Internado Rotatorio Medicina Bolivia common mistakes
Internado Rotatorio Medicina Bolivia · Understand the traps and how to avoid them.
In pediatric cases, applying adult maintenance fluid and drug doses directly (e.g., giving a fixed adult ampicillin dose to a 2-year-old) instead of calculating by weight (mg/kg or mL/kg).
Candidates memorize adult hospital protocols during Medicina Interna rotations and revert to them under time pressure; they forget that pediatric therapeutics is weight-based and changes with age (immature hepatic/renal clearance in neonates).
What to do instead
Before answering any pediatric item, write the weight and the mg/kg or mL/kg calculation explicitly on scratch paper, state the maximum adult ceiling, and check the result against a standard pediatric formulary range; practice 20 weight-based dose calculations per week until automatic.
Reading a clinical vignette and committing to a diagnosis before finishing the stem, then ignoring the one finding that contradicts it (e.g., anchoring on 'appendicitis' when the pain migrated and the pregnancy test is positive).
Exam stems deliberately embed a 'distractor-consistent' early picture; premature closure is reinforced by time pressure and by pattern-matching to classic textbook presentations.
What to do instead
Use a fixed two-pass method: first pass read the entire stem and list key positives and negatives, second pass generate at least two differentials and eliminate with the findings; explicitly ask 'what does not fit?' before selecting.
Managing obstetric emergencies with non-obstetric priorities, e.g., treating severe preeclampsia with antihypertensives alone while delaying magnesium sulfate, or choosing a diagnostic imaging study before stabilizing an eclamptic patient.
Candidates separate 'internal medicine' from 'obstetrics' in their mental filing system and forget that maternal stabilization and seizure prophylaxis take precedence; they also under-recognize that delivery is the definitive treatment.
What to do instead
Drill a fixed sequence for each obstetric emergency (preeclampsia/eclampsia, hemorrhage, sepsis): airway and hemodynamics, magnesium sulfate loading for seizure prophylaxis, antihypertensives for severe hypertension, then delivery planning; rehearse aloud with timed cases.
Answering public health questions with clinical reasoning instead of epidemiological reasoning: confusing incidence with prevalence, sensitivity with positive predictive value, or relative with absolute risk reduction.
Clinical training emphasizes individual diagnosis and treatment, so candidates never practice 2x2 table arithmetic or interpreting screening metrics under exam conditions.
What to do instead
Before selecting, draw the 2x2 table and compute the requested measure; state in writing whether the question asks about occurrence (incidence), burden (prevalence), test performance (sens/spec), or post-test probability (PPV/NPV). Do 15 table-based items weekly.
Choosing the 'most complete' or newest-sounding drug instead of the first-line agent according to Bolivian national guidelines and the WHO essential medicines list (e.g., selecting a broad-spectrum antibiotic for uncomplicated community-acquired pneumonia in an outpatient).
Candidates study from international sources with different formularies and availability, and equate 'more potent' with 'better'; they also fail to consider cost and access in the Bolivian public system.
What to do instead
Build a one-page first-line drug table per major syndrome (pneumonia, UTI, tuberculosis, malaria, hypertension, diabetes) based on the national clinical guidelines and the petitorio nacional; review it before each exam and justify each drug choice by indication, spectrum, and availability.
Ignoring informed consent, confidentiality, or the patient's decision-making capacity in bioethics items, and answering with what the doctor thinks is medically best rather than what the patient has a right to choose.
The hidden curriculum of hospital wards rewards paternalistic 'doctor knows best' decisions; candidates have little practice applying the four principles to concrete conflicts and confuse legal obligation with ethical obligation.
What to do instead
For every ethics vignette, explicitly identify: capacity, voluntariness, information given, and the least restrictive option; then apply autonomy first for competent adults, and document the reasoning. Practice 10 cases on refusal of treatment, minors, and confidentiality breaches.
Failing to recognize and act on red-flag vital signs and triage categories in emergency items, e.g., discharging a patient with hypotension plus tachycardia, or ordering tests before airway and circulation assessment.
Candidates learn emergencies as disease lists rather than as a systematic ABCDE approach, and exam stems with distracting detail pull attention away from abnormal vital signs.
What to do instead
Adopt a mandatory first step: circle every abnormal vital sign in the stem and assign a triage level before reading the options; then answer using the ABCDE sequence. Practice rapid triage with 10 vitals-only vignettes per session.
Missing the legal and normative obligations in Bolivia-specific items: failure to report notifiable diseases, to complete the death certificate correctly, or to recognize when a medicolegal report (denuncia) is required for violence or suspected crime.
Forensic and health-law content is taught briefly and inconsistently across rotations, and candidates assume clinical competence alone is tested; they also confuse the roles of the médico forense and the treating physician.
What to do instead
Memorize a short list: notifiable diseases and reporting channels, death certificate fields and who signs, mandatory reporting of violence and suspected poisoning, and documentation standards for the clinical record; review the Ley 3131 and national health norms with a one-page summary.
In general surgery items, choosing an imaging or laboratory test before resuscitation and surgical evaluation, or misclassifying the urgency of a surgical abdomen (e.g., observing a patient with peritonitis).
Candidates overvalue diagnostic certainty and undervalue the 'surgical abdomen = surgical consultation' principle; they also underuse the history and physical exam in favor of tests.
What to do instead
Apply a fixed sequence for acute abdomen: stabilize, examine, decide whether the abdomen is surgical, and call surgery early; reserve imaging for stable patients where it changes management. Practice classifying 20 acute abdomen vignettes as operative, urgent, or elective.
In primary care items, managing only the presenting complaint and omitting prevention, chronic disease follow-up, and family/community context (e.g., not offering vaccination, screening, or lifestyle counseling when the visit is for a minor complaint).
Hospital-based training rewards acute problem-solving, and candidates treat primary care as 'minor medicine' rather than comprehensive, continuous, family-centered care.
What to do instead
For every primary care vignette, run a checklist: acute problem, chronic conditions, prevention/screening, vaccination, mental health, and family/social determinants. Answer the option that integrates these levels rather than the one that only treats the symptom.
