation

A) Incorrect. A persistent dry cough is not a typical symptom of acute pulmonary edema.

B) Incorrect. Productive cough with green sputum is more suggestive of a respiratory infection than acute pulmonary edema.

C) Correct. Sudden-onset severe shortness of breath, often described as "air hunger," is a hallmark symptom of acute pulmonary edema.

D) Incorrect. Sharp, stabbing chest pain is not a primary symptom of acute pulmonary edema but may be present in some cases.

A. Increased myocardial contractility B. Reduced afterload on the heart C. Left ventricular remodeling D. Enhanced pulmonary vasodilation

Correct Answer is C

Explanation

A) Incorrect. Increased myocardial contractility would not typically lead to left ventricular remodeling but might improve cardiac function.

B) Incorrect. Reduced afterload on the heart may be beneficial, but it is not a primary factor in left ventricular remodeling.

C) Correct. Left ventricular remodeling, often occurring after a myocardial infarction, involves changes in the size and shape of the ventricle, which can impair cardiac function and lead to pulmonary edema.

D) Incorrect. Enhanced pulmonary vasodilation is not a primary cause of left ventricular remodeling or pulmonary edema.
