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 ["2"]
Explanation
The correct answer is 2 ounces. To find the answer, we can use the following steps:
- Calculate the volume of magnesium hydroxide in mL by dividing the dose in mg by the concentration in mg/mL
- Convert the volume in mL to ounces by multiplying by 0.0338
- Round the result to the nearest whole number
Using these steps, we get:
- (volume in mL) = (4800) / (400) = 12 mL
- (volume in ounces) = (12) x (0.0338) = 0.4056 ounces
- (rounded volume in ounces) = 2 ounces
Therefore, the nurse should instruct the client to take 2 ounces of magnesium hydroxide Saline Laxative, USP with each dose.
Correct Answer is ["105"]
Explanation
To find the answer, we can use the following steps:
- Convert the infant's weight from grams to kilograms by dividing by 1000
- Multiply the weight in kilograms by the dosage in mg/kg/day
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (3,500) / (1000) = 3.5 kg
- (dose in mg/day) = (30) x (3.5) = 105 mg/day
- (rounded dose in mg/day) = 105 mg
Therefore, the nurse should administer 105 mg of ceftazidime daily to this infant.
