Exam 3- Tissue Integrity Flashcards
Integumentary:
Initial reaction to a problem that alters one of the structural components of the skin
Primary
Integumentary:
Changes in the appearance of the primary lesion with progression of an underlying disease or in response to a topical or systemic therapeutic intervention
Secondary
Integumentary:
Related to blood vessel integrity
Vascular
Protects tissues from physical, chemical & biologic damage. Prevents water loss, serves as a water-repellent layer. Stores melanin, converts cholesterol to vitamin D when exposed to sunlight. Contains phagocytes, which prevent bacteria from penetrating skin.
Epidermis
Regulates body temp. by dilating & constricting capillaries.Transmits messages via nerve endings to CNS.
Dermis
Secretes sebum, which lubricates skin & hair & plays role in killing bacteria.
Sebaceous (oil) glands
Regulate body heat by excretion of perspiration.
Eccrine sweat glands.
Remnants of sexual scent gland
Apocrine sweat glands.
A reddening of the skin. May occur during fever, hypertension, inflammation. May also result from sunburns, drug reactions, acne rosacea etc.
Erythema
A bluish discoloration of the skin and mucous membranes.
Cyanosis
Why does cyanosis occur?
Results from poor oxygenation of hemoglobin.
Paleness of skin, may occur with shock, anger, fear, anemia & hypoxia.
Pallor
An abnormal loss of melanin in patches. Typically occurs over the face, hands or groin.
Vitiligo
Appears as patches of pale, itchy wheals in an erythematous area.
Urticaria (hives)
Raised bluish or yellowish vascular lesions.
Bruises (Ecchymosis)
An accumulation of fluid in the body’s tissues.
Edema
How is edema graded?
Depress patient’s skin.
1+ Slight pitting - no obvious distortion
2+ Deeper pit, no obvious distortion
3+ Pit is obvious; extremities are swollen
4+ Pit remains with obvious distortion
When/why is edema commonly found? (think health reasons, not time of day) (5)
- Cardiovascular
- Renal failure
- Trauma
- Cirrhosis of liver
- Side effect of drugs
Hair loss - may be related to hormones, chemical or drug treatments (radiation).
Alopecia

Plaque
Elevated, often reddish area with irregular border caused by diffuse fluid in tissues rather than free fluid in a cavity. Size varies.
Ex. insect bites, hives.
Wheals.
Elevated, solid, hard or soft palpable mass extending deeper into the dermis than a papule. Measure 0.5 to 2 cm.
Ex. small lipoma, intradermal nevi, fibroma.

Tumor
Elevated, pus-filled vesicle or bulla with circumscribed border. Size varies.
Ex. Acne, impetigo, carbuncles.
Pustule
Elevated, encapsulated, fluid-filled or semisolid mass originating from the sub-q tissue or dermis, usually larger than 1 cm.
Ex. sebaceous cyst, epidermoid cyst.
Cyst.
Translucent, dry, paper-like, sometimes wrinkled skin surface resulting from thinning or wasting of the skin due to loss of collagen & elastin.
Ex. Striae, aged skin
Atrophy
Deep, irregularly shaped area of skin loss extending into the dermis or sub-q tissue. May bleed.
Ulcer
Wearing away of the superficial epidermis causing a moist, shallow depression.
Ex. scratch marks, ruptured vesicles.
Erosion
Linear crack with sharp edges, extending into the dermis.
Ex. cracks at corner of mouth, on hands.
Fissure
Rough, thickened, hardened area of epidermis resulting from chronic irritation such as scratching or rubbing.
Lichenification
Flat, irregular area of connective tissue left after a lesion or wound has healed.
Scar
Shedding flakes of greasy, keratinized skjn tissue.
Ex. dandruff, dry skin, psoriasis, eczema.
Scales
Elevated, irregular, darkened area of excess scar tissue caused by collagen formation during healing. Extends beyond the site of the original injury.
Keloid
Dry blood, serum, or pus left on the skin surface when vesicles or pustules burst.
Crust
Benign vascular tumors, come in different forms. Ex. Port wine stain.
Angioma
Raised, reddened round circumscribed plaques covered by silvery white scales.
Psoriasis
Epidermal skin lesion directly related to chronic sun exposure & photodamage.
Actinic keratosis - AKA senile or solar keratosis.
Physical Assessment of Integumentary Includes:
Skin, Hair, Nails
Assessing the skin:
Inspect: Moisture, Vascular changes/markings, Skin Integrity, Hygiene
Palpate: Lesions, Moisture, Temperature, Texture, Turgor
Document lesions: Color, Size, Location, Shape, Texture, Distribution, Drainage, Related findings.
premalignant skin changes related to sun exposure and chronic skin changes
Actinic Keratosis
Most common type of skin cancer but least aggressive, appears on sun-exposed areas of body and incidence increases with age
Basal Cell Carcinomas
- Malignant proliferation of the epidermis, may occur on sun-damaged skin or normal skin
- Can metastasize by blood or lymphatic system, so need to evaluate lymph nodes
- Typically appears as rough, thickened, scaly tumor, common sites are head and face, and upper extremities, may also be nodular
- Treatment – excision, cryosurgery, radiotherapy
Squamous Cell carcinoma
cancerous neoplasm arising from melanocytes, 10 times more likely in fair-skinned individuals, can originate anywhere there is pigment, but 1/3 originate in existing nevi
Malignant Melanoma
Usually > than 6 mm in diameter, are asymmetric, develop within the epidermis over a long period of time ( in-situ)
When they penetrate the dermis can metastasize
Malignant Melanoma
ABCD (and E)rule for assessing suspicious nevi
A – asymmetry (one half of the nevi does not match the other half of the nevi)
B – border irregularity (edges are ragged, blurred, or notched)
C – color variation or dark black color
D – diameter greater than pencil eraser (6 mm)
E – evolving (change in size, shape, color, etc)
The immediate experience of being strengthened by having needs for relief, ease, and transcendence met in four contexts (physical, psychospiritual, social and environmental); much more than the absence of pain
Comfort
Subjective Comfort
Must understand normal for that client. Client’s expression of contentment & ease.
Objective Comfort
Neurological, medical functions, processes typically associated with comfort. Nurse may note vital signs in normal range, calmness in facial expressions.
- The fifth vital sign.
- Unpleasant sensory, emotional experience
- Associated with actual or potential tissue damage
- Described in terms of damage
- Plays protective role
- Relief of pain is a client right
Pain
The most common reason for seeking health care?
Pain
“Whatever the person experiencing it says it is, and existing whenever the person says it does.”
Pain
4 ways to describe pain:
1-location
2-intensity
3-etiology
4-duration
Duration of pain
Establishes difference between acute and chronic pain.
What is used to measure intensity of pain?
A 0-10 pain scale.
Pain scale range:
1-3=
4-6=
7-10=
1-3= mild pain 4-6= moderate pain 7-10= severe pain
Prolonged pain that is constant or recurring for longer than 6 months. May be mild to severe, involves parasympathetic nervous system response.
Chronic pain
Pain that lasts only through the expected recovery period. May be mild to severe, has sympathetic nervous system response.
Acute pain
Pain that may result from direct effects of treatment of this disease…
Cancer pain.
Lack of energy and motivation that may/may not be accompanied by drowsiness

Sleep hygiene
Properly functioning nervous system sends signals that tissues are damaged, requiring attention and proper care.
Physiological pain
Damaged or malfunctioning nerves due to injury, illness or undetermined reasons cause “this” pain.
Neuropathic pain
Sharp and localized or dull & diffuse - pain originating from nerve receptors in the skin or close to body surface.
Somatic pain
Pain that arises from body organs - often radiates or is referred. May be described as cramping, intermittent or colicky pain. Dull achy pain.
Visceral pain
Pain perceived in an area distant from the site of stimuli.
