Final answer:
The nurse should expect the normal finding of a presence of cerumen in the ear canal during an otoscopic examination of a child.
Step-by-step explanation:
The nurse should expect the normal finding of a presence of cerumen in the ear canal during an otoscopic examination of a child. Cerumen, also known as earwax, is a substance that is naturally produced by the ear to protect the ear canal and prevent foreign objects from entering.
The presence of clear fluid draining from the ear (option a) is not a normal finding and may indicate a possible ear infection or other ear-related issues. A red and bulging tympanic membrane (option b) is also not a normal finding and may indicate inflammation or infection. Absence of the tympanic membrane (option d) is a serious condition that requires immediate medical attention.
