US NCLEX-RN items often test unstable vs stable, delegation, and first action. Connect Pleural Effusion and Chest Tubes to bedside cues you will reassess first: vitals trends, work of breathing, perfusion, mentation, and pain or ischemic equivalents when relevant. NCLEX items often reward recognizing when subtle instability outweighs reassurance, then selecting nursing actions that protect airway, circulation, and neurologic status before routine tasks.
