A nurse is assisting in developing a list of internet sites for clients to obtain valid health information. When evaluating internet resources, which of the following findings indicates the information likely contains credible medical information?

During an intravenous pyelogram (IVP), a contrast dye is injected into the client's veins, and X-ray images are taken to visualize the urinary tract. The dye used in an IVP can cause a warming or flushing sensation as it circulates through the body. The client's statement indicates an understanding of this common sensation associated with the procedure.

"I can have a meal up to 2 hours before the procedure": This statement is incorrect. Typically, for an IVP, the client is required to have an empty stomach before the procedure to ensure accurate imaging results. The client should follow the specific instructions provided by their healthcare provider regarding fasting before the procedure.

"I do not need to sign a consent form before this procedure": This statement is incorrect. Informed consent is required for most medical procedures, including an IVP. The client should sign a consent form after receiving all the necessary information about the procedure, its risks, and benefits.

"I should limit my fluid intake for 2 days after the procedure": This statement is incorrect. After an IVP, it is generally advised to increase fluid intake to help flush out the contrast dye from the body and prevent potential complications. The client should follow the specific instructions provided by their healthcare provider regarding post-procedure fluid intake.

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.
