A nurse is assessing an adolescent who has beta thalassemia. The parents ask the nurse about other manifestations to watch for in their child. The nurse recognizes that children who have beta thalassemia have the potential for which of the following psychosocial diagnoses?

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 skills: Thyroid hormone deficiency can impair muscle tone and coordination, leading to delayed gross and fine motor development. Motor delays are common but may improve with treatment initiation. They are not the most severe long-term consequence if the condition remains untreated.

B. Delayed social interactions: Social development may be affected secondary to overall developmental delay, but it is not the primary or most critical impact of untreated congenital hypothyroidism. Social deficits often reflect underlying cognitive impairment rather than isolated thyroid effects. Early hormone replacement can mitigate these concerns.

C. Delayed language development: Language delay is frequently observed due to impaired neurologic maturation and slowed cognitive processing. While significant, language skills are influenced by broader cognitive function. Addressing thyroid deficiency early helps prevent long-term speech and language deficits.

D. Delayed cognitive abilities: Thyroid hormone is essential for brain development, particularly in early childhood when neuronal growth and myelination are most active. Untreated congenital hypothyroidism can result in permanent intellectual disability. Cognitive impairment represents the most serious and irreversible developmental consequence.
