A nurse is caring for a 68-year-old patient who has been taking clopidogrel (Plavix) 75 mg daily for the past 3 months following a coronary stent placement. The patient is scheduled for an elective cholecystectomy in 2 weeks. What is the most important nursing action regarding the clopidogrel therapy?
1Continue the clopidogrel until the morning of surgery to maintain cardiac protection
2Reduce the clopidogrel dose to 37.5 mg daily starting one week before surgery
3Discontinue clopidogrel 5-7 days before surgery and notify the prescribing physician✓ 정답
4Switch to aspirin 81 mg daily immediately and continue through the surgical period
해설
Clopidogrel should be stopped 5-7 days before elective surgery to reduce bleeding risk, and the physician must be notified for cardiac risk management. Other options increase bleeding or thrombotic risks.
Clinical Judgment
The core of this problem is evaluating the Risk-Benefit Balance. The patient is taking an Antiplatelet medication after a myocardial infarction and is scheduled for elective surgery. The nurse must consider both the risk of excessive bleeding during surgery and the risk of thrombosis (recurrent myocardial infarction) from discontinuing the medication. The action of clopidogrel is irreversible, so new platelets must be generated for the effect to wear off. Therefore, the standard guideline is to discontinue it for an appropriate period (5-7 days) before surgery. The most important nursing action is to safely stop the medication while simultaneously notifying the prescribing physician to ensure this decision is integrated into the patient's overall cardiac care plan. The physician can then determine the need for surgery postponement or bridging therapy based on the patient's condition.
Memory Tip:
Platelet inhibition is Irreversible, so Stop before Surgery (PISS). Clopidogrel is a P2Y12 inhibitor, and its action is Irreversible, so it must be Stopped before Surgery. The key period to remember is "5 to 7" days.
KR vs US:
In Korea, the principle of discontinuing antiplatelet agents before surgery is similar, but actual clinical practice tends to follow more detailed guidelines based on the patient's cardiovascular risk (e.g., stent type, time since procedure) and emphasizes consultation with a cardiologist. In the US NGN, this element of Communication & Collaboration is highlighted even more as a core nursing judgment competency.
Clinical Practice GuideThe key to managing patients taking antiplatelet agents before elective surgery is a Multidisciplinary Approach. The nurse's role is not simply to tell the patient to stop the medication, but to accurately assess the patient's medication history, effectively communicate information between the surgical team (surgeon) and the prescribing team (cardiologist, etc.), and provide patient education. During the Preoperative Assessment, all medications (prescriptions, over-the-counter drugs, supplements) must be checked.
Caution:The trap in this question is that it presents a choice that encourages continuing the medication by emphasizing "cardiac protection" (Option 1), and "partial solutions" that appear to reduce the dose (Option 2) or switch to aspirin (Option 4). For clopidogrel, reducing the dose does not linearly decrease the bleeding risk, and switching to aspirin is a separate decision that must be made under a physician's judgment. Nurses must not independently direct medication changes.
Clopidogrel — P2Y12 ADP receptor inhibitor. A drug that irreversibly inhibits platelet aggregation, producing an antiplatelet effect. It is used for thromboprophylaxis in patients with coronary artery disease, stroke, and peripheral artery disease.
Antiplatelet Therapy — Treatment that prevents arterial thrombus formation by inhibiting platelet function. Aspirin, clopidogrel, and ticagrelor are typical examples. Balancing the risk of bleeding and the thromboprophylactic effect is important in preoperative management.
Elective Surgery — Non-emergency, elective surgery planned in advance. There is time to optimize the patient's condition before surgery and manage risk factors (e.g., taking antiplatelet medications).
Bleeding Risk — Possibility of excessive bleeding during or after surgery or a procedure. Taking antiplatelet or anticoagulant medications is a major risk factor. This is a key element of preoperative evaluation.
Platelet Function Recovery — Process by which new, fully functional platelets are produced and hemostatic function is restored after discontinuation of irreversible antiplatelet agents (e.g., clopidogrel). This generally takes 5–7 days.
