Which condition would prompt reducing heparin dose and possibly shortening dialysis time?

• A. Regular dialysis without adjustment
• B. Increase heparin dose
• C. Remove dialysis catheters
• D. Upcoming surgery

Answer: (D)

Anticoagulation during dialysis is adjusted when there’s a risk of bleeding, such as before a planned surgery. Heparin prevents clotting in the circuit but increases bleeding risk for the patient. If surgery is upcoming, you reduce the heparin dose to lower the chance of perioperative bleeding and you may shorten the dialysis time to limit overall anticoagulant exposure. The other situations don’t address the heightened bleeding risk: regular dialysis without adjustment wouldn’t change the bleeding risk, increasing heparin would raise it, and removing dialysis catheters isn’t about anticoagulation levels.
