Question

A patient is to be given 35 milligrams of Demerol every 4 hours. You have Demerol 50 milligrams/milliliter in stock. How many milliliters should be given per dose?

Answer 1

0.7 milliliter

Explanation:

We know that 35 milligrams of Demerol is to be given to a patient every 4 hours and we have Demerol 50 milligrams/milliliter in stock.

To find out the number of milliliters that should be given per dose, we use the simple ratio method.

`(1 milliliter)/(x) = \frac{50 milligrams} {35 milligrams}`

`x=(35)/(50)`

`x=0.7`

Therefore, 0.7 milliliter of Demerol should be given per dose.

Answer 2

0.7 milliliters should be given per dose.

Explanation:

50 milligrams = 1 milliliter

Per dose, you need to give 35 milligrams. So, to know the amount of milliliters, we need to figure out what fraction is 35 out of 50?

35 divided by 50 is
`(35)/(50)=0.7`

Hence, 0.7 milliliters should be given per dose.
