Question 1 of 5
A nurse is caring for a client who is diagnosed with a deep vein thrombosis (DVT) and is receiving heparin. The client asks the nurse how long it will take for the heparin to dissolve the clot. Which of the following responses should the nurse give?
Correct Answer: C
Rationale:
Correct Answer: C. Heparin does not dissolve clots. It stops new clots from forming.
Rationale:
1. Heparin is an anticoagulant that works by inhibiting clot formation, not dissolving existing clots.
2. The client already has a DVT, so heparin's primary role is to prevent the clot from getting larger and prevent new clots from forming.
3.
To dissolve an existing clot, thrombolytic therapy such as alteplase is typically used, not heparin.
4. Monitoring PT/INR levels (
Choice
A) is more relevant for warfarin therapy, not heparin.
5. It takes heparin a few hours to reach therapeutic levels, not 2 to 3 days (
Choice
B).
6. Clots do not immediately dissolve after the first dose of heparin (
Choice
D).
