Drainage, Pain, Redness, Swelling & Warmth
Drainage, Blueness, Redness, Pain & Pus
(a) grow best in warm, dark, moist environments with a food source and a host with low resistance.
The Chain of Infection involves the following links (in the proper order):
Susceptible Host, Infectious Agent, Reservoir, Portals of Entry, of Transmission & Portals of Exit
Portals of Exit, Reservoir, Infectious Agent, Modes of Transmission, Portals of Entry & Susceptible Host
Portals of Entry, Susceptible Host, Infectious Agent, Reservoir, Portals of Exit & Mode of Transmission
Infectious Agent, Reservoir, Portals of Exit, Modes of Transmission, Portals of Entry & Susceptible Host
How can healthcare providers can break the Chain of Infection? Check all that apply.
Washing hands
Rapid identification of organism
Employee Health
Standard Precautions
Wound care
Skin, cilia, mucous membranes, tears, Hydrochloric Acid, Inflammation, Fever, Cough/Sneeze and Immune System responses are all examples of (a) .
The body responses that increase heat loss during the course of a fever are:
Vasodilation, vasoconstriction, sweating & increased BMR
Vasodilation, shivering, increased BMR & increased heart rate
Vasodilation, sweating, curling up the body, increased BMR & lethargy
Vasodilation, sweating, lethargy & extending the body
In adaptive immunity, passively acquired immunity involves the body making antibodies in response to an antigen
True
False
Which one is an example of active naturally acquired immunity?
Antigens enter the body naturally; body creates antibodies and specialized lymphocytes against the antigen
Antibodies pass from mother to fetus via the placenta or via the mother's milk
Antigens are introduced in vaccines; body produces antibodies and specialized lymphocytes
Performed antibodies in immune serum are introduced by injection
In a Type (a) reaction, the antigen is an allergen. The second exposure to the antigen is worse.
An (a) reaction is severe and life threatening. It involves and drop in BP (hypotension) and airway constriction, among other reactions.
S&S of anaphylaxis involve:
(a)
What are S&S of a systemic infection?
Fever, chills, redness, drainage & headache
Fever, chills, mental confusion, headache & NVD
Fever, chills, redness, swelling & pain
Fever, redness, pain, warmth & swelling
In a Type __ reaction, antibodies ____ the cell the antigen is found on.
II Cytotoxic and destroy
0
A reaction in which the antigen combines with the antibody and is deposited on a tissue in the body is a Type (a) reaction.
T-cells that start the process but can take up to 24 hours before symptoms are noticeable is considered a Type (a) reaction.
Describe what happens in autoimmune disorders.
The single most important thing an NA can do to prevent the spread of disease/infection is (a) .
Wash hands, put on gown, put on mask or respirator, goggles or face shield and then gloves is called (a) PPE.
In doffing PPE, the ___ is the only piece of PPE that is not removed before leaving the resident's room if they have a disease such as TB.
Respirator or N95 mask
0
_____ precautions are used for every patient. We treat every patient/resident as if they potentially have an infectious disease.
Airborne
Droplet
Standard
_______ precautions are used to prevent the spread of pathogens that travel through the air after being expelled. They are carried by moisture, air currents or dust.
Airborne
Contact
Droplet
_____ precautions are use to prevent a resident from spreading infection by ____ contact with another person or object.
Airborne
Contact
Droplet
___ precautions are used to prevent diseases spread by ____ in the air. Talking, singing, sneezing, laughing, breathing or coughing are examples of how they can be spread.
Airborne
Contact

What does HIV and AIDS stand for?
In HIV, the virus attacks the "keeper" of the immune system.
CD4 cells
CD8 cells
____ cells allow long-term memory of disease.
B cells
T cells
Why are AIDS patients at risk for dying from opportunistic infections?
Titres are used to measure specific antibodies in the body.
True
False
(a) antigens are used to identify "self" from other foreign substances. They must be closely matched before a organ transplantation to increase the likelihood the body will not reject the transplanted organ.
What is an antigen? Why is it important in the immune system response?
What are examples of some Multidrug-resistant organisms (MDROs)?
C. diff, HIV & TB
C. diff, MRSA, & VRE
Individuals who can transmit a disease but do not show symptoms of the disease are known as:
Carriers
Incubators
Saprophytes
Immunosuppressed
