Q1. A wound care specialist is reviewing the structure of the skin with a new clinician. Which layer of
the skin contains the blood vessels, nerve endings, hair follicles, and sweat glands?
A. Epidermis
B. Dermis
C. Subcutaneous tissue
D. Fascia
Correct Answer: B
Rationale: The dermis is the second and middle layer of the skin, and it contains the blood
vessels, nerve endings, hair follicles, sebaceous glands, and sweat glands that support skin function
and sensation. The epidermis is the outermost avascular layer and contains no blood vessels. The
subcutaneous tissue lies beneath the dermis and consists primarily of fat and connective tissue.
Fascia is a deeper fibrous layer that surrounds muscles and organs. Understanding which structures
reside in each skin layer is essential for wound assessment because the depth of tissue destruction
determines wound staging, healing potential, and appropriate dressing selection.
,Q2. A clinician is assessing a patient with a suspected deep tissue injury. Which structure is primarily
affected in a deep tissue injury?
A. Epidermis only
B. Dermis only
C. Muscle and bone
D. Subcutaneous tissue and underlying muscle
Correct Answer: D
Rationale: A deep tissue injury involves damage to the subcutaneous tissue and underlying
muscle while the skin surface may remain intact or appear discolored. The epidermis and dermis may
appear less affected on the surface, which is why deep tissue injuries are often underestimated.
Muscle and bone involvement typically indicates a more advanced stage of pressure injury or a
deeper wound category. Recognizing the depth of tissue involvement is critical because deep tissue
injuries can deteriorate rapidly and require aggressive offloading, close monitoring, and appropriate
support surfaces.
Q3. A wound care specialist is explaining the function of the epidermis. Which of the following is a
primary function of the epidermis?
A. Providing a barrier against environmental hazards
B. Producing collagen and elastin
C. Supplying blood to the dermis
D. Storing fat for energy
Correct Answer: A
Rationale: The epidermis serves as the body's primary barrier against environmental hazards
such as bacteria, chemicals, ultraviolet radiation, and mechanical trauma. Collagen and elastin
production occurs primarily in the dermis. The epidermis is avascular and does not supply blood to
the dermis. Fat storage occurs in the subcutaneous tissue. Understanding the barrier function of the
epidermis helps wound care specialists recognize that disruption of this layer increases infection risk
and fluid loss, which guides decisions about protective dressings and topical therapy.
Q4. A wound care specialist is reviewing the phases of wound healing. Which phase is characterized
by hemostasis and inflammation?
A. Proliferative phase
B. Maturation phase
C. Inflammatory phase
D. Remodeling phase
,Correct Answer: C
Rationale: The inflammatory phase begins immediately after injury and includes hemostasis,
vasoconstriction, platelet aggregation, and the release of inflammatory mediators. The proliferative
phase follows and involves granulation tissue formation, angiogenesis, and epithelialization. The
maturation or remodeling phase is the final phase and involves collagen reorganization and scar
maturation. Recognizing the sequence of wound healing phases allows clinicians to anticipate
expected wound appearance and to identify when healing is delayed or stalled.
Q5. A wound care specialist is evaluating a wound that is failing to heal. Which factor most
commonly contributes to impaired wound healing?
A. Adequate nutrition
B. Uncontrolled diabetes
C. Regular exercise
D. Adequate hydration
Correct Answer: B
Rationale: Uncontrolled diabetes impairs wound healing through multiple mechanisms,
including poor perfusion from microvascular disease, impaired leukocyte function, neuropathy, and
altered collagen synthesis. Adequate nutrition, regular exercise, and adequate hydration all support
wound healing rather than impair it. Identifying systemic factors such as diabetes, vascular disease,
and immunosuppression is essential because local wound care alone will not heal a wound when
underlying systemic conditions are not optimized.
Q6. A wound care specialist is reviewing the anatomy of the skin. Which layer is avascular and
depends on the dermis for nutrition?
A. Epidermis
B. Dermis
C. Subcutaneous tissue
D. Muscle
Correct Answer: A
Rationale: The epidermis is avascular and receives nutrition by diffusion from the capillaries in
the dermis beneath it. The dermis is highly vascular and contains the capillary networks that nourish
the epidermis. The subcutaneous tissue contains fat and larger vessels, and muscle has its own
extensive vascular supply. Understanding that the epidermis depends on dermal diffusion explains
why dermal injury can compromise epidermal viability and why wounds involving the dermis require
careful management to support healing.
, Q7. A wound care specialist is assessing a wound and notes the presence of slough. What does
slough most likely represent?
A. Healthy granulation tissue
B. Devitalized tissue
C. Epithelial tissue
D. Subcutaneous fat
Correct Answer: B
Rationale: Slough is devitalized, yellow or gray fibrous tissue that is often a mixture of fibrin,
bacteria, and inflammatory cells. It can impede healing by creating a barrier to granulation and
epithelialization. Healthy granulation tissue appears red, moist, and granular. Epithelial tissue is pale
and new. Subcutaneous fat appears as yellow lobules that may resemble slough but is distinct in
texture and structure. Correctly identifying slough guides the decision to debride and to select
dressings that promote autolytic debridement.
Q8. A wound care specialist is reviewing the vascular supply of the lower extremity. Which artery is
most commonly assessed when evaluating for peripheral arterial disease in the lower leg?
A. Dorsalis pedis artery
B. Radial artery
C. Brachial artery
D. Carotid artery
Correct Answer: A
Rationale: The dorsalis pedis artery and the posterior tibial artery are the two pulses most
commonly palpated when assessing for peripheral arterial disease in the lower extremity. The radial
and brachial arteries are upper extremity pulses, and the carotid artery supplies the head and neck.
Palpating these pedal pulses and calculating the ankle-brachial index are essential components of
lower extremity wound assessment because arterial insufficiency can prevent healing and
contraindicate compression therapy.
Q9. A wound care specialist is reviewing the physiology of wound healing. Which cell type is primarily
responsible for collagen synthesis during the proliferative phase?
A. Neutrophils
B. Macrophages
C. Fibroblasts
D. Platelets
Correct Answer: C
