Question

Cephalexin is an antibiotic that frequently is prescribed in 500-mg tablets. A doctor prescribes 2 grams of cephalexin per day for a patient with a skin abscess. How many 500-mg tablets would have to be taken in order to achieve this daily dosage?

Answer 1

4 tablets per day

convert 500mg to 0.5g

Divide 2/0.5= 4

Answer 2

Answer: 4

Step-by-step explanation:

Cephalexin is an antibiotic that is prescribed in 500-mg tablets and a doctor prescribes 2 grams of cephalexin each day for a patient.

To get the number of 500-mg tablets that would have to be taken in order to achieve the daily dosage goes this:

1000 milligrams= 1 gram

Therefore, 2 grams= 2 × 1000= 2000 milligrams.

Since the drugs are sold in 500mg and the patient is expected to take 2grams which is 2000mg. We divide: 2000 ÷ 500 = 4

The patient is expected to take 4 500-mg tablets to achieve this daily dosage.
