Final answer:
The olfactory (I) nerve is responsible for the sense of smell. In infants, children, and adolescents, expected findings of the olfactory nerve include the ability to recognize common smells, such as coffee or mint, which indicates proper functioning of the olfactory system. Anosmia can occur, but the olfactory nerve has the ability to regenerate.
Step-by-step explanation:
The olfactory (I) nerve is responsible for the sense of smell. In infants, children, and adolescents, the expected findings of the olfactory nerve include the ability to recognize common smells, such as coffee or mint, which indicates proper functioning of the olfactory system. Loss of the sense of smell, known as anosmia, can occur due to blunt trauma to the head or aging. However, in these age groups, the olfactory nerve has the ability to regenerate and new neurons can eventually reconnect, leading to the possibility of temporary anosmia.
