- A. Cosyntropin
- B. Sodium bicarbonate

What would the nurse expect the health care provider to order for a client with hypothyroidism?
- A. Levothyroxine sodium
- B. Methimazole
- C. Propranolol
- D. Propylthiouracil
Correct Answer: A
Rationale: Hypothyroidism is treated with thyroid replacement therapy, in the form of desiccated thyroid extract or a synthetic product, such as levothyroxine sodium (Synthroid) or liothyronine sodium (Cytomel). Methimazole and propylthiouracil are antithyroid agents used to treat hyperthyroidism. Propranolol is a beta blocker that can be used to treat hyperthyroidism.
The nurse is teaching a client about the dietary restrictions related to a diagnosis of hyperparathyroidism. What foods should the nurse encourage the client to avoid?
- A. Bananas
- B. Chicken livers
- C. Hamburger
- D. Milk
Correct Answer: D
Rationale: Clients with hyperparathyroidism should use a low-calcium diet (fewer dairy products) and drink at least 3 to 4 L of fluid daily to dilute the urine and prevent renal stones from forming. It is especially important that the client drink fluids before going to bed and periodically throughout the night to avoid concentrated urine. Bananas, chicken livers, and hamburgers do not require avoidance. Milk is the highest in calcium content.
The instructor is teaching a group of students about Simmonds disease. The instructor determines that additional instruction is necessary when the students identify which hormone as being involved?
- A. Growth hormone
- B. Luteinizing hormone
- C. Adrenocorticotropic hormone
- D. Oxytocin
Correct Answer: D
Rationale: Oxytocin is a hormone of the posterior pituitary gland and would not be involved. Simmonds disease affects all hormones of the anterior pituitary: GH (bones and muscles), adrenocorticotropic hormone (ACTH, adrenals), thyroid-stimulating hormone (TSH, thyroid), follicle-stimulating hormone (FSH, ovaries and testes), luteinizing hormone (LH, ovaries), interstitial cell-stimulating hormone (ICSH (LH), testes), and prolactin (breasts).
Which of the following precautions would be most appropriate when caring for a client being treated with radioactive iodine (RAI) for a thyroid tumor?
- A. Administer prescribed corticosteroids carefully.
- B. Handle body fluids carefully.
- C. Monitor the respiratory status.
- D. Administer the prescribed medications at the same time each day.
Correct Answer: B
Rationale: The nurse handles body fluids carefully to prevent spread of contamination. Corticosteroids are not prescribed for thyroid tumor. Monitoring the respiratory status and administering prescribed medicines at the same time each day are unrelated to the care of a client receiving RAI.
Which group of clients should not receive potassium iodide?
- A. Those who are allergic to corticosteroids
- B. Those who are pregnant
- C. Those taking medications such as cough medicines
- D. Those who are allergic to seafood
Correct Answer: D
Rationale: Potassium iodide should not be administered to anyone who is allergic to seafood, which is also high in iodine. Clients who take corticosteroids or cough medicines and those who are pregnant would be appropriate candidates for potassium iodide therapy.
