Final answer:
A common sign of approaching death is decreased body functions, which can include changes such as decreased body temperature, decreased intestinal peristalsis, and emotional reactions to loss. This decline is part of a natural physiological process as the body prepares for the end of life, leading to a crisis and potential death.
Step-by-step explanation:
Common Sign of Approaching Death
A common sign of approaching death is decreased body functions. This is because, as the body prepares for the end of life, physiological changes begin to occur. For example, a decrease in body temperature, a decline in the pH level of the blood due to increased acidity, and increased carbon dioxide as the body becomes less efficient at removing it. Other signs include decreased intestinal peristalsis and a reduction in aldosterone secretion which affects fluid and electrolyte balance.
Additional signs can include individuals becoming more lethargic as a way to conserve energy and emotional reactions of loss to the impending death. It is important to note that symptoms of decline like weight loss, increased heart rate, or difficulty sleeping, as seen in patient B, may suggest severe illness, but are not necessarily indicative of immediate death. However, a significant decline in organ function and an increase in symptoms such as weakness and an inability to face minor stress can lead to a crisis and death.
The emotional stages of dying, as described by Elisabeth Kübler-Ross, also provide insight into the psychological process associated with approaching death, which includes denial, anger, bargaining, depression, and, eventually, acceptance.
