7.3 Dementia, Confusion, Delirium, and Behavior Support

Key Takeaways

  • Dementia is a long-term change in memory and thinking, while sudden confusion may signal an urgent medical change.
  • The nurse aide should use simple words, calm tone, familiar routines, and redirection instead of arguing.
  • Behavior is communication; pain, hunger, fear, noise, infection, fatigue, and overstimulation can all affect behavior.
  • Sudden confusion, new aggression, hallucinations, falls, fever, or major behavior change must be reported immediately.

Supporting Residents With Confusion

The knowledge exam may describe a resident who repeats questions, searches for a deceased family member, becomes agitated during bathing, wanders toward an exit, or suddenly does not recognize staff. The nurse aide's response should protect safety without humiliating the resident. Confusion does not remove the resident's right to dignity.

Dementia is a general term for long-term decline in memory, thinking, communication, and ability to perform usual activities. Alzheimer's disease is one cause of dementia, but the aide does not diagnose the cause. Delirium is sudden confusion or a sudden change in attention and alertness. Delirium can be related to infection, dehydration, medication effects, pain, low oxygen, or other urgent problems. A resident who is suddenly much more confused than usual should be reported promptly.

A key exam principle is that behavior is often communication. A resident who hits during a bath may be cold, embarrassed, in pain, frightened by the sound of running water, or unable to understand what is happening. A resident who paces may need the bathroom, exercise, reassurance, or a quieter space. The aide should look for basic, reportable facts: what happened, when it started, what was happening right before, what helped, and whether the resident was at risk of harm.

Communication should be simple and adult. Use short sentences, one direction at a time, and a calm facial expression. Approach from the front, identify yourself, and avoid sudden touch. If a resident is upset, lower noise, reduce the number of people speaking, and allow space if safe. Redirection works better than arguing. For example, if a resident says they need to pick up children from school, the aide might say, "You are worried about them. Let's sit here and look at your family photos while I tell the nurse you are upset."

Safety is always part of psychosocial care. Report sudden confusion, new weakness, fever, new pain, a fall, suspected infection, hallucinations, threats, or behavior that may harm the resident or others. Do not physically restrain a resident unless following emergency facility policy and directions from licensed staff. Do not use labels such as difficult or crazy in documentation or report. Describe what you saw and heard. The exam usually rewards factual observation, calm support, resident dignity, and timely reporting.
