A nurse is caring for a client who has a prescription for NPH insulin 10 units and regular insulin 15 units subcutaneously. After injecting 10 units of air into the NPH insulin vial, which of the following actions should the nurse take next?
Verify the dosage with another nurse.
Inject 15 units of air into the regular insulin vial.
Withdraw 10 units of NPH insulin.
Place the cap over the needle.
The Correct Answer is B
This step is part of the process when mixing NPH and regular insulin in a single syringe. After injecting air into the NPH insulin vial, you should inject an equal amount of air (in this case, 15 units) into the regular insulin vial to maintain pressure balance. This allows for easy withdrawal of the prescribed doses of each insulin type in the same syringe without causing a vacuum in the vials.
After injecting air into the NPH insulin vial (step 1), the nurse should proceed to inject air into the regular insulin vial (step 2) before withdrawing the insulin doses in the subsequent steps.
Verifying the dosage with another nurse is not necessary in this step, as it is done prior to drawing up the insulin. However, it is good practice to have another nurse double-check the dosage before administration.
Injecting air into the regular insulin vial is not required at this stage. It is only necessary when withdrawing the regular insulin dose.
Placing the cap over the needle should be done after withdrawing the desired dose of insulin and before administering it to the client for safety and to prevent needlestick injuries.
The correct sequence when mixing NPH and regular insulin in a single syringe is as follows:
- Inject air into the NPH insulin vial (in this case, 10 units of air).
- Inject air into the regular insulin vial (in this case, 15 units of air).
- Withdraw the prescribed dose of NPH insulin (10 units) from the NPH vial.
- Withdraw the prescribed dose of regular insulin (15 units) from the regular insulin vial.
So, after injecting air into the NPH insulin vial (step 1), the nurse should proceed to inject air into the regular insulin vial (step 2) before withdrawing the insulin doses in the subsequent steps.

Correct Answer is D
Explanation
Explanation
D, Wash hands with soap and water for 20 seconds
Hand hygiene is a critical practice in preventing the transmission of infections in healthcare settings. Here's why the other options are incorrect:
Wearing sterile gloves when in contact with body fluids in (option A) is incorrect because it is important for preventing the transmission of pathogens, but it is not directly related to hand hygiene. Hand hygiene refers to the cleaning of hands to remove pathogens, and sterile gloves provide a barrier to protect the healthcare worker and the patient.
B. Using an alcohol-based cleanser when hands are visibly soiled in (option B) is not recommended. Alcohol-based cleansers are effective in killing many types of germs, but they are not as effective in removing visible dirt, blood, or body fluids. In such cases, it is important to wash hands with soap and water to thoroughly clean them.
Artificial nails should not be worn when performing direct client care in (option C). They can harbor and transmit pathogens and make it more difficult to effectively clean hands. The Centres for Disease Control and Prevention (CDC) recommends that healthcare workers maintain short, clean, and natural nails without the use of artificial nails or nail extensions.
Correct Answer is D
Explanation
Range-of-motion exercises are within the scope of practice for an AP and do not require specialized nursing knowledge or assessment skills. The AP can assist the client in performing these exercises to promote circulation, maintain joint mobility, and prevent complications associated with immobilization.
Determining the circulation status of the affected extremities, evaluating the need for restraints, and providing education to the client's family about the purpose of restraints require nursing assessment, critical thinking, and communication skills. These tasks should be performed by a licensed nurse who can make clinical judgments and ensure the safety and well-being of the client.
