This is the first CNA Legal and Ethical Behavior Practice Test. Here, you can practice Legal and Ethical Behavior questions. You will be able to see correct & incorrect answers for each question. As a professional working in the healthcare setting, it is important for the nursing assistant to know the rules and regulations surrounding their job description. Performing duties outside of one’s scope of practice or performing duties incorrectly could result in losing a job or even legal action. Abuse, assault, negligence, and invasion of privacy are all acts which are considered unethical and could lead to big trouble for the nursing assistant.
