Question

You are a pharmacy technician. You need to prepare a 0.85-gram dose of a liquid antibiotic. The medicine is concentrated at 250 milligrams of antibiotic per 5 milliliters of liquid. How many milliliters should you pour into a prescription bottle?

Answer 1

17 milliliters of dose should be poured into a prescription bottle.

Explanation:

Amount of dose in liquid antiboitic = 0.85 g = 850 mg

1 g = 1000 mg

Concentration of antibiotic = 250 mg/5 ml = 50 mg/mL

So, in 1 mL of liquid we have 50 mg of antibiotic.

Then in 0.85 mg of antibiotic will be:

`(1)/(50)* 850 mL=17 mL`

17 milliliters of dose should be poured into a prescription bottle.

Answer 2

17mL

Explanation:

Convert 0.85 gr to miligrams

If 100 mg is 1 gr. Then, 0.85 gr is 850 mg

So, 850 multiply for 5ml and divide for 250 ml

or
`850mg  (5ml)/(250mg)`

So all mg is gone and the amount of mililiters is 17
