Section 1: Advanced Pathophysiology — Questions 1–35
1.
A 58-year-old male presents with progressive dyspnea on exertion, orthopnea, and
bilateral lower extremity edema. Exam reveals JVD, an S3 gallop, and bibasilar crackles.
BNP is 850 pg/mL. Which pathophysiologic mechanism best explains the S3 gallop?
A. Decreased ventricular compliance with atrial contraction against a stiff ventricle
B. Rapid ventricular filling in early diastole into a dilated ventricle
C. Mitral valve regurgitation during systole
D. Aortic stenosis during systole
Correct Answer: B
Rationale: S3 represents rapid early diastolic filling into a dilated ventricle, commonly
seen in volume overload and heart failure. S4 occurs with a stiff ventricle.
High-Yield Takeaway: S3 = volume overload; S4 = stiff ventricle.
2.
A patient with heart failure has a BNP of 850 pg/mL. What does this indicate?
A. Normal cardiac function
B. Volume overload and heart failure
C. Pulmonary embolism
D. COPD exacerbation
,Correct Answer: B
Rationale: BNP >400 pg/mL strongly supports heart failure with volume overload.
High-Yield Takeaway: BNP >400 = heart failure.
3.
The compensatory mechanism in early congestive heart failure involves:
A. Decreased preload
B. Increased sympathetic tone
C. Decreased afterload
D. Reduced renin release
Correct Answer: B
Rationale: Early heart failure triggers increased sympathetic tone to maintain cardiac
output, though this eventually becomes maladaptive.
High-Yield Takeaway: Early HF = increased sympathetic tone.
4.
In heart failure, activation of the renin-angiotensin system leads to:
A. Sodium excretion and decreased preload
B. Vasodilation and reduced afterload
C. Sodium retention and increased blood volume
D. Reduced aldosterone secretion
Correct Answer: C
Rationale: RAAS activation in heart failure causes sodium and water retention,
increasing blood volume and preload, which worsens heart failure.
High-Yield Takeaway: HF = RAAS activation = sodium retention.
5.
,Which disease is characterized by demyelination of the central nervous system?
A. Guillain-Barré syndrome
B. Multiple sclerosis
C. Myasthenia gravis
D. Amyotrophic lateral sclerosis
Correct Answer: B
Rationale: Multiple sclerosis is characterized by immune-mediated demyelination of the
CNS.
High-Yield Takeaway: MS = CNS demyelination.
6.
In Type 1 Diabetes Mellitus, the primary defect is:
A. Peripheral insulin resistance
B. Autoimmune destruction of beta cells
C. Increased hepatic gluconeogenesis
D. Overproduction of glucagon
Correct Answer: B
Rationale: Type 1 diabetes is caused by autoimmune destruction of pancreatic beta
cells, leading to absolute insulin deficiency.
High-Yield Takeaway: Type 1 DM = autoimmune beta cell destruction.
7.
Which of the following best explains the pathophysiology of Graves' disease?
A. Destruction of thyroid follicles
B. Antibodies that stimulate TSH receptors
C. Pituitary adenoma producing TSH
D. Iodine deficiency
, Correct Answer: B
Rationale: Graves' disease is caused by TSH receptor antibodies that stimulate the
thyroid gland, leading to hyperthyroidism.
High-Yield Takeaway: Graves' = TSH receptor antibodies.
8.
A patient with Addison's disease is most likely to have which electrolyte imbalance?
A. Hypernatremia and hypokalemia
B. Hyponatremia and hyperkalemia
C. Hypernatremia and hyperkalemia
D. Hyponatremia and hypocalcemia
Correct Answer: B
Rationale: Addison's disease (adrenal insufficiency) causes hyponatremia and
hyperkalemia due to aldosterone deficiency.
High-Yield Takeaway: Addison's = hyponatremia + hyperkalemia.
9.
The main cause of anemia in chronic kidney disease is:
A. Iron deficiency
B. Bone marrow suppression
C. Decreased erythropoietin production
D. Folate deficiency
Correct Answer: C
Rationale: CKD causes anemia primarily due to decreased erythropoietin production by
damaged kidneys.
High-Yield Takeaway: CKD anemia = decreased erythropoietin.
