True or False: It is recommended for someone with a nosebleed to lean their head back.

Leaning the head back during a nosebleed is not advisable because it can cause blood to flow down the throat, which may lead to swallowing blood or even aspiration into the lungs. The correct approach is to lean slightly forward, which helps to prevent blood from entering the throat and minimizes the risk of choking or gagging. This method also allows for better visualization and management of the bleeding.

For individuals experiencing a nosebleed, it is generally recommended to pinch the nostrils together and breathe through the mouth while applying gentle pressure for a sustained period. By taking these measures, the bleeding can be controlled more effectively and safely. Therefore, the recommendation is to not lean the head back.
