Q

____, the most common form of skin cancer, grows slowly and rarely metastasizes.

A

Basal cell carcinoma

25
Q

__ __ __ can develop in scar tissue and is also associated with suppression of the immune system. These CANCERS typically appear as firm, skin-colored or red nodules.

A

Squamous cell carcinoma

26
Q

Squamous cell carcinoma usually stays in the ___ but can metastasize

A

epidermis

27
Q

The __ is a common site of metastasis.

A

lower lip

28
Q

___ tends to metastasize, or spread, more easily than the other forms of skin cancer, making it more deadly if not caught early

A

Melanoma

29
Q

3 classifications of melanoma:

A

lentigo maligna melanoma
superficial spreading melanoma
nodular melanoma

30
Q

This black, brown, white, or red pigmented flat lesion occurs predominately on sun-exposed areas of the body. With time, it enlarges and becomes progressively irregularly pigmented. The mean age at diagnosis is 67.

A

lentigo maligna melanoma

31
Q

Most melanomas are of this type. The lesion appears as variable pigmented plaque with an irregular border. It can occur on any area of the body. Its incidence peaks in middle age and continues to be high through the eighth decade.

A

superficial spreading melanoma

32
Q

This melanoma can be found on any body surface and presents as a darkly pigmented papule that increases in size over time

A

nodular melanoma

33
Q

T/F: Age-related changes can weaken the walls of the veins and reduce the veins’ ability to respond to increased venous pressure

A

true

34
Q

Weakened vessel walls cause __ __

A

varicose veins

35
Q

As the poorly nourished legs accumulate debris, inadequately carried away with the venous return, the legs gain a __, __, and __ appearance

A

pigmented, cracked, and exudative

36
Q

An inflammatory condition associated with chronic venous insufficiency. Inflammation of skin due to blood “staying” in one spot. (pooling)

A

Stasis dermatitis

37
Q

These ulcers, known as __ ulcers, often appear on the medial aspect of the tibia above the malleolus and, prior to skin breakdown, present as a dark discoloration of the skin.

A

stasis

38
Q

Any part of the body can develop a pressure injury, but the most common sites are the __, __, and __.

A

sacrum, greater trochanter, and ischial tuberositie

39
Q

Older adults are at high risk for pressure injury because they:

A

Have skin that is fragile and damages easily
Are often in a poor nutritional state
Have reduced sensation of pressure and pain
Are more frequently affected by immobile and edematous conditions, which contribute to skin breakdown

40
Q

Some older patients may develop signs of pressure injuries, even with a turning schedule of every 2 hours, and require more __ __.

A

frequent repositioning

41
Q

Redness of the skin appears quickly and can disappear quickly if pressure is removed

A

Hyperemia.

42
Q

Redness of the skin develops from up to 6 hours of unrelieved pressure and is often accompanied by edema and induration.

A

Ischemia

43
Q

Unremitting pressure extending over 6 hours can cause ulceration with a necrotic base.

A

Necrosis

44
Q

If pressure is not relieved, necrosis will extend through the fascia and potentially to the bone, which is called __ __ __.

A

Deep tissue damage.

45
Q

Reverse staging of a pressure injury should not be done. As the injury heals, refer to it as a “healing stage (whatever number)” and ___

A

state the highest stage at which the injury was assessed to be.

46
Q

Components of physical examination of skin:

A
  • skin surface
  • lesions
  • turgor
  • pressure
  • tolerance
  • temperature
47
Q

Some people are repositioning themselves less than every __ hours

A

2

48
Q

Topical ___ is a treatments for pruritus.

A

Zinc oxide

49
Q

Which is a benign lesion?

Seborrheic keratosis or keratoses?

A

seborrheic keratosis

50
Q

Description of Appearance:

  • small, done-shaped covered by small blood vessels.
  • Resemble small benign flesh-colored moles w/ “pearl” appearance
  • May appear more dark than shiny w. melanin pigments in growth
A

basal cell carcinoma

51
Q

Age-related change: weakened vein walls
Reduce ability of veins to respond to increased venous pressure
Obesity and hereditary factors compound problem

A

vascular lesions

52
Q

Pathophysiology of vascular lesions? (3)

A

varicose veins
lower extremity edema
pigmented appearance

53
Q

PU: A persistent area of skin redness (without a break in the skin) that does not disappear when pressure is relieved
Non-blanchable so normal skin color appears if you push on the ulcer/injury

A

stage 1

54
Q

PU: A partial-thickness loss of skin layers involving the epidermis that presents clinically as an abrasion, blister, or shallow crater

A

stage 2

55
Q

PU: A full thickness of skin is lost extending through the epidermis and exposing the subcutaneous tissues; presents as a deep crater with or without undermining adjacent tissue
Measure depth of this during wound assessment

A

stage 3

56
Q

PU: A full thickness of skin and subcutaneous tissue is lost, exposing muscle, bone, or both; presents as a deep crater that may include necrotic tissue, exudate, sinus tract formation (tunneling), and infection.

A

stage 4

57
Q

PU: Full-thickness loss of tissue with base covered by slough (yellow-mucousy covering on wound) and/or eschar (black unhealthy tissue). Stage cannot be determined until sough or eschar is removed to expose the base and actual depth of wound

A

unstageable

58
Q

PU: Localized area of non-blanchable deep red or purple discoloration with a dark wound bed or blood-filled blister due to intense or prolonged pressure or shearing force. Skin may be intact or non-intact
These are unstageable, bc once the tissue dies and come off, you really don’t know how deep it is and what stage it is with the slough and necrosis on it.

A

deep tissue injury

59
Q

Many patients lose their life to stage __ pressure ulcers if it is not aggressively treated and taken care of

A
