Correct Answer is D

Explanation

A. Although monitoring hemodynamic parameters is important, this option does not address the immediate issue of low preload, as indicated by the low CVP and PAWP, suggesting hypovolemia.

B. Furosemide is a diuretic and would further decrease intravascular volume, which is inappropriate given the signs of hypovolemia.

C. Decreasing IV fluids would exacerbate the low preload and worsen the client's condition by reducing intravascular volume even further.

D. Administering 0.9% Normal Saline @ 150 mL/hr is the most appropriate intervention. The low CVP and PAWP indicate hypovolemia, and increasing fluid administration will help to increase the preload, thereby improving the client's hemodynamic status.

A. Assess the client's respiratory status. B. Ask the client about current medications. C. Administer intravenous furosemide. D. Draw blood to assess the client's serum electrolytes.

Correct Answer is A

Explanation

A. Assessing respiratory status is the priority in heart failure exacerbation, as respiratory distress can rapidly worsen and affect oxygenation.

B. While knowing current medications is important, the priority in this situation is addressing the client's respiratory needs.

C. Administering furosemide is part of the management plan but should follow the initial assessment of the client's condition, especially respiratory status.

D. Drawing blood is helpful but not the immediate priority in managing acute heart failure exacerbation.
