The two basic categories of diagnosis used for behavioral crises or psychiatric emergencies are:

• A. organic brain syndrome and altered mental status
• B. functional and nonfunctional
• C. physical and psychological
• D. All of these answers are correct.

Answer: (C)

Two broad categories clinicians use when evaluating behavioral crises are physical (medical/biological) causes and psychological (psychiatric/mental health) causes. This division helps responders quickly address what might be a life-threatening medical issue—such as infection, head injury, hypoglycemia, intoxication, or metabolic problems—while also considering psychiatric or emotional factors that influence behavior, like mood disorders, psychosis, or acute stress reactions. By separating physical from psychological contributors, you can triage effectively: treat any medical emergencies first, then assess and address psychiatric needs or referral.

The other options aren’t the standard two-category framework. Organic brain syndrome and altered mental status describe medical conditions affecting cognition rather than a general two-domain approach; functional and nonfunctional isn’t a typical dichotomy used in this context; and saying all choices are correct would imply those categories are all equivalent frameworks, which they aren’t.
