MICRO UTA EXAM 4 QUESTIONS WITH 100% CORRECT ANSWERS
characteristics of infectious disease - Correct Answer--disease
-infection
-signs and symptoms
-syndrome
-signs and symptoms help direct towards diagnosis
-some patients are asymptomatic/subclinical = only
signs can be observed thru correct testing *ex: patient w/herpes and no symptoms
disease - Correct Answer--a condition where normal
structure and/or function are damaged or impaired
infection - Correct Answer--invasion of pathogen or parasite that lead to disease -evidence for infection comes from signs and symptoms
signs - Correct Answer--things that can be directly measured by clinician
-ex blood cell counts symptoms - Correct Answer--things felt by patient that cannot be clinically measured
-ex nausea
syndrome - Correct Answer--groups of signs and symptoms that help indicate a particular disease
classification of disease - Correct Answer--WHO's international classification of diseases (IDC) is used globally to classify and monitor diseases
-diseases can be: infectious, communicable, iatrogenic, nosocomial, zoonotic, non-
communicable, and non-infectious
infectious disease - Correct Answer--disease caused
by direct effect of a pathogen
communicable disease - Correct Answer--capable of
spreading person-to-person (contagious - easily spead)
iatrogenic disease - Correct Answer--disease acquired as result of medical procedure nosocomial disease - Correct Answer--disease acquired from a hospital environment
zoonotic disease - Correct Answer--disease acquired
from an animal
non-communicable disease - Correct Answer--
disease obtained from non-living thing such as soil or contaminated object
non-infectious disease - Correct Answer--disease not caused by pathogen
periods/stages of disease - Correct Answer--
infectious disease follow 5 stages
1. incubation
2. prodromal
3. illness
4. decline
5. convalescence
incubation stage of disease - Correct Answer--
initial entry of pathogen
-replication begins prodromal stage of disease - Correct Answer--
replication continues
-host shows signs and symptoms
illness stage of disease - Correct Answer--signs and symptoms are most severe in host
decline stage of disease - Correct Answer--pathogen
number start to decrease
-host's immune system is weak and vulnerable to secondary infection
convalescence stage of disease - Correct Answer--
host starts to recover
acute vs. chronic disease - Correct Answer--illness period can be variable
-acute disease
-chronic disease
-latent disease
acute disease - Correct Answer--relatively short -hours, days, week
