A nurse is providing discharge teaching about warfarin to a client who has deep- vein thrombosis.
The nurse should instruct the client to obtain which of the following laboratory tests monthly?
Platelet count.
aPTT.
Fibrinogen.
INR.
The Correct Answer is D
A client who has deep-vein thrombosis and is taking warfarin should obtain an International Normalized Ratio (INR) test monthly.
This blood test measures how fast the blood clots and helps the healthcare provider determine if the client is taking the right dose of warfarin to keep them safe from bleeding and making clots.
Choice A is wrong because Platelet count, is not the correct answer because it measures the number of platelets in the blood and is not specifically related to warfarin therapy.
Choice B is wrong because aPTT, is not the correct answer because it measures the time it takes for blood to clot and is used to monitor heparin therapy, not warfarin therapy.
Choice C is wrong because Fibrinogen, is not the correct answer because it measures the amount of fibrinogen in the blood and is not specifically related to warfarin therapy.
