A nurse is caring for a client who has a prescription for warfarin. Which of the following laboratory tests should the nurse monitor?
Triiodothyronine
Blood urea nitrogen
Arterial blood gases
Prothrombin time
The Correct Answer is D
Prothrombin time.
Explanation:
When a client is prescribed warfarin, monitoring the prothrombin time (PT) and the International Normalized Ratio (INR) is crucial. Warfarin is an anticoagulant medication that affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time and INR helps determine the client's blood's ability to clot and the appropriate dosage of warfarin to maintain the desired therapeutic range.
Option a (Triiodothyronine) is a thyroid hormone and is not directly related to warfarin therapy.
Option b (Blood urea nitrogen) is a measure of kidney function and is also not directly related to warfarin therapy.
Option c (Arterial blood gases) is a measure of oxygen and carbon dioxide levels in the blood and is not related to warfarin therapy.
