Exam Overview
This academic exam resource gives Nursing School a focused 100-question practice set for Advanced
Pathophysiology WEEK - Chamberlain University And Correct Plus. The material is written to
support careful review, practical reasoning, and steady preparation without promotional claims or
repeated title wording. Questions use clear professional language, credible answer choices, and
concise rationales that help students understand why one option is best. The document provides
high-quality academic material for independent revision, classroom reinforcement, and identifying
knowledge gaps before assessments. Students should pair it with course notes, textbooks, instructor
guidance, and current academic standards for the strongest preparation. Each item supports.
Question 1: Which mediator is most directly responsible for causing vasodilation during
acute inflammation?
A. Erythropoietin
B. Albumin
C. Insulin
D. Histamine
Answer: D
Rationale: Histamine is a key early inflammatory mediator that promotes vasodilation and increased
vascular permeability.
Question 2: A smoker develops thickened airway epithelium in response to chronic
irritation. What adaptation is this?
A. Atrophy
B. Hypertrophy
C. Dysplasia
D. Metaplasia
Answer: D
Rationale: Metaplasia is a reversible change in which one mature cell type is replaced by another
better suited to the stress.
Question 3: Which finding is most consistent with tissue hypoxia at the cellular level?
A. Increased ATP production
B. Enhanced mitochondrial oxygen use
C. Decreased lactic acid formation
D. Failure of the sodium-potassium pump
Answer: D
Rationale: Low oxygen impairs ATP generation, leading to failure of ion pumps and cellular
swelling.

Question 4: Which term describes an increase in the number of cells in a tissue in response
to a persistent stimulus such as hormonal signaling?
A. Dysplasia
B. Metaplasia
C. Hypertrophy
D. Hyperplasia
Answer: D
Rationale: Hyperplasia is a proliferative response that increases cell number. Hypertrophy enlarges
existing cells, while metaplasia is replacement of one mature cell type with another and dysplasia
refers to disordered growth.
Question 5: During acute inflammation, which mediator is most directly linked to pain by
sensitizing peripheral nerve endings?
A. Histamine
B. Erythropoietin
C. Albumin
D. Prostaglandins
Answer: D
Rationale: Prostaglandins sensitize nociceptors and contribute to inflammatory pain. Histamine is
more strongly associated with vasodilation and increased vascular permeability, not primary pain
sensitization.
Question 6: A client has metabolic acidosis. Which respiratory response is expected?
A. Hypoventilation to retain carbon dioxide
B. Apnea to conserve oxygen
C. Bradycardia to retain bicarbonate
D. Hyperventilation to blow off carbon dioxide
Answer: D
Rationale: The lungs compensate for metabolic acidosis by increasing ventilation and reducing CO2.
Question 7: A patient with left-sided heart failure reports orthopnea and crackles. What is
the primary cause of these findings?
A. Excessive erythrocyte production
B. Decreased systemic venous return only
C. Hyperventilation from anxiety alone
D. Pulmonary congestion from backward blood flow
