Ordered 15 g of Amoxicillin. Amoxicillin is available as 10 g per 20 mL. How much will the MA draw up?

Answer 1

This is simply a ratio problem. You start with 15 g of amoxicillin (the amount needed). For every 10 g of amoxicillin you will need 20 ml. So the ratio is 20 ml / 10 g amoxicillin.

15 g amoxicillin ( 20 ml ⁄ 10 g amoxicillin) = 30 ml

Answer 2

Formula: Dose order/dose on hand X total available quantity

Therefore: 15g/10gX20mL

=1.5X20mL

=30mL

Answer 3

If there are 10 g in 20 ml, and you need 15 g, then you obviously need more than 20 ml, right? How much more? Well, another 10 ml. Here's how to do it using dimensional analysis (unit factor method)...

15 g amoxicillin x 20 ml/10 g amoxicillin = 30 mls needed

15 g x 20 ml = 30 mls

10 g
