A nurse is caring for a younger child with otitis media. The parents ask the nurse why children seem to get otitis media frequently, but adults do not. Which statement about the physiological differences between young children and adults would the nurse provide?
The eustachian tube is longer, wider, and more vertical in younger children
The eustachian tube is longer, narrower, and more vertical in younger children
The eustachian tube is shorter, wider, and more horizontal in younger children
The eustachian tube is shorter, narrower, and more horizontal in younger children
The Correct Answer is C
a) The eustachian tube is longer, wider, and more vertical in younger children: Inaccurate; a more vertical tube might be less prone to drainage issues.
b) The eustachian tube is longer, narrower, and more vertical in younger children: The opposite configuration of the pediatric eustachian tube.
c) The eustachian tube is shorter, wider, and more horizontal in younger children: The anatomy of the pediatric eustachian tube predisposes children to ear infections due to poor drainage and ventilation.
d) The eustachian tube is shorter, narrower, and more horizontal in younger children: Inaccurate; this configuration is less prone to issues related to otitis media.
