Correct Answer: D

Rationale: The recommended approach to intervention with children and youth focuses on evaluating the child's areas of competence and achievement, along with challenges. By understanding the child's strengths and competencies, interventions can be tailored to build upon these existing positive attributes. This approach fosters a positive self-image and encourages further development by capitalizing on the child's strengths.

Correct Answer: A

Rationale: The correct answer is A because an undescended testicle can reduce fertility. Even after surgical correction (orchiopexy), fertility rates may be reduced, especially when one testis remains undescended. The statement in choice B is incorrect as the testicle should have descended into the scrotum by the time the infant is 4-6 months old. While choice C is true that surgical correction can reduce the risk of testicular tumors, the question focuses on the father's understanding of the information presented, which is better reflected in choice A. Choice D is incorrect because the optimal time for surgical correction of an undescended testicle is typically around 6-18 months of age, not necessarily at the time of diagnosis.

Correct Answer: D

Rationale: It is important for the caregiver to instruct the parent to brush the child's teeth after administering ferrous sulfate to prevent staining of the teeth.
