Quick answerThe teach-back should match the written plan:
last therapeutic enoxaparin dose about 24 hours before surgery.
Why this is correctTherapeutic-dose LMWH given too close to surgery leaves clinically important anticoagulant activity and increases bleeding risk. Restart timing is individualized to hemostasis and procedural bleeding risk.
Easy analogy or mental pictureCreate a protected gap around the procedure, then reopen anticoagulation only when the surgical team confirms it is safe.
Memory hookTherapeutic LMWH: think 24 hours before.NCLEX decision ruleUse the ordered perioperative schedule, dose intensity, renal function, and bleeding risk; never improvise a hold or restart.
Why the other choices are wrongA day-of-surgery dose is too close, a 7-day hold creates an unnecessary gap, and visible bleeding is not the criterion for continuing anticoagulation through surgery.
