Question

You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed as 500 ug/ml. The patient's chart Hists weight as 168 pounds. How many milliliters (= cc) are you to inject? Patient's weight Concentration of drug Show calculations: mg/ml

Answer 1

We inject 60.9628 milliliters of dosage.

Explanation:

Given : You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed as 500 ug/ml. The patient's chart Hosts weight as 168 pounds.

To find : How many milliliters (= cc) are you to inject?

Solution :

We know that,

1 pound = 0.453592 kg,

Patient's weight = 168 pounds

Patient's weight in kg =
`168* 0.453592=76.203456` kg

The dosage is 0.4 mg per kilogram of bod.

So, dosage of patient weight =
`0.4 * 76.2035\ mg = 30.4814\ mg`

We know, 1 micro gram = 0.001 mg

Concentration of drug is given by,

`500\ \text{micro grams/ml}= 500* 0.001\ \text{mg/ml} = 0.5\ \text{mg/ml}`

Now we are supposed to find milliliters inject,

So, milliliters of dosage required to inject is

`d= (30.4814)/(0.5) = 60.9628`

Therefore, We inject 60.9628 milliliters of dosage.
