A community health nurse is developing a brochure about hypertension.

Which of the following actions should the nurse take?

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.

Correct answer: C

A.Opening the dampers of fireplaces: This instruction is not appropriate during an outdoor chemical disaster. Opening the dampers of fireplaces can allow contaminated air from outside to enter the home, increasing the exposure to hazardous substances. It is best to avoid introducing outdoor air into the home during such incidents.

B. Turning on ceiling fans and air conditioners: This instruction is also not recommended during an outdoor chemical disaster. Turning on fans and air conditioners can potentially circulate contaminated air within the home, leading to increased exposure. It is best to turn off fans and air conditioners during such incidents and focus on evacuating the area.

C. Covering heat registers with plastic and tape: Covering heat registers with plastic and tape would help seal off potential entry points for contaminated air, reducing the risk of indoor contamination.

D.In the case of a nearby outdoor chemical disaster, it is usually safer to stay indoors and seal the home rather than exit, as going outside could increase exposure to the harmful chemicals.
