9. A nurse is preparing to administer penicillin G benzathine 1.2 million units IM now. The amount available is penicillin G benzathine 600,000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
To administer the correct dose of penicillin G benzathine, which is 1.2 million units, and given that the available concentration is 600,000 units per mL, the nurse should calculate the volume to administer based on these values. By dividing the prescribed dose by the concentration available, the nurse can determine the volume needed for injection. In this case, 1.2 million units divided by 600,000 units per mL results in 2 mL.
