A nurse is preparing to administer a scheduled dose of warfarin to a client. Which of the following laboratory tests should the nurse review prior to administration?
PT
Total iron-binding capacity
WBC
PTT
The Correct Answer is A
PT measures the time it takes for blood to clot, and it is particularly relevant for clients taking warfarin because warfarin works by inhibiting the synthesis of certain clotting factors, including factors II, VII, IX, and X, which are involved in the PT pathway. Monitoring PT levels helps ensure that the client is receiving an appropriate dose of warfarin to prevent clot formation without causing excessive bleeding.
B. Total iron-binding capacity (TIBC) is a test used to assess iron levels in the blood and is unrelated to warfarin therapy.
C. WBC (White Blood Cell count) is a test used to assess the number of white blood cells in the blood and is unrelated to warfarin therapy.
D. PTT (Partial Thromboplastin Time) is a test used to evaluate the intrinsic and common pathways of the coagulation cascade. It is used in the monitoring of heparin anticoagulant therapy. It is not typically used to monitor warfarin therapy
