How many milligrams of epinephrine are in 5cc of a 1:10,000 solution?
  1. 5
  2. 50
  3. 500
  4. 0.5
Explanation
Answer: D - 0.5 mg of epinephrine is in 5cc of a 1:10,000 solution. First, you must convert the concentration (1:10,000) to mg / cc. The conversion ratio is 1:10,000 = 1000mg/10,000cc = 0.1mg/cc. Next divide the dosage given (5cc) by the mL available (1 mL).Then multiply it by the mg /cc (0.1) for a total of 0.5 mg.
