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
a. Verify the medication three times with the medication administration record.
When administering oral medications, the nurse should verify the medication three times with the medication administration record to ensure that the correct medication is being given to the correct client at the correct time. This is known as the "three checks" and is an important step in preventing medication errors.
Correct Answer is A
Explanation
The correct answer is Choice A.
Choice A rationale: By stating expectations for the client’s behavior, the nurse is addressing the immediate situation and setting clear boundaries.This intervention allows the nurse to assertively communicate with the client, reminding them of appropriate behavior and potentially diffusing the situation1.
Choice B rationale: Requesting security personnel to restrain the client should be a last resort, used only when the client poses a significant risk to themselves or others and all other de-escalation techniques have failed. Restraint can be traumatic and has potential physical and psychological risks.
Choice C rationale: Placing the client in seclusion is another measure that should be used sparingly and only when necessary for the safety of the client or others. It’s important to try less restrictive measures first, such as verbal de-escalation techniques or offering a quiet, private space where the client can regain control.
Choice D rationale: Debriefing staff members about the conflict is an important step, but it should not be the first action. The immediate priority is to ensure the safety of all clients and to de-escalate the situation.
