Which of the following is a sign that mobilization should be paused?

• A. Worsening agitation, dropping SpO2, tachycardia, hypotension, or increased work of breathing.
• B. Stable signs and comfortable.
• C. Increased appetite.
• D. Red color of monitor.

Answer: (A)

Recognizing signs of intolerance to mobilization in ICU patients is essential to keep them safe during activity. The best cue to pause is when agitation worsens and there are objective signs of instability—dropping SpO2, tachycardia, hypotension, or increased work of breathing. These changes show the patient is unable to tolerate the current activity level and continuing could worsen respiratory or hemodynamic status or lead to adverse events. If signs remain stable and the patient is comfortable, mobilization can proceed with adjustments. Increased appetite isn’t a direct indicator of readiness for mobilization, and a monitor color change isn’t a reliable standalone cue for stopping; focus on the actual vital sign and clinical changes.
