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

Answer:

It should be given 0.7 milliliters of Demerol (50 milligrams/millilitre) per dose.

Step-by-step explanation:

You have Demerol 50 milligrams/milliliter in stock, and the patient is to be given 35 milligrams of Demerol every 4 hours (per dose), then we can use a rule of three:

Milliliter     Milligrams

    1        →        50

    x       →         35

$x=\frac{(35 mg)(1 ml)}{50 mg}\\ x=\frac{35}{50}ml\\ x=0.7 ml$

Answer 2

Answer:

0.7 milliliter

Step-by-step explanation:

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

So we can use the simple ratio method to find the number of milliliters that should be given per dose.

$\frac{1 milliliter}{x} = \frac{50 milligrams} {35 milligrams}$

$x=\frac{35}{50}$

$x=0.7$

Therefore, every dose of Demerol of 0.7 milliliter should be given to the patient.
