A nurse is administering an intravenous (IV) infusion of 2 g cefotaxime dissolved in 100 mL of isotonic glucose solution to a client. The drop factor of the IV tubing is 15 drops/mL.
If the infusion time is 1 hr, what is the gt/min?

400 gt/min

6 gt/min

25 gt/min

9 gt/min

Answer and Explanation

The Correct Answer is C

The gt/min is 25.

This answer is correct because it is based on a simple formula and calculation. The nurse should use the following formula to calculate the gt/min:

gt/min = (Volume in mL x Drop factor in gt/mL) / Time in min

Plugging in the given values, the nurse should get:

gt/min = (100 mL x 15 gt/mL) / 60 min

gt/min = 25

Therefore, the gt/min is 25.

A. Draw up one-half of the NPH insulin followed by one-half of the regular insulin and repeat. B. Draw up one-half of the regular insulin followed by one-half of the NPH insulin and repeat. C. Draw up the NPH insulin into the insulin syringe followed by the regular insulin. D. Draw up the regular insulin into the insulin syringe followed by the NPH insulin.

Correct Answer is D

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.
