What is the effect of daily sedation interruption on mobilization readiness?

• A. Increases agitation
• B. Promotes wakefulness and tolerance for mobilization, reduces duration of mechanical ventilation, and improves participation
• C. Prolongs mechanical ventilation
• D. No effect

Answer: (B)

Daily interruption of sedation is used to keep sedation light by allowing a regular wake-up each day. The key idea being tested is how waking the patient affects their readiness to mobilize. When sedation is paused, patients tend to become more alert and able to follow simple commands, which makes them more capable of participating in mobilization efforts and physical therapy. This increased wakefulness also supports spontaneous breathing trials and better tolerance of mobilization activities, helping with weaning from the ventilator. As a result, the overall duration of mechanical ventilation tends to shorten, and the patient can engage more fully in rehabilitation. There can be a temporary rise in agitation in some cases, but the overall trajectory is toward improved mobilization readiness and shorter ventilation. Choices suggesting only increased agitation, prolonged ventilation, or no effect do not reflect the beneficial impact of daily sedation interruption on mobilization readiness.
