ATI LPN Dosage Calculation PN Nursing Care of Children Proctored Assessment 3.1
Calculation
A nurse is preparing to administer penicillin G benzathine 1,200,000 units IM to a school-age child. Available is penicillin G benzathine injection 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.)
mL
Explanation & Rationale
To calculate the volume of penicillin G benzathine injection required, divide the prescribed dose by the concentration available. In this case, 1,200,000 units prescribed divided by 600,000 units per mL results in 2 mL.
