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.

Explanation
a) Ineffective tissue perfusion: Though this might be a concern, the highest priority for an HIV-positive child is the risk of acquiring infections due to compromised immunity.
b) Risk for infection: HIV weakens the immune system, significantly increasing the risk of contracting infections. Preventing infections is the primary focus.
c) Risk for fluid volume deficit: While important, it's not the highest priority compared to the risk of infection due to HIV.
d) Ineffective thermoregulation: Not typically the primary concern for an HIV-positive child compared to the increased risk of infections due to the compromised immune system.
