1

what is the critical mass necessary to cause infection of a wound

100k/gram of tissue

2

which is MC pathogen that leads to infection of a minor surgery laceration repair?

staph aureus

3

which of the following statements about wound closure is incorrect?

--skin position is achieved by creating an inverted suture

4

which of the following statements about wound closure is correct?

--hemostasis is obtained prior to wound closure by either direction pressure or clamping
--skin apposition is achieved by taking a wider bite to use fewer sutures
--tension is reduced by undermining the dermis from the superficial fascia

5

primary union

type of healing that occurs in clean wounds caused by shearing forces that have been closed w/in 6 hours of trauma

6

secondary union

types of healing that occurs by closing a wound 4 days after initial trauma that has been cleansed irrigated & debrided

7

tertiary union

Allowing for granulation & reepithelialization that is recommended for wounds w/ significant tissue loss or devitalization

8

dirty wound

type of wound that is older than 5 hours & prone to infection

9

throw =

each know of a suture is used to close a wound

10

bite =

amount of tissue taken when placing a suture needle in closing a wound

11

deep sutures =

typically absorbable for use in final skin closure

12

superficial sutures =

typically nonabsorbably for use in final skin closure

13

simple interrupted sutures

MC. 1/4 bite placed 1/4 apart used on upper extremity or trunk that requires removal of any excess tissues

14

vertical mattress sutures

sutures used on the thin skin of flexural surfaces

15

horizontal mattress sutures

sutures variation that provides deep closure support & increased eversion

16

apical suture

type of suture that draws tip of tissue into a place through a deep layer of the dermis to maintain circulation

17

subcuticular suture

type of suture used to avoid prominent suture marks

18

subcuticular suture

type of suture used to avoid prominent suture marks

19

absorbable suture

included polyglycolic acid for good know security, polygylcan-910 for good workability and gut

20

nonabsorbable suture

includes monofilament nylon for good tensile strength, polypropylene for subcuticular suture & dacron for good knot security

21

sings of infection include erythema that extends beyond ___cm & induration greater than ____ cm

1, 0.5
