Chain of Infection

Chain of Infection supports NCLEX-RN infection prevention and control: you break the chain of infection, apply standard precautions to every patient, add transmission-based layers when indicated, and escalate sepsis or exposure concerns without delay. Canadian stems may reference PHAC-aligned language and metric vitals; US items test the same first action and PPE logic. Boards reward policy-faithful sequencing—soap and water after C. diff care, N95 and negative pressure for airborne pathogens when the stem signals it, and rapid response or provider notification when instability appears. Link isolation precautions in practice, PPE & transmission basics, sepsis early recognition, and Canada RN hub · US RN hub. Why it matters for nursing care: Chain of Infection requires early recognition, careful trend assessment, and rapid prioritization when the patient begins to deteriorate. Clinical decisions should connect the underlying pathophysiology to the bedside picture so the nurse can distinguish a stable finding from a red flag that changes urgency, monitoring frequency, and provider communication. Exam relevance: Examiners use first, priority, and most important language. Eliminate answers that delay cultures in stable patients when the stem...
