Statutory law consists of laws written and enacted by the U.S. Congress, the state legislatures, and other governmental entities such as cities, counties, and townships.

A) The client's spouse: This choice suggests that the client's spouse has the authority to give permission for a DNR order. In most cases, it is the competent client themselves who has the authority to make decisions about their own medical treatment, including DNR orders. Spouses may have a say and their input is considered, but the ultimate decision typically lies with the competent client.

B) The client's only child: This choice suggests that the client's only child can give permission for a DNR order. Similar to the explanation for choice A, the decision-making authority for a DNR order generally rests with the competent client, not their child. However, a client may choose to discuss their medical decisions with their child and take their wishes into consideration.

C) The client: This choice correctly identifies that the competent client themselves is the one who typically has the legal and ethical authority to make decisions about their medical treatment, including DNR orders. This is based on principles of autonomy and respect for the individual's wishes.

D) Any close blood-related relative: This choice suggests that any close blood-related relative has the authority to give permission for a DNR order. Similar to choices A and B, the decision-making authority is typically with the competent client. While family members' input is valuable and should be considered, they do not have the ultimate decision-making power for the client's medical treatment.

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.
