A nurse is monitoring a client who received desmopressin (DDAVP) to treat diabetes insipidus. Which of the following findings indicates effectiveness of the medication?
Increased heart rate
Increased blood pressure
Serum sodium 150 mEq/L (136-145)
Urine specific gravity 1.015 (1.005 - 1.030)
The Correct Answer is D
A. Increased heart rate: An increased heart rate may indicate dehydration or hypovolemia, which would suggest desmopressin is ineffective in managing diabetes insipidus.
B. Increased blood pressure: Desmopressin might increase blood pressure slightly, but this is not a direct indicator of its effectiveness in controlling diabetes insipidus.
C. Serum sodium 150 mEq/L (136-145): Elevated sodium levels indicate persistent dehydration or insufficient control of fluid balance, suggesting the treatment is ineffective.
D. Urine specific gravity 1.015 (1.005 - 1.030): A normalized urine specific gravity indicates that desmopressin is effectively concentrating the urine, a key goal in managing diabetes insipidus.

Correct Answer is D
Explanation
A. "You are retaining a lot of sodium and potassium, and that causes you to gain water weight.": SIADH involves dilutional hyponatremia, not retention of sodium and potassium.
B. "Your kidneys are not working correctly, so they can't get rid of extra water from your system.": SIADH results from excessive secretion of antidiuretic hormone (ADH), not kidney dysfunction.
C. "The syndrome causes an increase in appetite. As soon as you are effectively treated, the weight should drop back to normal for you.": SIADH causes water retention, not increased appetite.
D. "You have too much of a hormone in your system that causes you to retain water. The extra 10 pounds is likely water weight.": This accurately explains that excess ADH leads to water retention, causing weight gain.
