Which interprofessional strategy is used to reduce delirium risk and symptoms?

• A. Prolonged bed rest
• B. Increased sedation
• C. Early mobility
• D. Isolation precautions

Answer: (C)

Delirium in the ICU is strongly linked to immobility, sedation, sleep disruption, and sensory deprivation. An interprofessional approach that directly counters these factors is early mobility—getting the patient moving as soon as it is medically safe, with a coordinated team of nurses, physical and occupational therapists, and physicians guiding the plan. Progression is tailored and safe: start with passive range of motion, advance to sitting at the edge of the bed, then to transfer to a chair, standing, and eventually walking as tolerated. This strategy helps maintain muscle strength, respiratory function, and daily activity tolerance, which reduces the need for deep or prolonged sedation. By promoting wakefulness and engagement, early mobility supports normal sleep–wake cycles and orientation, which are protective against delirium. When part of the ICU care bundle that includes daily sedation minimization and structured activity, early mobility lowers the risk and shortens the duration of delirium. In contrast, prolonged bed rest keeps patients deconditioned and less able to participate in activity, increased sedation raises the likelihood of delirium by suppressing arousal, and isolation precautions don’t inherently reduce delirium and can contribute to sensory deprivation if not combined with orientation and stimulation. Early mobility directly targets the factors most closely tied to delirium risk.
