A nurse is creating a plan of care for a child who is 3 years of age. Which of the following developmental milestones will help guide the nurse in developing a plan of care?

A. While 3-year-old children are beginning to understand simple safety rules, they do not reliably recognize hazards or consistently avoid dangerous situations. Planning care should not assume full understanding of safety risks, and the nurse must implement constant supervision and protective measures. B. At 3 years, children are in the preoperational stage of cognitive development, which means they are egocentric and have limited understanding of abstract rules. They may follow instructions inconsistently, so care plans should focus on simple, concrete guidance rather than expecting strict rule adherence. C. While 3-year-olds begin forming short sentences and can communicate basic needs, their conversations are usually brief, concrete, and self-focused. Planning care requires strategies that account for limited attention span and understanding, rather than assuming fully interactive conversation skills. D. By age 3, children can typically understand and respond to simple, concrete questions. This milestone is crucial for planning care because it allows the nurse to engage the child in basic instructions, assess understanding, and involve the child in age-appropriate care activities. For example, the nurse can ask the child simple questions about pain, comfort, or choices, which enhances cooperation and communication during procedures.
