Arab Board Internal Medicine Clinical Exam common mistakes
Arab Board Internal Medicine Clinical Exam · Understand the traps and how to avoid them.
Committing to a single diagnosis and stopping the workup once the first plausible explanation appears, without explicitly excluding the dangerous alternatives (e.g., calling chest pain 'musculoskeletal' without addressing ACS, PE, or aortic dissection).
The oral station rewards a fast working diagnosis, and candidates feel pressure to sound decisive; pattern recognition fires before a systematic 'what would kill this patient' check.
What to do instead
After stating the leading diagnosis, verbally run a fixed 'must-not-miss' list for that presentation and state how each is being excluded (ECG, troponin, CTPA, etc.), before discussing management.
Resuscitating on paper with incomplete or wrong drug doses, infusion rates, or fluid volumes (e.g., adrenaline in anaphylaxis, insulin/fluid in DKA, hypertonic saline in hyponatremia), and being unable to state the endpoint for titrating therapy.
Candidates memorize the drug name but not the dose or the target; under exam stress they quote a plausible-sounding number rather than a rehearsed exact figure.
What to do instead
Build a one-page emergency drug card (drug, dose, route, rate, endpoint) for anaphylaxis, arrest, DKA, hyperkalemia, status epilepticus, and severe asthma, and rehearse it aloud until the numbers are automatic.
Presenting a disorganized case summary that buries the key finding, omits the pertinent negatives, and does not commit to a prioritized differential with reasons for and against each diagnosis.
Candidates present the history in the order they collected it rather than in the order the examiner needs it, and they list differentials without justification.
What to do instead
Use a fixed presentation template: one-line summary, key positives and pertinent negatives, then three prioritized differentials each with supporting and refuting features, then the next investigation and immediate management.
Misreading or failing to systematically interpret the ECG and ABG/acid-base data supplied in the stem, jumping to a single abnormality (e.g., calling a wide-complex tachycardia VT or SVT without criteria) instead of a structured read.
Candidates look for the 'answer' rather than applying a sequence; they lack a rehearsed reading routine and so miss rate, rhythm, axis, intervals, and morphology or the anion gap and compensation.
What to do instead
Rehearse a fixed ECG sequence (rate, rhythm, axis, intervals, hypertrophy, ischemia/infarct, comparison) and a fixed acid-base sequence (pH, pCO2, HCO3, anion gap, delta-delta, compensation) on practice tracings until it is automatic.
Under-investigating or over-investigating renal and electrolyte problems: failing to calculate the anion gap, urine osmolality, or fractional excretion, or ordering a renal biopsy before excluding prerenal and postrenal causes.
Candidates treat electrolyte questions as recall of a single value rather than a stepwise physiological algorithm, and they skip the cheap bedside calculations that localize the problem.
What to do instead
For every electrolyte or AKI stem, explicitly state the calculated indices (anion gap, urine Na/osmolality, FeNa, TTKG where relevant) and the prerenal-renal-postrenal stepwise exclusion before any invasive test.
Managing hyperglycemic emergencies and new diabetes with generic 'insulin and fluids' answers, omitting potassium replacement thresholds, the switch to dextrose-containing fluids, and the criteria for resolving DKA/HHS.
Candidates conflate outpatient diabetes titration with acute inpatient protocols and have not rehearsed the specific numeric triggers.
What to do instead
Memorize the DKA/HHS protocol numbers: fluid choice and rate, insulin infusion rate, potassium replacement threshold and rate, when to add dextrose, and resolution criteria (anion gap closure, pH, osmolality), and state them in every relevant station.
Missing the transfusion or anticoagulation decision point: failing to recognize when to transfuse, reverse anticoagulation, or hold therapy, and not stating the monitoring plan.
Hematology stations test thresholds and trade-offs rather than diagnoses, and candidates have not committed the trigger values (hemoglobin, platelet count, INR) to memory.
What to do instead
Build a threshold table for transfusion (RBC, platelet, FFP, cryoprecipitate), reversal agents (vitamin K, PCC, protamine, idarucizumab, andexanet), and heparin-induced thrombocytopenia, and state the indication, dose, and monitoring for each.
Answering infectious disease stations with an antibiotic name only, without source control, culture timing, duration, or de-escalation, and without addressing sepsis bundle elements.
Candidates treat 'which antibiotic' as the whole question and have not internalized that source, spectrum, and duration are equally examinable.
What to do instead
For every infection station, state: cultures before antibiotics, empiric regimen with dose, source control, sepsis bundle timing, review/de-escalation at 48–72 hours, and total duration.
Failing to recognize and act on red-flag neurological findings (e.g., thunderclap headache, focal deficit with time-critical thrombolysis window, meningism, or a deteriorating conscious level) and not stating the immediate imaging and treatment sequence.
Candidates anchor on a benign diagnosis and underestimate time-critical windows; they also lack a rehearsed stroke and meningitis pathway.
What to do instead
Rehearse the acute stroke pathway (door-to-CT time, thrombolysis window, thrombectomy criteria, blood pressure targets) and the meningitis pathway (dexamethasone timing, empiric regimen, isolation), and state the time-critical window explicitly in every relevant station.
Ignoring the geriatric and perioperative dimension: not assessing frailty, falls risk, polypharmacy, delirium, or capacity, and not stating perioperative risk stratification and medication management (e.g., anticoagulation bridging, beta-blocker continuation).
Candidates focus on the acute medical problem and treat the older or surgical patient as the same as a young medical patient, and they have not rehearsed the perioperative framework.
What to do instead
For every older or perioperative patient, add a fixed checklist: frailty and function, falls and delirium risk, medication review including anticoagulants and beta-blockers, capacity and goals of care, and a stated risk stratification tool with the resulting plan.
