Rationale: At 2 months, infants are most stimulated by visual and auditory activities, such as a music box or soft mobiles. These activities help in sensory development and are appropriate for this age.

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.

Correct Answer: A

Rationale: Baby powder can be inhaled by the infant and cause respiratory distress. Toys should be inspected to prevent choking hazards. Allowing an infant to take a bottle to bed can increase the risk of aspiration, and hard foods like teething biscuits should be given with caution.

Correct Answer: B

Rationale: Adolescents often seek guidance and support from their peers. Setting up a meeting with older teens who are effectively managing chronic renal failure can provide the 14-year-old with motivation, encouragement, and practical advice on how to handle their treatment regimen. This peer support can positively influence the non-compliant adolescent, making choice B the most likely intervention to improve compliance. Choices A and C may not address the peer influence aspect of adolescent behavior, while choice D focuses on punitive measures rather than addressing the underlying reasons for non-compliance.

Correct Answer: C

Rationale: FTT is characterized by weight that falls below the 10th percentile, often accompanied by delayed developmental milestones and poor feeding habits. Regularity in activities and preference for solid food over milk or formula are less commonly associated with FTT.
