الإجابة: C. After ≥5 days of overlap and once the INR is therapeutic
Warfarin's effect takes 4-5 days to develop, so heparin/LMWH is continued as a bridge (overlap of several days) and stopped only once the INR is therapeutic. Stopping at 24 hours, at warfarin start, after 2 days, or at INR 1.5 leaves the patient under-anticoagulated.

D
ليش غلط
Heparin must continue for at least 4 days after starting warfarin, and stopping depends on a therapeutic INR, not on a fixed 2 days.

E
ليش غلط
Heparin is stopped when the INR is therapeutic (2 to 3 in most cases), not when it first exceeds 1.5.
