Document Content and Description Below

MULTIPLE CHOICE 1. The primary use for suture is essentially to: a. strengthen, re-form, and close tissue. b. ligate, suture, and close tissue. c. ligate, strengthen, and stop bleeding. d. clamp,... divide, and attach tissue. ANS: B Suture is a generic term for all materials used to sew severed body tissues together and to hold these tissues in their normal position until healing takes place; to suture is to stitch together cut or torn edges of tissue. A ligature is a strand of suture material used to tie off (seal) blood vessels for the prevention of minor bleeding, or to isolate a mass of tissue for excision (cut out). A variety of suture materials are available for ligating, suturing, and closing the wound. REF: Page 174 2. The ideal suture material is one that has handling characteristics such as: a. memory. b. slickness. c. ease of tying. d. removable knots. ANS: C Key features used to evaluate the general properties of suture material are (1) physical characteristics, (2) handling characteristics, and (3) tissue reaction characteristics. Handling characteristics of suture material are related to pliability (how easily the material bends) and the coefficient of friction (how easily the suture slips through tissue and can be tied). REF: Page 174 3. Tissue reaction characteristics are important in a suture material because: a. the suture should absorb and nourish the healing tissue. b. the suture should not cause tissue inflammation or an allergic response. c. the suture should not support infection. d. the suture should not cause tissue inflammation or an allergic response and the suture should not support infection ANS: D The ideal suture material is one that causes minimal inflammation and tissue reaction while providing maximal strength during the lag phase of wound healing. Tissue reaction characteristics include inflammatory and fibrous cell reaction, absorption, potentiation of infection, and allergic reaction. [Show More]
