Surgical asepsis (sterile technique) - Answer- techniques used to destroy all pathogenic organisms (Injections/Catheter insertion/irrigation) chain of infection - Answer- • An infectious agent (pathogen) • A reservoir (source for pathogen growth) • A portal of exit from the reservoir • A mode of transmission • A portal of entry to a host • A susceptible host Medical asepsis=Clean Technique - Answer- Refers to practices and procedures used to control and to reduce the number of organisms present and to prevent the transfer of organisms (Suppository insertion/ Simple wounds) mode of transmission (1) Droplet (2) Contact - Answer- (1) coughing and or sneezing (2) via contaminated objects or surfaces and then touching one's own mouth, nose, or possibly eyes Breaking the chain of infection - Answer- eliminate microorganisms /eliminate reservoirs reduce transmission /reduce susceptibility Wound Classification (1) Acute (2) Chronic - Answer- (1) orderly and timely repair process; results in restoration of anatomical and functional integrity =trauma, surgical incision (2) Fails to proceed through an orderly and timely repair process to produce anatomical and function integrity• -=vascular compromise, chronic inflammation, repetitive insults to the tissue-Pressure Injuries Course of Infection by Stage - Answer- incubation, prodromal, illness, convalescence systemic - Answer- relating to the whole body rather than to only a part Nursing Diagnosis - Answer- During assessment, nurses gather objective findings, such as an open incision or a reduced caloric intake, and subjective data, such as a patient's complaint of tenderness over a surgical wound site tissue ischemia - Answer- point at which tissues receive insufficient oxygen and perfusion hyperemia; redness and heat - Answer- redness is vasodilatation blood vessel expansion Surgical Wounds - Answer- cut or incision that was intentionally made by a scalpel process of wound healing (1) primary Intention - Answer- surgical incision (edges approximated, closed, heals quickly) process of wound healing (2) Secondary intention healing - Answer- wound in which the tissue surfaces are not approximated and there is extensive tissue loss, formation of excessive granulation tissue and scarring process of wound healing (3) Tertiary intention healing - Answer- Wound is left open for 3-5 days to allow edema or infection to resolve Sign/Symptom (1) Redness (2) Edema (3) Ecchymosis - Answer- (1) Inflammatory response, infection, reaction to skin closure, dressing
