Final answer:
An untrained Nursing Assistant should call emergency services and seek a trained individual to perform CPR or use an automated external defibrillator (AED) if available; they should not attempt full CPR without guidance to avoid causing injury.
Step-by-step explanation:
If a Nursing Assistant (NA) is in an emergency situation and has not been trained in CPR, the NA should first call for help, such as dialing emergency services, and try to find someone who is trained in CPR to assist. If no one trained is available, the untrained NA may be guided to perform compression-only CPR if instructed by emergency services, as this is better than doing nothing. However, they should not attempt full CPR unless instructed to do so, as doing it improperly can cause injury. The NA can also look for an automated external defibrillator (AED), which often have verbal instructions and can be crucial in the first few minutes following a cardiac event.
It's important to act swiftly but also safely, ensuring not to put yourself or the individual in further danger. Assess the situation clearly and look for safe and effective ways to assist while emergency services are on their way.
