Pathophysiology
Clinical meaning
Cleaning, Disinfection, and Sterilization 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.
