Question

1. A 1:10,000 epinephrine solution would contain how many milligrams of epinephrine QS AD 1 Liter of solution? A. 5000 mg B. 10,000 mg C. 100 mg D. 1000mg

Answer 1

Given, 1: 10000 epinephrine solution
1:10,000 epinephrine solution means 1 gram of epinephrine in 10,000 mL of solution
Now, 1 gram = 1000 mg
Hence, 1:10,000 epinephrine solution means 1000 mg(1 gram) of epinephrine in 10,000 mL of solution.

Now, 1 L = 1000 ml
Using unitary method:-
10000 ml of solution contain 1000 mg epinephrine
1 ml of solution contain=1000/10000 mg epinephrine
1000 ml of solution contain=(1000/10000)×1000 mg epinephrine
=100 mg epinephrine
Therefore, 100 mg epinephrine present in 1L(1000 ml) of solution.

Answer is option (C)100 mg
