Which ethical principle includes the professional's faithfulness or loyalty to agreements and responsibilities accepted as part of the practice of the profession?

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.

Collect the data and consider the alternatives: This step involves gathering all relevant information about the situation and identifying possible courses of action. It's essential to have a clear understanding of the problem and the available options before making a decision. However, this is not typically the very first step in the ethical decision-making process, as collecting data often precedes considering alternatives.

Collect, analyze, and interpret the data: This is the correct first step in the ethical decision-making process. It emphasizes the importance of systematically gathering information, analyzing it to identify ethical concerns, and interpreting the data to understand the ethical implications.

Collect data and consider the consequences of the actions: While considering the consequences is a crucial part of ethical decision-making, it usually comes after collecting and analyzing the data. It's important to evaluate the potential outcomes of each alternative once you have a clear grasp of the ethical issues involved.

Collect the data and make a decision: Making a decision is the final step in the ethical decision-making process. While data collection is an essential part of the process, making a decision should follow a careful analysis and consideration of the ethical implications. Jumping straight to a decision without thorough analysis can lead to unethical choices.
