Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

33 notecards = 9 pages (4 cards per page)

immunity study guide answers

front 1

the immune systems main job is

back 1

protects the body from pathogens, infection, abnormal cells

front 2

the lymphatic systems main job is

back 2

filters lymph, removes excess fluid, returns fluid to circulation

front 3

how do the immune and lymphatic system work together ?

back 3

lymphatic system transports/filters; immune system identifies and destroys pathogens

front 4

pathogen enters the body through

back 4

skin breaks, respiratory tract, gastrointestinal tract, urinary tract

front 5

first line of defense tries to stop it

think: where can bacteria or viruses get in?

back 5

skin, mucous membranes, tears, earwax

front 6

signs of inflammation

back 6

redness, warmth, swelling, pain

front 7

the immune system recognizes something is _______ and being to respond

back 7

foreign

front 8

think about how the body is responding:

  • is this the immediate, general response that happens the same way for all pathogens?
  • or is this targeted response where the body recognizes a specific antigen?

back 8

adaptive immunity

front 9

how is the body specifically responding?

  • is the body producing antibodies that circulates in body fluids ?
  • or is the body using cells to directly attack and destroy infected calls?

back 9

  • humoral immunity (B CELLS)
  • cell medicated immunity (T CELLS)

front 10

B cells think what?

back 10

antibodies

front 11

T cells , think what?

back 11

destroy infected cells

front 12

where do B cells mature

back 12

bone marrow

front 13

where do T cells mature

back 13

thymus

front 14

what type of immunity is B cells

back 14

humoral

front 15

what type of immunity is T cells ?

back 15

cell mediated

front 16

what type (active or passive) lasts the longest?

back 16

active immunity.

front 17

which type (active or passive) works immediately

back 17

passive immunity

front 18

histamine causes

back 18

vasodilation, increased permeability, swelling

front 19

leukotrienes cause

back 19

bronchoconstriction

front 20

which involves in asthma?

back 20

leukotrienes

front 21

which is involved in allergic reactions ?

back 21

histamine

front 22

why are neonates at higher risk

back 22

immature immune system

front 23

why are older adults at higher risk

back 23

decreased immune response, thinner skin, chronic illness

front 24

immunosuppression

list three causes

back 24

  • chemotherapy, steroids, medications
  • chronic illness
  • autoimmune disease or treatment

front 25

priority in neutropenic precatuins

back 25

hand hygiene

front 26

fever helps the body by doing what?

back 26

creates a hostile environment for pathogens/ enhances immune response

front 27

why should we treat a fever

back 27

based on symptoms, patient condition, and cause (not just temp number)

front 28

antigen

back 28

foreign substance

front 29

antibody

back 29

protein that binds antigen

front 30

first line of defense

back 30

skin and mucous membranes

front 31

spleen function

back 31

filters blood and removes pathogens

front 32

thymus function

back 32

T cell maturation

front 33

a patient is receiving chemotherapy

-explain why they are at increased risk for infection and what the nurse should prioritize

back 33

  • decreased white blood cells- increased infection risk
  • prioritize infection prevention; hand hygiene, neutropenic precautions, monitoring
