The patient needs both regular insulin and NPH insulin to be administered subcutaneously. The nurse will mix both insulins in the same syringe.
What is the correct technique for preparing this insulin order?
Draw up one-half of the NPH insulin followed by one-half of the regular insulin and repeat.
Draw up one-half of the regular insulin followed by one-half of the NPH insulin and repeat.
Draw up the NPH insulin into the insulin syringe followed by the regular insulin.
Draw up the regular insulin into the insulin syringe followed by the NPH insulin.
The Correct Answer is D
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.

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) x Flow factor (gt/mL)) / Time (min) x 60 min/h
Since the total volume is 50 mL, the flow factor is 1 gt/mL, and the time is 15 minutes, plug in these values into the formula:
Infusion rate (mL/h) = (50 mL x 1 gt/mL) / 15 min x 60 min/h
Simplify and solve for the infusion rate:
Infusion rate (mL/h) = 200 mL/h
Therefore, the nurse should set the IV pump to deliver **200 mL/h** to infuse Regian 10 mg over 15 minutes.
Correct Answer is B
Explanation
To find the maximum number of tablets the patient may have in 24 hours, you need to calculate the following:
- The number of doses the patient may have in 24 hours using the formula: Number of doses = 24 hours / Dosing interval (hours)
- The total dose of ibuprofen in milligrams (mg) for 24 hours using the formula: Total dose (mg) = Number of doses x Prescribed dose (mg)
- The number of tablets of ibuprofen using the formula: Number of tablets = Total dose (mg) / Strength per tablet (mg)
First, use the formula for number of doses to find how many times the patient may take ibuprofen in 24 hours:
Number of doses = 24 hours / Dosing interval (hours)
Since the dosing interval is 6 hours, plug in this value into the formula:
Number of doses = 24 hours / 6 hours
Simplify and solve for the number of doses:
Number of doses = 4
Next, use the formula for total dose to find the amount of ibuprofen in milligrams for 24 hours:
Total dose (mg) = Number of doses x Prescribed dose (mg)
Since the number of doses is 4 and the prescribed dose is 600 mg, plug in these values into the formula:
Total dose (mg) = 4 x 600 mg
Simplify and solve for the total dose:
Total dose (mg) = 2400 mg
Then, use the formula for number of tablets to find how many tablets of ibuprofen are needed:
Number of tablets = Total dose (mg) / Strength per tablet (mg)
Since the total dose is 2400 mg and the strength per tablet is 200 mg, plug in these values into the formula:
Number of tablets = 2400 mg / 200 mg
Simplify and solve for the number of tablets:
Number of tablets = 12
Therefore, the maximum number of tablets the patient may have in 24 hours is **12**.
