Which of the following scenarios illustrates nonfeasance?

Nonfeasance refers to the failure to take action when there is an obligation to do so. In the context of athletic training, this specifically means not providing care or assistance in a situation where it is required.

In this scenario, the act of failing to administer first aid represents a clear example of nonfeasance. When an athlete is injured or in need of assistance, the expectation is that a trained professional should step in to provide the necessary care. By not administering first aid, the trained individual is neglecting their responsibility to ensure the safety and well-being of the athlete.

The other scenarios illustrate different concepts related to negligence or malpractice: performing CPR incorrectly indicates improper action, providing incorrect medical advice also suggests taking inappropriate action, and ignoring an athlete's symptoms may involve a lack of proper assessment but does not directly represent the inaction described by nonfeasance. The focus of nonfeasance is specifically on the absence of necessary action.
