Advanced Pathophysiology Practice Test questions with
answers
1. In a clinical scenario where a patient presents with an enlarged prostate
due to excessive cell proliferation, what type of cellular adaptation is likely
occurring?
Dysplasia
Apoptosis
Pathologic hyperplasia
Hypertrophy
2. In a clinical scenario where a patient has experienced significant
oxidative stress, which type of cell death is likely to occur, and why?
Necrosis, because it is the only type of cell death that occurs under
stress.
Autophagy, because it helps in recycling cellular components.
Apoptosis, because it is a controlled process that eliminates
damaged cells without causing inflammation.
Cellular hypertrophy, because it compensates for damage.
3. In a clinical scenario where a patient exhibits dysplastic cells in a biopsy,
what potential outcome should the healthcare provider monitor for?
Increased cell size
Normal cellular function
Development of cancer
Decreased cell number
1/53
,4. What is a characteristic feature of wet gangrene?
It only affects the skin.
Infection and inflammation are present in wet gangrene.
It is characterized by the absence of bacteria.
It is caused solely by venous stasis.
5. Decreased oxygen (hypoxia) impairs oxidative phosphorylation, which
results in a decreased ___ production
ADP
ATP
NADH
Mitochondria
6. Describe how oxidative stress contributes to cellular injury.
Oxidative stress is a form of cellular adaptation that protects against
injury.
Oxidative stress enhances cellular repair mechanisms and promotes
health.
Oxidative stress results from an imbalance between free radicals
and antioxidants, leading to damage of cellular components.
Oxidative stress is solely caused by external toxins and has no internal
sources.
7. Describe the significance of dysplasia in relation to cellular health
and potential disease progression.
Dysplasia indicates abnormal cell growth that may lead to cancer.
2/53
, Dysplasia has no clinical significance.
Dysplasia is a normal adaptive response to stress.
Dysplasia is a type of cell injury that is always reversible.
8. What term describes the abnormal development or growth of cells that can
indicate a precancerous condition?
Hyperplasia
Dysplasia
Apoptosis
Hypertrophy
9. What is the primary consequence of impaired function of the Na-K
membrane pump in myocardial cells?
Extracellular potassium will decrease
All of the above
Cell volume will decrease
Intracellular sodium will increase
10. Describe how free radicals can contribute to the development of cancer.
Free radicals have no effect on cellular health.
Free radicals can cause DNA damage, leading to mutations that
may result in cancer.
Free radicals enhance the immune response against cancer cells.
Free radicals only affect the nervous system.
3/53
, 11. What role does glutathione play in dopamine synthesis?
It increases the levels of oxidative stress.
It prevents free radical production.
It enhances DNA synthesis.
It facilitates the entry of dopamine into the brain.
12. In a clinical study, researchers find that patients with higher levels of
oxidative stress markers have an increased incidence of cancer. What
might be a potential intervention to reduce cancer risk in these patients?
Sedentary lifestyle
Antioxidant therapy
Increased exposure to UV light
High-fat diet
13. If the population of the Midwestern city increased to 1,200,000 by the end
of 1992 and the number of new AIDS cases remained the same, what would
be the new incidence rate per 100,000 population?
25
21
30
20.83
14. What is the primary consequence of reperfusion injury?
A burst of free radical production from neutrophils.
Increased blood pressure causing vessel rupture.
