COMPREHENSIVE PATHOPHYSIOLOGY FINAL EXAM REVIEW: 200 HIGH-
YIELD EXAM QUESTIONS COMPLETE WITH VERIFIED ANSWERS
1. Which of the following best describes the primary mechanism of cell injury in
hypoxia?
A. Increased ATP production
B. Failure of the sodium-potassium pump
C. Enhanced oxidative phosphorylation
D. Rapid cellular hypertrophy
Correct Answer: B
Rationale: Hypoxia leads to decreased ATP production, causing the sodium-
potassium pump to fail. This results in cellular swelling, influx of calcium, and
ultimately cell death.
2. A patient presents with a fever, leukocytosis, and localized pain. Which of the
following is the most likely diagnosis?
A. Degenerative joint disease
B. Acute inflammation
C. Nutritional deficiency
D. Genetic mutation
Correct Answer: B
Rationale: Fever, leukocytosis, and localized pain are classic cardinal signs of acute
inflammation, which is the body's response to injury or infection.
3. Which of the following is a characteristic of benign neoplasms?
A. Infiltrative growth
B. High mitotic rate
C. Encapsulated and well-circumscribed
D. Frequent metastasis
Correct Answer: C
,Rationale: Benign tumors are typically encapsulated, grow slowly, and do not
metastasize, unlike malignant tumors.
4. A 45-year-old male has a blood pressure of 160/100 mmHg. This is classified
as:
A. Normal
B. Prehypertension
C. Stage 1 Hypertension
D. Stage 2 Hypertension
Correct Answer: D
Rationale: A blood pressure of 160/100 mmHg falls into Stage 2 Hypertension
according to ACC/AHA guidelines (systolic ≥160 or diastolic ≥100).
5. What is the most common cause of iron deficiency anemia?
A. Chronic blood loss
B. Hemolysis
C. Bone marrow failure
D. Vitamin B12 deficiency
Correct Answer: A
Rationale: Chronic blood loss, often from gastrointestinal bleeding or
menstruation, is the most common cause of iron deficiency anemia.
6. Which of the following is a risk factor for atherosclerosis?
A. Low LDL cholesterol
B. High HDL cholesterol
C. Smoking
D. Regular exercise
Correct Answer: C
Rationale: Smoking is a major modifiable risk factor for atherosclerosis, as it
damages the endothelial lining of arteries.
7. A patient with type 1 diabetes mellitus is most likely to present with:
A. Obesity
B. Insulin resistance
C. Autoimmune destruction of beta cells
,D. Hyperinsulinism
Correct Answer: C
Rationale: Type 1 diabetes is characterized by the autoimmune destruction of
pancreatic beta cells, leading to absolute insulin deficiency.
8. Which of the following is a complication of chronic hypertension?
A. Left ventricular hypertrophy
B. Hypotension
C. Aortic dissection
D. Both A and C
Correct Answer: D
Rationale: Chronic hypertension leads to left ventricular hypertrophy and
increases the risk of aortic dissection.
9. The most common cause of community-acquired pneumonia is:
A. Staphylococcus aureus
B. Streptococcus pneumoniae
C. Pseudomonas aeruginosa
D. Klebsiella pneumoniae
Correct Answer: B
Rationale: Streptococcus pneumoniae is the most frequent cause of community-
acquired pneumonia.
10. Which of the following describes apoptosis?
A. Programmed cell death
B. Inflammatory cell death
C. Ischemic necrosis
D. Coagulative necrosis
Correct Answer: A
Rationale: Apoptosis is a form of programmed cell death that does not trigger an
inflammatory response.
11. A 60-year-old smoker presents with a chronic cough and weight loss. Which
of the following is the most likely diagnosis?
A. Asthma
, B. Lung cancer
C. Tuberculosis
D. Bronchitis
Correct Answer: B
Rationale: Chronic cough and weight loss in a smoker are red flags for lung cancer.
12. Which of the following is a function of the kidneys?
A. Regulation of blood pressure
B. Production of bile
C. Storage of glycogen
D. Synthesis of albumin
Correct Answer: A
Rationale: The kidneys regulate blood pressure through the renin-angiotensin-
aldosterone system.
13. What is the primary cause of peptic ulcer disease?
A. Stress
B. Helicobacter pylori infection
C. Spicy food
D. Alcohol consumption
Correct Answer: B
Rationale: Helicobacter pylori infection is the leading cause of peptic ulcer
disease.
14. Which of the following is a sign of dehydration?
A. Bradycardia
B. Hypertension
C. Poor skin turgor
D. Polyuria
Correct Answer: C
Rationale: Poor skin turgor is a classic sign of dehydration due to loss of interstitial
fluid.
15. A patient with cirrhosis is at risk for which of the following?
A. Bleeding tendencies
