A patient has been prescribed radioactive iodine in preparation for a total thyroidectomy due to thyroid cancer. What advice about taking the medication should the nurse provide?

Choice A rationale
While continuous pulse oximetry can provide useful information about a patient’s oxygen saturation levels, it is not the most crucial step before administering amphotericin B. Amphotericin B is an antifungal medication used to treat serious, potentially life-threatening fungal infections. It does not directly affect oxygen saturation levels.
Choice B rationale
The rate at which amphotericin B is administered can be important, as the medication must be given slowly through an IV infusion, which can take from 2 to 6 hours to complete. However, setting the IV pump to deliver the medication over a specific span of time is not the most crucial step before administration.
Choice C rationale
Continuous cardiac monitoring can be important in certain situations, but it is not the most crucial step before administering amphotericin B. While amphotericin B can cause some side effects related to the heart, such as changes in heart rate or blood pressure, these are not typically the primary concerns before administration.
Choice D rationale
Evaluating the patient’s sodium and calcium levels is the most crucial step before administering amphotericin B. Amphotericin B can cause changes in electrolyte levels, including sodium and calcium. Monitoring these levels can help prevent potential complications, making this the most crucial step before administration.

Choice A rationale
It is not advisable for a patient to discontinue radioactive iodine therapy at any time if they feel uncomfortable. Radioactive iodine therapy is a safe and effective treatment for certain types of thyroid cancer. Discontinuing the medication without medical advice could lead to ineffective treatment.
Choice B rationale
Increasing the consumption of iodine-rich foods is not necessary when a patient is prescribed radioactive iodine. The body’s thyroid cells absorb the radioactive iodine, which then destroys the cells. Consuming additional iodine would not enhance this process.
Choice C rationale
Using a straw to drink the medication is not necessary. Radioactive iodine is usually given in pill form, not as a liquid. Therefore, there is no risk of it staining the patient’s teeth.
Choice D rationale
This statement is correct. After a total thyroidectomy, the patient will no longer have thyroid tissue that can produce thyroid hormones. Therefore, the radioactive iodine will not eliminate the need for thyroid hormone replacement.
