Q

IV. CHAIN OF INFECTION

A

Etiologic Agent
Reservoir
Portal of Exit
Mode of Transmission
Portal of Entry
Susceptible Host

26
Q

Method of Transmission
Three mechanisms:

A
  1. Direct Transmission
  2. Indirect Transmission
    a. Vehicle-born transmission
    b. Vector-borne transmission
  3. Airborne Transmission
27
Q
  • Immediate and direct
    transfer; or if the
    source and host are 3
    feet of each other
  • touching, biting,
    kissing, sexual
    intercourse
  • Sneezing, coughing,
    spitting, talking
A

Direct Transmission

28
Q

vehicle-born or
vector-borne

A

Indirect Transmission

29
Q

Droplets or dust containing infectious agents that is transmitted in the air/remain in the air for long periods

A

Airborne Transmission

30
Q

___________ substance that
serves as an intermediate
means to transport
/introduce an infectious
agent.

A

Vehicle-borne: Vehicle

31
Q

__________ animal or insect
that serves as an
intermediate means to
transport an infectious
agent.

A

Vector-borne: Vector

32
Q

inanimate objects/materials

A

Fomite

33
Q

V. BODY DEFENSES AGAINST
INFECTION

A
  1. Nonspecific Defenses
    a. Anatomic and Physiologic Barriers
    b. Inflammatory Response
  2. Specific Defenses
    a. Antibody-mediated Defenses
    b. Cell-mediated Defenses
34
Q

Nonspecific defenses:

  • Intact skin and mucous membranes
  • Nasal passages: cilia
  • Body orifice: saliva
  • Eye: tears
  • Stomach: high acidity
  • Vagina: Lactobacilli
A

Anatomic and Physiologic Barriers

35
Q

Nonspecific defenses

defensive response of the
tissues to an injurious or
infectious agent

A

Inflammatory Response: Inflammation

36
Q

5 signs of inflammatory response:

A
  1. Pain
  2. Swelling
  3. Redness
  4. Heat
  5. Impaired function of
    the part, if severe.
37
Q

SPECIFIC DEFENSE

Antibodies/Immunoglobulins
- part of body’s plasma proteins.
- major types: active and passive

A

Antibody-Mediated Defenses

38
Q

part of body’s plasma proteins

A

Antibodies/Immunoglobulins

39
Q

Antibodies/Immunoglobulins
2 major types:

A

active and passive

40
Q

Host produces antibodies in
response to artificial antigens
(vaccines) or natural antigens
(infectious microorganisms)

A

Active Immunity

41
Q
  • Acquired
  • The host receives natural
    (e.g., from a nursing
    mother) or artificial (e.g.,
    from an immune serum)
    antibodies produced by
    another source.
A

Passive Immunity

42
Q

SPECIFIC DEFENSE

  • lymphoid tissues release large numbers of activated T cells into the lymph system.
  • these T cells pass into the general circulation.
A

Cell-mediated defenses/cellular immunity

43
Q

VI. FACTORS INCREASING
SUSCEPTIBILITY TO INFECTION

A
  1. Age
  2. Heredity
  3. Level of Stress
  4. Nutritional Status
  5. Current medical therapy
  6. Preexisting medical process
44
Q
  • newborns and older
    adults have reduced defenses
    against infection.
A

Age

45
Q
  • some people have
    genetic susceptibility to certain
    infections
A

Heredity

46
Q
  • stress elevates blood
    cortisone decreases anti
    -inflammatory responses.
A

Level of Stress

47
Q
  • antibodies are proteins;
    Therefore, the body needs enough
    protein to boost immune system.
A

Nutritional Status

48
Q
  • e.g., radiation treatment, medications, procedures which penetrate sterile body cavities/require the skin to be cut
A

Current medical therapy

49
Q
  • e.g., Cancer, Diabetes Mellitus, Aplastic Anemia, Chronic Pulmonary Disease
A

Preexisting medical process

50
Q

DISINFECTING AND STERILIZING
__________ – used on skin or tissue

A

Antiseptic

51
Q

DISINFECTING AND STERILIZING
__________ – used on inanimate objects

A

Disinfectant

52
Q

Antiseptic and Disinfectant
Both have __________ and __________ properties.

A

bacteriostatic and bactericidal

53
Q

DISINFECTING AND STERILIZING
destroys all microorganisms

A

Sterilization

54
Q

Methods of Sterilization

A

✗ Moist Heat
✗ Gas
✗ Boiling Water
✗ Radiation

55
Q

PERSONAL PROTECTIVE EQUIPMENT (PPE)

A

✗ Gloves
✗ Gowns
✗ Mask
✗ Eyewear

56
Q

TRANSMISSION-BASED PRECAUTION

  • Private room that has
    a negative pressure;
    room with another
    client infected with
    the same
    microorganism
  • N95 respirator
  • surgical mask on the
    patient during
    transport
A

Airborne Precaution

57
Q

TRANSMISSION-BASED PRECAUTION

  • Private room; room
    with another client
    infected with the
    same microorganism
  • mask if working
    within 3 feet
  • surgical mask on the
    patient during
    transport
A

Droplet Precaution

58
Q

TRANSMISSION-BASED PRECAUTION

  • Private room; room
    with another client
    infected with the
    same microorganism
  • gloves; gown if with
    possibility of contact
    with infected surfaces
