ABP General Pediatrics common mistakes
ABP General Pediatrics · Understand the traps and how to avoid them.
Interprets a single height, weight, or head-circumference value as reassuring or alarming without plotting it on the correct sex-specific chart and comparing it with the previous visit's trajectory.
Recalled thresholds ('weight doubles by 5 months') feel sufficient, so the trend across visits - the finding most items hinge on - is never calculated.
What to do instead
At every growth stem, record the percentile or z-score and the change from the prior point; label a drop or rise across two major centile lines as abnormal until explained, and correct for prematurity under 24 months.
Omits scheduled screening because the child looks well - no autism-specific screen at 18 and 24 months, no lead or anemia risk assessment at 12 months, no vision or hearing screen at the recommended ages.
Clinical judgment is substituted for the Bright Futures periodicity table, and items deliberately present an asymptomatic child to test whether the schedule is applied.
What to do instead
Memorize the anchor visits (newborn, 2, 4, 6, 9, 12, 15, 18, 24 months, then annual) and the screens tied to each; answer from the schedule rather than from the physical exam.
Settles on ADHD, depression, or a purely psychosocial explanation before excluding medical mimics such as hearing or vision loss, sleep-disordered breathing, anemia, lead exposure, seizures, or abuse.
The behavioral vignette is vivid and the psychosocial stressors are salient, so anchoring occurs before the differential is closed.
What to do instead
Force a mimic list for each behavioral presentation, then choose the option that includes the indicated medical workup or names the red flag arguing against a primary psychiatric diagnosis.
Inverts time-critical priorities - antihistamine or steroid before epinephrine in anaphylaxis, imaging before stabilization, or antibiotics before cultures in a septic-appearing infant.
'Complete the workup' reasoning competes with 'treat the lethal problem first,' and the distractor choices are plausible and thorough.
What to do instead
For every emergency stem, rank actions by threat to airway, breathing, and circulation; the correct answer is the first action that changes outcome, not the most complete package.
Manages the single organ system and leaves out care-plan elements: written emergency plan, school accommodations, respite and family support, and transition planning for adolescents.
Biomedical details are more familiar than coordination tasks, and items bury the care-coordination option among plausible medication changes.
What to do instead
Apply a fixed complex-care checklist (emergency plan, school or IEP, home nursing, equipment, transition, family goals) and select the option that closes the largest gap in the plan.
Matches one buzzword to a diagnosis and ignores the time course, age, and associated findings that separate look-alikes such as intussusception from gastroenteritis or Kawasaki disease from a viral exanthem.
Illness scripts built from isolated features are retrieved faster than full discriminating-feature sets, and the stem's first line often carries a strong trigger word.
What to do instead
Build comparison tables for each look-alike pair (onset, fever pattern, exam, labs, next test) and answer only after checking which discriminating feature the stem actually supplies.
Chooses antibiotics by habit rather than by likely pathogen, site, and age; forgets duration, source control, or contact prophylaxis and reporting for communicable diseases.
Broad-spectrum choices feel safer, and public-health actions do not sit inside the acute-treatment frame.
What to do instead
For each infectious-disease item, name the organism, the site, and the drug, route, and duration; then ask whether prophylaxis, exclusion, or notification is also required.
Treats adolescent confidentiality either as absolute or as nonexistent instead of resolving consent, assent, and disclosure against the adolescent's capacity and the specific service sought.
A single memorized rule ('teens can consent to STI care') is applied to every situation without noting its limits, such as danger to self or others, mandated reporting, and payer explanation of benefits.
What to do instead
For each ethics item, state the governing principle, the adolescent's decisional capacity, and the legal exception; choose the option that preserves trust while disclosing only what is necessary and required.
Miscalculates weight-based resuscitation - adult doses, wrong concentration, fluid boluses in DKA or cardiac disease, or omitting dextrose for documented hypoglycemia.
Under time pressure, formulas are recalled approximately, and dose per kilogram is not separated from the volume or concentration.
What to do instead
Write the weight, the dose in mg/kg or mL/kg, and the concentration before choosing; remember that DKA and cardiac dysfunction get smaller, slower boluses and that glucose is a first-line drug.
Confuses true contraindications (anaphylaxis to a vaccine component, encephalopathy after pertussis) with precautions or minor illness, and reconstructs catch-up schedules without computing minimum intervals.
Fear of harm and outdated rules overshadow the short list of true contraindications, and catch-up requires interval arithmetic that is rarely rehearsed.
What to do instead
Memorize the short true-contraindication list, treat mild illness, fever, and antibiotic use as non-barriers, and apply minimum intervals plus the 4-day grace rule when rebuilding a delayed series.
