A parent and 4-year-old child are waiting in an exam room when the nurse enters and greets them. Which activity that the nurse observes the child doing would best demonstrate the primary developmental task of the preschool-age child, according to Erikson?
Correct Answer: C
Rationale: The correct answer is C. According to Erikson, the primary task of a preschool-aged child is to explore and assert control over their environment. This behavior is demonstrated by the child opening drawers, pulling out supplies, and examining them, showcasing curiosity and exploration. Choices A, B, and D do not align with the primary developmental task of a preschool-age child according to Erikson. Reading a book and singing a song are more passive activities, while roughhousing with the parent does not directly relate to exploration and asserting control over the environment.
