Branching cross-examination

This is a MedVellum formative viva. It is not an official RACP, MRCPCH, ABP, ACGME or RCPSC station, mark scheme, duration or pass standard. Release each update only after the candidate states the failing system, the immediate action and the reassessment endpoint. [1] [9]

Candidate brief

You are the senior paediatric clinician in a rural district emergency department. Speak as you would during resuscitation. Recognise the shared high-anion-gap acidosis and read the poison-specific signature; give the weight-based antidote on its trigger; decontaminate by poison; avoid the three lethal traps; and escalate to dialysis and retrieval before local support is exceeded. This is one continuous case. Each escalation branch leads to the next update. [9]
