Which statement best describes a frail older adult's presentation of weakness?

• A. Weakness and exhaustion
• B. Weight gain due to reduced activity
• C. Increased stamina
• D. High energy

Answer: (A)

Weakness and exhaustion best describe frail older adults because frailty involves reduced physiologic reserve with decreased muscle strength (sarcopenia) and low energy, leading to easily fatigability and a limited ability to sustain activity. Weight changes in frailty often show unintentional weight loss, not gain, and choices describing increased stamina or high energy contradict the typical diminished endurance and activity seen in frailty.
