Question 1 pts
An adult patient arrives at the emergency department with a severe allergic reaction, characterized by hives, facial swelling, and difficulty breathing after a bee sting. After administering epinephrine and stabilizing the patient, what is the most appropriate next step in management?
Group of answer choices
The patient should be observed for up to 72 hours
The patient can be discharged once symptoms improve
Consider prophylactic intubation
Administer corticosteroids
Question 2 pts
In a cell experiencing ATP depletion, which of the following correctly describes the effect on different cellular processes?
Group of answer choices
Enhances glycolysis activity
Promotes protein synthesis
Increases sodium concentration inside the cell
Decreases intracellular calcium levels
Question 3 pts
An older adult presents with chest pain and is diagnosed with a myocardial infarction. The patient undergoes cardiac catheterization and receives thrombolytic therapy. Unfortunately, the patient’s condition worsens, and the heart muscle cells begin to die. Which cellular process is most likely responsible for the death of heart muscle cells in this scenario?
Group of answer choices
Necrosis
Autolysis
Apoptosis
Autophagy
Question 4 pts
In cell injury resulting from low oxygen levels, which primary function of oxygen is disrupted?
Group of answer choices
Oxygen serves as a structural component of cell membranes.
Oxygen directly regulates cell division and proliferation.
Oxygen generates ATP through the electron transport system.
Oxygen facilitates DNA repair mechanisms.
Question 5 pts
All of the following are the cellular components that are susceptible to cell injury EXCEPT:
Group of answer choices
Glycogen synthesis
Protein synthetic capacity
Membrane integrity
ATP generation
Question 6 pts
Which of the following is characteristic of cells?
Group of answer choices
A cell is a static structure.
All cells have the same shape and functions.
Organelles within a cell are randomly placed.
Cell organelles are organized to enable coordinated functioning.
Question 7 pts
What is a potential outcome when the plasma membrane of a cell is damaged?
Group of answer choices
Increased genetic stability
Compromised cell integrity
Increased protein synthesis
Enhanced ATP generation
Question 8 pts
Concerning historical viewpoints on inheritance, predating Mendel’s experiments:
Group of answer choices
DNA was considered the primary source of genetic information.
It was believed that only the maternal genes determined traits.
Traits were believed to be blended from both parents.
Dominant and recessive traits were already well understood.
Question 9 pts
Which one of the following is an accurate statement regarding the fundamentals of cellular pathology?
Group of answer choices
Disease is primarily a consequence of an individual’s genetic makeup, with limited influence from the environment.
Cell injury typically leads to cell death because it is more straightforward to generate a new cell than to repair an injured one.
Cells of the skin, heart, and brain can all regenerate when they are injured.
For almost any biological reaction, there is an opposite reaction.
Question 10 pts
Decreased tissue perfusion, reduced oxygenation, and diminished oxygen-carrying capacity are 3 of the 4 causes of cellular hypoxia. Which of the following substances is a well-known contributor to the fourth cause of cellular hypoxia?
Group of answer choices
Sulfur dioxide
Hydrogen peroxide
Cyanide
Methane
