Which of the following are signs of impending death?

The correct signs of impending death include decreased responsiveness, weakened pulse, and irregular breathing. As a person approaches death, it is common for their body to begin shutting down. Decreased responsiveness indicates that the individual may be less aware of their surroundings and less able to engage in conversation or respond to stimuli.

A weakened pulse reflects a decline in circulation and overall bodily functions, meaning the heart is struggling to pump blood effectively. Irregular breathing patterns, such as periods of rapid breathing followed by periods of no breathing, are also indicative of the body losing its ability to maintain normal respiratory function as it nears the end of life. These physical signs provide clear indications that vital functions are deteriorating, which is consistent with the natural process of dying.

In contrast, the other choices highlight behaviors and states that are contrary to this process, such as increased energy or social interactions, which are not typical as a person nears death.
