A nurse is reviewing discharge instructions with the caregiver of a 3-year-old child who underwent nephrectomy for Wilms' tumor. Which statement by the caregiver best demonstrates understanding of the necessary activity precautions to protect the child's remaining kidney?

A. Limiting social interactions to reduce overstimulation during early infancy: While minimizing overstimulation is sometimes necessary, limiting social interaction can hinder the development of trust and attachment, which are critical psychosocial milestones at 4 months.

B. Responding promptly and calmly when the infant cries to foster trust and security: At 4 months, infants are developing a sense of trust versus mistrust. Consistent, sensitive responses to the infant’s needs help establish secure attachment and a foundation for healthy psychosocial development.

C. Encouraging the infant to explore objects independently without interaction: Independent exploration is limited at this age, and social interaction is crucial for developing attachment and communication skills, so this does not support expected psychosocial milestones.

D. Allowing the infant to cry for extended periods to encourage self-soothing: Infants this young are not developmentally capable of self-soothing for long periods. Ignoring their cries can undermine trust and security, which are central at this stage.

A. Delayed motor development:Muscular dystrophy is characterized by progressive muscle degeneration that often presents in early childhood. Delayed milestones such as late walking, difficulty running, or frequent falls are common early assessment findings.

B. Lung defects:Progressive weakness of respiratory muscles can impair ventilation and cough effectiveness. Over time, this can lead to restrictive lung disease, recurrent respiratory infections, and decreased pulmonary function.

C. Scoliosis:Weakness of trunk and paraspinal muscles contributes to abnormal spinal curvature. As muscle imbalance progresses, scoliosis commonly develops and can further compromise respiratory function.

D. Insomnia:Sleep disturbances are not a defining or expected manifestation of muscular dystrophy. While fatigue may occur, insomnia is not a characteristic assessment finding related to the disease process itself.

E. Muscle weakness:Progressive, symmetrical muscle weakness is the hallmark feature of muscular dystrophy. It typically begins in proximal muscles and worsens over time, significantly affecting mobility and functional ability.
