[SECTION 1: Assessment & Diagnosis — Questions 1-40]
Q1: A 52-year-old male presents with "crushing" substernal chest pain radiating to his left arm.
He is diaphoretic and nauseous. What is the most appropriate initial diagnostic test?
A. Exercise stress test
B. Chest X-ray
C. Computed Tomography (CT) Angiography of the chest
D. Electrocardiogram (ECG)
Correct Answer: D
Rationale: The patient's presentation is classic for Acute Coronary Syndrome (ACS). The ECG is
the immediate first-line diagnostic test to identify ST-elevation myocardial infarction (STEMI),
which dictates immediate reperfusion therapy (PCI). Exercise stress testing is contraindicated in
an acute setting; CT Angiography is used for low-risk patients with negative enzymes and ECGs
to rule out pulmonary embolism or aortic dissection. Chest X-ray will not diagnose ischemia.
Q2: A 65-year-old female patient reports difficulty sleeping, low energy, and a loss of interest in
her hobbies for the past two months. She has lost 10 pounds unintentionally. She denies suicidal
ideation. Which screening tool is most appropriate to administer?
A. CAGE questionnaire
B. PHQ-9 (Patient Health Questionnaire-9)
C. Mini-Mental State Examination (MMSE)
D. Geriatric Depression Scale (GDS)
Correct Answer: B
,2
Rationale: The PHQ-9 is a validated tool for screening, diagnosing, monitoring, and measuring
severity of depression in adults. It addresses the nine DSM-5 criteria for depression and fits the
patient's symptoms (sleep disturbance, energy loss, interest loss). CAGE is for alcohol use,
MMSE is for cognitive impairment, and while GDS is specific to older adults, PHQ-9 is the
standard initial screening tool.
Q3: During a cardiac examination, you auscultate the precordium and hear a mid-systolic click
followed by a systolic ejection murmur radiating to the carotids. What is the most likely
diagnosis?
A. Aortic stenosis
B. Mitral regurgitation
C. Mitral valve prolapse
D. Aortic regurgitation
Correct Answer: C
Rationale: A mid-systolic click followed by a late systolic murmur is the classic presentation of
Mitral Valve Prolapse (MVP). Aortic stenosis typically presents with a crescendo-decrescendo
systolic murmur radiating to the carotids, but usually without a click. Mitral regurgitation usually
presents with a holosystolic murmur radiating to the axilla. Aortic regurgitation is a diastolic
murmur.
Q4: A 75-year-old patient is brought to the clinic by his daughter due to memory loss, misplacing
items, and difficulty managing finances. You perform the Mini-Cog (a rapid screening tool for
cognitive impairment). The patient is asked to recall three words five minutes later and
remembers zero. He cannot draw a clock face correctly. What is the appropriate next step?
A. Reassure the daughter that this is normal aging.
B. Order a CT of the head without contrast.
C. Perform a comprehensive laboratory workup to rule out reversible causes.
D. Refer to hospice immediately.
Correct Answer: C
,3
Rationale: The patient is showing signs of cognitive impairment (Mini-Cog score 0/3 on recall
and clock drawing failure). The first step is to identify reversible causes such as depression, B12
deficiency, hypothyroidism, urinary tract infection, or medication side effects through lab
workup. A CT scan may be needed later but labs are first. Hospice is inappropriate for diagnosis,
and this is not "normal aging."
Q5: A 4-year-old child presents with a "barking" cough, stridor, and a low-grade fever.
Symptoms worsened over the last 12 hours. What is the most likely diagnosis?
A. Asthma
B. Bronchiolitis
C. Croup
D. Epiglottitis
Correct Answer: C
Rationale: Croup (Laryngotracheobronchitis) typically presents in children aged 6 months to 3
years with a history of an upper respiratory infection, followed by a barking cough and stridor.
Symptoms often worsen at night. Asthma usually causes wheezing. Bronchiolitis presents in
infants under 2 years with wheezing and respiratory distress. Epiglottitis presents with high
fever, drooling, and a toxic appearance, requiring a "sniffing" position.
Q6: A 45-year-old male presents with sudden onset of severe shortness of breath and pleuritic
chest pain. He has a history of recent knee surgery. His respiratory rate is 28, HR is 110, and
SpO2 is 88% on room air. What is the highest priority diagnostic test?
A. Chest X-ray
B. D-dimer
C. CT Angiogram (CTA) of the chest
D. V/Q scan
Correct Answer: C
Rationale: The patient's presentation (tachycardia, hypoxia, pleuritic pain, recent surgery) is
highly suspicious for a Pulmonary Embolism (PE). CT Angiogram is the test of choice (gold
, 4
standard) for diagnosing PE in a stable patient. D-dimer is used for rule-out (high negative
predictive value) but this patient is high risk; a negative D-dimer wouldn't rule it out. V/Q scan is
an alternative if contrast cannot be used.
Q7: A 60-year-old female presents with a 2-week history of progressive fatigue, weight loss, and
fever. She has enlarged, non-tender lymph nodes in her cervical chain. A CBC shows Hgb 10.2
and WBC 3.5. What is the most appropriate initial diagnostic imaging?
A. PET scan
B. Chest X-ray
C. CT Chest/Abdomen/Pelvis
D. MRI of the neck
Correct Answer: C
Rationale: The patient presents with "B symptoms" (fever, weight loss, night sweats - though not
explicitly stated, symptoms suggest systemic illness), lymphadenopathy, and pancytopenia (Hgb
and WBC low), which is highly suggestive of Lymphoma. A CT scan of the neck, chest,
abdomen, and pelvis is the standard staging and diagnostic imaging modality to assess lymph
node involvement and organomegaly. PET scan is often used subsequently for metabolic activity
and staging, but CT is foundational.
Q8: A 52-year-old male presents for a routine physical. His BMI is 32. His blood pressure is
138/86. His fasting glucose is 118 mg/dL. Which lab test is the priority to rule out impaired
fasting glucose or diabetes?
A. HbA1c
B. 2-hour post-prandial glucose
C. Fasting Insulin
D. Urinalysis for glucose
Correct Answer: A
Rationale: An HbA1c test provides an average of blood glucose over the past 2-3 months and is
the preferred diagnostic test for diabetes (Fasting Glucose
