Care of the eyes, nose, and ears is important to prevent infections and maintain normal functioning. Key steps include cleaning the eyes from inner to outer corners with saline and a separate portion of cloth for each eye. The nose should be cleaned by having patients blow into tissues or using moistened cotton swabs gently rotated in the nostrils. Ears can be cleaned during baths by gently rotating a moistened washcloth. Regular cleaning and care of medical devices like hearing aids is also important.
