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.

Explanation
During a mass casualty event, it is crucial for the nurse to assess and determine the acuity level (severity) and number of casualties who will be arriving at the healthcare facility. This information helps in planning and organizing resources, triaging patients based on their needs, and ensuring that appropriate care is provided to those who require immediate attention.
Delegating tasks to emergency health care specialists is a role that may be performed by a nurse in a leadership or supervisory position. However, the immediate priority for the nurse is to assess and triage incoming casualties.
Providing informational updates to members of the media is usually handled by designated spokespersons or communication specialists within the healthcare facility or incident command system. Nurses are primarily focused on patient care and should not be responsible for media communication during a mass casualty event.
Assisting in discharging stable clients to home is not directly related to the immediate response and care of casualties from a mass casualty event. The nurse's focus in such situations is primarily on the management of the incoming casualties and ensuring the availability of resources and care for those who require immediate attention.
Correct Answer is B
Explanation
Stomatitis is an inflammation of the oral mucosa, which can cause pain, discomfort, and difficulty eating. To manage stomatitis, clients should consume soft, bland foods that are easy to chew and swallow, such as cooked vegetables, mashed potatoes, and oatmeal.
Acidic, spicy, or crunchy foods should be avoided. Using lemon glycerin swabs can irritate the oral mucosa, so they should not be used.
Mouthwashes containing alcohol can cause further irritation, so they should also be avoided. Eating foods high in vitamin B12 can be helpful for preventing stomatitis, but it is not an appropriate intervention for managing an existing case of stomatitis.
