139
Q

any element, substance or force whether
living or non-living thing; the presence or absence
can initiate or perpetuate a disease process.

A

agent

140
Q

these are cells in our body like plasma cells and lymphocytes
that produce antibodies to neutralize harmful effects of the infectious agents
and body fluids in our body that possess substance that have antimicrobial
properties

A

humoral defense

141
Q

there are cells in our body like macrophages and neutrophils
involve in the process of phagocytocis

A

cellular defense

142
Q

sum total of an organism’s external
surrounding conditions and influences that affect
its life and development

A

environment

143
Q

environmental factors of disease

A

•Physical Environment
•climate- certain disease have seasonal distribution
•Geography and location
•Biologic Environment- living environment of man
consist of plants, animals and fellow human
beings.

144
Q

Time between exposure to infectious agent up to the time of appearance of the earliest signs and symptoms

A

incubation period

145
Q

2 types of incubation period

A

clinical and biological

146
Q

the time between exposure to a pathogenic organism and the onset of symptoms of a disease.

A

clinical incubation period

147
Q

The time taken by the parasite to complete its development in the definite host (from the time of entry of the infective larvae to the presence of microfilariae) is called the Intrinsic incubation period (Biological incubation)

A

biological incubation period

148
Q

As applied to patient, separation for the period of
communicability, of infected persons or animals
from others in such places and under such
conditions as to prevent or limit the effect of the
direct or indirect transmission of the infectious
agent from those infected to those who are
susceptible or who may spread the disease agent

A

isolation

149
Q

CATEGORIES OF ISOLATION

A

STRICT, contact, respiratory, tuberculosis

150
Q

ISOLATION
this category is designed to prevent transmission of
highly contagious or virulent infectious that may spread by direct
contact or droplet.

A

strict isolation

151
Q

ISOLATION
for less highly transmissible or serious infections,
for disease or conditions which are spread primarily by close or direct
contact.

A

contact isolation

152
Q

ISOLATION
o prevent transmission of infectious diseases
over short distance through the air

A

respiratory isolation

153
Q

ISOLATION
(AFB isolation)- for patient with pulmonary
tuberculosis who have a positive sputum smear or chest x-rays which
strongly suggest active tuberculosi

A

TUBERCULOSIS ISOLATION

154
Q

CATEGORIES OF PRECAUTIONS

A

enteric, drainage, blood/body fluid

155
Q

restriction of the activities of a well
persons or animals who have been exposed to a
case of communicable diseases during its period of
communicability to prevent disease transmission
during incubation of infection should occur.

A

quarantine

156
Q

Limitation of movement of those exposed to a
communicable disease for a period of time not
longer than the longest usual incubation period
of that disease.

A

absolute/complete quarantine

157
Q

Selective, partial limitation of freedom of
movements of contacts

A

modified quarantine

158
Q

pHASES

A

Pre pathogenesis, pathogenesis

159
Q

6 requirements for successful invasion

A
  1. Condition in the environment must be favorable to the agent or the agent must be able to adapt in the environment
  2. Suitable reservoirs must be present
  3. A susceptible host must be present
  4. Satisfactory portal of entry into the host
  5. Accessible portal of exit from the host
  6. Appropriate means of dissemination and transmission to a new host
