1 Intro to Patho

Question 1

4 interrelated topics of pathophysiology

Answer 1

1 etiology
2 pathogenesis
3 clinical manifestations
4 treatments

Question 2

etiology

Answer 2

• study of CAUSES or REASONS for phenomena

- ID’s casual factors that, acting in concert, provoke a particular disease

Question 3

Idiopathic

Answer 3

cause for phenomena is UNKNOWN

Question 4

Iatrogenic

Answer 4

cause results from UNINTENDED or UNWANTED medical treatment

Question 5

Risk Factor

Answer 5

a factor that when present increases the likelihood of a disease

Question 6

clinical manifestations

Answer 6

sings, symptoms, + syndromes

Question 7

signs

Answer 7

objective/observed manifestation of disease

Question 8

symptoms

Answer 8

subjective feeling of abnormality in the body

Question 9

syndrome

Answer 9

etiology of signs + sympt has not yet been determined

Question 10

stages/clinical course

Answer 10

latent period
prodromal period
subclinical stage
acute clinical course
chronic clinical course

Question 11

latent period

Answer 11

time bw exposure of tissue to injurious agent + first appearance of signs/sympt

• also refers to a period during an illness when signs/sympt temporarily become mild or silent or disappear
• aka incubation time

Question 12

remission

Answer 12

decrease in severity, signs, sympt

-may indicate disease is cured

Question 13

prodromal period

Answer 13

time during which first signs/sympt appear indicating onset of disease

Question 14

subclinical stage

Answer 14

patient functions normally; disease process are well established

Question 15

acute clinical course

Answer 15

short-lived

-may have severe manifestation

Question 16

chronic clinical course

Answer 16

• may last months to years

- sometimes following acute course

Question 17

exacerbation

Answer 17

sudden increase in severity of disease, sings, or sympt

Question 18

convalescence

Answer 18

stage of recovery after a disease, injury, or surgical procedure

Question 19

sequela

Answer 19

subsequent pathologic condition resulting from an illness

Question 20

treatment application

Answer 20

understanding the etiology, pathogenesis, and clinical consequences of a particular disorder/disease/illness may determine which treatments could be helpful

Question 21

statistical normality in health and disease

Answer 21

estimate of diseases in a normal population, based on bell-shaped curve

Question 22

sensitivity

Answer 22

probability that a test will be POSITIVE when applied to a person w a particular condition

Question 23

specificity

Answer 23

probability that a test will be NEGATIVE when applied to a person without a particular condition

Question 24

epidemiology

Answer 24

study of the patterns of disease involving populations

-examining the occurrence, incidence, prevalence, transmission, + distribution of diseases in large groups of population

Question 25

endemic disease

Answer 25

native to a local region

Question 26

epidemic disease

Answer 26

spread to many people at the same time

Question 27

pandemic disease

Answer 27

spread to large geographic areas
