Which of the following diagnoses is most likely to be given as the result of mental status examinations?

A mental status examination is a structured way of observing and describing a client’s current state of mind, under the domains of appearance, attitude, behavior, mood and affect, speech, thought processes, thought content, perception, cognition, insight, and judgment. It is NOT a psychiatric evaluation aimed at diagnosing disorders. Many disorders or conditions cause delirium, such as alcohol/drug abuse or withdrawal and infections. Delirium involves a quick change between mental states (e.g., from lethargy to agitation and back to lethargy). Symptoms that can be detected by a mental status examination include changes in alertness (usually more alert in the morning, less alert at night), awareness, orientation to time or place, memory, recall, and mood (personality changes).
