Which of the following is NOT fundamental assessment information at intake?

The correct choice indicates that documentation regarding referrals and referral outcomes is not considered fundamental assessment information at intake. At the time of intake, the primary focus is on gathering essential information to understand the client's current state and to properly evaluate their needs. This includes a comprehensive evaluation of their substance use history, psychological health, and medical history, as these factors are critical for developing an appropriate treatment plan.

While referrals may be important in the broader context of a client's ongoing treatment and support, they are secondary to the immediate assessment need to establish a baseline understanding of the client's substance use and health issues. Gathering detailed data on psychoactive substance abuse, psychological health, and current medical status provides the necessary context for the clinician to determine the severity of the situation and to formulate an appropriate intervention strategy.

In essence, while referral documentation is valuable in ongoing treatment or in coordinating care with other providers, it does not constitute a primary element of the initial assessment process during intake. Thus, it is not fundamental at that stage.
