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:
Discontinuing music therapy when the client is no longer responsive is not necessary. Music therapy can continue to provide comfort and support even if the client is not responsive.
Choice B Reason:
"Music will distract my husband's awareness of the pain." This statement indicates an understanding of the potential benefits of music therapy for pain management. Music therapy can help distract individuals from their pain, reduce anxiety and stress, and enhance relaxation. It may not eliminate pain entirely but can provide a valuable complementary approach to pain management in hospice care.
Choice C Reason:
Playing music is not typically used to increase alertness in the context of pain management. Instead, it is often used to promote relaxation and reduce pain-related distress.
Choice D Reason:
Music therapy is not a replacement for medication in managing pain, especially breakthrough pain. Medication and music therapy can be used together as part of a comprehensive pain management plan in hospice care.
