A nurse is preparing to administer ketorolac 30 mg IM to a client who is postoperative. Available is ketorolac 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.)
Correct answer
A
Rationale
The correct answer is A: 2 mL. To calculate this, divide the total dose needed (30 mg) by the concentration of the medication (15 mg/mL). 30 mg / 15 mg/mL = 2 mL. Therefore, the nurse should administer 2 mL of ketorolac IM. Other choices are incorrect because they do not accurately calculate the required volume based on the given information. Choice B and beyond are empty because they are not relevant to the question.
