Ontario Registered Pharmacy Technician (RphT) Practice Exam

Question: 1 / 400

The standard pediatric dose for cefazolin is 20mg/kg/day. The order is written for 150mg tid. The infant weighs 8lbs. The dose is:

Too high

It is important to calculate the dose of a medication based on the patient's weight because infants and children require different dosing compared to adults. In this case, the standard pediatric dose for cefazolin is 20mg/kg/day, which means the correct dose for this infant would be 72mg per day (20mg/kg x 3.6kg). However, the order is written for 150mg tid, which equates to 450mg per day. This is significantly higher than the recommended dose and could lead to potential toxicity in the infant. Therefore, the correct answer is A Too high. Option B is incorrect because the dose is actually higher than what is recommended, not too low. Option C may seem like a possible correct answer, but it is important to always double check dose calculations in order to ensure patient safety.
