If the blow were to say break his nose that is serious bodily injury and now you are looking at a Class B felony, Assault 2. If the blow was still serious and resulted in bodily injury but not as serious as an Assault 1 or 2 then you have a Class C felony, assault 3.
The nose is pretty complex, though. The lining tissues if the nose and sinuses is called mucosa. This tissue is really quite thin and can dry out, crack and bleed slightly. The sinuses can also bleed, which can cause bloody nasal secretions or boogers. Trauma to the nose, big or small can do it too. Hope this helps.
