Epistaxis, or nosebleed, is caused by rupture of tiny blood vessels in the nasal cavity. It is common and can occur in any age group. Bleeding most often originates from an area in the front of the nose called Little's area. Epistaxis can be anterior, originating in the front part of the nose, or posterior, originating in the back part. Causes include local trauma, infections, medications, and systemic conditions like high blood pressure. Treatment depends on the location and severity of bleeding and may include pressure, cauterization, nasal packing, or medication. Nursing care focuses on monitoring vital signs, controlling bleeding, preventing anxiety, and providing discharge teaching to prevent future episodes.
