The nurse is preparing a dose of ketorolac 12 mg IV using a 1 mL vial containing 30 mg/mL. How many mL should the nurse administer? (Enter numerical value only.)

here's how to calculate the volume (mL) of ketorolac the nurse should administer: 1. Dose of ketorolac to administer: Dose = 12 mg (given) 2. Concentration of ketorolac in the vial: Concentration = 30 mg/mL (given) 3. We need to find the volume (mL) containing the prescribed dose (12 mg) considering the concentration (30 mg/mL) in the vial. Volume to administer (mL): Dose (mg) / Concentration (mg/mL) Volume to administer (mL): 12 mg / 30 mg/mL Volume to administer (mL) = 0.4 mL (round to nearest tenth) Therefore, the nurse should administer approximately 0.4 mL of ketorolac intravenously.
