Explanation

Organic psychosis is characterized by cognitive impairment resulting from a demonstrable physical cause affecting the brain, such as a head injury, infection, dementia, or substance abuse.
The core features of organic psychosis include significant disturbances in orientation (confusion about time, place, or person), memory (both short-term and long-term), and general intelligence.
According to medical literature, disorientation is considered a hallmark of an 'organic mental state,' which is central to conditions like delirium and dementia.

Option B: In functional psychosis (e.g., schizophrenia, bipolar disorder), the primary disturbance is in thought and perception (delusions, hallucinations), while core cognitive functions like orientation, memory, and baseline intelligence are typically preserved.
Option C: A hallucination is a false sensory perception (e.g., hearing voices). It is a symptom, not a disorder in itself. While hallucinations can occur in organic psychosis, they do not encompass the full triad of disturbed orientation, memory, and intelligence.
Option D: A phobia is an anxiety disorder characterized by an intense, irrational fear of a specific object or situation. It does not cause disturbances in orientation, memory, or intelligence.

Visual 1: Flowchart - A flowchart differentiating organic from functional psychosis. The chart would start with 'Psychotic Symptoms Present?' and branch based on findings like 'Evidence of Brain Disease/Injury?' leading to 'Organic Psychosis' if yes, and 'Functional Psychosis' if no, listing key features for each.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Differential diagnosis of psychosis and cognitive disorders as background academic context rather than a clinical decision trigger.
For a nurse, distinguishing between organic and functional psychosis is critical because the underlying causes and treatments are vastly different. Organic causes may be reversible (e.g., infection, metabolic imbalance) and require immediate medical intervention.
A key nursing responsibility is to perform a thorough mental status examination, specifically assessing for disorientation, memory loss, and changes in intellectual function, as these can be early signs of a serious underlying medical condition.
What if? If a patient with new-onset psychosis also has a fever and headache, the priority shifts dramatically. The nurse must suspect an organic cause like meningitis or encephalitis, report it immediately, and prepare for neurological assessments and potential emergency medical treatment, rather than defaulting to psychiatric care alone.

How to Approach the Question

First, identify the core symptoms presented in the question stem: disturbances of orientation, memory, and intelligence.
Next, analyze each option to determine which condition is defined by this specific triad of cognitive deficits.
Recall the definition of 'organic' in medicine, which points to a physical cause affecting an organ—in this case, the brain.
Contrast this with 'functional' disorders, where no clear organic cause is identified, and with symptoms like 'hallucination' or disorders like 'phobia' which have different defining features.
Conclude that the condition caused by a physical brain issue (Organic Psychosis) is the one that would directly result in widespread cognitive deficits like impaired orientation, memory, and intelligence.
