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
Dry, itchy skin is a common concern in older adults, especially during the winter months or in dry environments. Increasing the humidity in the client's environment can help alleviate dryness and itching. Placing a humidifier in the client's room will add moisture to the air and help prevent excessive drying of the skin. It is important to ensure that the humidifier is clean and well-maintained to avoid the growth of bacteria or mould.
Encouraging the client to bathe frequently may further dry out the skin, so it is not recommended. Similarly, applying powder to the skin may exacerbate dryness and should be avoided. Adding moisturizing oil to the bath water may provide temporary relief, but a humidifier will have a more consistent and long-lasting effect on the client's environment.
Correct Answer is D
Explanation
A.Using hydrogen peroxide for wound cleaning is not recommended as it can cause tissue damage and delay healing.
B.Burn dressings should typically be changed more frequently, often at least once per day, depending on the type and severity of the burn and the type of dressing used.Delaying dressing changes could increase the risk of infection.
C.In wound care, the nurse should cleanse the least contaminated wounds first to prevent spreading microorganisms from more contaminated areas to cleaner areas. This reduces the risk of cross-contamination and infection. For burns, starting with the cleanest areas ensures a safer wound management process.
D.Applying dressings with sterile gloves is essential to maintain a sterile environment and reduce the risk of infection, especially in clients with burns who are at high risk for infection due to compromised skin integrity.
