A client has a prescription for clopidogrel bisulfate 75 mg by mouth daily at 0900. In which situation should the nurse hold this medication?

A. The client's platelet level is high: A high platelet count generally indicates an increased risk of clotting, and clopidogrel, as an antiplatelet agent, is continued to prevent thrombotic events. Holding due to a high platelet level is not warranted without additional concerns. B. Breakfast has not been eaten: Clopidogrel can be taken with or without food, so withholding the medication because the client has not eaten breakfast is unnecessary. The timing of food intake does not greatly affect the medication’s effectiveness or absorption. C. Elective surgery is scheduled in two hours: Clopidogrel increases bleeding risk, and holding it before surgery is essential to reduce perioperative bleeding complications. It is standard practice to withhold antiplatelet agents several days before elective surgical procedures to allow platelet function to normalize. D. An abdominal sonogram is scheduled: An abdominal sonogram is a noninvasive imaging test and does not increase bleeding risk; therefore, clopidogrel does not need to be held prior to the procedure. The medication can be safely continued in this situation.
