A nurse is preparing to administer methylprednisolone 10 mg IV bolus. The amount available from the pharmacy is 40 mg/mL. How many mL should the nurse administer? (Round to the nearest tenth.)

Step 1: Identify the required dose and concentration. Required dose = 10 mg Concentration = 40 mg/mL Result at step 1 = 10 mg ÷ 40 mg/mL Step 2: Calculate the volume in milliliters. 10 mg ÷ 40 mg/mL = 0.25 mL Result at step 2 = 0.25 mL Step 3: Round to the nearest tenth. 0.25 rounded to the nearest tenth = 0.3 mL Result at step 3 = 0.3 mL
