Question 1 of 5
A nurse is caring for a client who has deep vein thrombosis. The client has been receiving IV heparin for the past 5 days and now has a new prescription for oral warfarin in addition to the heparin. The client asks the nurse if both medications are necessary. Which of the following is an appropriate response by the nurse?
Correct Answer: Heparin and warfarin prevent clot growth, not dissolution. No enhancement occurs. Heparin bridges until warfarin's therapeutic level is reached, typically 3 days.
Rationale:
Correct Answer: D. "Heparin will be continued until the warfarin reaches a therapeutic level."
Rationale:
1. Heparin and warfarin work differently: Heparin prevents new clots, while warfarin stabilizes existing clots.
2. Transition period: Heparin is continued initially to prevent clotting while warfarin reaches its full anticoagulant effect.
3. Therapeutic level: Warfarin takes time to reach its target level for optimal clot prevention.
4. No clot dissolution: Neither heparin nor warfarin directly dissolve clots; they prevent further clot formation.
Summary of other choices:
A: Incorrect. Misleading information about clot dissolution.
B: Incorrect. Unnecessary escalation without clarifying the situation.
C: Incorrect. Misconception about the relationship between heparin and warfarin.
