What condition would contraindicate systemic heparin use during dialysis?

• A. Active bleeding or very high bleeding risk.
• B. Recent major surgery with bleeding risk.
• C. Hypotension.
• D. Hyperkalemia.

Answer: (A)

Systemic heparin is an anticoagulant used during dialysis to prevent clotting in the extracorporeal circuit, but it increases bleeding risk. Therefore, active bleeding or a very high bleeding risk is a clear contraindication to using systemic heparin during dialysis, because administering anticoagulation would worsen bleeding and could be dangerous. The other scenarios don’t by themselves block heparin use: hypotension is a dialysis-related complication that can be managed, not an absolute contraindication; hyperkalemia is an indication for dialysis rather than a reason to avoid anticoagulation; and while recent major surgery with bleeding risk raises concerns, the explicit active bleeding or very high bleeding risk criterion is the decisive factor.
