For a dependent, sedated, intubated, or cognitively impaired patient, the mouth and the skin are where preventable harm begins. Dental plaque becomes colonised with respiratory pathogens within 48 hours of hospital admission, and micro-aspiration of that biofilm is the dominant mechanism behind non-ventilator hospital-acquired pneumonia — one of the most common and most preventable hospital-acquired infections in Canadian acute care. Moisture trapped against skin from incontinence or unmanaged perspiration softens the stratum corneum, raises surface pH, and turns ordinary pressure and friction into a full-thickness injury. Every hygiene contact is also the longest uninterrupted look a nurse gets at a patient's whole body, which makes it the single richest assessment opportunity in a shift.

On the exam, writers often pair stable-sounding options with unstable data—notice the mismatch before you commit.
