The healthcare provider prescribes amoxicillin 500 mg every 8 hours for a child who weighs 88 pounds. The recommended maximum safe dose is 50 mg/kg/24 hour. The available suspension is labeled, "Amoxicillin Suspension 250 mg/5 mL." Based on this child's weight, how many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the whole number.)
The Correct Answer is ["10 mL"]
To find the answer, we can use the following steps:
- Convert the child's weight from pounds to kilograms by dividing by 2.2
- Calculate the volume of amoxicillin suspension in mL by dividing 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) = (88) / (2.2) = 40 kg
- (volume in mL) = (500) / (250 / 5) = 10 mL
- (rounded volume in mL) = 10 mL
Therefore, the nurse should administer 10 mL of amoxicillin suspension to the child.

Correct Answer is ["240 mL"]
Explanation
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 ["42"]
Explanation
To find the answer, we can use the following formula:
(gtt/min) = (mL/hour) x (gtt/mL) / 60
Substituting the given values, we get:
(gtt/min) = (1000 / 8) x (20) / 60
Simplifying, we get:
(gtt/min) = 125 x 20 / 60
(gtt/min) = 41.667
(rounded gtt/min) = 42
Therefore, the nurse should regulate the infusion to deliver 42 gtt/minute of lactated Ringer's.
