The Nurse Explains to Parents Why an Adenoidectomy Is Sometimes

The nurse explains to parents why an adenoidectomy is sometimes indicated with the tonsillectomy. Which of the following is the nurse's best explanation?

A) "An adenoidectomy is justified when a child's enlarged adenoids block the flow of air through the nasal passages."
B) "Some surgeons prefer to take out the adenoids at the same time as the tonsillectomy because it saves the child from a second surgery."
C) "Without the tonsils to screen out foreign proteins, the adenoids are more easily infected."
D) "It is hard to take out the tonsils without removing the adenoids, because they often are adhered to each other."
