Question | Answer |
---|---|
passive natural immunity | immunity passded from mother to baby last about 6 mos. may extend w/ breastfeeding |
pyrexia | fever- innnate immune response |
T cells are produced | Thymus |
innate immunity | based on DNA and exists within a species/subspecies |
complement system | series of protiens that increase cell wall permeability of pathogen |
Bcells | have/are memory cells. they remember a bug and produce antibodies to fight it next time it is encountered |
stemm cell differentiation | within first 8 divides |
antibody | protien that fights a disease- aka an immunoglobin |
antigen | pathogen/foriegn agent |
age effects on immune and lymphatic systems | neonates- immature immune system thymus gland changes in adolescents decreased ciliary action in resp and Gi tract(geriatrics) skin loses effectiveness as barrier(too thin) |
chrinic diseases that may decrease immune response | COPD, DM, HTN, REnal or liver disease, Cancer, ALCOHOL OR DRUG USE |
corticosteroids | decrease immune response - used to treat autoimmune (esp.SLE exacerbations) |
attenuated vaccines | only offer part of the virus, it mediates the same response as whole virus, but without causing disease |
common autoimmune diseases | RA, SLE, psoriasis, sjogren's, |
alcohol and immunity | long term alcohol use is the largest cause of immune malfunctions |
humoral immuntiy | the antibidy production caused by initial antigen response (B cells response |
specificity | antigen- antibody response are specific to particular pathogens |
antitoxin | produced by antibody against pathogenic toxins |
FFP | fresh frozen plasma- important because it contains large amounts of immunoglobulins |
Tcells | responsible for secondary cellular response |
passive artificial immunity | administration of antibody for a disease- short term |
Iatrogenic | caused by treatement |
why substance abusers are considered immunocompromised | chronic substance abuse suppresses heaptic function |
1st shots | HBV at birth, then first baby shots at 8 weeks |
swelling | caused by vasodilation |
assessment findings- infection | fever, tachycardia, malaise, swelling or pain in lymph nodes. redness pain is a secondary immune response |
sepsis mortatlity rates | 40% normally healthy individual >90% for immunocompromised |
CD4+ t cells | tell the viral load - if .200cells/mm3 then AIDS diagnosis |
CAndidiasis | most common opportunistic infection |
determination of shingles-objective S | rash follows a single dermatome (single nerve pathway) |
anaphalaxis treatment | Epinephrine is first line of defense diphenhydramine is a secondary response |
staging Cancer | depends on lymph node involvement- I- 1 node, II- 2nodes same side of diaphragm, III- 2 or more both sides, 4 same as II plus mets |
RA treatment | corticosteroids for decreasing autoimmune response, NSAIDS for pain control |
