Which of the following is considered a factor influencing mobility?

• A. Fatigue/stress
• B. Hair color
• C. Blood type
• D. Sun exposure

Answer: (A)

Mobility is influenced by energy levels and psychological state. Fatigue reduces endurance, weakens muscle performance, impairs balance, and can lower motivation to move, all of which limit a person's ability to transfer, walk, or perform daily activities. Stress can heighten muscle tension and affect sleep and concentration, further compromising mobility. Because of this direct impact on physical performance and safety, fatigue and stress are clearly factors influencing mobility.

Hair color, blood type, and sun exposure don’t determine how well a person can move. Hair color and blood type don’t affect muscles, joints, or energy levels in a way that changes mobility, and sun exposure mainly affects skin health and vitamin D status rather than immediate movement ability.
