Question 9

Purposes

Answer 9

To protect the wound from mechanical injury
To protect the wound from microbial contamination
To provide or maintain moist wound healing
To provide thermal insulation
To absorb drainage or debride a wound or both
To prevent hemorrhage (when applied as a pressure dressing or with elastic bandages)
To splint or immobilize the wound site and thereby facilitate healing and prevent injury.

Question 10

Type of dressing used depends on

Answer 10

(a) the location, size, and type of the wound
(b) the amount of exudate
(c) whether the wound requires debridement or is infected
(d) such considerations as frequency of dressing change, ease or difficulty of dressing application, and cost

Question 11

Types of dressings

Answer 11

Dry dressings
Wet to dry dressings
Wet to wet dressings

Question 12

Used primarily for wounds closing by primary intention. Offers good wound protection, absorption of drainage, and aesthetics for the patient and provides pressure, if needed, for
hemostasis

Answer 12

Dry dressings

Question 13

Dry dressing disadvantage

Answer 13

they adhere to the wound surface when drainage dries. (Removal can cause pain and disruption of granulation tissue.)

Question 14

These are particularly useful for untidy or infected wounds that must be debrided and closed by secondary intention.

Answer 14

Wet to dry dressings

Question 15

Used on clean open wounds or on granulating surfaces. Sterile saline or an antimicrobial agent may be used to saturate the dressings.

Provides a more physiologic environment (warmth, moisture), which can enhance the local healing processes as well as ensure greater patient comfort. Thick exudate is more easily removed.

Answer 15

Wet to wet dressings

Question 16

Wet to wet dressings disadvantage

Answer 16

surrounding tissues can become macerated,
there is an increased risk for infection, and bed linens become damp.
