Pathophysiology, Immune Response, and
Cancer: Key Concepts for NSG 211 Exam 1
UPDATED ACTUAL Question and CORRECT
Answers
Pathophysiology The study of how diseases affect the normal
functions of the body. It combines the study of
pathology (structural changes) with physiology
(functional changes).
Etiology Cause of a disease.
Pathogenesis The mechanisms and processes of how a disease
develops and progresses.
Clinical Manifestations The signs and symptoms of a disease.
Epidemiology The study of the patterns, causes, and effects of
health and disease conditions in a population.
Incidence The number of new cases of a disease.
Prevalence The total number of cases of a disease.
Morbidity How many people have a disease.
, Individual-focused care Concentrates on the diagnosis, treatment, and
management of a single patient's disease. It
involves a one-on-one approach to care.
Population-focused care Also known as public health, addresses the
health needs of entire communities or groups.
This approach focuses on disease prevention,
health promotion, and identifying risk factors
within a population.
Cellular Adaptation Changes that occur to a cell's structure from
either physiological or pathological stressors.
Apoptosis Programmed cell death, controlled, normal
process that removes damaged or unneeded
cells.
Necrosis Uncontrolled cell death, caused by severe injury;
leads to inflammation and tissue damage.
Causes of injury - Ischemia
- toxins
- infections
- immune responses
- physical/chemical factors.
Atrophy A decrease in cell size, leading to a reduction in
the size of the organ or tissue.
Hypertrophy An increase in cell size due to an increased
workload, resulting in a larger organ.
Hyperplasia An increase in the number of cells in an organ or
tissue.
