NURS 330 Final Exam 2 Questions And
Revised Answers.
remodeling phase - Answer new collagen @ max, macrophages stimulate gradual replacement of new,
rapidly replaced collagen with mature collagen. Increases tensile strength of wound. This phase can last
up to 2 years
proliferative phase - Answer fibroblasts migrate to wound bed, deposit collagen, secrete growth
factors. Macrophages produce enzymes to stimulate tissue growth and generate blood vessels.
Granulation appears, edges begin to contract. Epithelial growth closes the defect. This phase can last up
to 4 weeks.
inflammatory phase - Answer polymorphonuclear cells cleanse and kill bacteria on wound.
Mononuclear cells follow and become macrophages to further cleanse the wound. This phase can last 2-
3 days.
molluscum contagiosum - Answer a pox virus that produces waxy, umbilicated, keratinized lesions on
the skin, and rarely, the conjunctiva or mucous membranes. Spread by direct contact with
immunocompetent people.
pityriasis rosea - Answer begins with a single large macular lesion on the trunk, progresses to multiple
macular lesions in a Christmas tree pattern predominantly over the chest and back
atrophy - Answer thinning of skin from loss of skin structures
keloid - Answer excessive fibrous tissue replacement, resulting in enlarged scar and deformity. Tough,
elevated, irregularly shaped scars. Usually have smooth top, are pink and purple, enlarge when healing,
and do not shrink like a normal scar. Common in African Americans
varicella rash - Answer begins with macular lesions, progresses to papular, then vesicular, and
ultimately superficial ulcers
, erosion - Answer loss of epidermal layer, usually not extending into dermis or subcutaneous layer.
Examples: aphthous stomatitis, varicella
scale - Answer rapid turnover of epidural layer, resulting in accumulation and delayed shedding of
outermost epidermis. Examples: psoriasis, tinea corpis
pustule - Answer purulent, fluid-filled, raised of any size. Examples: pustular acne, folliculitis
lichenification - Answer accentuation of normal skin lines resembling tree bark, commonly caused by
excessive scratching. Examples: lichen simplex chronicus, psoriasis, chronic contact dermatitis
csyt - Answer distinct and walled-off, containing fluid or semi-solid material, varies in size
bulla - Answer fluid filled < 1cm in diameter. Examples: partial thickness burns, bullus impetigo
macule - Answer flat, circumscribed, discolored, < 1cm. Example: freckles, tattoo, stork bite
papule - Answer raised, defined, < 1cm in diameter. Example: wart, insect bite, molluscum contagiosum
plaque - Answer raised, defined, any color, > 1cm diameter. Examples: psoriasis, lichen sclerosis
vescile - Answer fluid filled, < 1cm in diameter. Examples: herpes simplex, chicken pox
dermis - Answer contains blood vessels, nerves, sebaceous glands, lymphatic vessels, hair follicles, and
sweat glands
eccrine and apocrine - Answer 2 types of sweat glands
epidermis - Answer outer layer, 1st line of skin's defense against pathogens, chemical irritants, and
moisture loss
