A nurse is preparing to administer ketorolac 45 mg IM to a client who reports severe pain. Available is ketorolac injection 30 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.5"]
Calculation:
Desired dose = 45 mg.
Available concentration = 30 mg/mL.
Calculate the volume to administer.
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 45 mg / 30 mg/mL
= 1.5 mL.
Rounded to the nearest tenth: 1.5.

Correct Answer is A
Explanation
A. mcg: This abbreviation stands for microgram, which is a metric unit of weight commonly used in medication dosing. It is part of the metric system, where 1,000 mcg = 1 mg (milligram).
B. mL: Milliliter is a metric unit of volume, not weight. It is used to measure liquid quantities, such as medication doses or fluid intake/output.
C. Ib: "Pound" (lb or Ib) is a non-metric (imperial) unit of weight. Although commonly used in the U.S., it is not part of the metric system.
D. oz: "Ounce" is also a non-metric unit of weight or volume, depending on context, used in the imperial system. It is not used in metric-based medication dosing.
