The Mother of a 2-Year-Old Is Concerned Because Her Son

The mother of a 2-year-old is concerned because her son has had three ear infections in the past year. What would be an appropriate response by the nurse?

A) "It is unusual for a small child to have frequent ear infections unless something else is wrong."
B) "We need to check the immune system of your son to determine why he is having so many ear infections."
C) "Ear infections are not uncommon in infants and toddlers because they tend to have more cerumen in the external ear."
D) "Your son's eustachian tube is shorter and wider than yours because of his age, which allows for infections to develop more easily."
