The nurse is teaching nursing students about the risk factors for developing delirium in older adults. Which student statement indicates understanding of the risk factors of delirium?

"Age-related cognitive changes may lead to alterations in mental status."

Lack of rigorous exercise may lead to alterations in mental status."

"Decreased social interaction may lead to profound isolation and psychosis."

"Taking multiple medications may lead to adverse interactions or toxicity."

Answer and Explanation

The Correct Answer is D

A. "Age-related cognitive changes may lead to alterations in mental status." Age-related cognitive changes, such as mild cognitive impairment, can increase the risk of delirium, but the statement is too general. Delirium is typically acute and caused by specific factors like medication, infection, or metabolic imbalances, not just normal age-related changes . Therefore, this choice is incorrect.

B. "Lack of rigorous exercise may lead to alterations in mental status." While lack of exercise can impact overall health and well-being, it is not a direct risk factor for delirium. Delirium is more closely associated with acute medical conditions, medication interactions, or environmental factors . Therefore, this choice is incorrect.

C. "Decreased social interaction may lead to profound isolation and psychosis." Decreased social interaction can lead to isolation and mental health issues like depression, but it is not a direct cause of delirium. Delirium typically results from acute physiological changes rather than social factors . Therefore, this choice is incorrect.

D. "Taking multiple medications may lead to adverse interactions or toxicity." Polypharmacy, or taking multiple medications, is a significant risk factor for delirium in older adults due to the potential for adverse drug interactions and toxicity. This can lead to acute changes in mental status characteristic of delirium . This choice is correct.
