Practice Question
A nurse is preparing to administer cephalexin 50 mg/kg/day in divided doses every 8 hours to a child who weighs 33 lb. The amount available is cephalexin oral suspension 250 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) .
Answer Choices:
Correct Answer:
5
Rationale:
Step 1: Convert weight from pounds to kilograms
33lb÷2.2=15kg
Step 2: Calculate total daily dose
50mg/kg/day×15kg=750mg/day
Step 3: Divide the total daily dose into 3 doses (every 8 hours)
750mg/day÷3=250mg per dose
Step 4: Use available concentration to find mL per dose
250mg /5mL=50mg/mL
250mg per dose/50mg/mL=5mL
