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.

Correct Answer is D
Explanation
A) Coiling the tubing on the bed above the collection bag is incorrect because it can cause urine to flow back into the bladder, increasing the risk of infection and compromising the effectiveness of the drainage system. The tubing should be kept below the level of the bladder to ensure proper drainage.
B) Instructing the client to hold the drainage bag at waist height when ambulating is incorrect because the drainage bag should always be kept below the level of the bladder to prevent urine from flowing back into the bladder, which could lead to a urinary tract infection (UTI).
C) Collecting a sterile specimen from the urinary drainage bag is incorrect because urine in the drainage bag is not considered sterile. If a sterile specimen is needed, it should be obtained by cleaning the catheter's sampling port with an antiseptic solution and withdrawing urine directly from the port using a sterile syringe.
D) Securing the tubing with adhesive tape to the lower abdomen is correct because it helps prevent accidental pulling or tugging on the catheter, which could cause discomfort or dislodgement. Properly securing the tubing also helps maintain a continuous flow of urine and reduces the risk of infection.
Correct Answer is ["A","D","E","F"]
Explanation
To decrease the risks for a urinary tract infection for this client, the nurse should take several actions. The nurse should encourage the client to drink 3,000 mL of fluid daily to help flush bacteria out of the urinary tract¹. The nurse should also empty the drainage bag when it is half-full to prevent bacterial growth¹.
Additionally, the nurse should review the need for the indwelling urinary catheter daily and use soap and water to provide perineal care¹.
