Why are antianxiety medications used cautiously in older adults?
Correct answer
Poor circulation affects distribution but isn't primary. Liver metabolism slows, not hastens. Acid production impacts some drugs, not anxiolytics. Reduced elimination increases buildup, risking side effects.
Rationale
The correct answer is D: There is reduced elimination, leading to a buildup in the circulation. In older adults, the kidneys tend to function less efficiently, resulting in reduced elimination of medications from the body. This decreased clearance can lead to a buildup of antianxiety medications in the bloodstream, potentially causing adverse effects or toxicity. This is why antianxiety medications should be used cautiously in older adults to prevent these risks.
Choices A, B, and C are incorrect because poor circulation, faster liver metabolism, and decreased acid production are not the primary reasons why antianxiety medications are used cautiously in older adults. These factors may influence drug absorption or metabolism, but the key concern with antianxiety medications in older adults is the reduced elimination leading to potential drug accumulation and its associated risks.
