Question

1. You are asked to draw out a pediatric dose of 0.8mg of a drug that comes as 2mg/ml. How many ml of this pediatric drug would you draw in a syringe?

A. 0.6 ml B. 1.6 ml C. 0.4 ml D. 1.2 ml

Answer 1

Ordered dose is 0.8 mg.

Drug available is 2mg per ml

As ordered dose only 0.8mg, so amount of drug to be administered in ml is calculated below.

1ml of vial contains 2 mg of the drug, dividing these values by 10 we get, 0.1 ml of vial contains 0.2 mg of the drug.

so, we can say that 0.5 ml of the vial contains 1mg of the drug.

And 0.4 ml contains 0.8 mg of the drug.

So, amount of drug to be administered is 0.4 ml.

Among the above option, C is correct.

I hope by the above information u got u r answer.
