A nurse is reinforcing teaching about car seat safety with a parent of a newborn. Which of the following statements by the parent indicates an understanding of the teaching?

Applying pressure with gauze helps to control bleeding and promote clotting. The other statements are not accurate or appropriate for circumcision care: "I will apply antibiotic ointment to my baby's penis" is not recommended for Plastibell circumcision. The use of antibiotic ointment is not typically necessary or recommended unless specifically advised by the healthcare provider.

"I will wipe away yellow crusts that form around the incision" should not be done as it may disrupt the healing process. Yellow crusts are a normal part of the healing process and should be left undisturbed.

"I will make sure that my baby's diaper is applied snugly" is unrelated to circumcision care. While proper diapering is important for maintaining hygiene, it does not specifically address the care of the circumcision site.

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:

1. Inject air into the NPH insulin vial (in this case, 10 units of air).
2. Inject air into the regular insulin vial (in this case, 15 units of air).
3. Withdraw the prescribed dose of NPH insulin (10 units) from the NPH vial.
4. 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.
