NR 283 Exam #1 questions with verified answers A+ Grade 2026\2027
Pathophysiology
- correct answer the study of how disease processes affect the function of the body
How is homeostasis maintained?
- correct answer negative feedback loops
Diagnosis
- correct answer identification of a disease
Etiology
- correct answer cause of disease
Idiopathic
- correct answer unknown cause
prophylaxis
- correct answer prevention of disease
Pathogenesis
- correct answer development of disease
Prognosis
- correct answer a forecast of the probable course and outcome of a disease or situation
Morbidity
- correct answer the disease rates within a group
, Epidemic
- correct answer A widespread outbreak of an infectious disease.
Atrophy
- correct answer decrease in cell size. Ex: shrinkage of skeletal muscle that occurs when a limb is
immobilized in a cast for several weeks.
Dysplasia
- correct answer cells vary in size and shape, large nuclei present, rate of mitosis is increased. Pap smear
tests for this on cervical cells.
Hyperplasia
- correct answer increased number of cells resulting in an enlarged tissue mass. Ex: uterine enlargement
in pregnancy.
Metaplasia
- correct answer when one mature cell type is replaced by a different mature cell type. ex: change in
respiratory tracts in cigarette smokers.
Anaplasia
- correct answer refers to cells that are undifferentiated with variable nuclear and cell structures and
numerous mitotic figures. Ex: malignant tumors
Hypoxia
- correct answer reduced oxygen in the tissue.
-interferes with ATP production in the cell, leading to loss of sodium pump out the cell membrane as
well as loss of cell functions.
Ischemia
- correct answer blockage that impedes blood flow
Necrosis
- correct answer tissue death ex: ischemia
