Final answer:
The most suitable outcome for a child with ASD and a nursing diagnosis of disturbed personal identity is establishing a means of communicating personal needs by discharge, as it directly facilitates self-expression and identity formation.
Step-by-step explanation:
The best outcome to address a nursing diagnosis of disturbed personal identity in a child diagnosed with autism spectrum disorder (ASD) is B. The client will establish a means of communicating personal needs by discharge. This outcome is crucial as children with ASD may have difficulty with verbal and nonverbal communication, often a characteristic symptom of the disorder. By facilitating a means of communication, the child can express their individual needs and preferences, contributing to the development of a sense of self and identity. Options A and C focus on naming body parts and initiating social interactions, which also contribute to a sense of self but may not directly address personal needs communication. Option D, regarding safety, is essential but does not directly relate to the concept of personal identity.
