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. "I will use Lantus insulin immediately before each meal.": Lantus (insulin glargine) is a long-acting insulin designed to provide basal glucose control and should not be used before meals.
B. "I should shake the bottle of insulin before withdrawing the medication.": Insulin should be gently rolled, not shaken, to avoid air bubbles or degradation of the insulin.
C. "Insulin injected into the thigh is the most rapidly absorbed.": The abdomen has the fastest absorption rate for insulin injections, followed by the arm, thigh, and buttocks.
D. "Unopened vials of insulin should be kept in my refrigerator.": Insulin should be refrigerated until opened to maintain potency. Once opened, it can be kept at room temperature for up to 28 days.
Correct Answer is ["1"]
Explanation
Both regular insulin and NPH insulin can be mixed in one syringe, as they are compatible. The nurse should draw up regular insulin first (14 units) and then NPH insulin (28 units) to ensure accuracy. Only 1 syringe is required.
