The nitroprusside concentration is 50 mg/250 mL of D5W. How many micrograms per kilograms per minute of nitroprusside are infusing? __ 50mg/ 250 ml = 50,000 mcg/ 250 ml 250 / 50 = 5 50,000 / 5 = 10,000 10,000 / 60 = 166.67 166.67 / 70 kg = 2.4 The recommended dosage of oxacillin for a child is 50 mg/kg/day in four equal doses. The child's weight is 66 lb. The medication is supplied in 250 mg/5 mL.

Calculate the rate in drops per minute for each dose of this IV medication. __ 44 lb/ 2.2 kg = 20 kg 20 kg x 6 mg = 120 mg /day = 60 mg/dose (100 x 60 ) / 90 = 66.666667 = 67 ASWER IN WHOLE NUMBERS Maintenance Rate Table Weight RangeRequired Daily Fluid 0–10 kg1 00 mL/kg >10–20 kg 1,000 mL + 50 mL/kg (for every kg > 10 kg) >20 kg 1,500 mL + 20 mL/kg (for every kg > 20 kg) A child is to receive IV fluids at maintenance rate. The child weighs 75 lb. Calculate the 24-hour fluid requirements for this patient. __` 75 lb/ 2.2 kg = 34.1 kf 1,500 + (14 x 20) + (.1 x 20 ) = 1,782 The physician orders cephalexin 250 mg oral every 6 hours for a child weighing 44 lb. The cephalexin is available in a 250 mg/5 mL concentration. How many milligrams per kilogram per 24 hours is the patient receiving? __` 44 lb/ 2.2 kg = 20 kg 24 hour / 6 = 4 times 250 x 4 = 1,000 mg/day 1000 / 20 = 50 The recommended safe dose of rifampin for a child is 5 mg/kg/dose. The child's weight is 11 lb. The medication is supplied in 10 mg/mL. How many milliliters will be administered for each dose? __ 11 lb/ 2.2 kg = 5 kg 5 kg x 5 mg = 25 mg/dose 25/ 10 mg = 2.5 The physician orders 60 mg of prednisone daily to be divided in three equal doses.
