Topic module

The Acutely Unwell Child

Recognise paediatric deterioration, sepsis, respiratory distress, dehydration and neurological emergencies using age-aware assessment.

Long-form learning
Concept to Risk to Memory to Check-up

How to prepare for PLAB 1

Practise recognising the immediate clinical task, ruling in or out dangerous alternatives, choosing the safest next step and closing the loop.

Core concepts

Concept 1

Children compensate before deteriorating rapidly, so appearance, work of breathing, circulation and trend matter.

Exam cue: Use a structured paediatric assessment and escalate early.

Concept 2

Drug and fluid decisions require weight, age and maximum-dose checks.

Exam cue: Check weight-based arithmetic and the final clinically plausible dose.

Risk pitfalls and guardrails

Relying on one normal observation in a child who looks unwell.

Guardrail: Avoid an option that names a plausible diagnosis but ignores physiology, contraindications, competence, patient priorities or follow-up.

Calculating from an estimated or wrong-unit weight.

Guardrail: Avoid an option that names a plausible diagnosis but ignores physiology, contraindications, competence, patient priorities or follow-up.

Memory anchors

What is the paediatric assessment triangle?

Appearance, work of breathing and circulation to skin.

What suggests serious illness in a child?

Abnormal interaction, respiratory effort, perfusion, neurological state or concerning trajectory.

How is a paediatric dose checked?

Correct weight, mg-per-kg calculation, route, frequency and maximum dose.

What matters in dehydration?

Clinical deficit and shock, ongoing losses, oral tolerance and electrolyte risk.

What makes discharge safe?

Clinical improvement, caregiver understanding, clear warning signs and reliable follow-up.

Checkpoint rule

Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
