What medication is given to ESRD patients DURING each hemodialysis session?
Show answer and explanation
Correct answer: B. Heparin (to prevent clotting in the dialysis circuit)
Heparin is administered intravenously DURING each hemodialysis session to prevent clotting in the extracorporeal circuit (dialysis machine tubing and membranes). Its effect clears within hours post-dialysis. This is why dental appointments are ideally scheduled the day AFTER dialysis — heparin has cleared and electrolytes/fluid status are optimal.
- A. ❌ Erythropoietin treats anemia in ESRD but is given less frequently (weekly/monthly) — not during each session.
- B. ✅ Heparin is given DURING each dialysis session to prevent circuit clotting.
- C. ❌ Warfarin is oral long-term anticoagulation — not given during dialysis sessions.
- D. ❌ Aspirin is antiplatelet — not the standard anticoagulant used during hemodialysis.
