        Help!  

Question
Answer
adhesion   union of 2 surfaces or structures that are normally separate  
🗑
allergen   any substance that brings on the manifestations of an allergy  
🗑
allergy   abnormal hypersensitivity by an individual to 1 or more substance  
🗑
antigen   a substance which induces the formation of antibodies; may be introduced into the body or formed w/in the body  
🗑
antitoxin   an antibody capable of neutralizing a specific toxin  
🗑
attenuated   less virulent; diluted; weakened  
🗑
cicatrix   scar left by a healed wound  
🗑
clean-contaminated   primary closure, wound drain, minor break in aseptic technique occurred. no inflammation  
🗑
clean    
🗑
closed   skin is intact, but underlaying tissue is injured  
🗑
collagen   white protein contained in the connective tissues and bones  
🗑
contaminated   open fresh traumatic wound of less than 4 hrs old or major break in aseptic technique  
🗑
debridement   removal of foreign material; cutting away dead/devitalized tissues; open, clean wound where anaerobic organisms cannot survive  
🗑
dirty & infected   old traumatic wound over 4 hrs old, from a dirty source or the presence of neuroic tissue, fecal matter  
🗑
disruption   when the orderly closure of a wound is altered; usually suture lines break down, decreasing support of abdominal wall over peritoneal contents  
🗑
endotoxins   bacterial toxins which are liberated only when the bacterial cell is destroyed  
🗑
fibrinogen   constituent of blood that aids in coagulation  
🗑
granulation   formation of new tissue, composed largely of newly growing capillaries which form in types of wounds left open  
🗑
granulation tissue   fibrous connective tissue containing blood vessels and lymphatics; not visible in 1st intention healing  
🗑
hemotoma   tumor or swelling which contains blood  
🗑
hemostasis   control of bleeding  
🗑
immune response   the production of antibodies in response to the presence of a corresponding antigen  
🗑
immune   not susceptible or responsive to a disease or having a high degree of resistance to a disease  
🗑
immunization   process of rendering a patient immune  
🗑
ischemia   decrease of blood supply to tissue  
🗑
keloid   dense, unsightly connective tissue or excessive scar fromation; removed surgically  
🗑
macrophage   type of WBC's the engulfs  
🗑
necrosis   death of tissue cells  
🗑
open, clean   skin is broken & the object or condition surrounding the injury are relatively clean  
🗑
open, complicated   skin/underlying tissue are injured or destroyed by crushing, burning or implantation of a foreign object  
🗑
open, simple   skin is broken, but the underlying tissue is uninjured  
🗑
sero-sanguinous   blood-tinged or colored serous drainage  
🗑
serum   watery fluid taken from the blood of an animal rendered immune against a pathogenic organism which is injected into a pt to protect against the disease resulting from a pathogenic organism  
🗑
surgical incision   caused by a purposful cut thru intact skin  
🗑
toxin   a poisonous substance  
🗑
toxoid   a toxin treated so as to destroy its toxicity, but still capable of inducing formation of antibodies on injection  
🗑
trauma   injury to body tissue produced by violence of any chemical, thermal or other extrinsic agent  
🗑
traumatic injury   caused by chemical, thermal or other factors  
🗑
vaccination   inoculation w/a vaccine  
🗑
vaccine   suspension of infectious agents given to establish resistance to an infectious disease  
🗑
1st intention healing   healing is by primary union  
🗑
2nd intention healing   wound is not closed  
🗑
3rd intention healing   similar to second intention healing except wound is sutured, either delayed or secondary  
🗑
2nd or 3rd intention healing   healing may produce a weak union, which may be conducive to incisional heriation later  
🗑
basic types of wounds   chronic wound, surgical incision, traumatic injury  
🗑
clean wound   elective procedure; wound made under ideal conditions, primary closure, no drain, no breaks in aseptic tech, no inflammation, alimentary, genitourinary or resp. tract or oropharyngeal cavities are not entered  
🗑
contaminated wound   open fresh traumatic wound less than 4 hrs old, 1-5% infection rate, acute, nonpurulent inflammation present, entry into biliary or genitourinary tracts w/infected bile or urine present  
🗑
puncture   a hole, wound, or perforation made by puncturing  
🗑
laceration   a torn and ragged wound w/irregular edges  
🗑
healing & pt physical condition   wound healing is impaired by deficiencies in zinc, protein, carbohydrates & vit. a,b,c; radiation in large doses preoperatively slows the healing process; carbs are necessary in healing  
🗑
eventration   partial protrusion of the abdominal contents thru a opening in the abdominal wall  
🗑
antibody   protein substance developed by the body in response to the presence of an antigen that counteracts the antigen  
🗑
immunology   study of the immune system  
🗑
artificially acquired passive immunity   antibodies produced elsewhere are injected in the form of immune serums  
🗑
bougie   instrument for exploring and dilating canals, especially the male urethra & the esophagus  
🗑
drain   exit for discharge of abnormal fluid accumulations or to draw off fluid  
🗑
lumen   hollow opening thru a tube or catheter  
🗑
catheters   use to allow a method for insulation, drainage, irragation & medication  
🗑
drains   used to prevent hematomas; may be placed in the cavity and exteriorized thru a seperate stab wound  
🗑
tubes   used to decompress the GI tract  
🗑
Penrose drain   uses capillary action as the drainage mechanism  
🗑
T-tube   used for common bile duct exploration  
🗑
levine tube   single lumen tube used for gastric decompression connected to gravity drainage or intermittent suction  
🗑
3 primary parts of a tracheostomy tube   obturator, outer cannula tube, inner cannula tube  
🗑
pharyngeal airway tube   is inserted thru the mouth  
🗑
chest tube   is not used to drain esophageal abscesses; are always connected to an underwater seal drainage system  
🗑
pleur-evac   is a self-contained drainage system units  
🗑
common inhalant allergen   dust,perfume,pollen,chocolate,plants,fur  
🗑
symptoms of acute inflammatory response   redness,heat,swelling,pain & disordered function  
🗑
treatment of acute inflammation   rest the inflammed part, open drainage to allow bacteria to escape & to relieve tension & swelling of inflamed part; supplement body's natural defenses w/specfic drugs such as antibiotics  
🗑
genetic immunity   is programmed into one's genetic makeup  
🗑
