Final answer:
A nursing assistant should stay calm and provide a quiet environment when a resident is confused.
Step-by-step explanation:
The correct response is B) Stay calm and provide a quiet environment. When a resident is confused, it is important for a nursing assistant to remain calm and create a peaceful atmosphere. This can help reduce anxiety and agitation in the resident. The nursing assistant should also use clear and simple communication, provide reassurance, and assist the resident with any immediate needs. Mentioning the date, location, and explaining care may actually worsen the confusion and agitate the resident, so options A) and D) are incorrect. Leaving the resident alone is also not recommended, as they may require assistance or supervision.
