This problem is from a New York Times article. Researchers tested a group of 28 doctors. The doctors were told that a 5-year-old child suffering a potentially fatal allergic reaction to peanuts needed an emergency injection of 0.12 mg of epinephrine. The bottle of epinephrine is labeled 1 mg in 1 mL of solution. What volume of this solution would you inject if you were the doctor

0.12 mL of the epinephrine solution.

Explanation:

We have:

A bottle of epinephrine labeled 1 mg in 1 mL of solution,

We need to prepare:

An injection of 0.12 mg of epinephrine

Hence:

Therefore, to prepare an injection of 0.12 mg of epinephrine labeled 1 mg in 1 mL we need to inject 0.12 mL of the epinephrine solution.          

I hope it helps you!

the correct answer would be d. hope this !
