PATHO MARYVILLE NURS 611 TEST 1 2023
QUESTIONS AND ANSWERS 100% CORRECT
GRADED A+
Apoptosis - ANSWER programmed death such as inflammation
Necrosis - ANSWER cellular injury such as MI, hypoxia
Atrophy - ANSWER physiologic atrophy of the thymus gland in childhood
Hypertrophy - ANSWER increase in cell size
Physiologic hypertrophy would be increase in myocardial cell size r/t endurance
training
Pathologic hypertrophy would be secondary to disease such as HTN
Hyperplasia - ANSWER increase in number of cells
Compensatory hyperplasia would be the regeneration of liver cells when 70% of
liver is removed
Pathologic hyperplasia would be seen in the endometrium
Metaplasia - ANSWER Replacement of different cells (think metamorphosis)
Ex: normal columnar ciliated epithelial cells of the bronchial lining have been
replaced by stratified squamous epithelial cells
Dysplasia - ANSWER Not a form of cellular adaptation

QUESTIONS AND ANSWERS 100% CORRECT
GRADED A+
ATP - ANSWER Adenosine Triphosphate is energy that needs oxygen. aerobic
metabolism
What happens when there is a reduction in ATP? - ANSWER There is a failure
of the Na+ K+ pump and the Na+ Calcium exchange. This ultimately leads to an
intracellular accumulation of Na+ and Calcium and diffusion of K+ out of the cell.
When K+ leaves the cell, more Na+ and water go into the cell which causes
swelling
What happens when oxygen reserves are depleted? - ANSWER anaerobic
metabolism (glycolysis)
Free radical - ANSWER An electrically uncharged atom(s) that has an
unpaired electron. Having one electron that is unpaired makes the atom unstable
so the atom either has to take an electron from another molecule or give one
away
What is a consequence of leakage of lysosomes during chemical injury? -
