portage pathophysiology exam 1 Questions With Accurate
Answers 100% Guarantee Pass 2026/2027
1. If a drug were to disrupt the function of the cell membrane, which of the
following processes would be most directly affected?
Transport of materials into and out of the cell
Synthesis of proteins
Cellular respiration
Cell division
2. Name the type of necrosis. The best example of this necrosis is the heart
tissue undergoing a myocardial infarction.
Liquefactive Necrosis
Fat Necrosis
Caseous Necrosis
Coagulative Necrosis
3. Describe the relationship between metaplasia and dysplasia in cellular
processes.
Metaplasia and dysplasia are unrelated processes in cellular
pathology.
Persistent metaplasia can lead to dysplasia, indicating a
progression of abnormal cellular changes.
Dysplasia is a reversible process that does not relate to metaplasia.
Metaplasia is a type of apoptosis that leads to dysplasia.
,4. Describe how Barrett esophagus exemplifies the concept of dysplasia in
cellular pathology.
Barrett esophagus is characterized by abnormal changes in the
cells lining the esophagus, indicating dysplasia.
Barrett esophagus involves programmed cell death, which is
apoptosis.
Barrett esophagus is a type of tissue necrosis due to lack of blood
supply.
Barrett esophagus shows a normal cellular structure without any
changes.
5. A 45-year-old male presents with symptoms that could indicate a chronic
illness. Considering the factors that influence diagnosis, which of the
following scenarios would most likely lead to a more accurate diagnosis?
Considering his lifestyle choices, such as diet and exercise, along
with his age and gender.
Focusing solely on his age and ignoring lifestyle factors.
Assuming his symptoms are typical for his age without further
investigation.
Only considering his race and not his age or lifestyle.
6. If a cell's active transport mechanisms are impaired, what physiological
consequence might occur regarding ion balance?
Decreased cell membrane permeability
Disruption of ion balance
Enhanced nutrient absorption
Increased energy production
, 7. Describe how membrane potential contributes to cellular communication.
Membrane potential regulates the synthesis of lipids in the cell.
Membrane potential allows for the generation and propagation of
action potentials, enabling communication between cells.
Membrane potential is involved in the breakdown of glucose.
Membrane potential controls the movement of water across the cell
membrane.
8. What is one primary function of a membrane potential in cells?
It helps in the transmission of electrical signals.
It aids in protein synthesis.
It stores genetic information.
It facilitates cellular respiration.
9. An example of necrosis would be:
fingernail clippings
gangrene
strands of hair on a hairbrush
dead skin cells on the washcloth when one is taking a bath
10. What is the definition of apoptosis?
Cellular inflammation
Programmed cell death
Uncontrolled cell growth
Cellular necrosis
