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 A
Explanation
Correct answer: A
Preschool-aged children (around 3 to 5 years old) have a limited understanding of death compared to older children or adults. They may not fully grasp the finality and permanence of death. They often have a more concrete and literal understanding of death.
A. Believing the death is punishment for bad behavior: Preschool-aged children (typically 3 to 5 years old) often have magical thinking and may believe that their thoughts or actions can cause events to happen. They may think that the death of a parent is a punishment for something they did or thought, reflecting their egocentric view of the world.
B. Recognizing the parent will never wake up: This understanding is more commonly seen in older children who have a more mature grasp of death. Preschool-aged children may not fully comprehend that death is irreversible and permanent.
C. While preschoolers might ask questions about the funeral out of curiosity, this is not the primary way they process or react to the death of a loved one. Their questions are often more about trying to understand what is happening rather than a genuine curiosity about the specifics of the service.
D. Understanding that everyone dies eventually: While preschool-aged children may have some understanding that death is a natural part of life, their comprehension of its full implications is limited. They may not fully grasp the universality of death and its inevitability for all living beings.
