Final answer:
Loss of hearing is not one of the geriatric giants. The recognized geriatric giants mainly include issues like immobility, impaired memory, instability, and incontinence, impacting elderly independence and quality of life.
Step-by-step explanation:
The term geriatric giants refers to common large-impact health challenges faced by the elderly. These giants typically include immobility, impaired intellect/memory (including conditions like dementia and Alzheimer's disease), instability (referring to balance and fall risks), and incontinence. Among the listed options, the one that is NOT one of the geriatric giants is loss of hearing. While sensory decline, including hearing loss, is indeed a common issue in old age, it is not typically categorized under the term 'geriatric giants,' which focuses more on functional and cognitive impairments that have a major impact on the independence and quality of life of older adults.
