A client with heart failure develops pulmonary edema. Which part of the heart's pumping action is impaired in this condition, leading to fluid backup in the lungs?

Atrial contraction

Ventricular relaxation (diastole)

Ventricular contraction (systole)

Electrical conduction in the heart

Answer and Explanation

The Correct Answer is C

A) Incorrect. Atrial contraction contributes to ventricular filling but is not typically the primary site of impairment in heart failure leading to pulmonary edema.

B) Incorrect. Ventricular relaxation (diastole) is necessary for ventricular filling, but the impaired contraction during systole is a more common issue in heart failure.

C) Correct. Impaired ventricular contraction (systole) in heart failure results in reduced forward flow of blood and leads to fluid backup in the lungs, contributing to pulmonary edema.

D) Incorrect. Electrical conduction in the heart may affect heart rhythm but is not directly related to the development of pulmonary edema.

Correct Answer is C

Explanation

A) Incorrect. A high-sodium diet is not recommended for clients with pulmonary edema, as it can exacerbate fluid retention.

B) Incorrect. Low-potassium diets are not typically recommended for clients with pulmonary edema, as potassium is important for heart and muscle function.

C) Correct. A low-sodium diet is essential to reduce fluid retention and manage pulmonary edema.

D) Incorrect. While adequate protein intake is important for overall health, it is not the primary dietary concern in pulmonary edema.

A. Supine position with legs elevated B. High Fowler's position C. Left lateral recumbent position D. Prone position with the head turned to the side

Correct Answer is B

Explanation

A) Incorrect. The supine position with legs elevated is not recommended for clients with pulmonary edema, as it can worsen fluid retention.

B) Correct. High Fowler's position allows for optimal lung expansion and improved gas exchange in clients with pulmonary edema.

C) Incorrect. The left lateral recumbent position may be used in some cases, but it is not the primary position for managing pulmonary edema.

D) Incorrect. The prone position is not typically recommended for clients with pulmonary edema.
