QUESTIONS AND A CURRENT UPDATED STUDY GUIDE COMPLETE
ACCURATE EXAM
1. A patient presents with progressive fatigue, exertional dyspnea, and
dependent edema. Assessment reveals jugular venous distention, bilateral
crackles, an S3 gallop, and reduced left ventricular ejection fraction. Which
pathophysiologic mechanism best explains the development of pulmonary
congestion in this patient?
A. Increased pulmonary vascular resistance caused by isolated right
ventricular failure
B. Reduced systemic venous pressure causing movement of fluid into the
alveoli
C. Increased left ventricular filling pressure transmitted backward into the
pulmonary circulation
D. Increased lymphatic drainage preventing fluid accumulation in the
pulmonary interstitium
Answer: C
2. A 68-year-old patient with longstanding hypertension develops concentric
left ventricular hypertrophy. The patient eventually develops exertional
dyspnea despite a relatively preserved ejection fraction. Which mechanism
most directly explains the development of symptoms?
A. Impaired ventricular relaxation causing elevated filling pressures

demand

extremities, oliguria, and altered mental status. The cardiac index is
markedly reduced despite adequate intravascular volume. Which type of
shock is most consistent with these findings?
pg. 1
, A. Hypovolemic shock
B. Cardiogenic shock
C. Neurogenic shock
D. Distributive shock
Answer: B
4. A patient with chronic obstructive pulmonary disease has a prolonged
smoking history, barrel-shaped chest, progressive exertional dyspnea, and
diminished breath sounds. Which structural change is most characteristic of
emphysema?

B. Thickening of bronchial smooth muscle from chronic infection
C. Diffuse pulmonary fibrosis with reduced lung compliance
D. Accumulation of pleural fluid compressing the alveoli
Answer: A
5. A patient with severe asthma develops increasing wheezing followed by
markedly diminished breath sounds, fatigue, and rising carbon dioxide
levels. Which interpretation is most appropriate?
A. The patient is improving because wheezing is decreasing
B. The patient has developed isolated metabolic alkalosis
C. The patient has developed respiratory muscle fatigue with worsening
airflow obstruction
D. The patient has developed increased alveolar ventilation from improved
airway caliber
Answer: C
6. A patient develops acute respiratory distress after severe sepsis. The patient
becomes profoundly hypoxemic despite supplemental oxygen, and imaging
demonstrates bilateral diffuse pulmonary infiltrates without evidence of
left-sided heart failure. Which pathophysiologic process is most likely
responsible?
A. Increased pulmonary venous pressure from mitral stenosis
B. Increased alveolar-capillary permeability with noncardiogenic pulmonary
pg. 2
, edema
C. Decreased pulmonary capillary permeability from sympathetic
stimulation
D. Isolated obstruction of the upper airway
Answer: B
7. A patient with long-standing hypertension develops chronic kidney disease.
Laboratory testing demonstrates normocytic anemia despite adequate iron
stores. Which mechanism best explains this anemia?
A. Excessive destruction of erythrocytes by the spleen
B. Increased gastrointestinal blood loss
C. Reduced erythropoietin production by damaged renal tissue
D. Increased hepatic destruction of hemoglobin
Answer: C
8. A patient with nephrotic syndrome has generalized edema,
hypoalbuminemia, and marked proteinuria. Which mechanism primarily
contributes to the edema?
A. Increased plasma oncotic pressure
B. Decreased renal sodium retention
C. Increased lymphatic clearance of interstitial fluid
D. Reduced plasma oncotic pressure caused by urinary protein loss
Answer: D
9. A patient with acute kidney injury develops oliguria after prolonged
hypotension during surgery. Which mechanism is most consistent with
prerenal acute kidney injury?
A. Reduced renal perfusion causing decreased glomerular filtration
B. Immune-mediated destruction of glomerular capillaries
C. Direct tubular toxicity from an aminoglycoside
D. Bilateral ureteral obstruction caused by calculi
Answer: A
10. A patient with chronic kidney disease develops bone pain and laboratory
abnormalities involving calcium, phosphate, and parathyroid hormone.
pg. 3
, Which pathophysiologic mechanism contributes to renal osteodystrophy?
A. Increased renal production of active vitamin D
B. Phosphate retention and impaired activation of vitamin D
C. Persistent hypercalcemia suppressing parathyroid hormone
D. Increased intestinal absorption of calcium caused by renal failure
Answer: B
11. A patient develops severe epigastric pain radiating to the back with
markedly elevated pancreatic enzymes. Which process best explains the
tissue injury associated with acute pancreatitis?
A. Premature activation of pancreatic digestive enzymes within the
pancreas
B. Complete inhibition of pancreatic enzyme secretion
C. Autoimmune destruction of gastric parietal cells
D. Increased bile production without pancreatic inflammation
Answer: A
12. A patient with cirrhosis develops abdominal distention, ascites, and
peripheral edema. Which combination of mechanisms most directly
contributes to these findings?
A. Decreased portal pressure and increased albumin synthesis
B. Increased plasma oncotic pressure and renal sodium loss
C. Portal hypertension, hypoalbuminemia, and sodium-water retention
D. Increased hepatic blood flow and decreased aldosterone activity
Answer: C
13. A patient with advanced cirrhosis becomes confused and develops asterixis.
Which pathophysiologic mechanism most likely contributes to the
neurologic manifestations?
A. Increased cerebral glucose utilization
B. Accumulation of neurotoxic substances such as ammonia
C. Decreased intestinal production of nitrogenous compounds
D. Increased hepatic clearance of ammonia
Answer: B
