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 A
Explanation
A Do Not Resuscitate (DNR) order is indeed legally separate from advance directives. While both deal with medical interventions, they are distinct concepts:
Advance directives are legal documents that allow individuals to specify their medical treatment preferences in case they become unable to communicate or make decisions. These can include living wills, durable power of attorney for healthcare, and healthcare proxies. Advance directives provide a broader set of instructions regarding medical care and decision-making.
DNR orders, on the other hand, specifically address the issue of cardiopulmonary resuscitation (CPR). A DNR order instructs healthcare providers not to attempt CPR if a person's heart stops beating or they stop breathing. DNR orders are often a part of a person's broader advance directives, but they focus specifically on resuscitation efforts.

Explanation
Egoism: Egoism is an ethical theory that emphasizes self-interest as the motivation for human behavior. It suggests that individuals act in their own self-interest and seek to maximize their own happiness or well-being.
Utilitarianism: Utilitarianism is an ethical theory that states the best action is the one that maximizes overall happiness or pleasure. It focuses on the consequences of actions and aims to achieve the greatest good for the greatest number of people.
Deontological: Deontological ethics, also known as duty-based ethics, focuses on the inherent nature of an action, rather than its consequences. It suggests that some actions are inherently right or wrong, regardless of the context or outcomes.
Jurisdictional: Jurisdictional refers to the legal authority or power of a court or other governmental entity to make decisions and judgments within a specific geographical area or in a particular legal domain. It does not directly relate to ethical decision-making principles.
