Final answer:
The most appropriate intervention by the nurse would be to notify the anesthesia department and the surgeon of the client's refusal.
Step-by-step explanation:
The most appropriate intervention by the nurse in this situation would be to notify the anesthesia department and the surgeon of the client's refusal (Option C).
When a client refuses to remove dentures prior to surgery, it is important to notify the anesthesia department and the surgeon so they can make an informed decision regarding the client's safety during the procedure.
Explaining the risks of keeping the dentures in (Option A), asking about second thoughts (Option B), or suggesting removing the dentures in the operating room receiving area (Option D) may not address the potential complications that could arise from the client keeping the dentures in during surgery.
