Final answer:
Medicaid is designed to provide healthcare assistance to poverty-stricken individuals and families who cannot afford medical care. It supports low-income adults, children, and others who meet specific poverty criteria, not only those with kidney failure, people aged 65 and older, or the unemployed.
Step-by-step explanation:
Medicaid is a government program intended to assist individuals and families who are in need of healthcare but may not have the financial means to pay for it themselves. This program primarily benefits those who are living in poverty, which makes option 4) poverty-stricken people the correct answer for whom Medicaid is intended. Medicaid helps a wide range of people including low-income adults, children, pregnant women, elderly adults, and people with disabilities. It is not specifically targeted to individuals with kidney failure, people aged 65 and older (as they are often covered by Medicare), or unemployment status alone, although these groups may also qualify if they meet the poverty guidelines.
