Which factor is most important in predisposing toddlers to frequent infections such as otitis media, tonsillitis, and upper respiratory tract infections?
Respirations are abdominal
Pulse and respiratory rates are slower than those in infancy
Defense mechanisms are less efficient than those during infancy
The presence of short, straight internal ear/throat structures and large tonsil/adenoid lymph tissue
The Correct Answer is D
This is because toddlers continue to have the short, straight internal ear canal of infants.
The lymphoid tissue of the tonsils and adenoids continues to be relatively large. These two anatomic conditions combine to predispose the toddler to frequent infections.
Choice A is wrong because respirations are abdominal. This does not affect the susceptibility to infection.
Choice B is wrong because pulse and respiratory rates are slower than those in infancy. This also does not affect the susceptibility to infection.
Choice C is wrong because defense mechanisms are less efficient than those during
infancy. This is not true, as the defense mechanisms are more efficient compared with those of infancy.
