The nurse is initiating a prescription for Dextrose 2.5% in 0.45% Sodium Chloride (D2.5W, 0.45% NS) at 45 mL/hour for a child with dehydration. The nurse attaches a volume-control administration set with a microdrip chamber to the bag of solution. How many microdrops/minute should the nurse regulate the infusion? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["45"]
To find the answer, we can use the following formula:
(microdrops/minute) = (mL/hour) x (microdrops/mL) / 60
Substituting the given values, we get:
(microdrops/minute) = (45) x (60) / 60
Simplifying, we get:
(microdrops/minute) = 45
Therefore, the nurse should regulate the infusion to deliver 45 microdrops/minute of Dextrose 2.5% in 0.45% Sodium Chloride.

Correct Answer is ["600"]
Explanation
The correct answer is 600 mL/hour. To find the answer, we can use the following formula:
(mL/hour) = (mL/minute) x 60
Substituting the given values, we get:
(mL/hour) = (200 / 20) x 60
Simplifying, we get:
(mL/hour) = 10 x 60
(mL/hour) = 600
Therefore, the nurse should set the infusion pump to deliver 600 mL/hour of 0.9% NS to the patient.
Correct Answer is ["10.2"]
Explanation
To determine the infusion rate in mL/hour for the dopamine solution:
-
Calculate the total dose per minute:
3 mcg/kg/min×91 kg=273 mcg/min3mcg/kg/min×91kg=273mcg/min. -
Convert mcg/min to mcg/hour:
273 mcg/min×60 min/hour=16,380 mcg/hour273mcg/min×60min/hour=16,380mcg/hour. -
Convert mcg to mg:
16,380 mcg÷1,000=16.38 mg/hour16,380mcg÷1,000=16.38mg/hour. -
Determine the concentration of the solution:
400 mg÷250 mL=1.6 mg/mL400mg÷250mL=1.6mg/mL. -
Calculate the mL/hour required:
16.38 mg/hour÷1.6 mg/mL=10.2375 mL/hour16.38mg/hour÷1.6mg/mL=10.2375mL/hour.
Rounded to the nearest tenth:
10.2 mL/hour.
