Which of the following symptoms should a nurse aide monitor for in a dying patient?

Monitoring changes in breathing patterns is crucial in a dying patient because it often indicates the progression of the dying process. As a patient approaches the end of life, their breathing may become irregular, shallow, or exhibit periods of apnea (pauses in breathing). This is a normal physical change and can provide valuable information to the healthcare team regarding the patient's condition and comfort level.

In contrast, the other symptoms listed, such as improved appetite, increased energy levels, and rapid weight gain, are generally not expected in a dying patient. Advance deterioration usually leads to decreased appetite and energy, indicating the body is shutting down rather than revitalizing. Monitoring breathing patterns thus provides insight into the patient's state and can directly influence care decisions to enhance comfort and ensure a peaceful transition.
