Epistaxis, or nosebleeds, are common and usually not serious. They are often caused by dry air irritating the nasal membranes. Nosebleeds can also be triggered by colds, allergies, high blood pressure, medications, and injuries. Treatment involves sitting upright, pinching the nose to apply pressure, and seeking medical care if bleeding does not stop. If bleeding is severe or persistent, a healthcare provider may insert nasal packing to stop the bleeding. Nursing care focuses on monitoring for complications and providing comfort measures.
