A client is admitted to the hospital with a diagnosis of acute pulmonary edema. The client has a history of hypertension and diabetes. Which comorbidity is considered a significant risk factor for the development of pulmonary edema?

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. Pink, frothy sputum, often described as "pink froth," is indicative of severe pulmonary edema with the presence of blood-tinged fluid in the alveoli.

B) Incorrect. A low-grade fever is not a typical sign of pulmonary edema and may indicate another underlying condition.

C) Incorrect. Clear breath sounds throughout the lung fields are not indicative of severe pulmonary edema, which often presents with crackles.

D) Incorrect. The absence of peripheral edema does not necessarily reflect the severity of pulmonary edema; it may be related to factors other than heart failure.
