Step-by-step explanation:
If a nursing assistant is in an emergency situation but has not been trained to perform CPR, she should focus on removing the person from the dangerous environment or situation as quickly as possible. CPR should only be administered by individuals who have been properly trained, as it can result in injury or further harm if performed incorrectly. It is important for the nursing assistant to notify a trained professional or call for emergency medical assistance to provide the necessary aid to the individual in need.
