A child with pneumonia who weighs 20 lb
Question 1 of 5
Primary care provider orders cefazolin (Kefrol) 30 mg/kg in two divided doses per day for a child with pneumonia. Child weighs 20 lb. If the available oral suspension is 125 mg/5ml how many mls per dose should the child receive?
Correct Answer: A
Rationale:
To calculate the dose, we first convert the child's weight to kg: 20 lb / 2.2 = 9.09 kg. Next, we calculate the total daily dose: 30 mg/kg * 9.09 kg = 272.7 mg/day. Since the dose is divided into 2, each dose is 272.7 mg / 2 = 136.35 mg.
To find the volume needed, we divide the dose by the concentration of the suspension: 136.35 mg / 125 mg/5ml = 1.09 ml. However, the dose is divided into two, so each dose is 1.09 ml * 2 = 2.18 ml. Rounded to 1 decimal, the child should receive 2.2 ml per dose, closest to option A: 5.4 ml. Other choices are incorrect as they do not align with the calculated dose.
