PATHOPHYSIOLOGY FINAL EXAM
PREP QUESTIONS AND ANSWERS
1. A patient with chronic hypertension exhibits an increase in the size of the left ventricular
myocardial cells. This cellular adaptation is best described as:
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Hypertrophy
Answer: D
Conceptual Explanation: Hypertrophy is an increase in the size of cells in response to
mechanical stimuli like hypertension, whereas hyperplasia is an increase in the number of
cells.
2. Which of the following processes is a programmed cell death characterized by the absence
of inflammation?
A. Necrosis
B. Autophagy
C. Apoptosis
,D. Infarction
Answer: C
Conceptual Explanation: Apoptosis is programmed cell death that occurs without eliciting
an inflammatory response, unlike necrosis which involves cell bursting and inflammation.
3. During an inflammatory response, which mediator is primarily responsible for increasing
capillary permeability and vasodilation?
A. Interleukin-10
B. C-reactive protein
C. Interferon
D. Histamine
Answer: D
Conceptual Explanation: Histamine is released by mast cells and is a potent vasodilator
that increases vascular permeability during the early stages of inflammation.
4. A client is diagnosed with a Type I Hypersensitivity reaction. Which antibody isotype is
predominantly involved in this process?
A. IgG
B. IgM
C. IgA
D. IgE
, Answer: D
Conceptual Explanation: Type I Hypersensitivity is IgE-mediated, involving the binding of
allergens to IgE on mast cells and basophils.
5. What is the primary pathophysiology behind the development of Type 1 Diabetes Mellitus?
A. Insulin resistance in peripheral tissues
B. Downregulation of insulin receptors
C. Excessive secretion of glucagon
D. Autoimmune destruction of pancreatic beta cells
Answer: D
Conceptual Explanation: Type 1 Diabetes results from T-cell mediated autoimmune
destruction of the beta cells in the pancreas, leading to absolute insulin deficiency.
6. In the context of the TNM staging system for cancer, what does the ‘N’ represent?
A. Neoplasm grade
B. Involvement of regional lymph nodes
C. Number of primary tumors
D. Necrotic center size
Answer: B
