A child must take 10 mL of cephalexin, an antibiotic, by mouth 2 times a day for 10 days. The solution is provided as a 50 mg/mL suspension. How many milligrams will the child have taken when the course of medication is over?
10 days * 2doses/day * 10mL/dose * 50mg/mL = 10*10*2*50 mg
To calculate the total amount of milligrams the child will have taken, we need to multiply the volume (in milliliters) by the concentration (in milligrams per milliliter), and then multiply by the number of doses.
Given:
- Volume of solution per dose: 10 mL
- Concentration of the suspension: 50 mg/mL
- Number of doses per day: 2
- Number of days: 10
First, let's find the amount of milligrams per dose:
10 mL (volume per dose) × 50 mg/mL (concentration) = 500 mg (milligrams per dose)
Next, let's find the total amount of milligrams per day:
500 mg (milligrams per dose) × 2 doses (per day) = 1000 mg (milligrams per day)
Finally, let's find the total amount of milligrams over the entire course of medication:
1000 mg (milligrams per day) × 10 days = 10,000 mg (total milligrams over 10 days)
Therefore, the child will have taken 10,000 milligrams of cephalexin when the course of medication is over.
