True. The epidermis is avascular and receives nutrients by diffusion from the dermis, which contains the blood vessels, nerves, hair follicles and sweat glands.

Question 2
Thinning of the epidermis and dermis with aging raises the risk of pressure injury.
Correct Answer
True
True. Aging thins the skin layers and may reduce the fatty hypodermis, giving less support over bony prominences, and wounds in older adults also heal more slowly.

Question 3
The phases of wound healing overlap rather than occurring as fully separate steps.
Correct Answer
True
True. Hemostasis, inflammation, proliferation and maturation form an overlapping cascade, so one phase is still underway as the next begins.
Category: Skin and Healing
Question 4
Even a fully remodeled scar does not regain all of the tensile strength of uninjured skin.
Correct Answer
True
True. During maturation, collagen reorganizes and strength increases, but scar tissue never reaches the full strength of the original skin.

Question 5
A moist wound environment supports healing better than letting the wound dry out.
Correct Answer
True
True. Moisture supports growth factors and the multiplication of skin cells, fibroblasts and new vessels, while drying promotes eschar and slows healing; too much moisture, however, macerates the edges.

Question 6
Only pressure injuries should be assigned a pressure injury stage.
Correct Answer
True
True. Staging a wound of another cause, such as a skin tear or burn, with a pressure injury stage legally labels it as a pressure injury, so other wounds are described rather than staged.

Question 7
Hyperbaric oxygen therapy is contraindicated in a patient with an untreated pneumothorax.
Correct Answer
True
True. Pressure changes in the chamber can enlarge trapped air in the chest, so an untreated pneumothorax is the most significant contraindication to treatment.

Question 8
Transparent film dressings cannot absorb drainage, so they suit wounds with little or no exudate.
Correct Answer
True
True. Transparent films let moisture vapor pass but have no absorptive capacity, so they are used on shallow, dry or minimally draining wounds and as cover or securement dressings.

Question 9
A pressure injury on a mucous membrane, such as one caused by a nasogastric tube, cannot be staged.
Correct Answer
True
True. The anatomy of mucous membranes does not match the skin layers used in staging, so mucosal membrane pressure injuries are described but not staged.

Question 10
Debridement turns a stalled chronic wound into an acute wound so that the healing cascade can restart.
Correct Answer
True
True. Removing necrotic tissue, debris and bacteria creates a fresh wound bed, which restarts the orderly healing process in a wound that had stopped progressing.
Category: Wound Bed Care
Question 11
Scab and eschar are two names for the same tissue.
Correct Answer
False
False. A scab is a crust of dried exudate or blood, while eschar is dead, nonviable tissue, so the terms are not interchangeable.
Category: Wound Bed Care
Question 12
Maggot debridement therapy is reserved for small wounds because it is very painful.
Correct Answer
False
False. Sterile fly larvae secrete enzymes that liquefy dead tissue and then ingest it; the method is generally well tolerated and suits large chronic wounds.
Category: Wound Bed Care
Question 13
Collagenase ointment for enzymatic debridement works best when combined with silver dressings.
Correct Answer
False
False. Silver products are not used with collagenase, and the wound must be prepared according to the product's directions for the enzyme to work.
Category: Wound Bed Care
Question 14
Wound odor is assessed before the old dressing is removed and the wound is cleansed.
Correct Answer
False
False. Some odor under a dressing is common, so odor is judged after the dressing is removed and the wound is cleansed; a foul odor that persists after cleansing can indicate infection.
Category: Wound Documentation
Question 15
Comparing a wound's size to a coin is an accepted way to document it.
Correct Answer
False
False. Wounds are measured with a paper or plastic ruler in centimeters, recording length, width and depth, because comparisons to objects are imprecise.
Category: Wound Documentation
Question 16
A wound photograph can replace the nurse's bedside wound assessment.
Correct Answer
False
False. Photographs add a visual record and must follow the facility's protocol, but camera angle, lighting and distance change how a wound looks, so they never replace a bedside assessment.
Category: Wound Documentation
Question 17
Excess adipose tissue improves blood flow to a healing wound.
Correct Answer
False
False. Excess fatty tissue is poorly perfused and impairs blood flow to the wound, while too little fat also delays healing by reducing nutrient and oxygen transport.
Category: Skin and Healing
Question 18
Wound dehiscence occurs most often in incisions on the hands and feet.
Correct Answer
False
False. Dehiscence is most common in abdominal and vascular surgical sites, and obesity, smoking and diabetes raise the risk.
Category: Skin and Healing
Question 19
Dry, cracked skin around a wound suggests that the dressing is holding in too much moisture.
Correct Answer
False
False. Dry, cracked skin indicates too little moisture; skin that is white, soft and wrinkled indicates too much moisture and a dressing that is not managing drainage.
Category: Wound Documentation
Question 20
Cytotoxic antiseptics such as sodium hypochlorite are the preferred routine cleanser for clean, granulating wounds.
Correct Answer
False
False. Clean wounds are cleansed with noncytotoxic solutions such as saline or commercial wound cleansers; cytotoxic antiseptics damage healing cells and are reserved for short-term use in infected or heavily necrotic wounds.
