A nurse is preparing to collect data from a preschooler. Which of the following behaviors by the child indicates that he is ready to cooperate? (Select all that apply.)

A. Answers questions asked by the nurse: Responding verbally shows the child is engaged and able to understand and participate in the interaction, indicating readiness to cooperate during the assessment. B. Plays with toys in the examining room: While playing indicates comfort in the environment, it may also reflect distraction or avoidance rather than readiness to cooperate with the nurse’s instructions. Play alone is not a reliable indicator of cooperation. C. Makes eye contact with the nurse: Eye contact demonstrates attention and willingness to engage with the nurse, which is a positive sign that the child is prepared to follow directions during data collection. D. Allows the nurse to touch him on the arm: Tolerating touch shows trust and comfort with the nurse’s presence and interventions, signaling the child is ready to participate in the assessment. E. Sits on his parent's lap when the nurse enters the room: Sitting on a parent’s lap may indicate the child is seeking comfort and security rather than being ready to cooperate independently. This behavior alone does not confirm readiness for assessment.
