Maryville Patho Exam 1 Questions And
Answers 2025
Apoptosis -
correct answer ✅Programmed cell death
Necrosis -
correct answer ✅Rapid loss of plasma membrane structure,
organelle swelling, mitochondrial dysfunction
Atrophy -
correct answer ✅Degeneration of cells
Hypertrophy -
correct answer ✅Swelling of cells
Hyperplasia -
correct answer ✅Increase in number of cells
Metaplasia -
correct answer ✅Replacement of cells, may not be functional
Loss of ATP effect on cells -
correct answer ✅Sodium-potassium pump failure. Intracellular
sodium, extracellular potassium leads to edema
Effect of oxygen depletion -
correct answer ✅Anaerobic metabolism (glycolysis)
Free radical -
correct answer ✅electrically charged atom/atoms with unpaired
electron--unstable. Steals molecules to stabilize.
Lysosome leakage from cell injury -
correct answer ✅Digestion of cellular organelles, halts DNA/RNA
, Maryville Patho Exam 1 Questions And
Answers 2025
Ethanol -
correct answer ✅Metabolized to acetaldehyde--liver dysfunction
over time
Peroxisomes -
correct answer ✅Detoxify ethanol, creates hydrogen peroxide
Most vulnerable to radiation -
correct answer ✅DNA
Effects of aging -
correct answer ✅Muscular atrophy (sarcopenia), stiffness/rigidity
of systems
Stiffness/rigidity of systems -
correct answer ✅Peripheral vascular resistance increase,
decreased HCL and stomach emptying, decreased immune
response, decreased total body potassium, increased extracellular
compartment
Dehydration s/sx -
correct answer ✅tachycardia, weak pulses, dizziness, postural
hypotension
Thirst response -
correct answer ✅Osmoreceptors activated by increased osmotic
pressure in plasma.
At risk of FVD -
correct answer ✅Infants (75-80% tbw), obese, elderly
