Epistaxis typically occurs in how many nostrils?

Explanation:
Epistaxis usually comes from the anterior nasal septum (Kiesselbach’s area), where a localized cluster of small vessels is prone to rupture. This makes the bleed typically occur from a single nostril, not both. Bilateral bleeding is less common and often suggests a posterior source or a more serious issue. So, the typical number of nostrils affected is one.
