A trauma patient arrives in the emergency department via EMS. He is bleeding profusely. A medical alert bracelet indicates that he is on heparin therapy
The nurse will most likely administer which medication that counteracts the action of heparin?
a. Warfarin sodium (Coumadin)
b. Enoxaparin (Lovenox)
c. Protamine sulfate
d. Vitamin K
ANS: C
Protamine sulfate is the antidote to heparin. With the patient's risk of fluid volume deficit as a result of trauma, the primary intervention would be to counteract the effects of heparin to prevent hemorrhage. Warfarin is an anticoagulant and would not counteract hemorrhage. Lovenox is chemically related to heparin and would not counteract hemorrhage. Vitamin K is used to control the bleeding that results from use of warfarin (Coumadin), not heparin.
