What does the term "emesis" mean?

The term "emesis" refers specifically to the act of vomiting. In medical terminology, it is derived from the Greek word "emein," which means "to vomit," and is commonly used in healthcare settings to describe the process whereby the contents of the stomach are expelled through the mouth. Understanding this definition is crucial for healthcare professionals, including CNAs, as it is important to accurately report symptoms and conditions related to a patient’s health status. In contrast, the other options—diarrhea, constipation, and nausea—refer to different gastrointestinal conditions, making it essential to distinguish them from "emesis" to ensure proper communication and care in clinical environments.
