A nurse is caring for a client who has diabetes insipidus and is receiving desmopressin by intermittent IV bolus. Which of the following manifestations should the nurse identify as an indication of a therapeutic response to the medication?

Increase in serum sodium

Decrease in urine output

Increase in heart rate

Decrease in blood pressure

Answer and Explanation

The Correct Answer is B

A.   Increase in serum sodium: Desmopressin, a synthetic form of vasopressin, works to decrease urine output and increase water reabsorption in the kidneys. Therefore, a therapeutic response to desmopressin would not result in an increase in serum sodium; rather, it would aim to normalize serum sodium levels by reducing excessive urine output.
B.   Decrease in urine output: The primary therapeutic goal of desmopressin in the treatment of diabetes insipidus is to decrease urine output by increasing water reabsorption in the kidneys. Therefore, a decrease in urine output would indicate a positive response to the medication.
C.   Increase in heart rate: Desmopressin primarily affects kidney function by increasing water reabsorption and does not typically have a direct effect on heart rate. Therefore, an increase in heart rate would not be a manifestation of a therapeutic response to desmopressin.
D.   Decrease in blood pressure: Desmopressin works to increase water reabsorption in the kidneys and does not typically cause significant changes in blood pressure. Therefore, a decrease in blood pressure would not be a manifestation of a therapeutic response to desmopressin.

Correct Answer is ["19"]

Explanation

Drip rate (gtt/min) = (Volume to be infused in mL × Drop factor) ÷ Time of infusion in minutes

Given:

Volume to be infused = 350 mL Drop factor = 10 gtt/mL
Time of infusion = 3 hours = 180 minutes

Plugging these values into the formula:

Drip rate = (350 mL × 10 gtt/mL) ÷ 180 min Drip rate ≈ (3500 gtt) ÷ 180 min
Drip rate ≈ 19.4 gtt/min

Rounding to the nearest whole number, the drip rate is approximately 19 gtt/min. Therefore, the nurse should set the manual IV infusion to deliver 19 gtt/min.

A. Have another nurse verify the medication for the secondary infusion. B. Flush the IV site with sterile water prior to connecting the secondary infusion. C. Hang the secondary infusion higher than the primary IV infusion. D. Disconnect the primary IV infusion to connect the secondary infusion. E. None F. None

Correct Answer is C

Explanation

A.While medication verification is important, this is not specific to administering an intermittent IV bolus. It is standard practice for high-alert medications, not routine antibiotics.

B. Flushing the IV site with sterile water prior to connecting the secondary infusion is not standard practice. Normal saline is typically used to maintain patency, but it is not necessary before connecting the secondary infusion.
C.To administer a secondary infusion (e.g., antibiotic), the secondary bag must be hung higher than the primary infusion. This allows gravity to prioritize the secondary infusion through the Y-site.

D. Disconnecting the primary IV infusion to connect the secondary infusion is not correct. The secondary infusion should connect to the primary line without disrupting the ongoing infusion unless otherwise indicated.
