Example Question on Delirium Assessment

  • Situational Question:
      - A nurse is conducting an admission assessment for a client suffering from delirium due to an acute urinary tract infection (UTI).
      - Expected Findings:
        - History of gradual memory loss
        - Family members report changes in personality
        - Presence of hallucinations
        - Unchanged levels of consciousness
        - Signs of restlessness

Clinical Decision Making in Confusion Cases

  • Scenario:
      - An older patient presents with acute confusion after taking tranquilizers for a week; vital signs are normal.
  • Nursing Actions:
      - A. Consider age-related physiological changes that may impact drug metabolism and pharmacokinetics.
      - B. Do not adjust medication unless the confusion is directly attributed to an infection.
      - C. Document the timing of confusion episodes and administer medication preemptively if necessary.
      - D. Avoid restricting phone calls as this may exacerbate confusion.

Assessment Tools in Nursing Process

  • Previous Knowledge Required:
      - Level of consciousness (LOC)
      - Orientation
      - General survey skills

  • Assessment Tools:
      - Mini-Mental State Exam (MMSE)
      - Glasgow Coma Scale (GCS)

  • Psychosocial Focused Assessment:
      - Evaluation factors including:
        - Appearance
        - General Attitude
        - Mood and Affect


Potential Reversible Causes of Acute Confusion

  • Scenario:
      - A recently widowed older adult, dehydrated and admitted for IV fluid replacement, presents with acute confusion during the evening shift.
  • Possible Reversible Causes to Consider:
      - Electrolyte imbalance
      - Sensory deprivation
      - Hypoglycemia
      - Effects of medication/drugs

Assessment of Confusion and Agitation

  • Behavioral Observations:
      - A nurse takes a health history from the daughter of a confused and agitated patient, diagnosed with Alzheimer’s disease a year prior. The patient was confused and hallucinating last evening.
