NSG 100 Exam 3 UPDATED QUESTIONS
AND CORRECT ANSWERS
Functions of the Skin - CORRECT ANSWER 1. protects underlying tissues from
invasion by microorganisms and from trauma
2. nerves in skin enable the perception of touch, pain, pressure, heat and cold
3. assists in regulating temperature
4. supplements the body's intake of vitamin D by synthesizing this vitamin from UV light
epidermis - CORRECT ANSWER outermost layer of skin
-consists of epithelial cells and melanocytes
dermis - CORRECT ANSWER middle layer of skin
- thick layer composed mainly of connective tissue rich in collage and elastin
-stores water, regulates body temperature and production of vitamin D, cushions the body,
and supplies blood to epidermis
-this layer is richly supplied with blood cells, nerve fibers, and lymphatic vessels
-most hair follicles, sebaceous and sweat glands
subcutaneous layer - CORRECT ANSWER "hypodermis"
3rd layer of skin
composed of mainly adipose (fatty) tissues and collage-rich connective tissues
-separates muscle from skin, stores fat, and conserves body heat
infectious skin disorders - CORRECT ANSWER Caused by bacterial, fungal, viral, or
parasitic agents. Examples include impetigo (bacterial), athlete's foot (fungal), chickenpox
(viral), and lice (parasitic).
inflammatory skin disorders - CORRECT ANSWER Caused by pathologies such as
acne, burns, eczema, dermatitis, and psoriasis. Examples include atopic, seborrheic, and stasis
dermatitis.
, neoplastic skin disorder - CORRECT ANSWER Caused by skin cancers. Examples
include squamous cell carcinoma, basal cell carcinoma, and malignant melanoma. Melanoma
is the most serious type of neoplasm
macules - CORRECT ANSWER freckles and flat moles, less than 1 cm wide
papule - CORRECT ANSWER palpable, circumscribed solid elevation of skin
nodule - CORRECT ANSWER palpable, circumscribed deep, firm
ex: wart
tumor - CORRECT ANSWER solid mass
vesicle - CORRECT ANSWER serous fluid filled
ex: blister, herpes simplex
pustule - CORRECT ANSWER pus filled, varies in size
ex: acne
wheal - CORRECT ANSWER palpable, irregular borders
risk factors for impaired skin integrity - CORRECT ANSWER 1. Any patient who is
experiencing decreased mobility, decreased sensory perception, fecal or urinary incontinence,
and/or poor nutrition is at risk for pressure ulcer development
2. Patients with altered sensory perception for pain and pressure are at risk because they
cannot feel their body sensations.
3. Patients who are confused or disoriented or who have alterations in level of consciousness
are unable to protect themselves.
