Lee Wilkerson · Answer 1

A. Quantity of saline = 500mL

Rate of infusion = 80 mL / h

Infusion time = Quantity / Rate = 500 mL / (80 mL/hr) = 6.25 hr

b. Child weight = 72.6 lb = 32.93 kg

Medrol to be given = 1.5 mg per kg

Quantity of Medrol = 20 mg/mL

Dosage available = 20 mg/mL / 1.5 mg/kg = 13.33 kg/mL

Dosage according to body weight = 32.93 kg / 13.33 kg/mL = 2.47 mL
