D236 OA Test-Taking Strategy
The D236 Pathophysiology Objective Assessment is a high-stakes multiple-choice exam designed to test both
your recall of foundational pathophysiology and your ability to apply concepts to clinical scenarios. Approaching
the exam strategically can improve your performance significantly. The following evidence-based techniques will
help you maximize your score, manage your time, and avoid common pitfalls that cause well-prepared students to
lose points on questions they actually know.
Time Management
Allocate approximately 36-45 seconds per question. Do not let a single difficult item consume more than 90 seconds.
Mark it for review and move on; returning with fresh eyes often resolves the answer. Budget the last 10 minutes of the
exam to revisit flagged items.
Process of Elimination
Eliminate the two most clearly wrong options first. This raises your chance of a correct guess from 25% to 50%. Many
distractors contain absolute terms ('always', 'never', 'only') that are rarely correct in clinical medicine. Eliminate options
that contradict basic physiology.
Keyword Spotting
Underline or note qualifier words such as 'most likely', 'initial', 'first', 'primary', 'best', and 'least'. These keywords
change the correct answer. For example, 'initial action' often prioritizes ABCs (Airway, Breathing, Circulation), while
'most likely diagnosis' focuses on prevalence.
Clinical Scenario Approach
Read the stem carefully; identify the age, sex, key symptom, and key laboratory/imaging finding before reading
options. Form a preliminary answer in your mind, then look for it among the choices. This protects you from being
misled by plausible distractors.
Prioritization Frameworks
Use ABCs and Maslow's hierarchy for prioritization questions. Physiologic needs always outrank psychosocial
concerns. For shock, hypoxia, and airway compromise, address the immediate life threat first; psychological support
follows.
Answer the Question Asked
Some options may be TRUE statements that do not answer the question. Verify that the selected option responds to the
specific ask. Avoid options that are correct in isolation but irrelevant to the stem.
Watch for 'Except' and 'Not'
Negatively phrased questions ('Which is NOT...?', 'All of the following EXCEPT...') are common in pathophysiology
exams. Read these stems twice to ensure you are selecting the exception, not the rule. Briefly rephrase the question in
your own words.

[CELLULAR PATHOLOGY] Q1. A patient has chronic atrophic gastritis. The
gastric mucosal cells have decreased in size due to decreased nutrient supply.
Which cellular adaptation is this?
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
Answer: C |
Rationale: Atrophy is a decrease in cell size due to decreased nutrient supply, disuse, or reduced trophic
signals. Hypertrophy is an increase in cell size (e.g., cardiac muscle in hypertension); hyperplasia is an
increase in cell number (e.g., endometrial proliferation); metaplasia is reversible replacement of one adult cell
type by another (e.g., Barrett esophagus).
[CELLULAR PATHOLOGY] Q2. Which cellular adaptation involves a
reversible replacement of one adult cell type by another, often in response to
chronic irritation?
A. Dysplasia
B. Metaplasia
C. Anaplasia
D. Hypertrophy
Answer: B |
Rationale: Metaplasia is the reversible substitution of one differentiated adult cell type for another, typically
as an adaptive response to chronic irritation (e.g., squamous metaplasia of bronchial columnar epithelium in
smokers). Dysplasia is disordered growth (pre-malignant); anaplasia is loss of differentiation (malignant);
hypertrophy is increased cell size.
[CELLULAR PATHOLOGY] Q3. A biopsy of the lower esophagus in a
patient with chronic GERD shows intestinal-type columnar epithelium
replacing the normal squamous epithelium. This is most accurately described
as:
A. Barrett esophagus, an example of metaplasia
B. Esophageal dysplasia, an early cancer
C. Squamous cell hyperplasia, benign
D. Esophageal atrophy

Answer: A |
Rationale: Barrett esophagus is the classic example of metaplasia, where chronic acid exposure causes
normal squamous epithelium to be replaced by intestinal-type columnar epithelium. This is adaptive but
pre-malignant, increasing risk of adenocarcinoma. Dysplasia would imply disordered atypical cells;
hyperplasia would be increased numbers of the same cell type; atrophy would be cell shrinkage.
