A nurse is reviewing the chart of a client who has a prescription for eptifibatide. The nurse should identify which of the following medications as a contraindication for this medication?

Choice A reason: Warfarin is an anticoagulant, and when combined with eptifibatide, which is a glycoprotein IIb/IIIa inhibitor that prevents platelet aggregation, the risk of severe bleeding increases significantly. This drug interaction is contraindicated because it can lead to life-threatening hemorrhage. This makes Warfarin the correct answer. Choice B reason: Metoprolol is a beta-blocker used for hypertension and cardiac conditions. It does not directly interact with eptifibatide in a way that increases bleeding risk. Therefore, it is not contraindicated. Choice C reason: Sertraline is an SSRI antidepressant. While SSRIs can increase bleeding risk slightly due to platelet effects, they are not considered absolute contraindications with eptifibatide. The risk is lower compared to anticoagulants like warfarin. Choice D reason: Lisinopril is an ACE inhibitor used for hypertension and heart failure. It does not have a direct interaction with eptifibatide that would contraindicate use. While monitoring for hypotension and renal function is necessary, it is not a contraindication.
