A home health nurse is reinforcing teaching about home safety with an older adult client who lives alone. Which of the following client statements indicates an understanding of the teaching?

A. "Provide informational updates to members of the media" is incorrect. This task typically falls under the responsibility of the hospital’s public relations or communications team. Nurses do not usually handle media updates in the context of mass casualty events.

B. "Assist in discharging stable clients to home" is correct. During a mass casualty event, it is important to make room for incoming patients. Discharging stable patients helps free up beds and resources for those who need immediate care.

C. "Delegate tasks to emergency health care specialists" is incorrect. While nurses may delegate some tasks, the nurse’s primary responsibility in this scenario would be managing care within the medical-surgical unit, not directing emergency health care specialists.

D. "Determine the acuity and number of casualties arriving at the facility" is incorrect. This task is generally managed by triage teams or emergency management staff who assess incoming patients at the point of injury or arrival at the facility.

A. Injecting 15 units of air into the regular insulin vial is correct. When drawing up two types of insulin, the nurse should first inject air into the NPH (cloudy) insulin vial without withdrawing the medication. Then, the nurse should inject air into the regular (clear) insulin vial before withdrawing the regular insulin. This prevents contamination and maintains proper insulin mixing procedures.

B. Placing the cap over the needle is incorrect. Once insulin preparation has started, recapping the needle is unnecessary and increases the risk of contamination or needlestick injury.

C. Verifying the dosage with another nurse is incorrect at this stage. Dosage verification should be done after the correct amounts of insulin are drawn into the syringe, not before.

D. Withdrawing 10 units of NPH insulin is incorrect. The nurse should first withdraw the regular (clear) insulin before drawing up the NPH (cloudy) insulin to avoid contaminating the regular insulin with the longer-acting insulin.
