A nurse is preparing to administer cefazolin 835 mg IM to an adolescent. The amount available is 330 mg/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.)

Identify the given information: Dose of cefazolin: 835 mg Concentration of cefazolin: 330 mg/mL Calculate the volume of cefazolin to be administered: Volume = Dose (mg) / Concentration (mg/mL) Substitute the values: Volume = 835 mg / 330 mg/mL Calculate the result: Volume ≈ 2.53 mL Round the answer to the nearest tenth: Volume ≈ 2.5 mL
