A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the client's daily warfarin. Which of the following laboratory tests should the nurse plan to report to obtain the prescription for the warfarin?
INR
Fibrinogen level
aPTT
Platelet count
The Correct Answer is A
A. Correct. The International Normalized Ratio (INR) is used to monitor the effectiveness of warfarin therapy, which is commonly prescribed to prevent blood clotting. The INR provides information about the client's prothrombin time (PT) in relation to a standardized value.
B. Fibrinogen level measures clotting potential but is not directly related to warfarin therapy monitoring.
C. Activated Partial Thromboplastin Time (aPTT) is used to monitor other anticoagulants like heparin, not warfarin.
D. Platelet count measures the number of platelets in the blood and is not specifically related to warfarin therapy monitoring.
