Final answer:
The ethical principle that involves keeping promises and commitment to patient care despite challenges is known as fidelity.
Option B.
Step-by-step explanation:
The question refers to the ethical principle that emphasizes the importance of keeping promises and the obligation not to abandon patients, even when their care is controversial or complex.
This principle is known as fidelity. Fidelity is one of several principles that guide ethical decisions in healthcare, which include autonomy, beneficence, nonmaleficence, and justice.
The principle of autonomy asserts that patients have the right to make decisions about their care.
The principle of beneficence emphasizes actions that are beneficial for others. The principle of nonmaleficence requires avoiding harm, and the principle of justice promotes fair treatment for all.
