When caring for a child with epistaxis, which action should the nurse take first?

In the management of epistaxis, the primary goal is to stop the bleeding effectively while ensuring the child's safety. Applying pressure at the bridge of the child's nose is the most appropriate first action. This technique helps to constrict the blood vessels in the nasal area, which can quickly reduce blood flow and help control the bleeding.

Applying pressure is a widely recommended first aid measure for nasal bleeding and is usually effective in most cases. Other actions, such as applying ice or having the child sniff saline solutions, are less direct in addressing the bleeding itself. Encouraging a child to tilt their head back may lead to blood flowing down the throat, which can pose a choking hazard and complicate the situation. Therefore, applying pressure at the bridge of the nose is the best and most effective initial intervention in managing epistaxis in children.
