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
Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Therefore, it is important to monitor the client's clotting ability to ensure that the medication is working properly and not causing any adverse effects. The laboratory test that is used to monitor warfarin therapy is the prothrombin time (PT), which measures the time it takes for the blood to clot. The nurse should monitor the client's PT regularly and adjust the dosage of warfarin as necessary to maintain the 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.

Correct Answer is A
Explanation
A nurse caring for a client who is 2 days postoperative following an above-the-knee amputation should encourage the client to use the overbed trapeze. This will promote independence and mobility by allowing the client to reposition themselves in bed and perform upper body exercises.
Maintaining abduction of the client's residual limb with a pillow can help prevent contractures, but it does not directly promote mobility.
Cautioning the client to avoid a prone position while in bed is appropriate to prevent pressure injuries and promote healing, but it also does not directly promote mobility.
Keeping a loose, absorbent dressing over the client's surgical site is important for infection control but does not promote mobility.
