, SECTION 1: CLINICAL HISTORY & SYMPTOM ANALYSIS
Q1. A 58-year-old man presents with intermittent substernal pressure that radiates to the left jaw and is provoked by climbing
two flights of stairs. The discomfort resolves within three minutes of rest. He denies associated diaphoresis or nausea.
Which element of the history most strongly supports a diagnosis of stable angina rather than an acute coronary syndrome?
A. Substernal location of the pressure
B. Age greater than 55 years
C. Resolution of symptoms with rest within minutes
D. Radiation of pain to the jaw
Correct Answer: C
Rationale:
Symptoms that are reproducibly provoked by exertion and promptly relieved by rest are the hallmark of stable angina. Radiation, location,
and age increase pretest probability of coronary disease but do not distinguish stable from unstable presentations.
Q2. A 42-year-old woman reports six weeks of progressive dyspnea on exertion, orthopnea requiring three pillows, and
occasional paroxysmal nocturnal dyspnea. She has a remote history of rheumatic fever. Which historical feature is most
useful in differentiating left-sided from right-sided heart failure in this patient?
A. Orthopnea and paroxysmal nocturnal dyspnea
B. Duration of symptoms greater than four weeks
C. History of rheumatic fever
D. Absence of lower-extremity edema
Correct Answer: A
Rationale:
Orthopnea and paroxysmal nocturnal dyspnea reflect elevated left-sided filling pressures and pulmonary congestion. Right-sided failure
more typically produces peripheral edema and hepatic congestion. Rheumatic history raises the possibility of valvular disease but does not
localize the failure.
Q3. A 29-year-old previously healthy man describes three days of fever, severe headache, photophobia, and neck stiffness. He
recently returned from a camping trip in the northeastern United States. Which additional historical detail would most
increase suspicion for Lyme meningitis rather than viral meningitis?
A. Fever higher than 39 °C
B. Presence of a target-shaped rash two weeks earlier
C. Absence of vomiting
D. Duration of symptoms longer than 48 hours
Correct Answer: B
Rationale:
An erythema migrans rash is highly suggestive of early disseminated Lyme disease and markedly raises the pretest probability of Lyme
meningitis in the appropriate geographic setting. Viral meningitis is far more common overall, but the rash is a key discriminating feature.

, SECTION 1: CLINICAL HISTORY & SYMPTOM ANALYSIS
Q4. A 67-year-old woman with longstanding type 2 diabetes reports new onset of postprandial epigastric burning that is partially
relieved by antacids. She denies weight loss or dysphagia. Which aspect of the history most strongly argues against a
simple peptic ulcer and warrants earlier endoscopic evaluation?
A. Age greater than 60 years with new-onset dyspepsia
B. Longstanding diabetes mellitus
C. Partial relief with antacids
D. Postprandial timing of symptoms
Correct Answer: A
Rationale:
New-onset dyspepsia in patients older than 60 is considered an alarm feature that increases the likelihood of malignancy or other serious
pathology and justifies prompt endoscopy rather than empiric therapy alone.
Q5. A 35-year-old woman presents with recurrent episodes of abrupt-onset palpitations lasting 10–20 minutes, accompanied by
lightheadedness but no syncope. Episodes terminate spontaneously. She has no known structural heart disease. Which
historical detail most helps distinguish atrioventricular nodal reentrant tachycardia from sinus tachycardia?
A. Abrupt onset and offset of symptoms
B. Duration of episodes under 30 minutes
C. Absence of syncope
D. Presence of lightheadedness
Correct Answer: A
Rationale:
Paroxysmal supraventricular tachycardias such as AVNRT characteristically start and stop abruptly. Sinus tachycardia accelerates and
decelerates more gradually in response to physiologic demand.
Q6. A 51-year-old man with a 30-pack-year smoking history complains of a persistent dry cough for four months and
unintentional weight loss of 8 kg. He denies hemoptysis or night sweats. Which historical element most elevates concern for
primary lung cancer rather than chronic bronchitis?
A. Duration of cough longer than three months
B. Current age between 50 and 55 years
C. Absence of productive sputum
D. Significant unintentional weight loss
Correct Answer: D
Rationale:
Unintentional weight loss is a classic constitutional symptom associated with malignancy. While chronic cough in a smoker is common with
COPD, progressive weight loss substantially raises the pretest probability of lung cancer.
