A nurse is providing anticipatory guidance about child development to the parents of a preschooler. Which of the following developmental tasks should the nurse include as being expected of a preschooler?

A. Controlling impulsive feelings is more typical of school-age children (around 6–12 years), as they develop greater self-regulation and emotional control. B. Building collections or hobbies is more common in school-age children, who have increased attention span and interest in structured activities. C. Expressing a need for privacy usually emerges in later childhood, around the school-age years, as children become more aware of personal boundaries. D. Participating in imaginary play is a hallmark of preschool development (ages 3–5 years). At this stage, children engage in pretend play, role-playing, and creative activities that support social, cognitive, and emotional growth.
