Step-by-step explanation:
To visualize the ear canal in a 2-year-old, you would pull the pinna down and back. The pinna is the visible part of the ear, and by gently pulling it down and back, you can straighten the ear canal for better visualization. This technique is often used when examining a young child's ear to get a clear view of the eardrum and detect any abnormalities.
By pulling the pinna down and back, you can also straighten the ear canal, which can help with the administration of ear drops or other ear medications, if necessary. It's important to be gentle and cautious when performing this maneuver to ensure the comfort and safety of the child.
