Part 1: Wound Healing Fundamentals
1. Which phase of wound healing is characterized by
hemostasis and inflammation? A. Proliferative phase B. Maturation
phase C. Hemostatic/Inflammatory phase D. Remodeling phase
Rationale:The hemostatic/inflammatory phase (days 1-5)
involves vasoconstriction, platelet aggregation, clot
formation, and recruitment of inflammatory cells to clear
debris and prevent infection. Answer: C
2. Granulation tissue is primarily composed of: A. Necrotic tissue
and slough B. New blood vessels, fibroblasts, and extracellular matrix C.
Eschar and fibrin D. Epithelial cells only
Rationale:Granulation tissue is the hallmark of the
proliferative phase, consisting of new capillaries
(angiogenesis), fibroblasts producing collagen, and a
provisional matrix that fills the wound bed. Answer: B
3. Which cell type is primarily responsible for collagen
synthesis during wound healing? A. Neutrophils B. Macrophages C.
Fibroblasts D. Keratinocytes
Rationale:Fibroblasts migrate into the wound bed during the
proliferative phase and synthesize collagen (primarily Type
III initially), providing structural integrity to the healing
tissue. Answer: C
,4. The process by which epithelial cells migrate across a
wound bed to restore the epidermal barrier is called: A.
Angiogenesis B. Epithelialization C. Contraction D. Granulation
Rationale:Epithelialization involves keratinocytes migrating
from wound edges or hair follicles across a moist, viable
wound bed to re-establish the epidermal layer. Answer: B
5. Which factor is MOST likely to impair wound healing? A.
Adequate protein intake B. Controlled blood glucose levels C. Smoking
D. Normothermia
Rationale:Smoking causes vasoconstriction, reduces oxygen
delivery, impairs neutrophil function, and delays collagen
synthesis, significantly impairing wound healing. Answer: C
6. A wound that heals by secondary intention: A. Has edges
approximated with sutures B. Is left open to heal from the base upward
C. Heals within 24-48 hours D. Requires skin grafting immediately
Rationale:Secondary intention healing occurs when wound
edges cannot be approximated; the wound fills with
granulation tissue from the base upward and epithelializes
from the edges inward. Answer: B
7. Which vitamin is essential for collagen synthesis and wound
healing? A. Vitamin A B. Vitamin C C. Vitamin D D. Vitamin K
Rationale:Vitamin C (ascorbic acid) is a cofactor for prolyl
and lysyl hydroxylase enzymes required for collagen cross-
linking; deficiency leads to impaired wound healing and
scurvy. Answer: B
8. The "lag phase" of wound healing refers to: A. The time before
epithelialization begins B. The initial 3-5 days when little visible healing
occurs while inflammatory processes prepare the wound C. The period of
wound contraction D. The time after suture removal
Rationale:The lag phase (days 1-5) is when inflammatory cells
clear debris and prepare the wound bed; little visible healing
occurs, but critical biochemical processes are underway.
Answer: B
9. Which cytokine is primarily responsible for stimulating
fibroblast proliferation and collagen production? A. Interleukin-
,1 (IL-1) B. Tumor Necrosis Factor-alpha (TNF-α) C. Transforming
Growth Factor-beta (TGF-β) D. Interferon-gamma (IFN-γ)
Rationale:TGF-β is a key growth factor that stimulates
fibroblast migration, proliferation, and collagen synthesis,
playing a central role in the proliferative phase of healing.
Answer: C
10. Wound contraction is primarily mediated by: A.
Keratinocytes B. Myofibroblasts C. Neutrophils D. Platelets
Rationale:Myofibroblasts, which have characteristics of both
fibroblasts and smooth muscle cells, contract to reduce
wound size during the proliferative phase. Answer: B
Part 2: Wound Assessment & Classification (Questions 11–20)
11. The TIME framework for wound bed preparation stands
for: A. Tissue, Infection/Inflammation, Moisture balance, Edge
advancement B. Temperature, Inspection, Measurement, Evaluation C.
Type, Intensity, Moisture, Exudate D. Tissue, Infection, Moisture,
Epithelialization
Rationale:TIME is a systematic approach: Tissue (debride
non-viable tissue), Infection/Inflammation (control
bioburden), Moisture balance (manage exudate), Edge
advancement (address non-healing edges). Answer: A
12. A Stage 3 pressure injury is characterized by: A. Non-
blanchable erythema of intact skin B. Partial-thickness loss of skin with
exposed dermis C. Full-thickness skin loss with visible subcutaneous fat
but no bone, tendon, or muscle exposed D. Full-thickness skin and tissue
loss with exposed bone, tendon, or muscle
Rationale:Stage 3 pressure injuries involve full-thickness skin
loss where subcutaneous fat may be visible, but bone, tendon,
or muscle are not exposed; slough or eschar may be present.
Answer: C
13. The Braden Scale is used to assess: A. Wound pain levels B.
Risk for developing pressure injuries C. Nutritional status D. Infection
severity
, Rationale:The Braden Scale evaluates six risk factors (sensory
perception, moisture, activity, mobility, nutrition,
friction/shear) to predict pressure injury risk; scores ≤18
indicate risk. Answer: B
14. Which wound characteristic suggests arterial
insufficiency? A. Irregular wound edges with heavy exudate B. Pale
wound bed with minimal bleeding, located on toes or lateral ankle C.
Warm, red, edematous wound with purulent drainage D. Wound with
rolled edges (epibole)
Rationale:Arterial wounds typically appear pale, have
minimal bleeding due to poor perfusion, are often painful,
and are located on distal extremities (toes, lateral ankle,
pressure points). Answer: B
15. The ankle-brachial index (ABI) is used to assess: A. Venous
insufficiency B. Arterial perfusion C. Neuropathy D. Lymphedema
Rationale:ABI compares systolic blood pressure at the ankle to
the brachial artery; values <0.9 suggest arterial disease, 0.9-
1.3 normal, >1.3 suggests non-compressible vessels. Answer: B
16. A diabetic foot ulcer with exposed tendon but no bone
involvement is classified as Wagner Grade: A. Grade 1 B. Grade 2
C. Grade 3 D. Grade 4
Rationale:Wagner Grade 3 ulcers involve deep tissue with
abscess, osteomyelitis, or joint involvement; Grade 2 extends
to tendon, joint capsule, or bone without
abscess/osteomyelitis. Answer: B
17. Which assessment finding is MOST indicative of wound
infection? A. Serous drainage B. Increased pain, erythema, warmth,
purulent drainage, and delayed healing C. Pink granulation tissue D.
Mild maceration of periwound skin
Rationale:Classic signs of infection include increased pain,
erythema, warmth, purulent drainage, foul odor, and failure
to progress; systemic signs may include fever and elevated
WBC. Answer: B
18. The purpose of wound measurement is to: A. Document for
billing only B. Track healing progress and guide treatment decisions C.
Determine patient pain level D. Assess nutritional status
