b. Constipation: Hyperthyroidism is more likely to cause diarrhea or increased bowel movements.

A. Restrict oral fluids to 800 to 1,000 mL/day. B. Maintain an IV of 0.45% sodium chloride. C. Ensure the client receives a 2 g/day sodium diet. D. Administer desmopressin acetate 0.2 mg orally.

Correct Answer is A

Explanation

a. Restrict oral fluids to 800 to 1,000 mL/day: Hyponatremia is a characteristic finding in SIADH, and fluid restriction is a key intervention to correct the imbalance.

b. Maintain an IV of 0.45% sodium chloride: Infusing hypertonic (3%) saline may be indicated in severe cases of hyponatremia, but the initial step is fluid restriction.

c. Ensure the client receives a 2 g/day sodium diet: Dietary sodium restriction is not the primary intervention for SIADH. Fluid restriction is more critical.

d. Administer desmopressin acetate 0.2 mg orally: Desmopressin acetate is an antidiuretic

hormone and would exacerbate the retention of water, further decreasing sodium levels. It is not the appropriate intervention for this client.
