A nurse is caring for a client who has developed a thrombus and is receiving heparin by continuous N infusion. The client asks the nurse how long will it take for the heparin to dissolve the clot. Which of the following responses should the nurse give?

"Heparin does not dissolve clots. It stops new clots from forming"

"Heparin will begin dissolving clots over the next 24 hours

"A pharmacist would be a better fit to answer that question.

"It usually takes heparin at least 3 to 4 days to reach a therapeutic blood level."

Answer and Explanation

The Correct Answer is A

Choice A rationale: Heparin is an anticoagulant that prevents new clots from forming but does not dissolve existing clots23.

Choice B rationale: Heparin does not directly dissolve clots23.

Choice C rationale: While a pharmacist can provide medication information, it is incorrect to say they would be a better fit to answer this question as nurses are trained in medication education23.

Choice D rationale: While it’s true that it takes time for heparin to reach a therapeutic blood level, this statement could be misleading because heparin does not dissolve clots23.

So, the correct answer is Choice A, after analysing all choices.
