Which statement is a concern for older adult clients undergoing surgery?

• A. Increased immune response to infection
• B. Higher physiologic reserve than younger clients
• C. Decreased hepatic & renal functions that alters clearance of anesthetic agents and opioids
• D. Increased subcutaneous fat

Answer: (C)

As people age, the way their bodies handle drugs changes, especially the organs that clear medications from the body. The most important risk for older adults undergoing surgery is that liver and kidney function often decline, so clearance of anesthetic agents and opioids slows. This means drugs can accumulate in the bloodstream, intensifying effects like sedation and respiratory depression and prolonging recovery from anesthesia. In practice, this requires careful dosing and slower titration, with vigilant monitoring to avoid overdose and complications. The other statements don’t capture this central aging effect. Immune response tends to be reduced, not increased, in older adults, which can raise infection risk rather than create a heightened response. Physiologic reserve is actually diminished with age, not higher, making it harder to tolerate surgical stress. While increased subcutaneous fat can influence drug distribution, the critical perioperative concern is the decreased hepatic and renal clearance that alters how anesthetics and opioids are eliminated.
