WGU D236: Objective Assessment – Pathophysiology
Exam 2025/2026 | Complete Exam Questions with
Detailed Answers| Updated & Graded A+
Adaptive cellular mechanisms function to:
a. treat disease
b. protect cells from injury
c. prevent cellular aging
d. speed up cellular death b. protect cells from injury
Adaptive cellular mechanisms help cells adjust to
environmental changes, thus protecting them from injury
Cellular atrophy involves:
a. an increase in cell size
,b. a decrease in cell size
c. an increase in the number of cells
d. a decrease in the number of cells b. a decrease in the
number of cells.
An individual with damage to the spinal cord may
experience atrophy of which of the following organs?
a. liver
b. brain
c. skeletal muscles
d. skin c. skeletal muscles
,Hypoxic injury results from a lack of oxygen. The most
common cause of this type of cell injury is ischemia, a
decrease in blood flow to the tissue.
A direct result of anaerobic metabolism during hypoxic cell
injury is:
a. increased ATP
b. metabolic acidosis
c. tissue ischemia
d. all of the above. b. metabolic acidosis
When oxygen is not available, cells switch to anaerobic
metabolism, which yields an acid called lactate, or lactic
acid.
, Tissue ischemia and a decrease in mitochondrial
oxygenation result in:
a. cellular dehydration
b. decreased ATP production
c. calcium accumulation outside the cell.
d. increased protein synthesis. b. decreased ATP
production
A decrease in oxygen delivery results in a decrease in ATP
production.
Injury to the endoplasmic reticulum due to hypoxic injury
results in:
a. sodium accumulation.
b. a decrease in protein synthesis.
