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
shusha [124]

Answer:

We inject 60.9628 milliliters of dosage.

Step-by-step 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\times 0.453592=76.203456  kg

The dosage is 0.4 mg per kilogram of bod.

So, dosage of patient weight = 0.4 \times 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\times 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= \frac{30.4814}{0.5} = 60.9628

Therefore, We inject 60.9628 milliliters of dosage.
