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
d. Prothrombin time.
Explanation:
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 B
Explanation
Choice A Reason:
A. Changing the appliance on a new colostomy requires specialized knowledge of ostomy care and assessment, including assessing stoma health and proper technique.
Choice B Reason:
This is an appropriate task to delegate to an AP. APs are trained to perform basic tasks like catheter care under the supervision of a nurse.
Choice C Reason
Demonstrating how to use an incentive spirometer involves patient education and assessment of the patient's ability to perform the procedure correctly, which requires clinical judgment and teaching skills and should not be delegated to an AP.
Choice D Reason:
This task involves assessing the wound, which requires clinical judgment and should be done by a nurse, not an AP.
Correct Answer is A
Explanation
Choice A Reason:
Raises all four side-rails on the client's bed .The nurse should intervene when the assistive personnel (AP) raises all four side-rails on the client's bed. Using all four side-rails on the bed is considered a restraint, and its use should be avoided unless there is a specific clinical indication and an order from the healthcare provider. Restraints should only be used when less restrictive alternatives have been attempted and are not successful in preventing the client from falling.
Choice B Reason:
Assisting the client to the bathroom every 2 hours is a proactive measure to help the client maintain their continence and reduce the risk of falls associated with trying to get to the bathroom independently.
Choice C Reason:
Clearing furniture from the path leading to the bathroom helps create a safe and unobstructed environment for the client to navigate.
Choice D Reason:
Locking the wheels on the client's bed is an appropriate safety measure to prevent the bed from moving while the client is getting in or out.
