40
Q

How long can mrsa survive on a surface

A

7 months on surfaces

41
Q

Difference between bacteria and virus

A

Bacteria can reproduce on their own, virus needs a host

42
Q

Why do anti bodies not work on virus and how do you stop them?

A

Virus has no biochemical material so antibodies can’t stop them. Antivirals work bu stopping virus from entering cell

43
Q

Debridgement

A

Removal of dead cells so healing process can take place

44
Q

What are the three natural defenses of the body

A

Prevention, inflammatory process and neutralization

45
Q

What happens when body comes into contact with antigen

A

Body produces antibody to combat it. Further, the body’s plasma cells in the lymph system comes into contact with the antigen and then produces the antibody from there

46
Q

Naturally acquired active immunity

A

Contracting a disease and your body produces antibodies to combat them

47
Q

Naturally acquired passive immunity

A

Getting antibodies or immunity from parent

48
Q

Artificially acquired active immunity

A

Getting a vaccine for the purpose of producing antibodies for the virus

49
Q

Artificially acquired passive immunity

A

Having antibodies from something or someone else transplanted into you

50
Q

Trauma

A

Physical agents that cause disease or injury

51
Q

Mechanical violence

A

Any external injury; all kinetic energy that causes change in organ

52
Q

Wound

A

Break in skin or other body membranes in the underlying tissue

Q

Contusion

A

Produces black and blue underlying tissue is involved. Not dermis. Causes interstitial bleeding

55
Q

Missile

A

Wound caused by a flying object

56
Q
