A physician orders Toradol (ketorolac) 30 mg IV push every 6 hours x 4 doses. A nurse has Toradol available as a 30 mg/mL injection.
How many millilitres per dose should the nurse administer to the patient?
0.6 mL
0.4 mL
1 mL
3 mL
The Correct Answer is C
The nurse should administer 1 mL per dose to the patient.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
30 mg / 1 mL = 30 mg / x mL
Cross-multiplying and solving for x gives:
x = 1 mL
Therefore, the nurse should administer 1 mL of Toradol injection to deliver 30 mg of the medication to the patient.

Correct Answer is B
Explanation
To find the rate in mL/hr, you need to use the formula for infusion rate:
Infusion rate (mL/h) = Total volume (mL) / Time (h)
Since the total volume is 500 mL and the time is 2 hours, plug in these values into the formula:
Infusion rate (mL/h) = 500 mL / 2 h
Simplify and solve for the infusion rate:
Infusion rate (mL/h) = 250 mL/h
Therefore, the nurse should set the IV pump to deliver **250 mL/h** to infuse LR 500 mL over 2 hours.
Correct Answer is D
Explanation
To answer this question, we need to calculate the infusion rate in mL per hour, then multiply it by the total time in hours, and finally divide it by 1000 to get the volume in litres.
The infusion rate in mL per hour is the amount of fluid that is given to a patient over a period of time. It can be calculated by dividing the total volume of fluid in mL by the total time in hours². In this case, the infusion rate is:
2.75 mL/min × 60 min/h = 165 mL/h
The total volume of fluid in mL is the infusion rate multiplied by the total time in hours. In this case, the total volume is:
165 mL/h × 7 h = 1155 mL
The volume in litres is the volume in mL divided by 1000. In this case, the volume in litres is:
1155 mL / 1000 = 1.16 L
Therefore, the correct answer is d. 1.16 L.
