MOHAP Doctor Exam common mistakes
MOHAP Doctor Exam · Understand the traps and how to avoid them.
Committing to a single diagnosis and stopping the reasoning once a plausible 'textbook' disease fits the stem, without weighing competing options that share the same presentation.
High-volume candidates pattern-match quickly to familiar vignettes, and the exam deliberately builds stems where two diagnoses fit superficially; the first match feels rewarding and closes off deliberation.
What to do instead
Before selecting, write one line for each remaining option stating the single finding that would rule it in or out, and only answer when one option survives all stated findings.
Answering the 'next step' question with the definitive treatment instead of the immediate next action (or vice versa), e.g. choosing surgery when the question asks what to do first in an unstable patient.
Candidates read the clinical scenario and jump to the final management they know best, skipping the exact wording of the question stem.
What to do instead
Underline the question's operative phrase (first step, best initial test, most appropriate definitive management) and classify each option as resuscitation, investigation, or definitive therapy before choosing.
Missing the hemodynamic status in a surgical stem and selecting an elective workup (e.g. CT) for a patient described as hypotensive or peritonitic.
Attention is drawn to the diagnostic puzzle and away from vital signs, which are placed early in the stem and read quickly.
What to do instead
Scan every surgical stem for blood pressure, heart rate, and peritoneal signs first; if unstable or peritonitic, prioritize resuscitation and immediate surgical involvement over imaging.
Misassigning gestational age when dating a pregnancy, leading to the wrong trimester-specific management or diagnostic threshold.
Candidates calculate from LMP inconsistently or ignore a stated ultrasound dating, and trimester cutoffs change which tests and treatments are correct.
What to do instead
Use the stated ultrasound dating when provided, otherwise calculate from LMP, and write the gestational age in weeks explicitly before answering any obstetric question.
Failing to recognize pregnancy as a contraindication or risk modifier when selecting a drug or imaging test in a female of reproductive age.
The stem may mention pregnancy only indirectly (missed period, positive beta-hCG), and candidates default to the non-pregnant management they know well.
What to do instead
For every female patient of childbearing age, actively check for pregnancy status in the stem and screen each drug option against pregnancy safety before selecting.
Applying adult vital-sign and laboratory thresholds to a pediatric patient, or misjudging age-specific normal values such as respiratory rate and hemoglobin.
Adult medicine dominates candidate training and reference ranges, so normal pediatric values are recalled imprecisely under time pressure.
What to do instead
Memorize age-banded normal ranges for respiratory rate, heart rate, and hemoglobin, and classify any abnormal value against the child's stated age before interpreting it.
Missing dehydration severity in a pediatric stem and choosing the wrong fluid route or rate (oral vs. bolus vs. maintenance).
Mild and moderate dehydration look similar in a short vignette, and candidates anchor on the diagnosis rather than grading severity from the stated signs.
What to do instead
Grade dehydration explicitly from the listed signs (mental status, mucous membranes, tears, capillary refill, urine output) and match the route and rate to that grade.
Ignoring a single discriminating laboratory or imaging finding buried in an otherwise long stem, then choosing an answer that contradicts it.
Stems are long and candidates skim, so a normal or abnormal value that eliminates the leading option is overlooked.
What to do instead
Read the stem twice: first for the story, second specifically to list every numeric or qualitative result, then verify the chosen answer is consistent with all of them.
Selecting a management option that is contraindicated by a comorbidity or concurrent medication stated in the stem.
Candidates focus on treating the primary problem and treat comorbidities as background detail rather than as constraints on the answer.
What to do instead
Before finalizing, list the patient's comorbidities and current medications and check the chosen option against each one for contraindication or interaction.
Running out of time because time is spent disproportionately on a few difficult items while easier items later in the block are left unanswered.
Candidates feel compelled to solve each question fully before moving on, and difficult stems absorb minutes that could secure several easier marks.
What to do instead
Set a per-question time budget, flag and move past any item exceeding it, and reserve the final minutes for flagged items and for confirming no blanks remain.
