For a client with chronic kidney disease on heparin, which prescription should the nurse question?

• A. Epoetin
• B. Sodium polystyrene sulfonate
• C. Vitamin K
• D. Warfarin

Answer: (C)

In the context of a client with chronic kidney disease receiving heparin, the prescription for vitamin K should be questioned because vitamin K is an antidote for warfarin, a medication that works as an anticoagulant by inhibiting vitamin K-dependent clotting factors. If a patient is already on heparin, which is also an anticoagulant, administering vitamin K could lead to complications such as increased coagulation and the risk of thrombotic events, especially since heparin and warfarin have different mechanisms of action. Epoetin is commonly used to manage anemia in patients with chronic kidney disease and does not directly interact with heparin in the way that vitamin K would. Sodium polystyrene sulfonate is utilized for treating hyperkalemia in renal patients and is appropriate in this context. Warfarin would also be contraindicated for use alongside heparin without careful monitoring, but it is not as immediately problematic as vitamin K in this scenario. Overall, vitamin K is the most inappropriate choice given the patient’s current treatment with heparin and the risks associated with inadvertent anticoagulation reversal.
