The dose is safe Body Surface Area (BSA) in meters square method of calculations may be seen____________ - ANS- in NICU, ICU and high acuity areas such as oncology. calculate dose pepcid is provided as 10 mg/ml - ANS- 10 mg/1mL= 5 mg/ X mL 5/10x = 0.5 mL of Pepcid child: 5 years: weight 44 lbs order: famotidine (pepcid) 5 mg IV bid Drug guide: 0.25 mg/Kg q 12 hr IV up to 40mg/day. - ANS- Convert lb t kg: 44 kg= 20 kg Determine safe dose: 20 kg* 0.25 mg= 5 mg 5 mg is safe meets mg/kg rule and does not Exceed 40 mg/day 5 mg bid= total of 10 mg/day convert :20 pounds 5 ounces to kilogram - ANS- 1st: need to convert 5 ounces to a fraction of a pound 5 divided by 16=0.31 2nd: 20.31 pounds divided by 2.2=9.23 kg Note: medication would be calculated based on 9.23 kilograms DO NOT ROUND TO 9.2 Crucial in the pediatric population - ANS- Children can get into fluid overload very quickly with dire consequences Daily FluidNeeds - ANS- Fluid needs should be calculated on every patient to assure that the infant / child is receiving the correct amount of fluids. Standard formula for pediatrics needs to be memorized Fluid calculation can be rounded - ANS- You cannot administer a fraction of mL. In child 1 the calculated hourly rate of 29.7 would be rounded to 30 mL/hour. in child 2 the calculated hourly rate of 70.04 would be rounded to 70 mL / hour. fluid calculations:::::::::Jose weight 16lb - ANS- 1st: Convert to kg 16/2.2= 7.27 Kg 2nd: using IV fluid calculation 100 mL * 7.27 Kg= 727 mL (you only use the 100 mL because the weight is less than 10kg) As a result, 727 mL/24 hrs or 30 mL per hour.
