A nurse is assisting in the care of a client in the intensive care unit (ICU). Drag words from the choices below to fill in each blank in the following sentence. The nurse should identify that the client's dropdownand dropdowncan indicate the development of delirium.

Rationale for correct choices: • Change in orientation: The client was initially alert and oriented to person, place, and time, but then became oriented to person and place only and gave an incorrect year (“It’s 1975”). Acute changes in orientation are a hallmark feature of delirium, reflecting fluctuating cognitive function, inattention, and disorganized thinking. • Hallucinations: The client reports seeing spiders crawling on the bed and expresses distress over these perceptions, which are not real. Hallucinations are a common manifestation of delirium, especially in older adults experiencing acute illness, infection, or post-operative complications. Rationale for incorrect choices: • Illusions: Illusions involve misperceiving real stimuli (e.g., seeing a shadow as a person), whereas the client is reporting things that are not present, which are true hallucinations. While illusions can occur in delirium, the client’s experiences reflect hallucinations, making illusions less accurate for identifying delirium here. • Past medical history: The client’s history of hypertension, congestive heart failure, and Parkinson’s disease may increase vulnerability to delirium but does not directly indicate that delirium is occurring. Acute manifestations, such as changes in orientation and hallucinations, are more reliable indicators than past medical history.
