Residencias CABA Medicina common mistakes
Residencias CABA Medicina · Understand the traps and how to avoid them.
Answering epidemiologic questions about Argentina with the general 'textbook' figure (e.g., choosing a generic incidence or mortality ranking) instead of the current national data for the CABA/Argentina context.
Study material is often translated or international, so candidates memorize global figures and never anchor them to Argentine surveillance data (boletines epidemiológicos, estadísticas vitales).
What to do instead
Build a one-page 'Argentina numbers' sheet (leading causes of death, notifiable diseases, vaccination schedule) updated from official national sources, and review it weekly.
Choosing the most sensitive test when the question asks for the most specific or confirmatory study, or vice versa.
Candidates read 'diagnóstico de...' and reflexively pick the gold standard without checking whether the stem asks to screen, rule out, or confirm.
What to do instead
Before answering, underline the exact verb in the stem (descartar/confirmar/tamizar/monitorizar) and match it to sensitivity vs specificity vs gold standard.
Jumping to the definitive treatment in an unstable patient instead of the first stabilization step (ABC, fluid resuscitation, immediate referral).
Clinical reasoning is taught around final diagnoses, so the sequence of priorities gets compressed under time pressure.
What to do instead
For every emergency stem, write the first three actions in ABC order before reading the options, then pick the option that matches step one.
Selecting a treatment option that is contraindicated by a detail in the stem (allergy, pregnancy, renal failure, age) because the drug is otherwise first-line.
Pattern-matching to the 'classic' drug overrides careful reading of comorbidities and contraindications.
What to do instead
After choosing an answer, do a mandatory 10-second contraindication pass: pregnancy, renal/hepatic function, allergy, age, interactions.
Confusing indications for surgery versus conservative management in abdominal pain scenarios (e.g., choosing observation when there are signs of peritonitis or hemodynamic instability).
Candidates memorize diagnoses but not the decision thresholds that convert a diagnosis into a surgical emergency.
What to do instead
Create a table of 'absolute surgical indications' (peritonitis, perforation, ischemia, obstruction with compromise) and drill decision rules, not just diagnoses.
Applying adult drug doses, fluid volumes, or vital-sign thresholds to pediatric patients.
Adult medicine dominates study time, and pediatric weight-based dosing and age-specific normal ranges are less rehearsed.
What to do instead
Practice a fixed set of pediatric calculations (mg/kg, maintenance fluids by Holliday-Segar, normal HR/RR by age) until automatic.
Mismanaging obstetric emergencies by delaying definitive treatment (e.g., waiting for labs before acting on suspected ectopic pregnancy or postpartum hemorrhage).
The reflex to 'confirm before acting' is appropriate elsewhere but dangerous in obstetrics, where time-critical decisions dominate.
What to do instead
Memorize the immediate action bundle for each obstetric emergency (ectopic, PPH, preeclampsia/eclampsia, shoulder dystocia) and rehearse it as a sequence.
Answering ethics and legal questions with personal moral preference rather than the framework of Argentine law (consent, confidentiality, minors, reporting obligations).
These topics feel like 'common sense', so candidates skip formal study of the legal framework and its exceptions.
What to do instead
Study the specific legal rules (informed consent, assent in minors, mandatory reporting, confidentiality exceptions) and answer strictly from the legal standard.
Failing to identify the single best answer when two options are both 'true', by not ranking options against the most likely diagnosis or the most appropriate next step.
Candidates evaluate each option in isolation for correctness instead of comparing them relative to the stem's exact question.
What to do instead
When two options seem correct, re-read the stem's precise ask and eliminate the option that answers a different question or is a later step.
Running out of time because of over-investing in long clinical vignettes while leaving public health and basic science items unanswered.
Vignette questions consume disproportionate time, and candidates don't practice pacing across the full mixed-domain exam.
What to do instead
Do timed full-length practice runs with a hard per-question cap, flagging long vignettes to return to, and never leave blanks.
