## Part I: Skin, Hair, and Nail Assessment (35 Questions)
### Topic A: Anatomy & Physiology of the Skin
**Question 1**
The nurse educator is preparing a module on the epidermal layer. Which
statement should be included?
a) Highly vascular and sensitive.
b) Thick and tough like leather.
c) Thin and nonstratified.
d) **Replaced every 4 weeks.**
,2|Page
**Rationale:** The epidermis is avascular and stratified squamous
epithelium. It regenerates approximately every 4 weeks (28 days). The
dermis is vascular and contains sensory receptors.
**Question 2**
A patient says, "I sweat a lot on my face and feet, but it doesn't have an
odor." This is related to which glands?
a) **Eccrine glands**
b) Apocrine glands
c) Sebaceous glands
d) Ceruminous glands
**Rationale:** Eccrine glands produce dilute, odorless sweat for
thermoregulation and are found on palms, soles, forehead. Apocrine
glands (axillae, groin) produce odor when broken down by bacteria.
**Question 3**
The dermis layer differs from the epidermis because it:
a) Is avascular.
b) Is replaced every 4 weeks.
c) **Contains sensory receptors.**
d) Consists mostly of keratin.
,3|Page
**Rationale:** The dermis contains blood vessels, nerves, and sensory
receptors (Meissner's corpuscles for touch, Pacinian corpuscles for
pressure). The epidermis is avascular and keratinized.
**Question 4**
A 75-year-old patient has wrinkled, lax, dry skin. This is related to:
a) Increased elastin and increased subcutaneous fat.
b) Increased vascularity of the skin.
c) **Increased loss of elastin and decrease in subcutaneous fat.**
d) Increased numbers of sweat glands.
**Rationale:** Aging causes loss of elastin (leading to wrinkles) and
atrophy of subcutaneous fat (leading to laxity). Sebaceous gland activity
also decreases, contributing to dryness.
**Question 5**
An older adult's hair looks gray/white and feels thin. This occurs due to
a decrease in:
a) Keratinocytes.
b) **Melanocytes.**
c) Sebaceous glands.
d) Apocrine glands.
, 4|Page
**Rationale:** Gray hair results from a reduction in melanocyte
function (melanin production), not necessarily the number of hairs. Hair
thinning occurs from decreased hair follicle activity.
**Question 6**
Which layer of the skin contains the hair follicles and sebaceous glands?
a) Epidermis
b) **Dermis**
c) Subcutaneous tissue
d) Stratum corneum
**Rationale:** The dermis contains all skin appendages: hair follicles,
sebaceous glands, and sweat glands. The epidermis is only epithelial
cells.
**Question 7**
A patient has decreased skin turgor. This indicates:
a) **Dehydration**
b) Hyperthyroidism
c) Increased subcutaneous fat
d) Normal aging without pathology
