A client with suspected pulmonary edema is scheduled for an echocardiogram. What information can this diagnostic test provide to assist in diagnosing the cause of 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) 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.
