Question

question 94
an 80 - year - old patient becomes apathetic, with decreased alertness and a slowing of speech several days after hip replacement surgery alternating with long periods of lucidity. what is the most likely cause of these symptoms?
○ anesthesia effects
○ delirium
○ pain medications
○ stroke

Explanation:

Delirium is an acute confusional state that can occur after surgery (such as hip replacement) in elderly patients. It is characterized by fluctuating mental status (alternating with periods of lucidity), decreased alertness, and changes in speech (like slowing). Anesthesia effects usually do not last several days. Pain medications might cause some sedation but not the fluctuating nature described. A stroke would likely have more consistent and severe neurological deficits rather than the described pattern.

Answer:

Delirium
