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 C
Explanation
The shoulder harnesses of the car seat should be adjusted to fit the infant properly. The straps should be positioned at or below the level of the infant's shoulders to ensure a secure fit and proper restraint.
Infants should always be placed in a rear-facing car seat in the back seat of the vehicle. If the car seat is placed in the front seat, the airbag should be turned off to prevent potential harm to the infant in case of airbag deployment.
Do not put a small cushion under the newborn's head for support: It is important to follow the manufacturer's guidelines for the specific car seat being used. Additional cushions or supports should not be added to the car seat as they can interfere with the proper fit and safety of the seat. The infant's head should be supported by the car seat itself.
Infants should be placed in a rear-facing car seat at a reclined angle of approximately 45 degrees. This helps to keep the infant's airway open and provides proper support for their head and neck.
Correct Answer is C
Explanation
When removing the dressing and cleaning the wound, it is important to start from the center of the wound and work towards the outer edges. This technique helps prevent contamination of the wound by minimizing the risk of dragging bacteria or debris from the surrounding skin into the wound.
The other options listed are not recommended for this specific procedure:
When removing the tape, it is generally recommended to pull it parallel to the skin surface rather than pulling from the center of the dressing. This technique reduces the risk of causing trauma or disrupting the wound.
While it is important to maintain aseptic technique during dressing changes, wearing sterile gloves is not necessary for a wet-to-dry dressing change. Clean, non-sterile gloves are typically sufficient for this procedure, as the dressing material itself is not sterile.
In a wet-to-dry dressing change, the dressing is typically applied moist and allowed to dry over time. Therefore, moistening the dressing before removal is not necessary. The primary goal is to remove the dry dressing, which may adhere to the wound bed, and then clean the wound before applying a fresh dressing.
