BARKLEY 3P EXAM QUESTIONS AND ANSWERS 200
HIGH-YIELD EXAM QUESTIONS WITH DETAILED
RATIONALES
1. A 65-year-old male presents with sudden onset of severe, tearing
chest pain that radiates to his back. His blood pressure is 190/110
mmHg in the right arm and 160/90 mmHg in the left arm. What is the
most likely diagnosis?
A) Acute myocardial infarction
B) Pulmonary embolism
C) Aortic dissection
D) Pericarditis
Correct Answer: C) Aortic dissection
Rationale: Aortic dissection classically presents with acute, severe
tearing chest pain radiating to the back, often accompanied by a
significant blood pressure differential between arms (>20 mmHg).
2. Which of the following is NOT part of Virchow's triad?
A) Hypercoagulability
B) Endothelial cell damage
C) Sympathetic tone
D) Turbulent blood flow
Correct Answer: C) Sympathetic tone
Rationale: Virchow's triad consists of hypercoagulability, endothelial
damage, and circulatory stasis (turbulent blood flow). Sympathetic tone
is not a component.
,3. A patient with heart failure has an ejection fraction of 35%. Which
compensatory mechanism initially maintains cardiac output but
eventually becomes maladaptive?
A) Natriuretic peptide release
B) Activation of the renin-angiotensin-aldosterone system (RAAS)
C) Increased vagal tone
D) Decreased afterload
Correct Answer: B) Activation of the renin-angiotensin-aldosterone
system (RAAS)
Rationale: RAAS activation increases preload and afterload via sodium
and water retention and vasoconstriction. While initially compensatory,
chronic activation leads to ventricular remodeling and worsening heart
failure.
4. A 55-year-old male with a 30-pack-year smoking history presents
with dyspnea on exertion and chronic cough. Spirometry shows
FEV1/FVC = 65% post-bronchodilator. Which pathophysiologic
mechanism best explains his airflow obstruction?
A) Airway hyperresponsiveness to allergens
B) Loss of elastic recoil and small airway collapse
C) Thickened basement membrane and eosinophilic inflammation
D) Restrictive lung disease from interstitial fibrosis
Correct Answer: B) Loss of elastic recoil and small airway collapse
Rationale: An FEV1/FVC < 70% post-bronchodilator indicates COPD. The
primary mechanisms include loss of elastic recoil (emphysema) and
small airway fibrosis (chronic bronchitis), leading to air trapping.
5. Which of the following is the most sensitive and specific diagnostic
test for myocardial infarction?
A) Creatine kinase-MB (CK-MB)
,B) Troponin I
C) Myoglobin
D) Lactate dehydrogenase (LDH)
Correct Answer: B) Troponin I
Rationale: Cardiac troponins (I and T) are the most sensitive and specific
biomarkers for myocardial injury. They rise within 3-4 hours and remain
elevated for 7-10 days.
6. A patient experiences a sudden onset of pain in the lower leg. The
area is erythematous and warm to the touch but not swollen. Which
measure is NOT a correct form of treatment for this condition?
A) Elevating the leg
B) Applying warm compresses
C) Prescribing NSAIDs
D) Ordering bed rest
Correct Answer: D) Ordering bed rest
Rationale: The presentation suggests superficial thrombophlebitis.
Treatment includes elevation, warm compresses, and NSAIDs. Bed rest
is a standard treatment for deep vein thrombosis, not superficial
thrombophlebitis.
7. A patient with cirrhosis develops ascites and esophageal varices.
Which hemodynamic abnormality is the primary driver of these
complications?
A) Increased systemic vascular resistance
B) Portal hypertension
C) Decreased cardiac output
D) Renal artery vasodilation
Correct Answer: B) Portal hypertension
Rationale: Portal hypertension increases hydrostatic pressure in the
, splanchnic circulation, leading to ascites and the development of
collateral vessels (esophageal varices).
8. A 45-year-old woman presents with fatigue, weight gain, cold
intolerance, and constipation. TSH is 12.5 mIU/mL, free T4 is 0.6
ng/dL. Which pathophysiologic process is most likely?
A) Central hypothyroidism from pituitary failure
B) Primary hypothyroidism with elevated TSH and low T4
C) Euthyroid sick syndrome
D) Subclinical hyperthyroidism
Correct Answer: B) Primary hypothyroidism with elevated TSH and
low T4
Rationale: Elevated TSH with low free T4 indicates primary
hypothyroidism (thyroid gland failure). Central hypothyroidism would
show low or inappropriately normal TSH.
9. Which of the following is the most common clinical manifestation of
osteoporosis?
A) Bone deformity
B) Bone pain
C) Pathologic fracture
D) Fat embolism
Correct Answer: C) Pathologic fracture
Rationale: Osteoporosis is a chronic, progressive, systemic metabolic
bone disease characterized by low bone mass and deterioration of bone
tissue. It is usually not apparent until after a fracture occurs.
10. A patient with type 1 diabetes mellitus presents with fruity breath
odor, Kussmaul respirations, and confusion. Which condition is most
likely?
