判断题

Some families might perceive the request for donation to imply that the principal concern of the medical team is with the patient's organs rather than with the patient. It may be appropriate to delegate these discussions to representatives from an organ procurement organization or a program representative from the health care organization itself.

A. 对
B. 错

判断题

Over concern regarding caregiver conflict of interest can paralyze efforts toward organ donation. It should be recognized that clinicians have no duty to patients who want to donate their organs. This duty is to make donation occur if feasible and ethically appropriate.

A. 对
B. 错

判断题

Many caregivers and organizations are so concerned about perceived conflict of interest that they fail to address their duty to fulfill patients' wishes.

A. 对
B. 错

判断题

A. 对
B. 错

判断题

A. 对
B. 错

判断题

Neuropathological studies have showed that damage to the brainstem was critical for brain death. These findings initiated the concept of "brainstem death" and led UK physicians to define brain death as complete, irreversible loss of brainstem function: "if the brainstem is dead, the brain is dead, and if the brain is dead, the person is dead".

A. 对
B. 错

判断题

The brain-centered definition of death has a whole brain, brainstem and neocortical formulation. At present, only the two former concepts have an accepted medical basis. According to the consciousness- or personhood-centered neocortical definition of death, patients in a vegetative state are considered alive.

A. 对
B. 错

判断题

Death is regarded as the continuous event (linguistically it can be understood only as an event) that separates the continuous process of dying from the subsequent disintegration.

A. 对
B. 错

判断题

Brain death signifies death not because it is invariably imminently followed by asystole, but because it is accompanied by irreversible loss of critical cerebral functions. The concept of brain death as irreversible loss of the capacity of the organism to function as a whole that results from the permanent loss of its critical system is invalidated by the time lag between the diagnosis of brain death and cardiac arrest.

A. 对
B. 错

判断题

The whole brain formulation requires the bedside demonstration of irreversible cessation of all clinical functions of the brain, and is the most widely accepted.

A. 对
B. 错
