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 ["17"]
Explanation
The correct answer is 17 mL/hour. To find the answer, we can use the following formula:
(mL/hour) = (units/hour) x (mL per unit)
Substituting the given values, we get:
(mL/hour) = (1,400) x (250 / 20,000)
Simplifying, we get:
(mL/hour) = (1,400) x (0.0125)
(mL/hour) = 17.5
(rounded mL/hour) = 17
Therefore, the nurse should program the infusion pump to deliver 17 mL/hour of heparin in dextrose 5% in water.
Correct Answer is ["1"]
Explanation
The correct answer is 1 mL. To find the answer, we can use the following steps:
- Convert the client's weight from pounds to kilograms by dividing by 2.2
- Multiply the weight in kilograms by the dosage in mg/kg
- Divide the dose in mg by the concentration in mg/mL
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (176) / (2.2) = 80 kg
- (dose in mg) = (0.05) x (80) = 4 mg
- (volume in mL) = (4) / (4) = 1 mL
- (rounded volume in mL) = 1 mL
Therefore, the nurse should administer 1 mL of lorazepam from the vial to the client.
