The recommended dose of cefuroxime sodium for children older than 1 month is 50-133 mg/kg every 24 hours. Is the ordered dose within the recommended limits? (YES or NO) __________ YES WNL 55 lb = 25 kg Recommended 24-hour dose range =[(lower dose range) 50 × 25] to [(higher dose) 133 × 25]= 1,250 mg to 3,325 mg Medication order: 750 mg × 4 times a day = 3,000 mg/day Yes, dose is within acceptable limits. The nurse works in a NICU (neonatal intensive care unit). The doctor orders Digoxin 6 mcg/kg/day IV in two divided doses to be given to one of the nurse’s patients. The patient weighs 7 pounds. Calculate the amount, in mcg, the nurse will give per dose.

9.5mcg First, convert the infant's weight into kilograms from pounds. There are a couple of formulas to do this. You can divide the number of pounds by 2.2 or multiply the number of pounds by 0.454. 7 lbs divided by 2.2 = 3.18 kg Now calculate the medication to be given to the patient per day. 6 mcg × 3.18 kg = 19.08 mcg/day Divide in 2 to get the per-dose amount: 19.08 ÷ 2 = 9.54 mcg per dose. Round to the nearest 10th place = 9.5mcg/per dose Hide definitions
