FRCEM Paediatrics SLO 5: Febrile Child High-Yield Guide

Paediatric emergencies account for 30 questions (16.7%) in the FRCEM SBA, making SLO 5 one of the most heavily weighted domains. Yet it's where most adult emergency medicine trainees feel least confident.

The challenge is real: you've spent years managing adult presentations, and suddenly you're expected to know weight-based drug dosing, developmental milestones, and safeguarding nuances—all at consultant level.

This guide breaks down the highest-yield SLO 5 topics that actually appear in FRCEM questions.

Why SLO 5 Feels Difficult

Most EM trainees come from adult medicine backgrounds. Paediatrics represents a different clinical language: vital signs vary by age, drug doses require calculations, and seemingly minor presentations can represent serious pathology.

The good news: SLO 5 topics follow predictable patterns. Master the core presentations and you'll recognize variations in exam questions.

The Febrile Child: NICE Traffic Light System

Every FRCEM candidate must know the NICE fever in under 5s guideline. Questions present clinical scenarios requiring risk categorization and appropriate management.

Risk Categorization & Management

Risk Level

Clinical Features

Management Strategy

Green (Low)

Normal color, activity, and hydration. Responds normally to social cues. Strong cry or not crying.

Home care with safety-netting advice.

Amber (Intermediate)

Reduced activity, not responding normally to cues. Decreased urine output, dry mucous membranes, poor feeding (infants), or fever ≥5 days.

Face-to-face assessment. Consider investigations. Safety-netting is essential.

Red (High)

Reduced consciousness, pale/mottled/ashen appearance, weak continuous cry, grunting, RR >60/min, non-blanching rash, bulging fontanelle, neck stiffness, or focal neurological signs.

Urgent assessment. Full septic screen (bloods, urine, consider LP). Consider admission and parenteral antibiotics.

FRCEM Question Angles

Questions test correct risk categorization, investigation pathways, when to give antibiotics, and when admission is mandatory.

Critical point: Any infant under 3 months with fever ≥38°C is high risk regardless of appearance. This requires full septic workup and admission.

Weight-Based Drug Dosing

FRCEM questions will provide the child's weight and clinical scenario. You must calculate the correct dose or recognize incorrect dosing in the multiple-choice options.

6 Essential Emergency Doses to Memorize

Drug

Indication

Dose Calculation

Maximum Dose

Paracetamol

Analgesia/Antipyretic

Loading: 20mg/kg. Maintenance: 15mg/kg (every 4-6 hrs)

90mg/kg/day or 4g/day

Ibuprofen

Analgesia/Antipyretic

10mg/kg (every 6-8 hrs)

40mg/kg/day

Adrenaline

Anaphylaxis

10 micrograms/kg IM (0.01ml/kg of 1:1000)

500 micrograms (0.5ml)

Fluid Bolus

Shock

20ml/kg of 0.9% sodium chloride

Repeat up to 40-60ml/kg if ongoing

Ceftriaxone

Meningitis

80mg/kg IV/IM

4g

Lorazepam

Status Epilepticus

0.1mg/kg IV

4mg

Dexamethasone

Croup

0.15mg/kg oral (usually 150 micrograms/kg)

N/A

Calculation tip for the exam: If a 15kg child needs maintenance paracetamol, the math is simply 15 × 15 = 225mg.

Safeguarding Red Flags

Safeguarding contributes 5-7 questions within SLO 5. The FRCEM tests your ability to recognize concerning patterns, not to act as a forensic detective.

Physical Abuse Indicators

Concerning injury patterns:

  • Bruising in non-mobile infants (pre-cruising babies shouldn't have bruises)

  • Bruising to soft tissues: ears, neck, genitals, buttocks

  • Pattern bruising: hand marks, bite marks

  • Multiple injuries at different healing stages

  • Injuries inconsistent with developmental stage or history

  • Delay in seeking medical attention

Fractures raising concern:

  • Rib fractures (especially posterior)

  • Metaphyseal fractures

  • Fractures in non-mobile infants

  • Multiple fractures at different stages

Burns

  • Clear demarcation lines (immersion)

  • Symmetrical distribution

  • Glove and stocking pattern

  • Burns to genitals, buttocks, soles

  • Delay in presentation

Actions When Concerned

  • Ensure child safety (admit if immediate risk)

  • Document thoroughly

  • Senior ED review

  • Contact safeguarding team

  • Consider skeletal survey (under 2 years, suspected physical abuse)

Remember: You don't diagnose abuse—you recognize concern and escalate appropriately.


Respiratory Emergencies

Croup

Presentation: Barking cough, inspiratory stridor, hoarse voice. Ages 6 months-3 years, worse at night.

Management:

  • Oral dexamethasone 0.15mg/kg (single dose)

  • Nebulized adrenaline if severe (5ml of 1:1000)

  • Observe 2-4 hours post-adrenaline

Bronchiolitis

Presentation: Under 12 months, coryzal symptoms, cough, wheeze, respiratory distress, feeding difficulties.

Management:

  • Supportive care only

  • Oxygen if SpO2 <92%

  • NG/IV fluids if not feeding

  • Admission if high-risk or moderate-severe distress

Important: No salbutamol, steroids, or antibiotics in uncomplicated bronchiolitis.

Asthma Exacerbation

Severity:

  • Moderate: SpO2 ≥92%, talking in sentences

  • Severe: SpO2 <92%, too breathless to talk, HR >140 (age 2-5) or >125 (>5 years)

  • Life-threatening: Silent chest, poor respiratory effort, altered consciousness

Management:

  • Oxygen to maintain SpO2 94-98%

  • Salbutamol (10 puffs via spacer or nebulizer)

  • Oral prednisolone: 20mg (2-5 years), 30-40mg (>5 years)

  • IV magnesium if severe/life-threatening.


Developmental Milestones

The FRCEM occasionally tests whether a child's development is appropriate for their age, primarily to assess if an injury is consistent with their physical capabilities.

Key milestones:

  • 6 weeks: Social smile, fixes and follows

  • 6-9 months: Sits unsupported, stranger anxiety

  • 12 months: Stands with support, says "mama/dada"

  • 18 months: Walks independently, several words

  • 2 years: Runs, 2-3 word sentences

  • 3 years: Pedals tricycle, 3-word sentences

Use: Recognizing developmental delay, assessing whether injury consistent with developmental stage.

Common FRCEM SLO 5 Mistakes

1. Not recognizing age <3 months + fever as high risk
Regardless of appearance, infants under 3 months with fever ≥38°C require full workup and admission.

2. Treating bronchiolitis with salbutamol
Bronchiolitis is viral. Salbutamol doesn't work. Management is supportive only.

3. Missing safeguarding red flags
Non-mobile infants shouldn't have bruises. Inconsistent history is a red flag. When in doubt, escalate.

4. Weight-based dosing errors
Always calculate doses. Don't guess. Check maximum doesn't exceed adult doses.

5. Forgetting traffic light nuances
A child can look well but still be amber/red risk based on specific features (age <3 months, fever >5 days, reduced urine).

SLO 5 Preparation Strategy

Focus areas:

  • Master traffic light system thoroughly

  • Memorize 8-10 essential weight-based doses

  • Understand safeguarding red flags

  • Know respiratory emergency management

Practice volume: Given SLO 5 represents 30 questions (16.7%), approximately 300-400 paediatric questions during your preparation ensures adequate exposure.

Frequently Asked Questions

Do I need a paediatrics textbook?
If paediatrics is a weak area, "Paediatric Emergency Medicine" by Cameron et al. is excellent. Otherwise, focused SLO 5 question practice with good explanations suffices.

What if I've never worked in paediatric ED?
Many successful candidates haven't. Focus on guideline-based learning (NICE, APLS) and systematic question practice.

Are paediatric vital signs tested?
Not explicitly, but you need to recognize abnormal vital signs for age when assessing severity.

Should I memorize all weight-based doses?
Memorize the 8-10 most common emergency drugs. FRCEM doesn't expect every paediatric drug dose.

How many SLO 5 questions should I practice?
Approximately 300-400 paediatric questions ensures comprehensive exposure to patterns.


SLO 5 feels daunting because it represents unfamiliar territory for most adult EM trainees. However, the topics tested follow predictable patterns: febrile child assessment, safeguarding recognition, respiratory emergencies, and weight-based dosing.

Master the traffic light system, learn essential drug doses, recognize safeguarding red flags, and understand common respiratory presentations. These core areas account for 25+ of the 30 SLO 5 questions.

Systematic question practice builds pattern recognition faster than textbook reading alone. Seeing how FRCEM presents paediatric scenarios teaches you what to look for.
