Final answer:
Nursing assistants can best support elderly residents with memory loss by creating a safe and familiar environment, encouraging activities and social connectedness to stimulate memory.
Step-by-step explanation:
Nursing assistants can help elderly residents with memory loss by B) creating a safe and familiar environment. Memory loss, such as that caused by Alzheimer's disease, often involves the presence of brain plaques and significant cognitive decline, where a person can forget essential life skills. Nursing assistants are not qualified to provide medications, so offering memory-enhancing medications (A) is outside their scope of practice. They should also avoid encouraging patients to forget about their memory loss (C) as it is essential to address the issue compassionately. Likewise, they are not specialized clinicians to administer daily memory tests and quizzes (D), and continuous testing can be stressful for patients. Nonetheless, nursing assistants can support cognitive function through psychosocial development, encouraging activities and social connectedness that have been shown to help stimulate memory and overall well-being.
