Administer 0.3 mL of 1:1000 solution of epinephrine S.Q.. How much drug is being injected? show your work?

Question

This question was one of our practice problems and I can't figure out how to work it out and we have to show our work so we can go on to the actual lesson. PLEASE HELP!

Answer 1

A 1:1000 solution has 1 mL active ingredient per 1000 mL solution.

(0.3 ml sol.)(1 ml act./1,000 ml sol.) =

0.0003 ml epinephrine = 0.3 μl epinephrine

Answer 2

A 1:1000 solution has 1 gram active ingredient per 1000 mL solution.

So we convert the gram to mg

1:1000 solution adrenaline

= 1g adrenaline in 1000ml solution

= 1000mg adrenaline per 1000ml solution

= 1mg per ml

(0.3 mL dose)(1 mg) =

= 0.3mg epinephrine

or

(0.3mL)(1g/1000ml)

=0.0003 gram

convert that to mg by multiplying by 1000 (1 g = 1000mg)

=0.3mg epi
