A nurse notices that a client who was just informed they need chemotherapy immediately begins explaining to family members the detailed biology of cancer cell growth and treatment mechanisms. What coping mechanism is this?

INTELLECTUALISATION: Converting a threatening emotional situation into an intellectual exercise to manage anxiety; PRESENTATION: The individual becomes an 'expert' on their diagnosis; researches every detail; discusses statistics and biology; may appear calm and in control; DISTINGUISHED FROM: Healthy information-seeking (intellectualisation uses information as a SHIELD against emotion, not alongside emotional processing); THERAPEUTIC APPROACH: Allow the intellectual engagement — it provides a sense of control; do NOT force emotional processing prematurely; OPEN THE EMOTIONAL DOOR gently: 'You clearly understand this well. How are you feeling about all of this?'; WATCH FOR: Intellectualisation preventing necessary decisions or communication with family; extreme cases where no emotional processing occurs may indicate dissociation; ADAPTIVE vs MALADAPTIVE: Short-term, intellectualisation is often adaptive — it allows the person to gather information needed for decision-making while limiting overwhelming emotion; long-term, avoiding emotional processing entirely can prolong adjustment.
