What is the typical timing for 'heparin reversal' at the end of a hemodialysis session?
-
A
Heparin infusion is stopped 30–60 minutes before the end of treatment to allow clotting to normalize and reduce post-needle-removal bleeding
-
B
Protamine sulfate is administered as heparin infusion continues until the last minute
-
C
Heparin is continued until the needles are removed, then stopped
-
D
Heparin reversal is not performed; the anticoagulant effect wears off on its own over 24 hours
