Aggressive cancer therapy is planned for Mr.Renaulds,80.His nurse is stressed,wondering if the therapy will actually do more harm than good because of the toxic chemicals used.This nurse is struggling with which of the following principles?

A) Autonomy
B) Justice
C) Beneficence
D) Nonmaleficence

The nurse is struggling with the principle of nonmaleficence, which is the obligation to not cause harm or minimize harm to patients. The concern about the potential harm from the aggressive cancer therapy is a reflection of this principle. Autonomy pertains to the patient's right to make decisions for themselves, justice pertains to fair distribution of resources and services, and beneficence refers to the obligation to do good and promote the patient's well-being. While these principles may also be relevant to Mr. Renaulds' treatment, the nurse's specific concern about potential harm is most closely related to the principle of nonmaleficence.
