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"]
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 ["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.
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.
