A nurse is mixing regular insulin and NPH insulin in the same syringe prior to administering it to a client who has diabetes mellitus.
Which of the following actions should the nurse take first?

Inject air into the NPH vial.

Withdraw the NPH insulin from the vial.

Withdraw the regular insulin from the vial.

Inject air into the regular insulin vial.

Answer and Explanation

The Correct Answer is A

The correct sequence for mixing regular insulin and NPH insulin in the same syringe is important to ensure proper dosing. The nurse should follow these steps:

Inject air into the NPH (intermediate-acting) insulin vial: Injecting air into the NPH vial first helps to equalize the pressure in the vial, making it easier to withdraw the insulin later. This step is done first to avoid contaminating the regular insulin vial with NPH insulin.
Inject air into the regular insulin vial: Next, inject an amount of air equal to the intended regular insulin dose into the regular insulin vial.This also helps to equalize the pressure and makes it easier to withdraw the insulin.
Withdraw the regular insulin from the vial : The nurse should withdraw the regular insulin first because it is clear and not contaminated. This prevents any NPH insulin from mixing into the regular insulin vial.
Withdraw the regular insulin from the vial: Finally, the nurse withdraws the NPH insulin. Since the regular insulin has already been drawn up, there is no risk of contaminating the regular insulin with NPH insulin.

This sequence ensures that you don't contaminate the vials, and you accurately withdraw the appropriate doses of each insulin type.

Correct Answer is B

Explanation

The client has a negative sputum culture. This indicates that the client is adhering to the medication regimen because a negative sputum culture means that the client is no longer infectious and has cleared the tuberculosis bacteria from their lungs.

Choice A is wrong because testing negative for HIV does not indicate that the client is adhering to the medication regimen for tuberculosis. HIV testing is not related to tuberculosis treatment.

Choice C is wrong because having a positive purified protein derivative test does not indicate that the client is adhering to the medication regimen for tuberculosis.

A positive PPD test means that the client has been exposed to tuberculosis, but it does not indicate whether the client has an active or latent infection. Choice D is wrong because having liver function test results within the expected reference range does not indicate that the client is adhering to the medication regimen for tuberculosis.

Liver function tests are used to monitor for possible adverse effects of isoniazid and rifampin, which can cause hepatotoxicity, but they do not reflect the effectiveness of the treatment.

A. Apply pressure to the IV site. B. Elevate the extremity. C. Slow the infusion rate. D. Flush the IV catheter.

Correct Answer is B

Explanation

This will help reduce swelling and discomfort caused by the infiltration of fluid into the tissues. Elevating the extremity also promotes venous return and prevents further fluid accumulation.

Choice A is wrong because applying pressure to the IV site can increase the risk of tissue damage and infection.

Pressure can also obstruct blood flow and cause thrombophlebitis.

Choice C is wrong because slowing the infusion rate will not stop the infiltration of fluid into the tissues.

Slowing the infusion rate can also delay the delivery of medication or fluid to the client.

Choice D is wrong because flushing the IV catheter can worsen the infiltration of fluid into the tissues.

Flushing the IV catheter can also introduce air or bacteria into the bloodstream and cause complications.

Normal ranges for peripheral IV infusion are dependent on the type and volume of fluid, the size and location of the catheter, and the condition of the client. Generally, peripheral IV infusion rates should not exceed 100 mL/hr for adults and 60 mL/hr for children.
