Clinical Medical Assistant Exam Practice Question
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?
Correct Answer: B
Rationale: To determine the dosage of amoxicillin, consider the concentration provided: 400 mg per 10 mL. Since the prescription instructs the child to take 10 mL of the medication, the calculation is straightforward. Each 10 mL dose contains 400 mg of amoxicillin, making option B the correct choice.
Option A (800 mg) incorrectly assumes that two doses are being taken at once, which is not the case. Option C (200 mg) miscalculates the dosage by halving the correct amount. Option D (100 mg) significantly underestimates the dosage, failing to account for the full 10 mL. Hence, 400 mg is the accurate dosage per administration.
