A pediatric client with cerebral palsy receives a prescription for a 75% enteral nutrition formula of 320 mL to infuse at 80 mL/hour via an enteral feeding pump. The formula is available full strength in a 240 mL can. To prepare the solution, the nurse should use how many mL of the enteral nutrition formula? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["240 mL"]
To find the answer, we can use the following steps:
- Calculate the amount of water needed to dilute the formula to 75% by subtracting the volume of the prescribed solution from the volume of the full strength formula
- Subtract the amount of water from the volume of the can to get the amount of enteral nutrition formula
- Round the result to the nearest whole number
Using these steps, we get:
- (water in mL) = (320) - (240) = 80 mL
- (enteral nutrition formula in mL) = (240) - (80) = 160 mL
- (rounded enteral nutrition formula in mL) = 160 mL
Therefore, the nurse should use 160 mL of enteral nutrition formula from the can to prepare the solution.

Correct Answer is ["6 mL\/hour"]
Explanation
To find the answer, we can use the following steps:
- Convert the dosage of oxytocin from milliunits/min to units/hour by multiplying by 60
- Calculate the concentration of oxytocin in the IV bag by dividing the amount of oxytocin by the volume of solution
- Divide the dosage of oxytocin by the concentration of oxytocin in the IV bag to get the volume to be delivered
Using these steps, we get:
- (dosage of oxytocin in units/hour) = (2) x (60) = 120 milliunits/hour
- (concentration of oxytocin in IV bag) = (20) / (1000) = 0.02 units/mL
- (volume to be delivered in mL/hour) = (120 x 10^-3) / (0.02) = 6 mL/hour
Therefore, the nurse should program the infusion pump to deliver 6 mL/hour of oxytocin in lactated Ringer's to the patient.
Correct Answer is ["75"]
Explanation
To find the answer, we can use the following steps:
- Calculate the dose of diphenhydramine in mg per administration by multiplying the volume in mL by the concentration in mg/mL
- Multiply the dose in mg per administration by the number of administrations per day
- Round the result to the nearest whole number
Using these steps, we get:
- (dose in mg per administration) = (15) x (12.5 / 5) = 37.5 mg
- (total daily dose in mg) = (37.5) x (2) = 75 mg
- (rounded total daily dose in mg) = 75 mg
Therefore, the client receives 75 mg of diphenhydramine per day.
