A nurse is preparing discharge teaching for a client who will be going home on warfarin. Which of these client statements indicates the need for further instruction?
"I should avoid alcohol and herbal remedies while I am taking warfarin."
"If I notice signs of bleeding I will stop taking warfarin and follow up with my doctor in a week."
"I should be consistent with my intake of leafy greens while I am taking warfarin."
"I should have my international normalized ratio (INR) checked regularly while I am on warfarin."
The Correct Answer is B
a) Avoiding alcohol and herbal remedies is a correct instruction because they can interact with warfarin and increase the risk of bleeding.
b) Stopping warfarin abruptly without healthcare provider guidance can be dangerous and increase the risk of thrombosis. Signs of bleeding should be reported promptly to the healthcare provider for appropriate management.
c) Being consistent with the intake of leafy greens is important to maintain a stable INR, as these foods contain vitamin K, which can interfere with warfarin.
d) Regular INR monitoring is essential to ensure that the client is within the therapeutic range and to make adjustments to the warfarin dosage if necessary.
