A terminally ill patient develops audible, irregular breath sounds. Which explanation is most appropriate?

• A. The irregular sounds will improve with regular suctioning of secretions.
• B. The issue could be due to an incorrect position.
• C. The irregular breathing will likely correct itself in a short time.
• D. The issue is caused by accumulation of mucus or fluid in the airways.

Answer: (D)

Death rattle occurs when secretions accumulate in the airways as a patient nears the end of life and can no longer clear them effectively. The weakened gag and cough reflex allow mucus and fluid to pool, and air moving past these secretions produces audible, irregular breathing sounds. This is a common, expected part of the dying process and reflects the buildup of secretions rather than a reversible airway issue. While suctioning or repositioning might provide temporary relief or comfort, the underlying cause is the accumulation of mucus or fluid in the airways.
