Answer to Question 1

ANS: D
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. The abdominal respirations and lowered pulse and respiratory rate of toddlers do not affect their susceptibility to infection. The defense mechanisms are more efficient compared with those of infancy.

Answer to Question 2

ANS: B, C, E
Certain groups of infants are at increased risk for SIDS: those with low birth weight, low Apgar scores, or recent viral illness, and those of male sex. Breastfed infants and infants of average or above-average weight are not at higher risk for SIDS.
