Quiz #5 Flashcards
what is the critical mass necessary to cause infection of a wound
100k/gram of tissue
which is MC pathogen that leads to infection of a minor surgery laceration repair?
staph aureus
which of the following statements about wound closure is incorrect?
–skin position is achieved by creating an inverted suture
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
primary union
type of healing that occurs in clean wounds caused by shearing forces that have been closed w/in 6 hours of trauma
secondary union
types of healing that occurs by closing a wound 4 days after initial trauma that has been cleansed irrigated & debrided
tertiary union
Allowing for granulation & reepithelialization that is recommended for wounds w/ significant tissue loss or devitalization
dirty wound
type of wound that is older than 5 hours & prone to infection
throw =
each know of a suture is used to close a wound
bite =
amount of tissue taken when placing a suture needle in closing a wound
deep sutures =
typically absorbable for use in final skin closure
superficial sutures =
typically nonabsorbably for use in final skin closure
simple interrupted sutures
MC. 1/4 bite placed 1/4 apart used on upper extremity or trunk that requires removal of any excess tissues
vertical mattress sutures
sutures used on the thin skin of flexural surfaces
horizontal mattress sutures
sutures variation that provides deep closure support & increased eversion
apical suture
type of suture that draws tip of tissue into a place through a deep layer of the dermis to maintain circulation
subcuticular suture
type of suture used to avoid prominent suture marks
subcuticular suture
type of suture used to avoid prominent suture marks
absorbable suture
included polyglycolic acid for good know security, polygylcan-910 for good workability and gut
nonabsorbable suture
includes monofilament nylon for good tensile strength, polypropylene for subcuticular suture & dacron for good knot security
sings of infection include erythema that extends beyond ___cm & induration greater than ____ cm
1, 0.5
