A nurse is caring for a client who has diabetes insipidus and is receiving vasopressin. The nurse should identify which of the following findings as an indication that the medication is working? A decrease in...
urine output
specific gravity
blood glucose
blood pressure
The Correct Answer is A
A. Urine output is correct. Diabetes insipidus (DI) causes excessive urine output due to a deficiency in antidiuretic hormone (ADH). Vasopressin acts as a synthetic ADH, helping the kidneys retain water. A decrease in urine output indicates the medication is effective.
B. Specific gravity would actually increase if the medication is working, as the urine becomes more concentrated. A decrease in specific gravity would indicate continued dilute urine, suggesting the medication is not effective.
C. Blood glucose is not typically affected by vasopressin or directly related to diabetes insipidus, which is different from diabetes mellitus.
D. Blood pressure might slightly increase due to vasopressin's vasoconstrictive effects, but this is not the primary indicator that the medication is working for diabetes insipidus.

- Ordered dose = 1300 units/hr
- Available concentration = 25,000 units in 500 mL
Step 2: Calculate concentration of heparin per mL
25,000 units ÷ 500 mL = 50 units/mL
Step 3: Calculate the mL/hr to deliver 1300 units/hr
1300 units ÷ 50 units/mL = 26 mL/hr
Answer: 26 mL/hr
