Question 1 of 5
A client with a large goiter is scheduled for a subtotal thyroidectomy to treat thyrotoxicosis. Saturated solution of potassium iodide (SSKI) is prescribed preoperatively for the client. The primary reason for using this drug is that it helps:
Correct Answer: B
Rationale: SSKI reduces the vascularity of the thyroid gland, making surgery safer by decreasing the risk of bleeding. It does not primarily affect exophthalmos, thyroxine storage, or excretion.
Question 2 of 5
After treatment with radioactive iodine (RAI) in the form of sodium iodide 131I, the nurse teaches the client to:
Correct Answer: C
Rationale: RAI often destroys enough thyroid tissue to cause hypothyroidism, requiring lifelong thyroxine replacement. Monitoring for hyperthyroidism is unnecessary post-treatment, and rest or assessing for hypertension/tachycardia are not primary concerns.
Question 3 of 5
A client is to receive glargine (Lantus) insulin in addition to a dose of aspart (NovoLog). When the nurse checks the blood glucose level at the bedside, it is greater than 200 mg/dL. How should the nurse administer the insulins?
Correct Answer: D
Rationale: Glargine and aspart insulins cannot be mixed. They should be drawn up in separate syringes to maintain their distinct actions (long-acting vs. rapid-acting). Shaking or rolling is inappropriate for glargine, which is clear.
Question 4 of 5
The client with type 1 diabetes mellitus is taught to take NPH insulin at 5 p.m. each day. The client should be instructed that the greatest risk of hypoglycemia will occur at about what time?
Correct Answer: D
Rationale: NPH insulin peaks 4–12 hours after administration (around 9 p.m. to 5 a.m.), with the greatest hypoglycemia risk overnight, such as at 1 a.m.
Question 5 of 5
A client expresses concern about how a hypophysectomy will affect his sexual function. Which of the following statements provides the most accurate information about the physiologic effects of hypophysectomy?
Correct Answer: D
Rationale: Hypophysectomy may disrupt pituitary hormone production, including those affecting sexual function. Exogenous hormones (e.g., testosterone) are often needed to restore erectile function.
