WOCN WOUND#2 UPDATED EXAM QUESTIONS
WITH 100% VERIFIED ANSWERS
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 - ✔✔ A. Melanin.
Which is a unique function of the layer of the epidermis known as the stratum basale?
A. Providing immunity via Langerhans cells
B. Producing new epithelial cells
C. Releasing lipids to help maintain normal brick and mortar skin configuration
D. Protecting the palms of the hands and soles of the feet - ✔✔B. Producing new
epithelial cells. The stratum basale is the reproductive layer of the epidermis and is
characterized by proliferating keratinocytes.
Which cells located in the dermis produce collagen (dermal building blocks) and elastin
(tensile strength) critical to immune function and healing?
A. Leukotrienes
B. Prostaglandins
C. Macrophages
D. Fibroblasts - ✔✔D. Fibroblasts. Responsible for the synthesis of connective tissue and
extracellular matrix, specifically the production of collagen and elastin.
Which patient's wound would the wound care nurse expect to heal by scar formation?
A. A head wound extending beyond the hair follicles
B. A shallow wound on the hand
C. A stage 2 pressure injury
,D. A first-degree burn - ✔✔A. A head wound extending beyond the hair follicles. The
epidermal appendages, subcutaneous tissue, and muscle do not have the ability to
regenerate, and wounds involving loss of these structures will heal by scar formation.
Which of the following statements accurately describes how the skin functions as a
barrier between the internal and external environments?
A. The skin lipids bind water, normally maintaining skin water content at 20% or higher.
B. When the barrier function of the skin is compromised, transepidermal water loss
(TEWL) decreases.
C. Protection against pathogenic invasion is supported by an acidic pH of skin.
D. Merkel receptors embedded in the extracellular matrix contribute to the mechanical
rigidity and frictional resistance protection of the skin. - ✔✔C. Protection against
pathogenic invasion is supported by an acidic pH of skin. pH of skin is normally 4 -6.5 in
healthy people; this "acid mantle" inhibits pathogenic growth.
The wound care nurse assessing the skin of patients in a nursing home keeps in mind the
structural changes that occur in aging skin. What is one of these changes?
A. Increase in melanocytes
B. Rounding of dermal-epidermal junction
C. Increase in mast cells
D. Decrease in collagen - ✔✔D. Decrease in collagen. Intrinsic aging refers to the
physiologic changes to the skin cells and tissues that take place with time and are
impacted by genetic hormonal factors. These changes include decreased collagen
production, decreased blood flow to the skin, and lower amounts of lipids.
The wound care nurse uses the acronym ABCDE to distinguish a melanoma from a
benign nevus. Based on this acronym, what is a distinguishing characteristic of
melanoma?
A. Regular border
B. Consistent red or black color
C. Diameter >4 mm
D. Evolving lesion - ✔✔ D. Evolving lesion. Asymmetry, irregular border, variable and
uneven color, diameter > 6 mm, evolving lesion.
,On which body site would the transdermal application of a medication obtai n the greatest
percutaneous absorption?
A. Plantar surface of the foot
B. Forearm
C. Forehead
D. Hand - ✔✔C. Forehead. Current data indicate that one can crudely rank the regional
permeability as follows: nail << palm/sole << trunk/extremities << face/scal p << scrotum.
As part of the face, the forehead would be the most permeable of the choices for both
sexes.
Which principle of skin care product use would the wound care nurse include in a
teaching plan for a patient with a leg wound?
A. Use alkaline soaps and cleansers to neutralize acidic skin.
B. Do not use products on the skin that have known sensitizers.
C. Bathe frequently using water that is as hot as tolerated.
D. Allow skin to dry completely before applying moisturizer. - ✔✔B. Do not use products
on the skin that have known sensitizers. Important to use products on the skin that have
ingredients that are known sensitizers (likely to cause allergic reactions).
Which layer of skin contains cells that release lipids such as ceramides to maintain the
normal "brick and mortar" skin barrier function.
A. Stratum germinativum
B. Stratum basale
C. Stratum spinosum
D. Stratum granulosum - ✔✔D. Stratum granulosum. Keratinocytes in the stratum
granulosum layer release lipids including ceramide lipids that help maintain the normal
brick and mortar skin barrier function. The stratum granulosum cells also contain
glycolipids that when released, function to act as a glue, holding the cells together.
The incision of a postop cardiac surgery patient is in the inflammatory phase of wound
healing. What is one mechanism of healing occurring in this phase?
, A. Neutrophils and monocytes are chemoattracted to the wounded area.
B. Fibroblasts migrate to the area in response to cellular signaling.
C. A new extracellular matrix (granular tissue) is formed.
D. Cells responsible for collagen synthesis and angiogenesis undergo apoptosis. - ✔✔A.
Neutrophils and monocytes are chemoattracted to the wounded area.
The wound care nurse is explaining the phases of wound healing to a pateint who has a
sutured laceration. Which statement accurately describes the typical time frame for
proliferation to occur?
A. 1-2 days
B. 3-5 days
C. 21-30 days
D. 1-2 years - ✔✔C. 21-30 days. Proliferation begins at day 1 postinjury and is typically
complete by days 21-30.
A patient has a full-thickness pressure injury on the back of the head. What order of
healing would occur with this wound?
A. Epithelial resurfacing - granulation tissue formation
B. Reepithelialization - granulation tissue formation - remodeling
C. Epithelial resurfacing - granulation tissue
D. Inflammatory phase - granulation tissue formation - epithelial resurfacing -
remodeling - ✔✔D. Inflammatory phase - granulation tissue formation - epithelial
resurfacing - remodeling. The "order of repair" for an open wound healing by secondary
intention (sometimes prolonged) is a inflammatory phase, then granulation tissue
formation followed by epithelial resurfacing, and finally remodeling.
What process is the foundation of modern wound care and is essential for maintenance of
cellular viability and cell migration?
A. Dry wound preparation
B. Moist wound healing
C. Antibacterial soaks
