Arizona Certified Caregiver Practice Exam

The Physician orders 500mg of amoxicillin to be given in an oral suspension. The unit dose is 250mg per 5 ml. What should you administer?

1. 3 ml

2. 5 ml

3. 10 ml

4. 15 ml

The correct answer is: 10 ml

To calculate the correct administration for 500mg of amoxicillin, you need to divide the total dose (500mg) by the unit dose (250mg per 5ml). This will give you the number of unit doses needed (2). In order to reach this amount, you will need to administer a total of 10 ml (5ml x 2) of the oral suspension. The other options are incorrect because they do not provide the correct amount of medication needed for the prescribed dose. Option A would provide 250mg, Option B would provide 5 ml, and Option D would provide 750mg, which is much more than the prescribed 500mg.
