Choice A rationale:

A history of frequent episodes of otitis media is important to inquire about because recurrent ear infections are a common sign of otitis media.

Children who have experienced multiple episodes of otitis media are at a higher risk for developing the condition again.

This information helps the nurse assess the child's susceptibility to ear infections and guides further evaluation and treatment decisions.

Choice B rationale:

Previous upper respiratory tract infections are relevant to the child's overall health but are not specific symptoms of otitis media.

Otitis media can be a complication of upper respiratory infections, but the presence of previous infections alone does not confirm otitis media.

Choice C rationale:

Exposure to loud noise as a daily occurrence is not a symptom of otitis media.

Otitis media is an inflammation of the middle ear, commonly caused by bacterial or viral infections, and is not related to exposure to loud noises.

Choice D rationale:

A feeling of fullness or pressure in the ear can be associated with otitis media, but it is a nonspecific symptom that can occur in various ear conditions.

While it may raise suspicion, it is not a definitive sign of otitis media.

Choice E rationale:

Immunization history of the child is important for the child's overall health, but it is not a specific symptom of otitis media.

Immunizations do not directly influence the development or presence of otitis media.
