Which is an element of negative feedback?
Maintains stability.
Encourages change.
Produces change.
Improves the system.
The Correct Answer is A
Maintains stability: Negative feedback in a system is a regulatory mechanism that helps maintain stability and homeostasis. When a deviation occurs from a set point, negative feedback mechanisms work to bring the system back to its normal state, thus maintaining stability.
Encourages change: Negative feedback doesn't encourage change; rather, it resists change and maintains the status quo.
Produces change: Positive feedback mechanisms produce change by amplifying the initial deviation from the normal state, while negative feedback works to counteract these deviations and restore stability.
Improves the system: While negative feedback maintains stability, whether it improves the system or not depends on the context. It can be beneficial for maintaining internal balance, but in some cases, it might not necessarily lead to system improvement, especially if the system is functioning optimally already.

Correct Answer is D
Explanation
Assault: Assault involves the threat of harmful or offensive contact. It doesn't apply here because there is no immediate threat of physical harm in this situation.
Battery: Battery involves actual physical contact without the person's consent. This situation doesn't involve physical contact.
Invasion of privacy: Invasion of privacy refers to intruding upon a person's private affairs. This situation doesn't involve an intrusion of privacy.
False Imprisonment: False imprisonment occurs when a person is unlawfully restrained from moving about freely. In the context described, if a client is not allowed to leave the hospital until the bill is paid, it can be considered false imprisonment as the person is being unlawfully restrained from leaving. Patients generally have the right to refuse treatment or leave a hospital, except under specific circumstances such as imminent danger to themselves or others. Restraining a patient due to unpaid bills without medical necessity constitutes false imprisonment.
Correct Answer is C
Explanation
An individual who is responsible for his or her health care: While client responsibility is a concept in healthcare, it is not the primary focus of Johnson's Behavioral System Model. The model primarily focuses on the client as a dynamic system.
A behavioral system that is an integrated whole: This statement is partly correct; however, it doesn't fully capture the essence of Johnson's model. Johnson does focus on behavioral systems, but the model is more comprehensive, considering the client as a dynamic entity with inputs, processes, and outputs.
A dynamic entity with both input and output: This accurately reflects the essence of Johnson's Behavioral System Model. In this model, the client is seen as a dynamic system that processes inputs (stimuli from the internal and external environment) and produces outputs (responses or behaviors). The interactions between these inputs and outputs determine the client's adaptation and overall health.
An individual who must adapt to illness: While adaptation is a central concept in Johnson's model, it doesn't solely focus on illness adaptation. It encompasses a broader view of the individual's behavioral responses to various stimuli and stressors in both health and illness contexts.
