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.

Explanation
The correct technique for preparing this insulin order is to follow these steps¹²:
- Perform hand hygiene and put on gloves.
- Mix NPH (cloudy) insulin by gently rotating the vial between the palms of your hands. Do not shake the vial.
- Clean the tops of both vials with alcohol swabs and let them dry.
- Draw up the amount of air equal to the dose of NPH insulin into a syringe. Inject the air into the NPH vial without touching the needle to the solution. Withdraw the needle and syringe without drawing up any insulin. This will create positive pressure in the NPH vial and make it easier to draw up later.
- Draw up the amount of air equal to the dose of regular (clear) insulin into the same syringe. Inject the air into the regular vial and invert the vial. Make sure the needle tip is below the fluid level and draw up slightly more than the dose of regular insulin. Tap the syringe gently to remove any air bubbles and push out any excess insulin to get the exact dose. Withdraw the needle and syringe from the regular vial.
- Reinsert the needle and syringe into the NPH vial without touching the needle to the solution. Invert the vial and draw up slightly more than the dose of NPH insulin. Tap the syringe gently to remove any air bubbles and push out any excess insulin to get the exact dose. Withdraw the needle and syringe from the NPH vial.
- Check that you have the correct doses of both insulins in one syringe. The total volume should be equal to the sum of both doses.
- Administer the dose within 5 to 10 minutes after drawing up because regular insulin binds to NPH and this decreases its action.
