In the near Future, the Largest Segment of the Population

In the near future, the largest segment of the population will be those over age 65 years. To advocate for this vulnerable population, a nurse was a strong supporter for the Medicare Modernization Act (Medicare Part D) , which:

A) provided vision care benefits to elderly persons who were diagnosed as legally blind.
B) removed limits to access to mental health/substance abuse services which are the most commonly used service in this population.
C) provided coverage for medications for Medicare enrollees that constituted a huge expense for the elderly.
D) expanded the practice opportunities for advanced practice registered nurses (APRN) who provide the majority of care for this population.
