Question

14. A pediatric nurse practitioner orders Amoxil 60 mg po every 8 hours. The child weighs 12.5 pounds. The safe range is 20-40mg/kg/day in 3 equal doses. The available dose is 125mg/5mL. If safe, how many mLs will you give?

Answer 1

The safe range is 20-40 mg/ kg/day in 3 divided dose

The child weights abou 12.5 pounds

12.5 pounds =5.67 kilograms( divide mass by 2.205 )

So 20 mg / kg / day = 20×5.67 = 113.4 mg

So 40 mg / kg / day = 226.8 mg

So safe range is 113.4 - 226.8 mg

Ordered dose = 60 mg every 8 hourly - so in total 180 mg

So it is safe

Ml to be given

Ordered dose(D) = 60 mg

Dose in hand ( H) = 125 mg

Quantity it is in ( Q) = 5 ml

Amount to be administered (A) = ?

A= D×Q/ H

A= 60×5/125= 2.4 ml per time is to be given
