Question

A patient is prescribed Keflex 0.5 g by mouth twice a day for 7 days. How many capsules should be

provided for the entire week if each table contains 500 mg/capsule?

Answer 1

To determine the number of capsules needed for the entire week, we need to calculate the total dosage required and divide it by the dosage strength per capsule.

The patient is prescribed Keflex 0.5 g (or 500 mg) by mouth twice a day for 7 days. Therefore, the total dosage required for the week is:

Total dosage = Dosage per dose × Number of doses per day × Number of days

Total dosage = 0.5 g × 2 × 7 = 7 g

Since each capsule contains 500 mg (0.5 g), we can calculate the number of capsules needed by dividing the total dosage by the dosage strength per capsule:

Number of capsules = Total dosage / Dosage per capsule

Number of capsules = 7 g / 0.5 g = 14 capsules

Therefore, for the entire week, 14 capsules should be provided.

Answer 2

Keflex 0.5 g is equivalent to 500 mg. The patient is prescribed 500 mg twice a day for 7 days, which is a total of 14 doses. Since each capsule contains 500 mg, the patient will need 14 capsules for the entire week.
