MDCG Medical Exam study guide
MDCG Medical Exam · Work through your exam, one topic at a time.
The MDCG Medical Exam is a multiple-choice assessment built around the competencies expected of a medical credentialing candidate: legal and ethical foundations, day-to-day patient care, diagnostic reasoning, therapeutics, public health and prevention, documentation and administration, emergency and critical care, and quality and safety. The eight domains are not weighted equally - diagnostic testing and clinical reasoning carries the largest share, followed by law/ethics, patient care, and pharmacology - so a candidate who spreads effort evenly will under-prepare for the sections that decide the outcome. The MDCG Medical Exam study guide has 8 sections and about 3,353 words.
01Medical Law, Regulation, and Ethics
Law, regulation, and ethics questions ask you to apply rules to a concrete bedside decision: who may consent, when confidentiality yields, what makes a negligence claim succeed, and how research and commercial relationships are governed. The answer usually turns on one decisive fact in the stem, so read for capacity, age, urgency, and who is asking.
444 words, about 2 min02Patient Care and Clinical Management
This domain checks whether you can move from an unstructured complaint to a safe, prioritized plan, and whether you can run chronic disease and care transitions without letting the urgent item slip. Questions reward triage judgment and a defensible differential more than exhaustive lists.
403 words, about 2 min03Diagnostic Testing and Clinical Reasoning
This domain tests quantitative reasoning about tests: what sensitivity, specificity, predictive values, and likelihood ratios mean, how prevalence changes interpretation, and when a test is worth ordering at all. Sensitivity = TP/(TP+FN); specificity = TN/(TN+FP).
398 words, about 2 min04Pharmacology and Therapeutics
Questions probe whether you can predict drug behavior in a specific patient: absorption and clearance, half-life and steady state, interactions, dose adjustment in organ failure, and recognition of adverse effects. Mechanism questions usually reduce to a clinical consequence.
399 words, about 2 min05Public Health, Epidemiology, and Prevention
This domain asks you to read population data critically: measure disease frequency, choose and interpret study designs, quantify association, and detect bias. Prevention questions test the levels of prevention and the criteria for a worthwhile screening program.
404 words, about 2 min06Medical Documentation, Coding, and Administration
This domain covers the record as a legal document and as a billing instrument: what must be documented, how corrections are made, how visit levels are supported, and how coding conventions and privacy rules apply. Questions often present a note and ask what is wrong with it or what may be billed.
442 words, about 2 min07Emergency and Critical Care Medicine
This domain tests time-critical recognition and ordered action: airway, breathing, circulation, then focused history, with correct drug and dose selection. Questions frequently hinge on which action comes first or on a dose that must be exact.
421 words, about 2 min08Quality Improvement and Patient Safety
This domain asks how care systems fail and how they are measurably improved: the frameworks used to describe quality, the tools for analyzing incidents, and the measurement discipline that distinguishes real improvement from random variation. Donabedian frames quality as structure (resources), process (what is done), and outcome (what results).
