Sedation and Analgesia (Critical Care) integrates university-level pathophysiology with ICU bedside RN practice: rapid assessment of perfusion and oxygenation, interpretation of labs and monitoring, safe medication titration, complication prevention, and timely escalation aligned with NCLEX-RN and acute-care expectations. US NCLEX-RN items test ABC + perfusion first, shock type differentiation, ventilator safety, vasopressor/medication safety, and early escalation under acute deterioration. Pathway context (RN, United States). Continue with related lessons from the pathway lesson hub. Learning objectives - Apply pathophysiology, assessment cues, labs/diagnostics, nursing priorities, escalation criteria, medication safety, monitoring, complications, clinical reasoning cases, and NCLEX traps for this critical care topic. - Differentiate shock types, respiratory failure patterns, and lethal electrolyte emergencies before selecting interventions. - Communicate objective trends that trigger rapid response, code team, or provider escalation.
