Question 1 of 5
A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the cient's daily warfarin. Which of the following laboratory tests should the nurse plan to report to obtain the prescription for the warfarin?
Correct Answer: C
Rationale: The correct answer is C: INR. The International Normalized Ratio (INR) is used to monitor and adjust the dosage of warfarin, an anticoagulant medication. A nurse needs to report the INR level to the provider to determine if the current dosage of warfarin is effective in preventing blood clots. A higher INR indicates a longer time it takes for blood to clot, meaning the warfarin dosage might need adjustment.
Incorrect choices:
A: Fibrinogen level - Fibrinogen is a protein involved in blood clotting but is not specific for monitoring warfarin therapy.
B: aPTT - Activated Partial Thromboplastin Time (aPTT) is used to monitor heparin therapy, not warfarin.
D: Platelet count - Platelet count measures the number of platelets in the blood and is not directly related to warfarin therapy.
Overall, the INR is the most
