An older woman who was recently diagnosed with end stage metastatic breast cancer is admitted because she is experiencing shortness of breath and confusion. The client refuses to eat and continuously asks to go home. Arterial blood gas results indicate hypoxia. Which intervention is most important for the nurse to implement?

A. Clarify end of life desires: While understanding a client’s goals is vital, this may not address her immediate needs. The client is already showing signs of distress and hypoxia, so initiating comfort measures promptly is more urgent than discussing future preferences. B. Offer sips of favorite beverages: Offering fluids may help with oral comfort but does not address the client’s respiratory distress or overall suffering. It is a low-priority intervention in the setting of acute hypoxia and confusion related to terminal illness. C. Initiate comfort measures: Comfort measures are the priority for a terminally ill client with hypoxia and confusion who is refusing food and expressing a wish to go home. This aligns care with the client's likely stage in the dying process and ensures symptom relief over aggressive interventions. D. Prepare for emergent oral intubation: Intubation is invasive and likely inconsistent with palliative goals in end-stage cancer. Without clear patient consent or indication that life-prolonging measures are desired, focusing on comfort is more appropriate and ethical.
