Part 1: Skin Structure & Function (Qs 1-30)
1. Which structure of the skin provides the body with photoprotective
properties by absorbing harmful UV light?
o Answer: B) Melanin
o Rationale: Melanin, produced by melanocytes in the stratum basale,
absorbs UV radiation to protect deeper skin layers from DNA damage.
2. What is the unique function of the layer of the epidermis known as the
stratum basale?
o Answer: B) Producing new epithelial cells
o Rationale: The stratum basale is the reproductive layer of the epidermis,
characterized by proliferating keratinocytes that continuously divide to
produce new epithelial cells.
3. Which cells located in the dermis produce collagen and elastin critical
to immune function and healing?
o Answer: D) Fibroblasts
o Rationale: Fibroblasts are the primary cells in the dermis responsible for
producing collagen, elastin, and extracellular matrix components essential
for wound healing.
4. Which structure of the skin is responsible for providing the body with
photoprotective properties?
, o Answer: B) Melanin.
5. Which epidermal layer is unique to the palms of the hands and the
soles of the feet? (Inferred from original content structure)
o Answer: Stratum lucidum.
6. The "acid mantle" of the skin is an important barrier that helps to:
o Answer: Protect against pathogenic invasion.
7. Which layer of the skin is primarily composed of adipose tissue and
provides insulation and cushioning?
o Answer: Hypodermis (subcutaneous layer).
8. The dermis is composed of two layers; the _______, which is the
superficial layer, and the reticular layer.
o Answer: Papillary layer.
9. Daily bathing is not usually necessary for which patient populations?
o Answer: A) Neonates and elderly
o Rationale: Neonates have immature skin barriers; elderly have reduced
sebaceous activity. Excessive bathing strips protective oils and exacerbates
dryness.
10. Alkaline products should generally be avoided because they
remove protective oils from the skin and alter the protective "acid
mantle."
o Answer: True.
11. Emollients should be applied to damp skin after bathing. The
exact answer is inferred as true from the original content.
12. The outermost layer of the epidermis, responsible for the skin's
water-resistant barrier, is the:
o Answer: Stratum corneum.
13. The primary cell type found in the epidermis is the:
o Answer: Keratinocyte.
