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. 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.

A) Correct. Serum creatinine levels can be elevated in cases of heart failure-related pulmonary edema, indicating impaired kidney function due to reduced cardiac output.

B) Incorrect. Blood glucose levels may be elevated in some individuals with diabetes but are not directly related to pulmonary edema.

C) Incorrect. Hemoglobin levels are not typically used to diagnose pulmonary edema; they are more related to oxygen-carrying capacity in the blood.

D) Incorrect. Serum potassium levels may be influenced by various factors but are not a primary indicator of pulmonary edema.
