The child weighs 32 lb. The physician orders ampicillin 100 mg/kg/24 hours. How many mg do you give in one day (24 hours)?

________ mg/24 hr.

(Remember to round the weight to the nearest tenth.)

Answer :

The dosage of ampicillin in 24 hours by multiplying the weight of child with the dose of ampicillin per kg per day and rounding off the value to the nearest 10th.

Given:

Weight of child=32 lb

Ampicillin dose=100 mg/kg/24hours

We have to calculate the dosage of ampicillin in 24 hours.

So first we will convert the weight of child in kg:

32 lb × (1 kg / 2.20462 lb) = 14.515 kg

Now we will multiply weight of child with the ampicillin dose:

14.515 kg × 100 mg/kg/24 hours = 1451.5 mg/24hours

Rounding off the value of dosage to the nearest 10th = 1450 mg/24hours

Therefore, the dosage of ampicillin in 24 hours is 1450 mg/24hours.

Explanation: To solve this question, first we have converted the weight of child in kg. Then we have multiplied it with the dose of ampicillin per kg per day to calculate the dose of ampicillin in 24 hours. And then we have rounded off the value of dosage to the nearest 10th. And we got the dosage of ampicillin in 24 hours as 1450 mg/24hours.

The conclusion is that we can calculate the dosage of ampicillin in 24 hours by multiplying the weight of child with the dose of ampicillin per kg per day and rounding off the value to the nearest 10th.
