A five-year-old child suffering a potentially fatal allergic reaction to peanuts needs an emergency injection of 0.12 mg of epinephrine from a bottle labeled 100 $\mu$g epinephrine per mL of solution.What volume of this solution should the child receive?

Question

Quizplus · Accepted Answer

To calculate the volume of solution needed, we can use the following formula:

(volume of solution needed) = (amount of medication needed) / (concentration of medication in solution)

Substituting the given values, we get:

(volume of solution needed) = 0.12 mg / 100 μg/mL

Converting mg to μg by multiplying by 1000, we get:

(volume of solution needed) = 120 μg / 100 μg/mL

Simplifying, we get:

(volume of solution needed) = 1.2 mL

Therefore, the best choice is E: 1.2 mL.
