PATHOPHYSIOLOGY EXAM 3 REVIEW WITH COMPLETE
REAL EXAM QUESTIONS AND CORRECT VERIFIED
ANSWERS/ ALREADY GRADE A+ (BRAND NEW!!)
1. A patient with chronic hypertension develops left
ventricular hypertrophy. This is an example of which type of
cellular adaptation?
A. Hyperplasia
B. Metaplasia
C. Hypertrophy
D. Dysplasia
Correct Answer: C
Rationale: Hypertrophy is an increase in cell size due to
increased workload (pressure overload in hypertension).
1
,Cardiomyocytes do not divide significantly (hyperplasia is
minimal).
2. In heart failure with reduced ejection fraction (HFrEF), the
initial compensatory mechanism is:
A. Peripheral vasodilation
B. Activation of the renin-angiotensin-aldosterone system (RAAS)
and sympathetic nervous system
C. Decreased preload
D. Atrial natriuretic peptide (ANP) release to increase blood
volume
Correct Answer: B
Rationale: Reduced cardiac output → decreased renal perfusion
→ RAAS activation → vasoconstriction and sodium/water
retention. Sympathetic activation increases HR and contractility
(initially compensatory, then maladaptive).

,3. A patient presents with chest pain at rest that resolves with
nitroglycerin. The most likely diagnosis is:
A. Unstable angina
B. NSTEMI
C. STEMI
D. Stable angina
Correct Answer: A
Rationale: Unstable angina occurs at rest, is prolonged, or is
increasing in frequency. It is due to plaque rupture/thrombus
without persistent elevation of cardiac enzymes. Stable angina
occurs with exertion and resolves with rest.
4. Which of the following is the most specific cardiac
biomarker for myocardial infarction?
A. CK-MB
3
, B. Myoglobin
C. Troponin I or T
D. LDH
Correct Answer: C
Rationale: Cardiac troponins (I and T) are highly sensitive and
specific for myocardial necrosis. They rise 3-4 hours after MI and
remain elevated for 7-14 days.
5. A patient with aortic stenosis develops syncope on
exertion. The mechanism is:
A. Fixed obstruction → inability to increase cardiac output during
exercise → decreased cerebral perfusion
B. Bradycardia
C. Hypovolemia
D. Pulmonary hypertension
