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.

The client who had a radical mastectomy 36 hours ago and has a surgical drain is the most stable among the given options and is further along in the recovery process. This client may be ready for discharge with appropriate follow-up care instructions, and their bed can be utilized for the incoming clients who were injured in a tornado.
The client who had a cerebrovascular accident 8 hours ago and received thrombolytic therapy requires close monitoring and assessment for complications, such as bleeding or changes in neurological status.
The client with cervical cancer and an internal radioactive implant requires specific precautions and monitoring to ensure radiation safety and to manage any potential side effects or complications.
The client who had a lobectomy and has a chest tube drainage system needs continued monitoring of respiratory status and drainage, as well as close observation for any signs of complications or worsening condition.
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.
