PATHOPHYSIOLOGY
Ace your preparation with this NURS 6501 Advanced
Pathophysiology Exam 1, designed to assess foundational
knowledge of disease processes in advanced nursing practice. It
focuses on cellular changes, disease mechanisms, and system-
based pathophysiology concepts. The exam strengthens clinical
reasoning and diagnostic thinking for evidence-based patient
care. Suitable for graduate nursing students and advanced
practice learners.
What can cause cell injury? ...... ANSWER ....... lack of
oxygen (hypoxia), free radicals, caustic or toxic chemicals,
infectious agents, inflammatory and immune responses,
genetic factors, insufficient nutrients, or physical and
mechanical trauma from many causes
What are the four biochemical themes associated with cell
injury? ...... ANSWER ....... (1) ATP depletion, resulting in
mitochondrial damage; (2) accumulation of oxygen and
, Page 2 of 28
oxygen-derived free radicals, causing membrane damage;
(3) protein folding defects; and (4) increased intracellular
calcium concentration and loss of calcium steady state.
What is the sequence of events in cell death? ...... ANSWER
....... decreased ATP production, failure of active transport
mechanisms (the sodium-potassium pump), cellular
swelling, detachment of ribosomes from the ER, cessation
of protein synthesis, mitochondrial swelling as a result of
calcium accumulation, vacuolation, leakage of digestive
enzymes from lysosomes, autodigestion of intracellular
structures, lysis of the plasma membrane, and death.
What happens first in a hypoxic injury? ...... ANSWER .......
the cessation of blood flow into vessels that supply the cell
with oxygen and nutrients (ischemia)
What is oncosis? ...... ANSWER ....... accumulation of
water causing cellular death
What can cause a reperfusion injury? ...... ANSWER .......
restoration of oxygen by oxidative stress, increased
, Page 3 of 28
intracellular calcium concentration, inflammation, and
complement activation.
How can deprivation of essential nutrients (proteins,
carbohydrates, lipids, and vitamins) lead to cell injury? ......
ANSWER ....... by altering cellular structure and function,
particularly of transport mechanisms, chromosomes, the
nucleus, and DNA
What are the two categories of intracellular accumulations?
...... ANSWER ....... (1) normal cellular substances, such as
water, proteins, lipids, and carbohydrate excesses; and (2)
abnormal substances, either endogenous (e.g., from
abnormal metabolism) or exogenous (e.g., a virus).
What mechanisms cause accumulations? ...... ANSWER
....... (1) An endogenous substance is produced in excess or
at an increased rate; (2) an abnormal substance, often the
result of a mutated gene, accumulates; (3) an endogenous
substance is not effectively catabolized; and (4) a harmful
exogenous substance accumulates because of inhalation,
ingestion, or infection.
