DIAGNOSTIC REASONING & CLINICAL DECISION-MAKING
Question 1
A 45-year-old male presents with chest pain. He describes it as "pressure"

and is associated with shortness of breath. Using OLDCARTS, which
component is missing from this history?
A. Onset
B. Location
C. Characteristics
D. Aggravating factors
Answer: D. Aggravating factors
Rationale: The HPI includes onset (2 hours ago while shoveling), location
(chest, radiating to left arm), and characteristics (pressure). However,
aggravating factors (what makes it worse) are not mentioned. OLDCARTS
includes: Onset, Location, Duration, Characteristics, Aggravating factors,
Relieving factors, Treatments, and Severity.
