A child is prescribed liquid amoxicillin, and the instructions indicate that the child should take 10 mL of the medication every 12 hours for 7 days. The liquid amoxicillin has a concentration of 400mg/10mL. What is the correct dosage of amoxicillin in milligrams for each dose?

Rationale

The correct dosage of amoxicillin for each dose is 400 mg.

The concentration of the liquid amoxicillin is 400 mg per 10 mL. Therefore, when the child is instructed to take 10 mL, they will be receiving exactly 400 mg of amoxicillin with each dose.

A (800 mg) YOUR ANSWER

This choice represents double the actual dosage. The prescribed amount of 10 mL corresponds to 400 mg, not 800 mg, as that would require 20 mL of the solution, which is not indicated in the instructions.

B (400 mg) CORRECT

This is the correct calculation based on the provided concentration of the amoxicillin solution. Since the concentration is 400 mg per 10 mL, administering 10 mL results in a dosage of 400 mg.

C (200 mg) YOUR ANSWER

This choice suggests half of the actual dosage. Administering 10 mL of the amoxicillin would yield 400 mg, not 200 mg, which could occur if only 5 mL were prescribed.

D (100 mg) YOUR ANSWER

This choice is significantly lower than the correct dosage. A dosage of 100 mg would require only 2.5 mL of the liquid amoxicillin, which is not the amount specified in the prescription.

Conclusion

The proper dosage of liquid amoxicillin for the child, based on the concentration of 400 mg per 10 mL and the prescribed amount of 10 mL every 12 hours, is 400 mg. Understanding the correct dosage is vital for effective treatment, ensuring that the child receives the appropriate amount of medication as instructed.
