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.

Correct Answer is A
Explanation
This is an essential instruction for performing passive ROM exercises safely and effectively. Supporting the extremity above and below each joint helps to prevent injury and provides stability during the exercise. This technique also helps to minimize discomfort and maintain proper alignment of the joint.
Repeat each exercise movement 10 times: This instruction does not provide sufficient guidance on the number of repetitions and may be too general. The number of repetitions will depend on the client's condition and tolerance.
Position the bed at mid-thigh level: This instruction is not necessary for performing passive ROM exercises and may not be feasible in all settings.
Move each joint just past the point of resistance: This instruction can be harmful and may cause injury or pain. The nurse should encourage the family to move the joint gently and smoothly, within the range of motion that is comfortable for the client.
Correct Answer is C
Explanation
A.While monitoring the client's physical condition, including range of motion, is important, it typically needs to be done more frequently than every 60 minutes. The Joint Commission and other regulatory bodies often recommend continuous observation and checks every 15 minutes.
B.Typically, a provider's order for restraints must be obtained immediately or within a very short time frame (often within an hour), not 48 hours. Regulations vary but generally require prompt notification and authorization.
C.Restraints should only be used as a last resort and for the shortest duration possible. The goal is to ensure the client's safety and the safety of others while minimizing the use of restraints. Removing the restraints as soon as the client is calm and no longer a threat to themselves or others is essential to respecting the client's rights and promoting their dignity.
D.Offer the client a nutritious snack every 4 hr.: While providing nutrition and hydration is important, the primary focus immediately after applying restraints should be on the client's safety and the frequent assessment of their condition. Offering a snack every 4 hours is not the immediate priority in this context.
