Question 1 of 5

The physician ordered cephalexin 4 mg/kg PO Q6 hours. The medication is available at 250 mg/5 mL. The client weighs 245 pounds. What is the correct dose to be administered every 6 hours? (Round the answer to the nearest whole number. Do not use a trailing zero.)

Correct Answer: 9

Rationale: Client weight: 245 lbs ÷ 2.2 = 111.36 kg. Dose: 4 mg/kg × 111.36 = 445.44 mg. Available: 250 mg/5 mL, so 445.44 ÷ (250/5) = 8.91 mL, rounded to 9 mL.
