When assessing patients in the preoperative area, the nurse knows that which patient is at a higher risk for an altered response to anesthesia?

Rationale: The 82-year-old patient undergoing gallbladder removal is at higher risk due to age-related physiological changes. Elderly patients have decreased organ function, altered drug metabolism, and increased sensitivity to anesthesia, leading to potential complications. Option A is less likely to have altered response due to youth. Option B's surgery is not as invasive as gallbladder removal. Option D's smoking history is relevant but not as significant as age-related changes in option C.
