A nurse is caring for a client with a history of myocardial infarction (MI). Which factor related to the client's medical history increases the risk of developing pulmonary edema?

A) Incorrect. Hyperventilation leading to respiratory alkalosis may occur in response to respiratory distress but is not the primary cause of the sensation of "suffocation."

B) Incorrect. Reduced cardiac output may be a consequence of pulmonary edema, but it does not typically result in bradycardia, nor is it the primary cause of the sensation described.

C) Correct. In pulmonary edema, fluid accumulation in the alveoli impairs oxygen diffusion, leading to hypoxemia, which contributes to the sensation of "suffocation."

D) Incorrect. Elevated blood pressure and hypertension can be associated with heart failure but are not the primary factors contributing to the sensation of "suffocation" in pulmonary edema.

A) Incorrect. Increased lung compliance would not contribute to pulmonary edema; in fact, it might reduce the risk of fluid accumulation in the lungs.

B) Correct. Impaired alveolar fluid clearance, often due to altered pulmonary capillary permeability, is a key factor in the pathophysiology of pulmonary edema.

C) Incorrect. Constricted pulmonary blood vessels (vasoconstriction) would reduce blood flow to the lungs and are not a primary factor in pulmonary edema.

D) Incorrect. Enhanced left ventricular contractility, while beneficial for cardiac function, is not directly related to the development of pulmonary edema.
