Adult-Gerontology CNS Practice Exam 2026 – Complete Prep Guide

In geriatric practice, while all aspects listed can influence an older adult's function, intelligence is generally considered the least critical. This is because functional ability in older adults is more directly impacted by a range of other factors, such as physical health, motivation, and the surrounding environment.

The environment plays a significant role, as it can either facilitate or hinder an older adult's ability to perform daily tasks. A supportive, accessible environment can improve independence and overall functionality. Similarly, overall physical health is crucial, as conditions such as chronic illness or mobility issues can directly affect an individual's ability to engage in daily activities.

Patient motivation is also vital; an older adult's desire to maintain independence and participate in care decisions greatly influences their functional outcomes. While intelligence can impact problem-solving and understanding of health-related information, it does not have as immediate or significant an effect on physical capabilities and daily functioning as the other factors mentioned. Therefore, in the context of geriatric practice, intelligence is less critical compared to the more pressing concerns of health, environment, and motivation.
