A client is receiving heparin (Heplock) therapy, and serious hemorrhage occurs. Which medication should the nurse administer to reverse the effects of heparin (Heplock)?
1. Vitamin K
2. Desirudin (Iprivask)
3. Potassium
4. Protamine sulfate
Correct Answer: 4
Rationale 1: Vitamin K is incorrect because it reverses the effect of warfarin (Coumadin).
Rationale 2: Desirudin (Iprivask) is incorrect because this medication is a newer antithrombin medication that is given subcutaneously 15 minutes prior to hip replacement surgery for prophylaxis of DVT.
Rationale 3: Potassium is incorrect because it does not reverse the effects of heparin.
Rationale 4: If serious hemorrhage occurs, a specific blocker, protamine sulfate, may be administered to neutralize the anticoagulant activity of heparin. Protamine sulfate has an onset time of 5 minutes, and is also a blocker of the LMWHs.
