Question

A doctor orders 200 mg of Rocephin to be taken by a 15.4 lb infant every 8 hours. The medication label shows that 75-150 mg/kg per day is the appropriate dosage range. Is this doctor's order within the desired range? I5.4lb 22-7k7 4es

Answer 1

Yes, the doctor's order within the desired range

Explanation:

Given:

Dosage of Rocephin ordered = 200 mg

Mass of the infant = 15.4 lb

1 lb = 0.453592 kg

thus,

15.4 lb = 0.453 × 15.4 = 6.97 kg

Dosage is provided every 8 hours

thus,

Number of dosage per day =
`\frac{\textup{24 hours}}{\textup{8}}` = 3

Hence,

the total dosage ordered per day = 200 × 3 = 600 mg

Dosage ordered per kg of infant per day =
`\frac{\textup{600}}{\textup{6.97}}`

or

Dosage ordered per kg of infant per day = 86.083 mg/kg per day

Yes, the doctor's order within the desired range
