Answer to Question 1

2

Rationale 1: Potassium chloride does not reverse the effects of heparin.
Rationale 2: Vitamin K is used to reverse the effects of warfarin. Recommended post-treatment INR values range from 2 to 4.5.
Rationale 3: Desirudin (Iprivask) is a newer antithrombin.
Rationale 4: Protamine sulfate is used to reverse heparin.

Global Rationale: Vitamin K is used to reverse the effects of warfarin. Recommended post-treatment INR values range from 2 to 4.5. Potassium chloride does not reverse the effects of heparin. Desirudin (Iprivask) is a newer antithrombin. Protamine sulfate is used to reverse heparin.

Answer to Question 2

4

Rationale 1: Vitamin K reverses the effect of warfarin (Coumadin).
Rationale 2: Desirudin (Iprivask) is a newer antithrombin medication that is given subcutaneously 15 minutes prior to hip replacement surgery for prophylaxis of DVT.
Rationale 3: Potassium chloride 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.
