The nurse is caring for a client with terminal lung cancer who is dying. Which assessment finding is the priority?

A. Restlessness and moaning are clinical indicators of terminal agitation or physical pain, both of which require immediate pharmacological or comfort intervention. Addressing suffering is the primary ethical and clinical goal of end-of-life care to ensure a peaceful transition. The nurse must prioritize these signs of distress over expected physiological changes that occur naturally during the active dying process in terminal cancer. B. Cheyne-Stokes respirations are characterized by a rhythmic pattern of waxing and waning breathing depth followed by periods of apnea. This is a common and expected physiological sign of impending death as the brainstem becomes increasingly hypoxic and loses sensitivity to carbon dioxide. While significant to the family, it is not a sign of distress and does not require active medical intervention in hospice. C. Loss of sphincter control leading to urinary and fecal incontinence is a natural result of generalized muscle relaxation and the shutting down of the nervous system during death. While this requires diligent skin care and hygiene to maintain the client's dignity and prevent breakdown, it is not an acute priority. The nurse should manage this with absorbent pads to keep the client dry and comfortable. D. An irregular heart rhythm often occurs in the final stages of life as the cardiac conduction system fails and the heart becomes increasingly irritable. This expected hemodynamic decline is a part of the multisystem organ failure associated with terminal lung cancer and is not typically treated with antiarrhythmics in palliative care. The focus remains on comfort rather than the restoration of a normal sinus rhythm.
