Question

mary has an h - pylori infection. the provider has ordered a 1 gram of amoxicillin every 8 hours for 14 days. you have 250 mg tablets of amoxicillin in the medication room. how many tablets do you give the patient every 8 hours? how many tablets will the patient receive in a day?

Explanation:

Step1: Convert grams to milligrams

Since 1 gram = 1000 mg, and the ordered dose is 1 gram every 8 - hours.

Step2: Calculate the number of tablets every 8 - hours

The strength of each tablet is 250 mg. Let $n$ be the number of tablets. We use the formula $n=\frac{\text{Dose in mg}}{\text{Tablet strength in mg}}$. So $n = \frac{1000}{250}=4$ tablets every 8 hours.

Step3: Calculate the number of 8 - hour intervals in a day

There are 24 hours in a day. The number of 8 - hour intervals in a day is $\frac{24}{8}=3$.

Step4: Calculate the number of tablets in a day

Since 4 tablets are given every 8 hours and there are 3 eight - hour intervals in a day, the number of tablets in a day is $4\times3 = 12$ tablets.

Answer:

Every 8 hours: 4 tablets
In a day: 12 tablets
