A nurse is preparing to administer ampicillin 150mg IM to an infant. Available is ampicillin injection 250mg/mL. How many mL should the nurse administer? Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.

Given: Prescribed dose: 150 mg of ampicillin Available concentration: 250 mg/mL Steps to solve: Determine the volume to be administered: Set up a proportion to solve for the unknown volume (X): 250 mg/mL = 150 mg/X mL Cross-multiplying gives us: 250 mg x X mL = 150 mg x 1 mL Simplifying: 250X = 150 Solving for X: X = 150 / 250 = 0.6 mL
