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.)
The Correct Answer is ["2.5"]
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
