    A nurse is preparing to administer amoxicillin 300 mg PO. The amount lable is amoxicillin oral solution 250 mg/5 mL. How many mL should the nurse administer? (Hound the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)

    Explanation & Rationale

    Given: Ordered dose of amoxicillin: 300 mg Concentration of amoxicillin oral solution: 250 mg/5 mL Step 1: Set up the proportion: Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL) Step 2: Substitute the values: 300 mg / Volume = 250 mg/5 mL Step 3: Solve for the unknown volume: Volume = 300 mg / (250 mg/5 mL) Volume = 300 mg x (5 mL / 250 mg) Volume = 6 mL
