mL
Explanation & Rationale
· Convert pounds to kilograms: 88 lb * (1 kg / 2.2 lb) = 40 kg · Calculate the maximum daily dose: 50 mg/kg/day * 40 kg = 2000 mg/day Prescribed dose: 500mg every 8 hours 24hrs/8= 3 doses Each dose= 500mg Daily dose =500mg X 3= 1500mg Available formulation= 250mg/5ml Ml to administer per day = 1500 X 5/250= 30ml Each dose= 30ml/3= 10ml
