The patient is a 3-year-old child who weighs 26 lb and has a severe infection. Ordered: Amoxicillin 120 mg po q8h On hand: See label. The package insert says the dosing regimen for children is 20 to 40 mg/kg/day q8h. Determine if the order is safe. If it is, calculate the amount to administer: ________. If the dose is not safe, write: not safe.
Fill in the blank(s) with the appropriate word(s).
0.48 mL
Convert weight to kg:
26 lb ×
= 11.818 kg, rounded to 11.8 kg
Calculate the maximum safe dose:
D = 40 mg/kg × 11.8 kg
D = 472 mg/day
Ordered dose = 120 mg × 3 daily = 360 mg. This is lower than the maximum safe dose, so it is safe to administer.
Calculate the amount to administer: H = 250 mg; Q = 5 mL; D = 120 mg
A = 0.48 mL
