Practice Question

A nurse is preparing to administer 2.4 million units of penicillin G intramuscularly for a client who is both positive for HIV and syphilis. The prescriber ordered 2.4 million units 1M every week for three consecutive weeks. The available dose comes in a 600,000/mL vial. How many mL of medications would the client receive per dose?

Answer Choices:

Correct Answer:

4

Rationale:

✔ Step 1: Identify the prescribed dose and available concentration

Prescribed dose = 2,400,000 units

Available = 600,000 units/mL

✔ Step 2: Use the formula to calculate mL

mL = Dose ÷ Concentration

mL = 2,400,000 ÷ 600,000 = 4

✔ Step 3: Rounding

Already a whole number = 4 mL
