A nurse is preparing to administer ketorolac 30 mg IM for a loading dose. Available is ketorolac injection 15 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

To give a loading dose of ketorolac 30 mg IM, the nurse needs to calculate the volume of the injection solution. The solution has a concentration of 15 mg/mL, which means that every 1 mL contains 15 mg of ketorolac. To find the volume, the nurse can use the formula: volume = dose / concentration. Plugging in the values, we get: volume = 30 mg / 15 mg/mL = 2 mL. Therefore, the nurse should administer 2 mL of ketorolac injection for a loading dose.
