A nurse is preparing to administer insulin to a client with diabetes mellitus. The nurse draws up 10 units of regular insulin and 20 units of NPH insulin in the same syringe. Which of the following actions should the nurse take next?

Inject air into the NPH vial

Inject air into the regular vial

Withdraw NPH insulin from the vial

Withdraw regular insulin from the vial

Answer and Explanation

The Correct Answer is B

When mixing two types of insulin in one syringe, the nurse should follow the mnemonic RN or "regular before NPH". This means that the nurse should first inject air into the NPH vial, then inject air into the regular vial, then withdraw regular insulin from the vial, and finally withdraw NPH insulin from the vial. This order prevents contamination of the regular insulin with NPH insulin and ensures accurate dosing.

Incorrect choices:

a) Inject air into the NPH vial: This is correct, but it is not the next action. The nurse should inject air into the NPH vial before drawing up any insulin.

c) Withdraw NPH insulin from the vial: This is incorrect and can lead to a medication error. The nurse should withdraw NPH insulin after withdrawing regular insulin.

d) Withdraw regular insulin from the vial: This is correct, but it is not the next action. The nurse should inject air into the regular vial before withdrawing regular insulin.

Correct Answer is D

Explanation

All of the instructions are correct and important for a client who is taking digoxin. Digoxin is a cardiac glycoside that can improve the contractility and rhythm of the heart. However, it can also cause serious side effects, such as bradycardia, arrhythmias, or toxicity.

A. Flush the tube with 30 mL of water B. Check the placement of the tube C. Clamp the tube for 30 minutes D. Elevate the head of the bed

Correct Answer is B

Explanation

The nurse should check the placement of the tube before administering any medication or fluid via an NG tube. This can prevent aspiration, infection, or injury to the client. The nurse can check the placement by aspirating gastric contents and measuring the pH, or by using a carbon dioxide detector.

Incorrect choices:

a) Flush the tube with 30 mL of water: Flushing the tube with water is correct, but it is not the next action. The nurse should flush the tube before and after administering the medication to prevent clogging and ensure delivery.

c) Clamp the tube for 30 minutes: Clamping the tube for 30 minutes is incorrect and can cause complications. The nurse should not clamp the tube unless ordered by the provider. Clamping the tube can increase the risk of reflux, aspiration, or tube displacement.

d) Elevate the head of the bed: Elevating the head of the bed is correct, but it is not the next action. The nurse should elevate the head of the bed at least 30 degrees before and during the administration of the medication to prevent aspiration and promote gastric emptying.
