NSG 530 Exam 1 Study Guide Advanced Pathophysiology
Review
1. In a clinical scenario where a patient has undergone partial hepatectomy,
which cellular adaptation is likely to occur in the liver, and what is its
significance?
Metaplasia, which would change the liver cells into a different cell
type.
Atrophy, which would reduce liver function.
Compensatory physiologic hyperplasia, which is significant for
restoring liver mass and function.
Dysplasia, which may indicate a risk of cancer development.
2. Etiology is defined as the study of which of the following?
Understanding of disease
Stratification of disease
Socioeconomic facts of disease
Cause of disease
3. What is the primary consequence of chronic alcoholism related to fatty liver
development?
Decreased binding of cholesterol, triglycerides, and phospholipids to
apoproteins
Increased production of free fatty acids
Increased conversion of free fatty acids to triglycerides
Decreased oxidation of cholesterol, triglycerides, and phospholipids
,4. Metaplasia is of clinical importance because
It occurs after dysplasia
It indicates areas of continuing cellular injury
It is associated with acute inflammation
It is invariably a precursor to neoplasia
5. 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
6. 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
7. Anaerobic metabolism is a condition of the cell that results in:
lactic acid production, decreased blood pH, and metabolic acidosis.
carbon dioxide production, decreased blood pH, and respiratory
acidosis.
, lactic acid destruction, increased blood pH, and metabolic alkalosis.
carbon dioxide elimination, increased blood pH, and metabolic
alkalosis.
8. Describe how metaplasia can be both a protective mechanism and a
potential risk factor for disease.
Metaplasia can protect tissues from injury by replacing sensitive cell
types with more resilient ones, but it may also predispose to
dysplasia and cancer.
Metaplasia is always harmful and leads to cell death.
Metaplasia has no impact on cellular health and is purely a cosmetic
change.
Metaplasia only occurs in response to genetic mutations.
9. What is the definition of hyperplasia?
A type of cell injury that leads to cell death.
An increase in the number of cells in a tissue or organ.
An increase in cell size without an increase in cell number.
A decrease in the number of cells in a tissue or organ.
10. What term is used to describe a neoplasm that exhibits dysplastic changes
but has not yet invaded surrounding tissues?
Carcinoma in situ
Benign tumor
Metastatic cancer
Malignant tumor
, 11. In a clinical scenario where a patient experiences a myocardial infarction,
what cellular changes would you expect due to ischemia?
Improved cellular function
Increased cellular proliferation
Enhanced ATP synthesis
Cellular injury and potential necrosis
12. In a clinical scenario where a patient experiences ischemia, what would you
expect to happen to intracellular calcium levels in affected cells?
Intracellular calcium levels would remain stable despite ischemia.
Intracellular calcium levels would increase due to loss of calcium
steady state.
Intracellular calcium levels would decrease due to improved calcium
regulation.
Intracellular calcium levels would fluctuate without a clear trend.
13. In a clinical scenario where myocardial cells are subjected to ischemia, what
would you expect to happen to intracellular sodium levels and why?
Intracellular sodium levels would remain unchanged as the Na-K
pump is unaffected.
Intracellular sodium levels would decrease due to increased
potassium influx.
Intracellular sodium levels would increase due to impaired Na-K
pump function during ischemia.
Intracellular sodium levels would decrease as the cells adapt to low
oxygen.
