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:
Wiping from the outer to the inner canthus is not necessary and may cause contamination.
Choice B Reason:
Apply pressure to the lacrimal punctum after administering the drops. After administering eye drops to a child, it is important to gently apply pressure to the lacrimal punctum (located in the inner corner of the eye) for about 1-2 minutes. This helps prevent systemic absorption of the medication and reduces the risk of it going into the nasopharynx and digestive system. The other options are not recommended:
Choice C Reason:
Positioning the child side-lying is not typically required for administering eye drops.
Choice D Reason:
Rinsing the eye with normal saline before administering the drops is not a standard practice and is not recommended unless there is a specific reason to do so, such as eye irritation or foreign body removal.
Correct Answer is C
Explanation
Choice A Reason:
"Have you tried leaving your house just once per day?" This response assumes a potential solution without fully understanding the client's feelings. It doesn't encourage open discussion or exploration of the client's anxiety.
Choice B Reason:
"Have you thought about moving to a new neighborhood?" This response jumps to a significant life change as a solution without exploring the client's current situation and emotions. It may not be a practical or necessary step.
Choice C Reason:
"Let's discuss how you feel when you leave your house." This response is an open and therapeutic approach that encourages the client to express their feelings and thoughts about the situation. It allows the nurse to gather more information and better understand the client's anxiety related to leaving the house. The other options do not facilitate open communication or exploration of the client's feelings.
Choice D Reason:
"Tell me why you have developed an aversion to leaving your house." While this response is more open-ended, it phrases the question in a somewhat confrontational manner, which might make the client defensive. The previous response ("Let's discuss how you feel when you leave your house") is gentler and inviting.
