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 C
Explanation
Iron supplementation commonly causes constipation, which is due to the iron's effect of slowing down bowel movements and increasing water absorption in the intestines.
Dry mouth is not a common adverse effect of iron supplementation. It is more commonly associated with medications that can cause xerostomia (dry mouth), such as certain antihistamines or anticholinergic drugs.
Tinnitus, a perception of ringing or noise in the ears, is not typically associated with iron supplementation. Tinnitus can be caused by various factors, such as exposure to loud noises, ear infections, or certain medications, but it is not directly related to iron supplementation.
Hematuria, the presence of blood in the urine, is not a common adverse effect of iron supplementation. It can be caused by various conditions affecting the urinary system, such as urinary tract infections, kidney stones, or bladder issues, but it is not directly related to iron supplementation.
Correct Answer is C
Explanation
Choice A Reason:
Blaming the assistive personnel without additional information or evidence may not be appropriate and should be investigated further.
Choice B Reason:
Mentioning that an incident report has been completed and sent to risk management is important for institutional record-keeping and follow-up but does not provide details about the incident itself.
Choice C Reason:
"Client stated, 'I lost my balance and fell when I got out of bed to go to the bathroom'." In the documentation of a client fall, it is important to include the client's own account of the incident, as this can provide valuable information about the circumstances surrounding the fall. Including direct quotes or statements from the client helps to accurately capture their perspective and can be useful for assessing the root causes of the fall and developing appropriate interventions to prevent future falls.
Choice D Reason:
Documenting that the client does not appear to have any injuries is relevant but does not provide information about the circumstances of the fall, which is important for a comprehensive understanding of the event.
