WOCN Wound Exam – Complete Question and Answer
Guide (100% Correct, 2026 Edition)
Introduction:
This comprehensive study resource contains the latest WOCN
(Wound, Ostomy, and Continence Nursing) exam questions and
verified correct answers for 2026. It covers all core areas of wound
care—including pressure injuries, skin integrity, debridement
techniques, support surfaces, infection control, nutrition, perfusion,
neuropathy, and advanced wound therapies such as NPWT and
HBOT. The material also reviews lower extremity ulcers (venous,
arterial, diabetic, vasculitic), wound assessment, and foot and nail
care management. Perfect for students, nurses, and clinicians
preparing for WOCN certification or clinical practice review.
Exam Questions and Answers
What is a constant low pressure support surface? --- correct
answer ---Support surface that provides constant pressure
redistribution
What is immersion? --- correct answer ---Extent to which a patient
can sink into support surface
What is envelopment? --- correct answer ---Extent to which support
surface conforms to patient
,What is an alternating pressure mattress? --- correct answer ---
Support surface with air chambers that alternately inflate and
deflate
How deep must air chambers be for alternating pressure surfaces? -
-- correct answer ---Air chambers must be at least 10cm in depth
What is air fluidized therapy? --- correct answer ---Surfaces that
involve a tank filled wiht siliconized glass beads that create a fluid
medium when air is forced through the beads
Provides very high level immersion and envelopment as well as
high level air flow
What are the issues with air fluidized therapy? --- correct answer --
-difficult to get patient out of bed and difficult to maintain head
elevation
Not for cardio/respiratory issues or tube feedings
What is low air loss? --- correct answer ---low flow of air against
the patient's skin designed to control skin heat and humidity
What is support surface active therapy? --- correct answer ---
powered surface with air chambers that are alternately inflated and
deflated according to defined cycle and not in response to patient's
weight
,What is support surface reactive therapy? --- correct answer ---
surfaces that react to patient's weight by creating comfortable
surface (foam, gel, water bed, air, sheepskin) no change in pressure
points
What are the phases of partial thickness wound repair? --- correct
answer ---1. inflammatory response
2. epithelial cell proliferation and migration
3. reestablishment of normal skin layers and skin thickness
What happens in the partial thickness inflammatory response? ---
correct answer ---24 hours
erythema, edema, serous exudate
What happens in the epithelial cell proliferation and migration
phase of partial thickness wound healing? --- correct answer ---may
begin within 8 hours
Needs attachment of keratinocytes to wound bed and stimulation by
growth factors
How do you promote epithelial cell proliferation? --- correct
answer ---Clean, moist, healthy wound bed
Low bacterial counts
, normal Blood glucose
normal amount of growth factors and MMPs
What occurs in epithelial cell proliferation and migration stage if
there is dermal loss? --- correct answer ---5 days post-injury a
layer of fluid separates epidermis from dermis
Blood vessels sprout
Collagen synthesis begins day 9 to 15 and extends into fluid layer,
new epidermis collapses around new vessels and collagen to form
rete ridges
What happens in the reestablishment of normal skin layers and skin
thickness phase of partial thickness skin repair? --- correct answer
---when migrating epithelial cells make contact, migration ceases
Cells resume upward migration and differentiation
When normal pigmentation is reestablished wound is healed
What are the phases of full thickness wound repair? --- correct
answer ---1. Inflammatory phase: inflammation, hemostasis
2. Proliferative phase: epithelialization, granulation tissue
formation
3. maturation/remodeling
