Which statement about older adults and anesthesia is true?

Which statement about older adults and anesthesia is true?

• A. Older adults typically have less physiologic reserve
• B. Older adults recover faster than younger patients
• C. Older adults have no risk of anesthetic complications
• D. Older adults require more fluids during recovery

Answer: (A)

Older adults have less physiologic reserve, meaning their bodies have a smaller margin to tolerate the stresses of anesthesia and surgery. Aging brings declines in cardiac output reserve, lung function, and renal and hepatic clearance, along with changes in body composition that alter how drugs are distributed and cleared. These factors make older patients more vulnerable to anesthesia-related hypotension, respiratory depression, delirium, hypothermia, and slower emergence, so the statement about reduced physiologic reserve is true. The other options aren’t accurate: recovery is not generally faster in older adults, they do have real risks of anesthetic complications, and fluid needs during recovery aren’t automatically higher and must be individualized to avoid overload or dehydration.
