Physician's Order The doctor orders Zithromax 500 mg orally, daily for a child who weighs 82 pounds. The safe dose range for this medication is 10-12 mg/kg/day. Zithromax is available in 250mg/tablets. Is the order safe?

Convert weight to kilograms: 82 lb ÷ 2.2 = 37.27 kg Calculate safe dose range: Minimum dose: 10 mg × 37.27 kg = 372.7 mg/day Maximum dose: 12 mg × 37.27 kg = 447.24 mg/day Compare with ordered dose: Ordered dose = 500 mg/day Safe range = 372.7 mg to 447.24 mg/day → 500 mg exceeds the maximum safe dose (447.24 mg) Final Answer: No, the order is not safe.
