/. What is the goal of inflammation? - Answer-✅To limit infection and further damage
and to initiate the adaptive immune response
/.What is exudate? - Answer-✅drainage
carries away bad things from cells
/.What do neutrophils indicate? - Answer-✅bacterial infection
/.What do eosinophils indicate? - Answer-✅allergies and parasites
/.What does a decrease in neutrophils and an increase in lymphocytes indicate? -
Answer-✅viral infection
B or T cells
these "REMEMBER"
/.What are bands? - Answer-✅Immature neutrophils; increased levels suggest acute
infection
/.What are monocytes? - Answer-✅increase in the blood d/t infection
macrophages
/.IgM is What? - Answer-✅FIRST RESPONDER
circulates in the body fluids
has 5 ways to pull antigens into clumps
/.IgG does what? - Answer-✅second immune response
can cross the placenta
/.IgA does what? - Answer-✅found in secretions on mucous membranes
prevents antigens from entering
,tears, saliva, breast milk
/.IgD does what? - Answer-✅found on the surface of B cells
acts as an antigen receptor
/.IgE does what? - Answer-✅found on mast cells in tissues
involved in allergic reactions
/.What is a type 1 IgE-Mediated allergic reaction? - Answer-✅IgE is release by plasma
cells which bind to mast cells
most common type of allergic reaction
histamine is released
inflammation, vasodilation, smooth muscle constriction
asthma, dermatitis, anaphylaxis can occur
/.What are clinical manifestations of an IgE-Mediated allergic reaction? - Answer-
✅bronchospasms
wheezing
rhinorrhea
urticaria
angioedema
dark circles under the eyes
anaphylaxis
/.What are first gen vs second gen antihistamines? - Answer-✅benadryl: first gen
loratidine: second gen
/.What are Dx we can do for an IgE-Mediated allergic reaction? - Answer-
✅immunoglobulin titers
patch testing
, /.What is therapeutic mgmt for an IgE-Mediated allergic reaction? - Answer-
✅antihistamine
mast cell degradation inhibitor
decongestant
epi
steroid
removing offending agent
ABCs
/.What is anaphylaxis? - Answer-✅systemic response
massive vasodilation
massive bronchoconstriction
low bp, can't breathe
fast or slow HR
/.What do we do for anaphylaxis? - Answer-✅steroids
epi!
airway!!
IVF
/.What are type 2 hypersensitivity reactions? - Answer-✅These are anitbody mediated
basically your body is eating itself
think hemolytic anemia
/.What are nursing implications for Type 2 reactions? - Answer-✅always follow blood
protocol!!!
RhoGam!!!
