What is the medical term for a nosebleed?

The correct term for a nosebleed is "epistaxis." This term specifically refers to the bleeding that occurs from the nasal cavity, which can happen for various reasons such as dry air, trauma, or underlying health conditions. Understanding medical terminology is crucial for effective communication in healthcare settings, especially for describing symptoms accurately.

The other terms provided are related to nasal conditions but do not describe a nosebleed. "Rhinorrhea" refers to a runny nose, typically involving mucus discharge, while "sinusitis" is the inflammation of the sinuses that can lead to pressure and pain but does not indicate bleeding. "Nasal congestion" describes the blockage of nasal passages, causing difficulty breathing through the nose. Each of these terms serves a different purpose in a medical context, highlighting the importance of precise language in identifying specific conditions.
