Question

a nurse is preparing to administer amoxicillin 30 mg/kg/day po divided in equal doses every 12 hr to an infant who weighs 5.5 kg. available is amoxicillin suspension 125 mg/5 ml. how many ml should the nurse administer per dose? (round the answer to the nearest tenth. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Calculate daily dose

Daily dose = 30 mg/kg/day × 5.5 kg = 165 mg/day

Step2: Calculate per dose amount

Per dose = $\frac{165\ \text{mg/day}}{2\ \text{doses/day}}$ = 82.5 mg/dose

Step3: Calculate mL per dose

mL per dose = $82.5\ \text{mg} × \frac{5\ \text{mL}}{125\ \text{mg}}$ = 3.3 mL

Answer:

3.3
