A 17-year-old girl is hospitalized for appendicitis, and her mother asks the nurse why she is so needy and acting like a child. The best response of the nurse is that in the hospital, adolescents

A) have separation anxiety.
B) rebel against rules.
C) regress because of stress.
D) want to know everything.

Regression to an earlier stage of development is a common response to stress. Separation anxiety is most common in infants and toddlers. Rebellion against hospital rules is usually not an issue if the adolescent understands the rules and would not create childlike behaviors. An adolescent may want to "know everything" with their logical thinking and deductive reasoning, but that would not explain why they would act like a child.
