Q

A wound w tissue loss

severe laceration

not approximated

WOUND IS LEFT OPEN TO HEAL=LONGER HEALING TIME

GRANULATION

higher risk of infection

example; DECUBITUS (PRESSURE) OR LACERATION OR BURNS

16
Q

What are some key steps to ensure appropriate wound healing?

A

keep surrounding skin and tissue clean and dry

adequate O2 & nutrition to site; position to prevent pressure

dressings, stockings, drains applied and position correctly to reduce risk of lymphedema

report S/S infection immediately

nutrition and optimized glucose levels aid in healing process

17
Q

swelling or distention in the area of wound and

sanguineous drainage from a surgical drain

A

hemorrhage

18
Q

if internal hemorrhage is extensive what happens

A

hypovolemic shock which =

fall in BP;
rapid, thready pulse;
increased resp. rate; diaphoresis;
cold, clammy skin

19
Q

fall in BP;
rapid, thready pulse;
increased resp. rate; diaphoresis;
cold, clammy skin

are sign of what

A

hypovolemic shock if hemorrhage occurs

20
Q

what are some other cases that can occur in hemorrhage

A

hematoma

21
Q

how do hematoma look

A

swelling that is bluish red

22
Q

the risk for hemorrhages is greatest during what period?

A

the first 48 hours

requires emergency intervention

23
Q

what do you w/ a external hemorrhage ?

A

reinforce dressings, monitor vitals and notify provider

24
Q

-thick, often malodorous, pus

A

purulent

25
Q

blood; darker red and less watery in appearance

drainage from a surgical drain

A

Sanguineous drainage

26
Q

combination of serous drainage and blood; watery and pink to light red in color

A

Serosanguineous drainage

27
Q

localized collection of blood leaked from adjacent blood cells to organ or tissue

A

Hematoma

28
Q

fluid accumulation containing cell debris

wound fluid comprised of dead cells, serum, bacteria, pus, WBCs

A

Exudate

29
Q

a localized infection

is accumulation of purulent exudate made up of debris from phagocytosis when microorganism have been present

A

abscess

30
Q

inflammation of cellular or connective tissue

subcutaneous

A

cellulitis

31
Q

an abnormal passage or communication usually formed between two internal organ

or leading from an internal organ to the surface of the body

A

fistula

32
Q

is a fistula leading from a purulent exudate-filled CAVITY to the outside of the body

A

sinus

33
Q

what is the best way to prevent wound infections

A

is to maintain strict aseptic technique

34
Q

natural shedding of dead tissue may caused drainage

A

sloughing

35
Q

removal of all foreign or unhealthy tissue from the wound

black wounds

mechanical or chemical removal

A

debridement

36
Q

dead tissue that may be brown to black ;
from

gangrene
burns
pressure
wounds

A

eschar

37
Q

Please describe the process of obtaining a specimen for a wound culture:

A

Pre-procedure & explanation of process

Hygiene and gloves

Remove dressing, discard in biohazard with soiled sides together

cleanse per orders/policy

dispose gloves/hygiene

sterile glove

use swabs from sterile culture tube and insert tip into wound where draining, rotate gently, re-insert swab into culture tube without touching any surface

redress wound with sterile technique

deglove, hand hygiene

transfer labeled sample to lab according to facility policy
