How to Use This Study Bundle
This comprehensive NR-507 Advanced Pathophysiology Week 8 Final Exam preparation bundle
contains over 1,100 multiple-choice questions covering every major content domain tested on your final
examination. Each question mirrors the NCLEX-style clinical vignette format used in graduate-level
nursing education and aligns with the Chamberlain University NR-507 course objectives.
STUDY STRATEGY
1. Work through each section systematically, covering the answer and rationale first.
2. For each incorrect answer, review the full rationale and the underlying pathophysiology concept.
3. Focus on mechanism — understanding WHY an answer is correct, not just WHAT the answer is.
4. Revisit sections where you score below 80% and repeat until mastery is achieved.
5. Pay special attention to acid-base, shock, and cardiovascular pathophysiology — these are high-
yield topics on the NR-507 final.

CARDIOVASCULAR PATHOPHYSIOLOGY
This section contains 152 questions covering Cardiovascular Pathophysiology. Work through each
question carefully before reviewing the answer and rationale.
Question 1. A 68-year-old male presents with crushing chest pain radiating to the left arm, diaphoresis,
and nausea. ECG shows ST-segment elevation in leads II, III, and aVF. Which coronary artery is most
likely occluded?
A. Left anterior descending (LAD) artery
B. Left circumflex artery
C. Right coronary artery (RCA)
D. Left main coronary artery
ANSWER: C. Right coronary artery (RCA)
Rationale: ST elevation in leads II, III, and aVF indicates inferior MI, which is most commonly caused
by RCA occlusion. The RCA supplies the inferior wall of the left ventricle and right ventricle in most
patients.
Question 2. Which pathophysiological mechanism is primarily responsible for the systolic dysfunction
seen in dilated cardiomyopathy?
A. Concentric hypertrophy from pressure overload
B. Loss of contractile myocytes replaced by fibrosis
C. Pericardial constriction limiting filling
D. Valvular regurgitation causing volume overload
ANSWER: B. Loss of contractile myocytes replaced by fibrosis
Rationale: Dilated cardiomyopathy involves myocyte loss and replacement fibrosis, resulting in
decreased contractility and systolic dysfunction. The ventricles dilate to compensate but ejection
fraction falls progressively.
Question 3. A patient with chronic heart failure develops orthopnea and paroxysmal nocturnal
dyspnea. What is the primary mechanism for these symptoms?
A. Decreased cardiac output stimulating central chemoreceptors
B. Redistribution of fluid from the periphery to the pulmonary circulation in the supine position
C. Nocturnal hypoxemia triggering bronchospasm
D. Right ventricular failure causing hepatic congestion
ANSWER: B. Redistribution of fluid from the periphery to the pulmonary circulation in the
supine position
Rationale: When a patient with HF lies supine, venous return increases as peripheral edema fluid
redistributes centrally. The failing left ventricle cannot handle the increased preload, raising pulmonary
capillary wedge pressure and causing pulmonary edema.
Question 4. Which of the following best describes the Frank-Starling mechanism and its role in heart
failure compensation?
A. Increased heart rate compensates for decreased stroke volume
B. Ventricular hypertrophy reduces wall stress by increasing wall thickness
C. Increased preload stretches myocardial fibers, enhancing contractility up to a limit
D. RAAS activation causes vasoconstriction to maintain perfusion pressure
ANSWER: C. Increased preload stretches myocardial fibers, enhancing contractility up to a limit

, NR-507 Advanced Pathophysiology | Week 8 Final Exam Preparation Bundle
Rationale: The Frank-Starling mechanism states that increased ventricular filling (preload) increases
myocardial fiber stretch, optimizing actin-myosin overlap and thereby increasing stroke volume. In
severe HF, the ventricle operates on the flat part of this curve and loses this compensatory ability.
Question 5. A 55-year-old with longstanding hypertension develops left ventricular hypertrophy with
preserved ejection fraction. This best represents:
A. Dilated cardiomyopathy
B. Diastolic dysfunction (HFpEF)
C. Systolic dysfunction (HFrEF)
D. Hypertrophic obstructive cardiomyopathy
ANSWER: B. Diastolic dysfunction (HFpEF)
Rationale: Chronic pressure overload from hypertension causes concentric LVH, which impairs
ventricular relaxation and compliance. The EF is preserved (≥50%) but diastolic filling is impaired,
leading to HFpEF.
Question 6. Which marker is most specific for myocardial cell necrosis and rises approximately 4–6
hours after STEMI onset?
A. CK-MB
B. Myoglobin
C. Troponin I or T
D. LDH
ANSWER: C. Troponin I or T
Rationale: Cardiac troponins I and T are highly specific for myocardial necrosis. They begin to rise 4–6
hours after injury, peak at 12–24 hours, and remain elevated for 7–14 days, making them the gold
standard biomarker for MI diagnosis.
Question 7. Aortic stenosis produces a pressure gradient between the left ventricle and the aorta. The
primary compensatory mechanism is:
A. Eccentric hypertrophy to maintain stroke volume
B. Concentric hypertrophy to maintain wall stress and EF
C. Increased heart rate to compensate for decreased stroke volume
D. Activation of BNP to reduce preload
ANSWER: B. Concentric hypertrophy to maintain wall stress and EF
Rationale: Chronic pressure overload from aortic stenosis causes concentric LVH. Per the Law of
Laplace (wall stress = P × r / 2h), increasing wall thickness (h) normalizes wall stress despite elevated
intraventricular pressure.
Question 8. A patient presents with jugular venous distension, peripheral edema, and hepatomegaly
without significant dyspnea. These signs are most consistent with:
A. Left-sided heart failure
B. Right-sided heart failure
C. Cardiac tamponade
D. Pulmonary embolism
ANSWER: B. Right-sided heart failure
Rationale: Right heart failure leads to venous congestion of the systemic circulation, causing JVD,
peripheral pitting edema, and congestive hepatomegaly. Pulmonary congestion (dyspnea) is a feature
of left heart failure.
Question 9. Which of the following is the most common cause of right-sided heart failure?
