What is commonly referred to as the stomach flu?

The term "stomach flu" is commonly used to describe gastroenteritis, which is an inflammation of the stomach and intestines. This condition typically results from viral or bacterial infections and is characterized by symptoms such as nausea, vomiting, diarrhea, abdominal cramps, and sometimes fever. Although it is called the stomach flu, it is important to note that it is not caused by the influenza virus, which primarily affects the respiratory system.

Gastroenteritis is most often caused by infectious agents, including norovirus and rotavirus, and can spread easily through contaminated food or water, as well as close contact with infected individuals. Understanding this condition is vital for nursing assistants, as they may encounter patients displaying symptoms of gastroenteritis and need to provide appropriate care and support.

The other options listed pertain to different medical conditions that do not relate to the symptoms commonly associated with what people refer to as "stomach flu."
