Question

17. Your newborn client weighs 6 pound 4 ounces. You are ordered to give ampicillin 20 mg/kg/day IVP in divided dosed q. 12 hours. You are supplied with Ampicillin 5 mg in 1ml. The client will receive _________mL/dose (Round to second decimal place)

Answer 1

newborn weight = 6.4 lbs= 2.90= 3 kg ( 6.4 / 2.205)

ordered dose= 20mg/kg/day= 20 mg * 3 kg =60 mg per day ( twice daily)

so one dose = 30 mg

1 ml contains 5 mg

so , 30 mg in how many ml = 30/5=6 ml

so ,newborn receives 6 ml in each dose

or

weight = 2.90 kg

ordered dose= 2.90* 20 =58 mg per day , so one dose= 29 mg

1ml=5mg

therefore, how many ml for 29 mg = 29/5 = 5.8 ml
