A nurse is reinforcing teaching about foot care with a client who has type 2 diabetes mellitus.

Which of the following statements by the client indicates an understanding of the teaching?

Explanation B.Triiodothyronine

Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4). It is converted to triiodothyronine (T3), the active form of the thyroid hormone, in the body. Monitoring the levels of triiodothyronine (T3) can help assess the effectiveness of levothyroxine therapy and ensure that the client's thyroid hormone levels are within the desired therapeutic range.

Serum potassium levels in (option A) should not be monitored because they are not directly affected by levothyroxine. However, imbalances in electrolytes can occur in some individuals with thyroid disorders. Electrolyte levels may be monitored, but it is not the primary focus of monitoring for levothyroxine therapy.

Blood urea nitrogen (BUN) in (option C) should not be monitored because it is a test used to assess kidney function and is not directly related to monitoring levothyroxine therapy.

Prothrombin time (PT) in (option D) should not be monitored because it is a test used to evaluate the clotting function of the blood and is not specifically related to monitoring levothyroxine therapy.

1. "Your health care surrogate will make decisions on your behalf if you are unable": This statement is correct. A health care surrogate, also known as a health care proxy or durable power of attorney for health care, is an individual designated by the client to make medical decisions on their behalf if they become unable to make decisions for themselves. It is important for the client to choose someone they trust and who understands their values and wishes.
2. "You will need an attorney to appoint a health care surrogate": This statement is not necessarily true. While involving an attorney can be helpful, it is not always required to appoint a health care surrogate. In many jurisdictions, a legally valid health care surrogate designation can be made through a simple document or form provided by the hospital or a local government office. It is important to check the specific legal requirements in the client's jurisdiction.
3. "You should appoint a family member as your health care surrogate": This statement is a subjective recommendation and may not be applicable to all individuals. The decision of whom to appoint as a health care surrogate should be based on the client's personal preferences and the individual's ability to make informed decisions according to the client's wishes. While a family member is often chosen, it is not a requirement, and the client may choose a close friend, partner, or anyone else they trust to fulfill this role.
4. "Once you have completed a living will, it cannot be changed": This statement is incorrect. A living will, which is a type of advanced directive, can be changed or revoked at any time by the client as long as they are competent to do so. It is important for the client to review and update their living will periodically to ensure that it reflects their current wishes regarding medical care and treatment.
