PreDiagnostic Exam Case Study Part 1 |
2026 Update with complete solutions.
1. The first step in the clinical reasoning process is:
a) Ordering diagnostic tests
b) Generating a differential diagnosis
c) Gathering patient data (history and physical exam)
d) Initiating treatment
Answer: c) Gathering patient data
Rationale: Clinical reasoning begins with data acquisition – history,
physical exam, and review of available records. Without accurate
data, subsequent reasoning is flawed.
2. The dual-process theory of clinical reasoning describes:
a) Analytical (systematic, slow) and non-analytical (intuitive,
pattern recognition) thinking
,Page 2 of 63
b) Left brain vs. right brain
c) Inductive and deductive reasoning only
d) Individual vs. team decision-making
Answer: a) Analytical and non-analytical
Rationale: Kahneman, Croskerry. Experienced clinicians often use
pattern recognition (Type 1), but must also use analytic (Type 2)
for complex or atypical cases.
3. Cognitive bias that leads a clinician to latch onto an initial
diagnosis despite later contradictory evidence is called:
a) Confirmation bias
b) Anchoring bias
c) Availability bias
d) Framing effect
Answer: b) Anchoring bias
Rationale: Anchoring is the tendency to rely heavily on the first
,Page 3 of 63
piece of information encountered. It can be mitigated by deliberate
generation of alternative differentials.
4. Which strategy best reduces diagnostic error?
a) Relying solely on intuition
b) Using a structured differential diagnosis checklist (e.g., “don’t
miss” list)
c) Ordering all available tests
d) Avoiding consultation with colleagues
Answer: b) Structured differential generation
Rationale: Explicitly listing differentials and using metacognitive
checklists (e.g., “what else could this be?”) reduces premature
closure and anchoring.
5. The illness script is a mental framework that includes:
a) Patient’s insurance information
b) Predisposing factors, pathophysiology, and clinical features of
a disease
, Page 4 of 63
c) Hospital protocols
d) Billing codes
Answer: b) Predisposing factors, pathophysiology, clinical
features
Rationale: Illness scripts are cognitive schemas that clinicians
develop with experience, linking risk factors, mechanism, and
presentation.
6. Premature closure is the error of:
a) Ordering too many tests
b) Accepting a diagnosis before verifying all data and
considering alternatives
c) Taking too long to diagnose
d) Involving the patient in decisions
Answer: b) Accepting diagnosis too early
Rationale: Premature closure is a leading cause of diagnostic error.
