The correct answer to the question is: A. PT/INR Explanation: 1. Warfarin is a medication commonly prescribed as an anticoagulant (blood thinner). 2. PT (Prothrombin Time) and INR (International Normalized Ratio) tests are used to monitor the effectiveness of anticoagulant medications like warfarin. 3. Warfarin works by inhibiting the production of certain clotting factors in the liver, affecting the clotting time of blood. 4. Monitoring PT/INR levels helps healthcare providers ensure that the patient is receiving the appropriate dosage of warfarin to prevent blood clots or excessive bleeding. 5. Therefore, the results of PT/INR tests are directly impacted by warfarin medication, making it essential for the phlebotomy technician to be aware of the patient's medication to interpret the test results accurately. In summary, when a patient taking warfarin informs the phlebotomy technician, they should identify that the results of the PT/INR test will be affected by this medication. This knowledge is crucial for proper patient care and accurate interpretation of test results.

Warfarin is an anticoagulant medication that works by inhibiting the clotting factors in the blood, affecting how long it takes for blood to clot. The PT/INR test measures the clotting ability of the blood and is commonly used to monitor patients who are taking anticoagulants like warfarin.
