A client who has been anticoagulated with warfarin (Coumadin) has been admitted for gastrointestinal bleeding. The history and physical examination indicates that the client may have been taken too much warfarin. The nurse anticipates that client will receive which antidote?
Potassium chloride
Vitamin E
Protamine sulfate
Vitamin K
The Correct Answer is D
A. Potassium chloride is used to treat hypokalemia, not as a warfarin antidote.
B. Vitamin E does not counteract warfarin’s effects and may increase bleeding risk.
C. Protamine sulfate is the antidote for heparin, not warfarin.
D. Vitamin K is the appropriate antidote for excessive warfarin, as it promotes the synthesis of clotting factors inhibited by warfarin.

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.
