A client with a history of myocardial infarction (MI) develops pulmonary edema. Which pathophysiological process is likely occurring in this client, leading to fluid accumulation in the lungs?

A) Correct. Pink, frothy sputum is often referred to as hemoptysis and is a common presentation in pulmonary edema.

B) Incorrect. Orthopnea refers to difficulty breathing when lying flat and is associated with heart failure but is not specifically related to pink, frothy sputum.

C) Incorrect. Paroxysmal nocturnal dyspnea (PND) is another symptom of heart failure but does not involve the coughing up of pink, frothy sputum.

D) Incorrect. Crepitus is a term used to describe a crackling or popping sound and is not directly related to the sputum seen 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.
