Order Entry & ProcessingQuestion 85 of 100
A 22 kg child is ordered cefdinir 10 mg/kg per dose every 8 hours. The suspension supplied is 100 mg/5 mL. What volume should be given per dose?
a.11 mL
b.2.2 mL
c.22 mL
d.33 mL
Explanation
The dose is 22 kg x 10 mg/kg = 220 mg. At 100 mg/5 mL the concentration is 20 mg/mL, so 220 mg / 20 mg/mL = 11 mL per dose. Answering 2.2 mL comes from dividing 220 mg by 100 mg and forgetting that each 100 mg occupies 5 mL.
