A client with syndrome of inappropriate antidiuretic hormone (SIADH) is severely hyponatremic. What IV fluids would the nurse anticipate administering to this client?
- A. 3% hypertonic sodium chloride solution
- B. Lactated Ringer's solution
- C. 5% dextrose in water
- D. 0.9% sodium chloride solution
Correct Answer: A
Rationale: Severe hyponatremia is treated with IV administration of a 3% hypertonic sodium chloride solution. The other answers will not provide the amount of sodium required to correct the hyponatremia.

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.
What intervention can the nurse encourage the client with diabetes insipidus to do in order to control thirst and compensate for urine loss?
- A. Come to the clinic for IV fluid therapy daily.
- B. Limit the fluid intake at night.
- C. Consume adequate amounts of fluid.
- D. Weigh daily.
Correct Answer: C
Rationale: The nurse teaches the client to consume sufficient fluid to control thirst and to compensate for urine loss. The client will not be required to come in daily for IV fluid therapy. The client should not limit fluid intake at night if thirst is present. Weighing daily will not control thirst or compensate for urine loss.
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.
The nurse is caring for a client who has syndrome of inappropriate antidiuretic hormone (SIADH). The nurse notices that the client has become confused and extremely short of breath, and crackles are heard when lungs are auscultated. What is the first action by the nurse?
- A. Administer a diuretic.
- B. Notify the physician.
- C. Lay the client flat.
- D. Suction the client.
Correct Answer: B
Rationale: The nurse closely monitors fluid intake and output and vital signs. The nurse carefully assesses LOC and immediately reports any changes to the physician. The nurse checks closely for signs of fluid overload (confusion, dyspnea, pulmonary congestion, hypertension) and hyponatremia (weakness, muscle cramps, anorexia, nausea, diarrhea, irritability, headache, weight gain without edema). Laying the client flat would increase the shortness of breath and would deoxygenate the client. The nurse cannot administer a diuretic without the physician's order. Suctioning of the client will not clear the airway at this time.
What life-threatening outcome should the nurse monitor for in a client who is not compliant with taking prescribed antithyroid medication?
- A. Thyrotoxic crisis
- B. Myxedema coma
- C. Diabetes insipidus
- D. Syndrome of inappropriate antidiuretic hormone secretion
Correct Answer: A
Rationale: Thyrotoxic crisis, an abrupt and life-threatening form of hyperthyroidism, is thought to be triggered by extreme stress, infection, diabetic ketoacidosis, trauma, toxemia of pregnancy, or manipulation of a hyperactive thyroid gland during surgery or physical examination. Although rare, this condition may occur in clients with undiagnosed or inadequately treated hyperthyroidism. Myxedema coma is associated with hypothyroidism. Diabetes insipidus (DI) and syndrome of inappropriate antidiuretic hormone secretion (SIADH) clinical manifestations do not correlate with medication taken for hyperthyroidism.
