Final answer:
Adults with just a few instrumental ADL problems are the least likely to require living in a nursing home, as they can often maintain some independence and manage with less intensive support.
Step-by-step explanation:
The individual who is LEAST likely to live in a nursing home is D) adults with a few instrumental ADL (activities of daily life) problems. People who exhibit minor difficulties with instrumental activities of daily living (IADLs) - which may include tasks such as managing finances, transportation, shopping, or housework - often retain a degree of independence and might not require the full-time care provided by a nursing home. On the other hand, individuals categorized as 'old-old' (often defined as over 85 years), those with Alzheimer's disease, and people with basic activities of daily living (ADLs) impairments, such as bathing, dressing, or eating, typically require more intensive support that can be provided in a nursing home.
