Which statement about the definition of death is noted in the material?

• A. It has changed in recent years
• B. It has remained fixed since the 19th century
• C. It is defined solely by cardiopulmonary criteria
• D. It is determined only by physician judgment

Answer: (A)

Definitions of death have evolved with medical advances. Historically, death was declared when the heart and lungs ceased functioning, but advances in critical care and neuroscience introduced brain-based criteria for death, with many systems recognizing brain death as death even if the heart is mechanically kept working. This shift shows that the definition has changed in recent years, making that statement the best choice. The other ideas don’t fit as well: death definitions have not remained fixed since the 19th century, death is not defined solely by cardiopulmonary criteria, and determining death relies on explicit criteria and guidelines rather than a clinician’s judgment alone.
