Female patient saw the IV tubing as a snake the nurse consider this reaction as?

Explanation

Core Concept: An illusion is a misperception or misinterpretation of a real, external sensory stimulus (e.g., mistaking an IV tube for a snake in a dimly lit room). This differs from a hallucination (a false perception with no external stimulus) and a delusion (a fixed, false belief).

Clinical Presentation:

• Fear, anxiety, or agitation in response to a misinterpreted object.
• Illusions are common in patients with delirium, poor vision, or in low-light environments.

Diagnosis:

• First-line tool: Comprehensive mental status examination and assessment of the environment.
• Gold standard: Psychiatric evaluation and identifying underlying causes of delirium (e.g., infection, medication toxicity, metabolic derangement).

Management:

• Acute management: Turn on the lights, show the patient the actual object (IV tubing), and provide calm reassurance to reorient them to reality.
• Definitive management: Treat the underlying cause of delirium or sensory impairment (e.g., provide glasses/hearing aids, correct metabolic imbalances, optimize sleep-wake cycles).
