Answer to Question 1

Correct Answer: 1,2,3,4
Rationale 1: Homeostatic mechanisms have the four main characteristics identified, self-regulation among them.
Rationale 2: Homeostatic mechanisms have the four main characteristics identified, a compensatory nature among them.
Rationale 3: Homeostatic mechanisms have the four main characteristics identified, negative feedback systems among them.
Rationale 4: Homeostatic mechanisms have the four main characteristics identified, a need for more than one feedback mechanisms among them.
Rationale 5: Homeostatic mechanisms have the four main characteristics identified. The closed-system concept is not among the characteristics.

Answer to Question 2

Correct Answer: 2
Rationale 1: Primary prevention is true health promotion and provides specific interventions against disease.
Rationale 2: Secondary prevention emphasizes early detection of disease, prompt intervention, and health maintenance for individuals experiencing health problems. Because the pneumonia is a current health problem, interventions focused on that would be considered secondary prevention.
Rationale 3: All cares related to rehabilitation following the brain injury would be tertiary prevention. Tertiary prevention focuses on rehabilitating individuals to an optimum level of functioning.
Rationale 4: Acute care is a part of health care, but not one of the levels of prevention.
