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
This is another dosage calculation problem. To solve it, we need to use the formula:
Caloric need ÷ Calories per mL 1000 = Formula per day
In this case, the caloric need is 2250 calories, and the calories per mL is 2000/1000 = 2. Plugging these values into the formula, we get:
2250 ÷ 2 × 1000 = 1125
Therefore, the client would need **1125 mL** of formula per day to meet the calorie requirements.
Correct Answer is A
Explanation
To find the number of capsules of amoxicillin required for 5 days, you need to calculate the following:
- The total dose of amoxicillin in milligrams (mg) for 5 days using the formula: Total dose (mg) = Prescribed dose (mg) x Frequency (times/day) x Duration (days)
- The number of capsules of amoxicillin using the formula: Number of capsules = Total dose (mg) / Strength per capsule (mg)
First, use the formula for total dose to find the amount of amoxicillin in milligrams for 5 days:
Total dose (mg) = Prescribed dose (mg) x Frequency (times/day) x Duration (days)
Since the prescribed dose is 250 mg, the frequency is 3 times per day, and the duration is 5 days, plug in these values into the formula:
Total dose (mg) = 250 mg x 3 times/day x 5 days
Simplify and solve for the total dose:
Total dose (mg) = 3750 mg
Next, use the formula for number of capsules to find how many capsules of amoxicillin are needed:
Number of capsules = Total dose (mg) / Strength per capsule (mg)
Since the total dose is 3750 mg and the strength per capsule is 250 mg, plug in these values into the formula:
Number of capsules = 3750 mg / 250 mg
Simplify and solve for the number of capsules:
Number of capsules = 15
Therefore, the client needs **15 capsules** of amoxicillin for 5 days.
