What does emesis refer to in medical terms?

Emesis is a medical term that specifically refers to the act of vomiting. It indicates the expulsion of the contents of the stomach through the mouth, often as a result of nausea or a response to illness, food intolerances, or other health issues. Understanding this terminology is crucial in medical documentation and communication, as it provides clear information about a patient's condition.

The other options refer to different medical conditions: painful urination relates to dysuria, difficulty breathing is known as dyspnea, and a bruise is referred to as a contusion. Each of these terms has its distinct meaning, which differentiates them from emesis, thereby reinforcing the clarity and accuracy needed in medical terminology.
