A client with end stage chronic obstructive pulmonary disease (COPD) is anxious with labored respirations, increasing dyspnea when attempting to talk, and reports a painful cough. Which intervention should the practical nurse (PN) implement?

A. Restrict family visitation: Family support may help anxiety; restriction is not helpful. B. Administer PRN opioid analgesic: Opioids relieve pain and dyspnea in palliative care, improving comfort. C. Apply a non-rebreather mask: Not appropriate for chronic CO₂ retainers; could worsen hypercapnia. D. Place client in high Fowler's position: Helps breathing but does not address pain; could be done after pain relief.
