Answer to Question 1
Ans: C
In the past, health care focused on the treatment of illnesses rather than prevention through health promotion, because preventive strategies were not covered by health insurance. Health awareness and the desire to be involved in one's own health care have strongly influenced the delivery of health care services in our society.
Answer to Question 2
Ans: B
Preferred provider organizations (PPOs) allow a third-party payer (agencies that pay health care providers for services provided to individuals, such as a health insurance company) to contract with a group of health care providers to provide services at a lower fee in return for prompt payment and a guaranteed volume of clients and services. Although clients are encouraged to use specific providers, they may also seek care outside the panel without referral by paying additional out-of-pocket expenses.
