Introduction to Pathophysiology
Etiology - Answer-Study of the causes or reasons for a particular disease or injury.
Idiopathic - Answer-Cause is unknown.
Iatrogenic - Answer-Cause results from unintended or unwanted medical treatment.
Pathogenesis - Answer-The development or evolution of a disease, from the initial
stimulus to the ultimate expression of the manifestation of the disease.
Description of how etiological factors alter _____________ ________ and lead to
_______ _____________ that are observed in a particular disorder/disease. - Answer--
physiologic function
- clinical manifestations
Signs of disease - Answer-Manifestations of disease that are observed.
Symptoms - Answer-The subjective feelings of an abnormality in the body.
The feeling of nausea is a symptom or a sign? - Answer-Symptom
Vomiting is objectively observed as a symptom or a sign? - Answer-Sign
Syndrome - Answer-When the etiology of a particular sets of signs and symptoms has
not yet been determined.
Latent period
(in the case of infectious diseases it is call an incubation period) - Answer-The interval
between exposure of a tissue to an injurious agent and the first appearance of signs
and symptoms.
Prodromal period (or prodrome) - Answer-Refers to the appearance of the first signs
and symptoms indicating the onset of a disease.
Nonpecific symptoms like headache, malaise, anorexia, and nausea are examples of
what? - Answer-Prodromal symptoms
Acute phase - Answer-The disease reaches its full intensity, and signs and symptoms
attain their greatest severity.
Silent period or latent period - Answer-Sometimes during the course of a disease, the
s&s may become mild or even disappear fro a time.
Subclinical stage - Answer-during which the patient functions normally, although the
disease processes are well established.
Acute clinical course: - Answer-Short-lived; may have sever manifestations. Measured
hours, days, or a few weeks.
Chronic clinical course: - Answer-May last months to years, sometimes following an
acute course.
Exacerbation: - Answer-A sudden increase in severity of disease of S&S.
Remission: - Answer-Decrease in severity, signs, or symptoms: may indicate disease is
cured. (Sometimes defined as longer than 5 years).
Convalescence: - Answer-Stage of recovery after a disease, injury, or surgical
procedure.
Sequela (plural: sequelae) - Answer-Occasionally a disease produces a subsequent
pathologic condition. For example, the sequela of an inflammatory process might be
