Which of the following is a force for future change in healthcare service delivery?

Rationale:

A. Car model: The "Car model" is not a recognized model of Health Maintenance Organization (HMO). It seems to be a distractor in this context.

B. Network model: In the network model, the HMO contracts with multiple independent medical groups or practices to provide healthcare services to its members.

C. Group model: In the group model, the HMO contracts with a single medical group, which employs physicians and provides healthcare services to HMO members.

D. Staff model: In the staff model, the HMO directly employs physicians and other healthcare providers who deliver services to its members.

A. A nonfederal short-stay hospital whose services are available to the general public: Community hospitals are defined as nonfederal short-stay hospitals that provide a range of services to the general public and are accessible to all members of the community.

B. Nongovernment and privately owned: While many community hospitals may be privately owned, this option does not encompass the full definition as it excludes government-owned hospitals that serve the community.

C. Government ownership (federal, state, or local): Community hospitals can be government- owned, but this answer does not capture the full scope of what defines a community hospital.

D. Often located in large urban areas: Community hospitals can be found in both urban and rural areas, so this answer is not sufficiently inclusive.
