Porth’s Advanced Pathophysiology Concepts
Practice Test questions with answers
1. Describe how infections can act as a trigger for autoimmune diseases.
Infections have no role in autoimmune diseases.
Infections only affect the immune system temporarily.
Infections can trigger autoimmune diseases by causing the immune
system to mistakenly attack the body's own tissues after responding
to pathogens.
Infections strengthen the immune response against the body.
2. Describe how the nucleus contributes to cellular function.
The nucleus facilitates the transport of molecules across the cell
membrane.
The nucleus aids in the digestion of cellular waste.
The nucleus is responsible for energy production through ATP
synthesis.
The nucleus houses the cell's genetic material, which is essential for
regulating cell activities and protein synthesis.
3. What are two categories of cellular accumulations?
Correct answer
Endogenous and exogenous
1/55
,4. Describe the primary functions of innate immunity and adaptive immunity
in the immune response.
Innate immunity only responds to viruses, while adaptive immunity
responds to bacteria.
Innate immunity is slow and specific, while adaptive immunity is fast
and non-specific.
Innate immunity involves antibodies, while adaptive immunity does
not.
Innate immunity provides immediate, non-specific defense, while
adaptive immunity develops a targeted response to specific
pathogens.
5. Describe how passive transport differs from active transport in
cellular processes.
Both passive and active transport require energy but differ in the
types of substances they transport.
Passive transport involves the use of proteins, while active transport
does not.
Active transport occurs only in plant cells, while passive transport
occurs in animal cells.
Passive transport does not require energy, while active transport
requires energy to move substances against their concentration
gradient.
6. In a clinical scenario where a patient exhibits signs of acute inflammation,
which vascular changes would you expect to observe in the affected tissues?
No change in blood flow or tissue appearance.
Increased blood flow with no swelling.
2/55
, Decreased blood flow and reduced swelling.
Increased blood flow and swelling due to fluid leakage.
7. Tick-borne relapsing fever is characterized by recurring febrile episodes that
last approximately 3 days and are separated by afebrile periods of
approximately 7 days. Along with very high fever, patients may experience a
wide range of nonspecific symptoms such as headache, muscle pains,
nausea, and vomiting. Relapsing fever is caused by organisms (Image 2) that
can best be described as:
Micrococci
Streptococci
Vibrios
Staphylococci
Spirochetes
8. IgE is an important immunoglobulin because it:
Mediates some types of hypersensitivity (allergic reactions)
3/55
, Is generally responsible for an individual's immunity to invading
parasites
All of these are correct
Binds strongly to receptors on mast cells and basophils and, with
antigen, mediates the histamine and heparin from these cells
9. Describe the role of phagocytes in the innate immune response.
Phagocytes engulf and destroy pathogens as part of the innate
immune response.
Phagocytes produce antibodies to neutralize toxins.
Phagocytes release cytokines to stimulate inflammation.
Phagocytes activate T lymphocytes to enhance adaptive immunity.
10. What type of cells do B cells become after their initial exposure to an
antigen?
Memory cells
T cells
Plasma cells
Macrophages
11. Describe the process of facilitated diffusion and its significance in cellular
transport.
Facilitated diffusion requires energy to move molecules against their
concentration gradient.
Facilitated diffusion is a type of active transport that involves vesicle
formation.
