An HCA is caring for a 78-year-old client who has recently been admitted to the hospital from home for a urinary tract infection. The client's family reports she has a history of memory loss but could function independently at home. Now, the HCA observes the client is extremely disoriented, having vivid hallucinations, and her confusion fluctuates throughout the day, being worse at night. The family states this is a significant change from her usual memory issues. What condition do these new symptoms most likely suggest?

Answer options: ✅ Delirium

• Dementia
• Depression
• Normal aging process

Correct answer: Delirium

Explanation: The sudden onset, fluctuating nature, vivid hallucinations, and acute disorientation in response to a medical condition (UTI) strongly indicate delirium. Dementia has a more gradual onset and typically does not involve sudden, acute fluctuations or vivid hallucinations to this extent.
