393Fever + drooling + stridor + tripod position
ANSWEREPIGLOTTITIS → Secure airway (DO NOT examine throat)
DANGERFever + drooling + stridor + tripod = epiglottitis → secure airway, DO NOT examine the throat — the airway's emergency door.
TRAPCroup barks but doesn't drool or tripod.
394Epiglottitis in unimmunized children
ANSWERHAEMOPHILUS INFLUENZAE type b
ACRONYMEpiglottitis in unimmunized children = Haemophilus influenzae type b — the vaccine's absence reopens the disease.
TRAPViral croup is the stridor alternative, not epiglottitis' organism.
395Barking cough + inspiratory stridor + worse at night + steeple sign
ANSWERCROUP (laryngotracheobronchitis)
SOUNDBarking cough + inspiratory stridor + worse at night + steeple = croup — the seal's night bark.
TRAPEpiglottitis drools + trips; croup barks.
396Croup + barking cough + steeple sign
ANSWERCroup
PICTURECroup + barking + steeple = croup — the X-ray's steeple is the subglottic tower.
TRAPEpiglottitis shows the thumb sign instead.
397Staring gaze for seconds + normal neuro exam
ANSWERABSENCE SEIZURE → Ethosuximide
CLINCHStaring for seconds + normal neuro exam = absence seizure → ethosuximide — the pause button.
TRAPFocal seizures have motor/sensory features, not just a stare.
398Generalized tonic-clonic >5 minutes without regaining consciousness
ANSWERSTATUS EPILEPTICUS → IV diazepam/lorazepam
NUMBERGeneralized tonic-clonic >5 minutes without returning = status epilepticus → IV diazepam/lorazepam — the 5-minute cutoff.
TRAPA single seizure under 5 minutes isn't status.
399Status epilepticus
ANSWERIV diazepam/lorazepam
DANGERStatus epilepticus → IV diazepam/lorazepam — the need-to-stop benzodiazepine bolt.
TRAPPhenytoin is the second line after benzos.
400ADHD + always on the go + can't sit still + impulsive
ANSWERADHD
ACRONYMADHD + always on the go + can't sit still + impulsive = ADHD — the motor that never idles.
TRAPAnxiety is worry, not the hyperactive-impulsive triad.
401Autism + no speech + avoids eye contact + hand flapping
ANSWERAUTISM SPECTRUM DISORDER
CLINCHAutism + no speech + avoids eye contact + hand flapping = ASD — the social-communication disconnection.
TRAPHearing loss still seeks social connection; autism withdraws.
402Measles + Koplik spots + maculopapular rash starting behind ears + fever/cough/coryza
ANSWERMEASLES
PICTUREMeasles + Koplik spots + rash behind ears = measles — the spot within the mouth is the day-before tell.
TRAPRubella starts face-down with lymphadenopathy, no Koplik.
403Measles vaccine
ANSWERGiven at 9 months (EPI schedule)
NUMBERMeasles vaccine = 9 months (EPI schedule) — the EPI's measles month.
TRAPAt birth is BCG/OPV0, not measles.
404EPI at 9 months
ANSWERMeasles vaccine
NUMBEREPI at 9 months → measles vaccine — the month belongs to measles.
TRAPMMR boosters belong to later ages.
405Developmental milestone: draws a circle
ANSWER36 months
NUMBERDraws a circle = 36 months — the shape milestone ladder: circle 3, cross 4.
TRAP2 years is too early for the circle.
406Infant 9 months
ANSWERsits without support, transfers objects, says mama → Next: PINCER GRASP
CHAIN9 months: sits + transfers + says mama → next = pincer grasp — the tweezers arrive.
TRAPWalking is 12 months; pincer is the 9-month 'next'.
407Developmental milestones: sits + transfers + says mama at 9 months
ANSWERNext = pincer grasp
CLINCHMilestones at 9 months → next = pincer grasp — same ladder, same next step.
TRAPCruising/walking is the 12-month lane.
408Number of teeth at 2 years
ANSWER20 (all primary)
NUMBERTeeth at 2 years = 20 (all primary) — the full baby set by year two.
TRAPThe age×6 formula misleads; 20 is the answer.
409Gower sign + calf hypertrophy
ANSWERDUCHENNE MUSCULAR DYSTROPHY (X-linked recessive)
PICTUREGower sign + calf hypertrophy = Duchenne muscular dystrophy — the boy climbs his own legs.
TRAPBecker is milder and later, same gene.
410Muscular dystrophy + Gower sign
ANSWERX-linked recessive (dystrophin gene)
CLINCHMuscular dystrophy + Gower sign → X-linked recessive (dystrophin gene) — the X-carried muscle loss.
TRAPMyotonic is autosomal; Duchenne is X-linked.
411Pyloric stenosis + olive-shaped mass + vomiting 4-month-old
ANSWERPYLORIC STENOSIS → Ramstedt pyloromyotomy
PICTUREPyloric stenosis + olive-shaped mass + projectile vomiting in 4-month-old → Ramstedt pyloromyotomy — the olive and the split.
TRAPGERD doesn't project an olive.
412Kerosene oil ingestion
ANSWERCHEMICAL PNEUMONITIS → Beta-2 nebulization (NO gastric lavage)
DANGERKerosene ingestion → chemical pneumonitis → beta-2 nebulization, NO gastric lavage — breathing it out, never washing it out.
TRAPLavage/emesis with hydrocarbons is the aspiration death trap.
413Kerosene ingestion + respiratory distress
ANSWERBeta-2 nebulization (NO gastric lavage)
DANGERKerosene + respiratory distress → beta-2 nebulization, no lavage — the airway burns, not the stomach.
TRAPInduced vomiting after hydrocarbons is the classic lethal mistake.
414Lead poisoning + pica + constipation + basophilic stippling
ANSWERSerum lead level
CHAINLead poisoning + pica + constipation + basophilic stippling → serum lead level — the pica-to-stipple trail.
TRAPIron studies don't explain basophilic stippling.
415Celiac disease + diarrhea + FTT + late weaning
ANSWERDuodenal biopsy (gold standard)
CHAINCeliac + diarrhea + FTT + late weaning → duodenal biopsy — the gluten gut's gold standard.
TRAPAnti-TTG screens; the biopsy confirms.
416Gluten-sensitive enteropathy + FTT + diarrhea + protuberant abdomen
ANSWERCeliac disease → Duodenal biopsy
CLINCHGluten-sensitive enteropathy + FTT + diarrhea + protuberant abdomen → celiac → duodenal biopsy — the gluten belly's verdict.
TRAPCow-milk allergy is the differential, not this trigger's diagnosis.
417Child short + healthy + normal US:LS ratio
ANSWERGROWTH HORMONE DEFICIENCY
CLINCHChild short + healthy + normal US:LS ratio = growth hormone deficiency — the proportion-preserving short.
TRAPHypothyroid short has abnormal proportions and bone age.
418Bronchiolitis + wheeze + no fever/weight loss
ANSWERBRONCHIAL ASTHMA
CLINCHBronchiolitis + wheeze + no fever/weight loss = bronchial asthma — recurrent wheeze without infection = asthma.
TRAPBronchiolitis is first-episode with fever in RSV season.
419Asthma severe + unable to complete sentences + O2 sat 86%
ANSWERInhaled salbutamol + oxygen (first-line)
DANGERSevere asthma + can't complete sentences + SpO2 86% → inhaled salbutamol + oxygen first-line — the reliever and the air.
TRAPIV magnesium comes after SABA fails, not before.
420Acute asthma exacerbation + unable to speak + RR 32
ANSWERInhaled SABA (salbutamol) nebulizer
NUMBERAcute asthma + can't speak + RR 32 → inhaled SABA nebulizer — the inhaler first, always.
TRAPSteroids treat inflammation on a delay; SABA is the immediate breath.
421Asthma not responding to bronchodilators/steroids
ANSWERIV magnesium sulfate
CLINCHAsthma not responding to bronchodilators/steroids → IV magnesium sulfate — the refractory storm's brake.
TRAPAminophylline is the older, less-favored step.
422IMCI dehydration + restless + sunken eyes + slow skin pinch + drinks eagerly
ANSWERSOME DEHYDRATION → Plan B
NUMBERIMCI some dehydration: restless + sunken eyes + slow pinch + drinks eagerly → Plan B — ORS under observation.
TRAPPlan C is for severe; never skip to it, never give it lightly.
423Dehydration classification (IMCI)
ANSWERPlan A (none), Plan B (some), Plan C (severe)
ACRONYMIMCI dehydration classification = Plan A (none), B (some), C (severe) — the alphabet ladder.
TRAPPlan B for severe is the classic misstep.
424Kwashiorkor + edema + moon face + fatty liver + sparse hair
ANSWERKWASHIORKOR
PICTUREKwashiorkor + edema + moon face + fatty liver + sparse hair — the proteinless with a full-belly look.
TRAPMarasmus is the wasted, no-edema starvation.
425Nephrotic syndrome + periorbital puffiness + edema + ascites + protein +++
ANSWERPrednisolone (steroid first-line)
CHAINNephrotic + periorbital puffiness + edema + ascites + protein +++ → prednisolone first-line — the steroid-sensitive sieve.
TRAPDiuretics treat the symptom; steroids treat the disease.
426Minimal change disease
ANSWERSteroids first-line
CLINCHMinimal change disease → steroids first-line — minimal change, maximal response.
TRAPCyclophosphamide is the steroid-resistant step.
427Rickets + bowed legs + delayed dentition + widened wrists
ANSWERVITAMIN D deficiency
CLINCHRickets + bowed legs + delayed dentition + widened wrists = vitamin D deficiency — the D-bent bones.
TRAPHypophosphatasia is rare; D deficiency is the everyday answer.
428Short stature + healthy + normal US:LS ratio
ANSWERGrowth hormone deficiency
CLINCHShort stature + healthy + normal US:LS = growth hormone deficiency — the symmetric short.
TRAPConstitutional delay still has a story on bone age.
429Tooth count at 2 years
ANSWER20 teeth
NUMBERTooth count at 2 years = 20 teeth — the full primary set.
TRAPThe age×6 formula misleads; 20 is the hard answer.
430Cystic fibrosis + recurrent respiratory infections + pancreatic insufficiency + elevated sweat chloride
ANSWERCYSTIC FIBROSIS (CFTR mutation)
PICTURECF + recurrent infections + pancreatic insufficiency + elevated sweat chloride = cystic fibrosis — the salty skin print.
TRAPPrimary ciliary dyskinesia has dextrocardia and no pancreatic failure.
431Pompe disease + acid maltase deficiency + glycogen in lysosomes
ANSWERPOMPE DISEASE
CLINCHPompe disease + acid maltase deficiency + glycogen in lysosomes — the lysosomal glycogen storage.
TRAPvon Gierke stores in cytoplasm, not lysosomes.
432Sore throat 2 weeks ago + edema + dark scanty urine + BP elevated
ANSWERPSGN
NUMBERSore throat 2 weeks ago + edema + dark scanty urine + BP up = PSGN — the 2-week echo again.
TRAPIgA hits within days, not weeks.
433Scabies + nocturnal itching + finger webs + family affected
ANSWERPermethrin cream (treatment of choice)
CLINCHScabies + nocturnal itching + finger webs + family affected → permethrin cream — the mite's night itch, the cream for all.
TRAPAntihistamines calm the itch; permethrin kills the mite.
434Diphtheria + gray pseudomembrane
ANSWERDiphtheria antitoxin + antibiotics
DANGERDiphtheria + gray pseudomembrane → antitoxin + antibiotics — the membrane's double treatment.
TRAPAntibiotics alone leave the toxin to kill the heart.
435Hydrocephalus + enlarged head + sunset sign
ANSWERCSF accumulation
PICTUREHydrocephalus + enlarged head + sunset sign = CSF accumulation — the pressure's fluid.
TRAPFamilial macrocephaly has no sunset sign or pressure.
436Strawberry tongue + sandpaper rash + fever
ANSWERSCARLET FEVER (Group A Strep)
CLINCHStrawberry tongue + sandpaper rash + fever = scarlet fever (Group A strep) — the strawberry-sandpaper pair.
TRAPKawasaki has strawberry tongue but no sandpaper rash.
