Why are infants more susceptible to otitis media?
Infants are in a supine or prone position most of the time.
Sucking on a nipple creates middle ear pressure.
They have increased susceptibility to upper respiratory tract infections.
The eustachian tube is short, straight, and wide.
The Correct Answer is D
Choice A reason: A supine or prone position may allow milk or secretions to pool, but this is not the primary reason for otitis media susceptibility. Positioning contributes indirectly by facilitating fluid reflux, but anatomical factors are more significant in infants.
Choice B reason: Sucking on a nipple does not significantly create middle ear pressure. While bottle-feeding in a supine position may allow fluid reflux into the eustachian tube, this is secondary to the anatomical structure of the tube itself.
Choice C reason: Infants are prone to upper respiratory infections due to immature immunity, which can lead to otitis media. However, this is a contributing factor, not the primary anatomical reason, as infections exploit the eustachian tube’s structure to cause middle ear inflammation.
Choice D reason: Infants’ eustachian tubes are shorter, straighter, and wider than in adults, allowing easier passage of bacteria from the nasopharynx to the middle ear. This anatomical feature impairs drainage and ventilation, increasing susceptibility to fluid accumulation and infection, making it the primary cause.

Correct Answer is D
Explanation
Choice A reason: Stopping antibiotics when symptoms resolve risks incomplete bacterial eradication, leading to recurrent or resistant otitis media. Antibiotics must be taken for the full course to ensure all pathogens (e.g., Streptococcus pneumoniae) are eliminated, preventing chronic infection or complications.
Choice B reason: Sharing antibiotics with siblings is dangerous, as it may lead to incorrect dosing, inappropriate treatment, or antibiotic resistance. Each child requires a specific prescription based on their condition, weight, and bacterial susceptibility, making this an unsafe practice.
Choice C reason: Giving antibiotics with milk may reduce absorption for some drugs (e.g., amoxicillin), as calcium can bind to certain antibiotics, decreasing bioavailability. This statement indicates a misunderstanding, as water is typically recommended to ensure optimal drug absorption.
Choice D reason: Administering the full course of antibiotics ensures complete eradication of bacteria causing otitis media, preventing recurrence or resistance. This reflects proper understanding, as completing the prescribed regimen targets pathogens like Haemophilus influenzae, ensuring effective treatment and reducing complication risks.
