NR 507 Week 1-4 Midterm Exam: 100 Practice
Questions with Rationales Covering Cellular
Adaptation, Immunology, Hematology,
Endocrinology, Genetics, and Fluid/Electrolyte
Disorders for Advanced Pathophysiology
Sample NR 507 Week 1-4 Midterm
Questions & Rationales
1. Cellular Adaptation: Hypertrophy
• Question: A patient with chronic
hypertension has an enlarged heart. This
increase in muscle mass is primarily due to
which cellular adaptation?
• A) Hyperplasia
• B) Metaplasia
• C) Hypertrophy
• D) Dysplasia
, • Correct ☑VERIFIED ANSWERS: C)
Hypertrophy
• Rationale: Hypertrophy is an increase in the
size of cells, leading to an enlarged organ.
Cardiac muscle cells are terminally
differentiated and cannot divide
(hyperplasia). They adapt to an increased
workload, like chronic pressure overload
from hypertension, through hypertrophy .
2. Cellular Injury: Point of No Return
• Question: The irreversible point in cellular
injury where cell death is inevitable, even if
the stressor is removed, is known as the:
• A) Point of no return
• B) Cellular apoptosis threshold
• C) Necrotic point
• D) Ischemic threshold
, • Correct ☑VERIFIED ANSWERS: A) Point of
no return
• Rationale: This concept is where
mitochondrial damage becomes so severe
that ATP production ceases entirely. Once
this point is reached, cell death is inevitable
regardless of intervention .
3. Cell Death: Apoptosis
• Question: Which of the following is a
characteristic feature of apoptosis?
• A) Elicits a significant inflammatory
response
• B) Results in cellular swelling and rupture
• C) Involves organized cell shrinkage and
fragmentation
• D) Affects large groups of contiguous cells
, • Correct ☑VERIFIED ANSWERS: C) Involves
organized cell shrinkage and fragmentation
• Rationale: Apoptosis is programmed cell
death characterized by organized cell
shrinkage and fragmentation into apoptotic
bodies. Unlike necrosis, it does not typically
trigger an inflammatory response .
4. Neoplasia: Carcinoma In Situ
• Question: Carcinoma in situ (CIS) refers to:
• A) Malignant cells that have metastasized to
distant sites
• B) Cells that have invaded immediate
surrounding tissue
• C) Cells that remain localized in the
epithelial layer without breaching the
basement membrane
