**5. Conclusion**

As a predecessor of bioethics and a branch of applied ethics, medical ethics was developed by physicians to regulate their interactions with their patients, colleagues, and society [68]. The patient-physician relationship is a unique interaction that is based on trust, dependency, and need, connecting the two [69]. This relationship is

based on communication, ethical principles, and palliative care (PC); it differs from other clinics [3]. This is a stronger and more complex relationship that involves the PC team the patient, and the patient's family before death and during their grieving after death [3].

Laying down a set of rules that society expects medical physicians to abide by, the Hippocratic oath is a social contract with ethical principles [70]. The principles of medical ethics are taught intensively during the first years of medical faculties, but not adequately addressed after graduation, though they could be more useful during professional life [71].

The inevitability of death is highly likely to exert intense emotional pressure on the PC team, the patient, and the patient's families, including fear, hopelessness, despair, and anxiety. Dealing with this pressure appropriately is a part of good clinical management, but in doing so, ethical principles should not be compromised. Because they are not only a part of successful medical practice but a professional regulatory mechanism.

PC requires teamwork of doctors, nurses, physical therapists, clergy, and other essential health professionals [3]. Training the PC employees as a team both increases team communication and gives positive results in terms of patient safety [72]. Thus, the harm caused by communication to the patients and their families would be minimized.

The deaths witnessed by PC employees also affect their private lives [73]. Therefore, they must learn how to cope with the emotional burden of death and pain. Because they do a very special job, they should be trained on these issues. In this way, PC employees' tremendous emotional burdens would not hinder them from following their ethical principles and logic. Because PC principles should not be broken under the impact of emotions, treatments that are not evidence-based and are not beneficial to the patient should not be applied, and symptom management should not be considered secondary.

It is important to keep in mind that violating one principle of medical ethics may lead to a violation of others. The resources used for an unnecessary treatment for a patient in the PC may have violated the principles of truth-telling, respect for autonomy, nonmaleficence, beneficence, justice benefit, harm, justice, and futility.

Knowing, accepting, and applying ethical principles, even in the most unpleasant situations, provides a peaceful working environment for all employees.
