Final answer:
The nurse could be at risk of a malpractice suit if they perform CPR without proper training.
Step-by-step explanation:
In this scenario, the nurse could be at risk of a malpractice suit if they perform CPR without proper training. While the state may have a Good Samaritan law that offers some protection to those providing emergency care, it generally requires that the person providing the care act within their training and scope of practice. If the nurse performs CPR without proper training and inadvertently causes harm to the victim, they could be held liable for negligence.
