In InterRAI LTCF, vision and hearing function are considered through which assessment aspects?

• A. Visual acuity only
• B. Hearing thresholds only
• C. Assessments of sensory impairment and need for aids; affects communication and safety
• D. Environmental lighting only

Answer: (C)

Vision and hearing are evaluated by looking at sensory impairment and the need for aids, because these factors directly influence how residents communicate and stay safe. The assessment goes beyond one measurement; it considers how well a person can function with or without devices like glasses or hearing aids and how those aids mitigate problems in daily interactions and safety.

Focusing only on visual acuity misses how use of corrective lenses or other supports changes communication and safety. Focusing only on hearing thresholds ignores whether a resident uses hearing aids or other amplification. Relying on environmental lighting alone doesn't capture the resident’s actual sensory function or the need for, and effectiveness of, assistive devices. Thus, the comprehensive approach of assessing impairment plus aids best reflects how vision and hearing impact care.
