Final answer:
The accessibility principle of Medicare means universal access, indicating that the program is designed to be available to all eligible persons, which is option B) Universal access.
Step-by-step explanation:
The accessibility principle of Medicare refers to the principal objective of providing universal access to healthcare for eligible individuals, primarily focusing on those over sixty-five years old, certain younger people with disabilities, and individuals with End-Stage Renal Disease (permanent kidney failure requiring dialysis or a transplant). It is worth noting that while Medicare offers this broad access, the Patient Protection and Affordable Care Act, commonly known as Obamacare, aims to provide all Americans with access to affordable health insurance, further detecting the theme of universality in U.S. healthcare policy.
The correct answer to the question about the accessibility principle of Medicare is B) Universal access, which indicates that the program is designed to be available to all eligible persons, without discrimination or limitations based on income, social status, or geography.
