Question

you receive an order for gentamicin, the order is for 5 mg/kg in two divided doses. the patient weighs 198 lbs. calculate how many mg the patient will receive in one dose? 990 mg 225 mg 450 mg

Explanation:

Step1: Convert pounds to kilograms

1 lb = 0.453592 kg, so 198 lbs = 198×0.453592 kg $\approx$ 90 kg

Step2: Calculate total daily dose

The dose is 5 mg/kg, so total daily dose = 5×90 mg = 450 mg

Step3: Calculate one - dose amount

The total daily dose is divided into two doses, so one - dose amount = $\frac{450}{2}$ mg = 225 mg

Answer:

225 mg
