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.

Explanation
a. Clean the stoma using an inward to outward circular motion.
When providing tracheostomy care, the nurse should clean the stoma using an inward to outward circular motion to remove any secretions or debris. It is important to avoid using excessive force or pressure, which can cause trauma to the stoma. Cleansing the inner cannula with isopropyl alcohol may be appropriate for some clients, but it is important to follow the healthcare provider's orders regarding inner cannula care.
When securing the tracheostomy ties, the nurse should ensure that there is enough space for two fingers, not three. Finally, the nurse should prepare sterile supplies before removing the inner cannula to ensure that they are readily available and reduce the risk of infection.
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.
