Rationale: Improving the child's competence and creating a positive environment is the most effective strategy to promote positive behavior in children. This approach focuses on enhancing the child's skills and abilities while fostering a supportive and encouraging atmosphere.

Rationale: In managing minimal change nephrotic syndrome (MCNS) in children with pitting edema, corticosteroids are the mainstay of treatment. Corticosteroids help reduce inflammation and decrease proteinuria, addressing the underlying cause of MCNS.

Correct Answer: B

Rationale: In nephrotic syndrome, edema is a common symptom that is generalized and not easily noticeable, even by parents. However, an early sign that can be assessed by the nurse is periorbital edema, which refers to swelling around the eyes. This can be an initial indicator of nephrosis and may prompt further evaluation and intervention.
