Prompt
You are the night paediatric registrar. A 3-year-old on the ward has a rising multi-parameter PEWS, incomplete blood pressure documentation, increasing oxygen need, and a parent who says the child is getting worse. The examiner releases information in stages. Defend your physiology, escalation, evidence and system reasoning.

Station opening
Examiner: “The PEWS is only in the yellow band. Why are you still worried?” [1]
Strong candidate (must-hit)
- Score is a detection tool, not a diagnosis and not a veto. [1]
- Incomplete observations under-estimate risk. [1]
- Caregiver concern is an independent signal associated with critical illness after vital-sign adjustment. [1]
- Trajectory and oxygen need matter more than a single band. [4] [9]
Weak candidate
