Q

What is primary intention?

A

A process that closes the edges of a wound with little or no inflammatory reaction (little or no scar)

68
Q

What is secondary intention?

Healing by granulation or indirect union

- granulation tissue is formed to fill the gap between the edges of the wound with a thin layer of fibrinous exudate

69
Q

What is tertiary intention?

A

Delayed wound healing

  • occurs in the base of ulcerated or cavitary wound
  • especially after infection
  • wound fills very slowly with granulation tissue and often forms a large scar

Q

What is a hematoma?

A

A solid swelling of clotted blood within the tissues

71
Q

What is dehiscence?

A

Wound ruptures along a surgical incision

72
Q

What is evisceration?

A

Protrusion of the internal organs through an incision

73
Q

What is a fistula formation?

A

An abnormal tube-like passage from a normal cavity or tube to a free surface or to another cavity

74
Q

What is a partial-thickness wound?

A

Shallow and involve the loss of the epidermis and partial loss of the dermis

75
Q

What is a full thickness wound?

A

Extend into the dermis and heal by scar formation

76
Q

If you had to clean an incision site, a penrose drain, and a nephrostomy tube, what order would you clean them in?

A
  1. Incision site
  2. Nephrostomy tube
  3. Penrose drain
77
Q

What is a Penrose drain?

A

A Penrose drain is a surgical device, placed in a wound to drain fluid.
- It consists of a soft rubber tube placed in a wound area, to prevent the build up of fluid
