Step-by-step explanation:
The primary nursing goal for a hospitalized toddler is to invoke a sense of security and trust in the hospital environment, primarily by encouraging parents to room in. This practice supports the child's emotional and psychological needs and aligns with Erikson's stages of psychosocial development, where toddlers need to resolve the issue of autonomy versus shame and doubt. Having parents close by provides a secure base for toddlers, thereby fostering a secure attachment, which is crucial for their healthy emotional development.
