Correct Answer is D

Explanation

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.

A. Lowered blood pressure B. Abdominal distention C. Reduced blood glucose D. Weight loss of 2 pounds

Correct Answer is B

Explanation

Choice A rationale
Prednisone is a corticosteroid, and one of its effects can be fluid retention, which can lead to an increase in blood pressure. Therefore, lowered blood pressure is not typically associated with prednisone use.
Choice B rationale
Abdominal distention can be a side effect of prednisone. This can occur due to fluid retention or increased appetite, both of which can be effects of prednisone.
Choice C rationale
Prednisone can actually cause an increase in blood glucose levels, not a reduction. This is because prednisone can stimulate the liver to release extra glucose and can also make body tissues less sensitive to insulin.
Choice D rationale
Weight gain, not weight loss, is a common side effect of prednisone. This can occur due to increased appetite and fluid retention.
