What sign might indicate that a patient is close to death?

Mottling of the skin is an important sign that may indicate a patient is nearing the end of life. This phenomenon occurs due to changes in circulation as the body begins to shut down. As blood flow diminishes to the extremities, the skin can develop a blotchy, discolored appearance, often with a purplish hue. This mottling reflects a decrease in perfusion and is commonly observed in patients who are actively dying.

Other signs listed, such as increased appetite, bright flush of skin color, and improvement in mobility, do not align with the common signs of approaching death. Increased appetite typically indicates a stable or improving condition, while a bright flush of skin may suggest adequate circulation or increased blood flow, which are not commonly seen as death approaches. Improvement in mobility usually reflects a stabilization or recovery in health, which is contrary to the signs seen in a dying patient. Therefore, mottling of the skin serves as an important clinical indicator in recognizing the dying process.
