A patient receiving unfractionated heparin develops a sudden fall in platelet count and a new painful, swollen leg. Which complication should the nurse suspect?
Correct answer: B. Heparin-induced thrombocytopenia
- A. Vitamin K deficiency
- B. Heparin-induced thrombocytopenia
- C. Warfarin-related skin necrosis
- D. Aspirin-induced gastric irritation
Explanation
A falling platelet count with new thrombosis during heparin therapy suggests heparin-induced thrombocytopenia. The nurse should stop and urgently report the suspected reaction because it can cause serious clotting despite the low platelet count.
