Dressing Selection
200 Practice Questions with Answers and Rationales
SECTION 1: SKIN ANATOMY & PHYSIOLOGY (Questions 1-45)
1. What are the three primary layers of the skin?
A) Epidermis, dermis, subcutaneous tissue
B) Stratum corneum, stratum basale, dermis
C) Epithelium, connective tissue, muscle
D) Cuticle, corium, hypodermis
Answer: A
Rationale: The skin consists of three primary layers: the epidermis (outermost
layer), the dermis (middle layer containing blood vessels, nerves, and connective
tissue), and the subcutaneous tissue (hypodermis; deepest layer composed of fat
and connective tissue). Understanding these layers is fundamental for wound
assessment and staging pressure injuries .
,2. Which layer of the epidermis is responsible for constant cell renewal and
regeneration?
A) Stratum corneum
B) Stratum granulosum
C) Stratum basale (stratum germinativum)
D) Stratum spinosum
Answer: C
Rationale: The stratum basale is the deepest layer of the epidermis where
keratinocytes undergo mitosis, producing new cells that migrate upward. This
regenerative capacity is critical for wound healing. Damage to this layer affects re-
epithelialization .
3. Which structure of the skin provides the body with photoprotective properties
by absorbing harmful UV light?
A) Melanin
B) Langerhans cells
,C) Odland bodies
D) Stratum lucidum
Answer: A
Rationale: Melanocytes produce melanin, which provides photoprotection by
absorbing UV radiation. This pigment protects the skin from DNA damage caused
by ultraviolet light exposure .
4. Which cells located in the dermis produce collagen and elastin, critical to
wound healing?
A) Leukotrienes
B) Prostaglandins
C) Macrophages
D) Fibroblasts
Answer: D
, Rationale: Fibroblasts are the primary cells in the dermis responsible for
producing collagen and elastin fibers. These proteins provide tensile strength and
elasticity to the skin and are essential for wound healing and scar formation .
5. Which layer of the skin contains blood vessels, nerve endings, and hair follicles?
A) Epidermis
B) Dermis
C) Hypodermis
D) Stratum granulosum
Answer: B
Rationale: The dermis is the middle layer of the skin containing blood vessels,
nerve endings, hair follicles, and connective tissue. It provides structural support
and sensation .
6. What is a unique function of the stratum basale?
A) Providing immunity via Langerhans cells
