You are preparing to give an intravenous dose of 400,000 units of penicillin G benzathine (Bicillin). The 10 mL ampule label reads penicillin G benzathine 300,000 units per mL. You prepare to administer how much of the medication?
  1. 1.3 mL
  2. 1.5 mL
  3. 10 mL
  4. 13 mL
Explanation
Answer: A - The nurse would administer 1.3 mL of penicillin G benzathine.
Desired dose: 400,000 units

Available concentration: 300,000 units (Units) per 1 mL (Volume)

(Desired dose ÷ Available concentration (units)) × Available dose concentration (volume) = Milliliters per desired dose

(400,000 units ÷ 300,000 units) × 1 mL = 1.3 × 1 mL = 1.3 mL
