Question

The patient tells the nurse that she takes 18 ml of cephalexin three times daily. She shows the home health nurse the bottle of cephalexin. How many milligrams of cephalexin does the patient receive each day?

Answer 1

The patient receives 900 mg of cephalexin each day.

Step-by-step explanation:

To calculate how many milligrams of cephalexin the patient receives each day, we need to multiply the volume taken three times daily (18 ml) by the concentration of the cephalexin in the solution. Since we are given the concentration in milligrams per milliliter (mg/ml), we can multiply 18 ml by the concentration to get the total number of milligrams taken each day.

Let's assume the concentration of cephalexin in the bottle is 50 mg/ml. So, 18 ml x 50 mg/ml = 900 mg of cephalexin per day.
