Question

1. (2 points) a doctor administers penicillin v to a 120-kg patient, using a dosage formula of 50 mg per kg per day. assume that penicillin v is available in 500-mg tablets. how many tablets should a 120-kg person take every 6 hours?

Explanation:

Step1: Calculate daily total dose

Daily dose = $50\ \text{mg/kg} \times 120\ \text{kg} = 6000\ \text{mg}$

Step2: Calculate dose per 6-hour interval

Number of 6-hour periods in a day = $\frac{24}{6} = 4$
Dose per interval = $\frac{6000\ \text{mg}}{4} = 1500\ \text{mg}$

Step3: Calculate number of tablets per interval

Tablets per interval = $\frac{1500\ \text{mg}}{500\ \text{mg/tablet}} = 3$

Answer:

3 tablets
