Question

an antibiotic is available in a solution with a concentration of 75 mg per 5 ml of solution or in 75 - mg capsules. the recommended dosage of the antibiotic is 15 mg/kg per day. complete parts (a) and (b). a. how many capsules should a 80 - kg person take every 3 hours? a 80 - kg person should take capsule(s) every 3 hours. (round to the nearest integer as needed.)

Explanation:

Step1: Calculate daily dosage

The recommended dosage is 15 mg/kg per day. For an 80 - kg person, the daily dosage is $15\times80 = 1200$ mg.

Step2: Calculate dosage per 3 - hour interval

There are $24\div3 = 8$ intervals of 3 hours in a day. So the dosage per 3 - hour interval is $\frac{1200}{8}=150$ mg.

Step3: Determine number of capsules

Each capsule has 75 mg of the antibiotic. So the number of capsules per 3 - hour interval is $\frac{150}{75}=2$.
