Answer: If a friend has a bloody nose, she should pinch her nostrils and lean forward.
Explanation:
This is the recommended first aid technique for treating a nosebleed. Here's why:
- Pinching the nostrils: By pinching the nostrils, pressure is applied to the blood vessels in the nose. This pressure helps to stop the bleeding by slowing down the flow of blood from the vessels that are likely the source of the bleed.
- Leaning forward: Leaning forward helps prevent the blood from flowing down the throat, which can cause nausea, vomiting, or choking. It also allows the blood to drip out of the nose rather than flowing backward into the throat and potentially causing irritation or aspiration.
So, the correct action is to pinch the nostrils and lean forward to control the bleeding effectively and minimize discomfort or complications.
