Final answer:
A primary Axis 2 diagnosis requires a detailed client history and physical examination according to DSM criteria, which was not provided. For the impaired social skills in the reference question, the child may be tested for autism spectrum disorder.
Step-by-step explanation:
Based on the information provided, the primary Axis 2 diagnosis for the client cannot be determined without additional context or a detailed history and physical examination. Axis 2 refers to personality disorders and intellectual disabilities in the Diagnostic and Statistical Manual of Mental Disorders (DSM), which was used before the release of the DSM-5. Specific diagnostic criteria laid out in the DSM must be met for a diagnosis of any personality disorder. Therefore, choices a) Histrionic Personality Disorder, b) Narcissistic Personality Disorder, c) Antisocial Personality Disorder, and d) Borderline Personality Disorder cannot be evaluated without more information.
In the case of the other question provided for reference regarding a child with impaired social skills, they might be tested for autism spectrum disorder, which commonly presents difficulties with social interactions such as reading social cues and making eye contact.
