What is the primary therapeutic mechanism of compression therapy in venous leg ulcer management?
Answer: Counteracting venous hypertension by promoting venous return and reducing edema
Compression therapy directly addresses the underlying pathophysiology by countering venous hypertension, improving venous return, and reducing edema that impairs wound healing.
Red blood cells are made of a protein that gives them their red color and their capacity to carry oxygen. What is the name of this protein?
Answer: Hemoglobin
Hemoglobin is the iron-containing protein found within red blood cells. It is responsible for binding to and transporting oxygen from the lungs to the body's tissues. The iron component of hemoglobin is also what gives red blood cells and blood its characteristic red color.
What does the term 'epithelialization' refer to in wound healing?
Answer: Migration of epithelial cells from wound edges to resurface the wound
Epithelialization is the process by which epithelial cells migrate across the wound surface to restore the protective skin barrier, occurring as the final step of healing.
After surgery or injury, what is a collection of extravasated blood stuck in tissues or organs?
Answer: Hematoma
A hematoma is a localized collection of blood outside of blood vessels, typically clotted, within tissues or organs, often resulting from trauma or surgery. It forms when blood escapes from damaged vessels and accumulates, appearing as a bruise or swelling, and is distinct from conditions like cellulitis or evisceration.
The skin layer that lies between the stratum corneum and the stratum granulosum is known as the _________ . It is made up of translucent cells that are exclusively found on the soles of the feet and the palms of the hands.
Answer: Stratum lucidum
The stratum lucidum is a thin, clear, and translucent layer of dead skin cells found exclusively in the thick skin of the palms of the hands and soles of the feet. It is located between the stratum corneum and the stratum granulosum. This layer provides an additional protective barrier in areas subjected to high friction and pressure.
What Is a Keloid?
Answer: Overgrowth of a collagenous scar tissue at the site of the wound.
A keloid is an abnormal, raised scar that develops at the site of a skin injury, but it extends beyond the original boundaries of the wound. It results from an overproduction of collagen during the healing process, leading to a firm, rubbery, and often itchy or painful growth that is distinct from a hypertrophic scar which stays within the wound margins.
A patient with a chronic venous ulcer has been on long-term, high-dose corticosteroid therapy for an autoimmune condition. Which phase of wound healing is MOST significantly impaired by this medication?
Answer: Inflammatory phase
Corticosteroids are potent anti-inflammatory agents that suppress the initial inflammatory response crucial for healing. They inhibit the migration and function of key immune cells like neutrophils and macrophages, which are essential for clearing debris and signaling the start of the repair process.
When taking steps to avoid friction that could lead to a pressure ulcer, which of the following should be avoided?
Answer: Talcum powder
Talcum powder should be avoided in areas prone to friction and pressure ulcers. It can clump, absorb moisture, and create abrasive particles that increase friction and shear forces on the skin. This can irritate the skin and contribute to skin breakdown, rather than preventing pressure ulcer formation.
What is the best dressing to use when a deep ulcerated area has a lot of exudate and the drainage is caused by tumor necrosis?
Answer: Alginate
Alginate dressings are highly absorbent, making them the best choice for deep, highly exudative wounds, especially those with significant drainage from tumor necrosis. Made from seaweed, alginates form a gel upon contact with wound exudate, which helps to manage moisture, promote autolytic debridement, and conform to the wound bed, creating an optimal healing environment.
Total contact casting (TCC) is considered the gold standard offloading device for plantar diabetic neuropathic ulcers because it:
Answer: Redistributes plantar pressure over the entire foot and lower leg surface
TCC redistributes plantar pressure over the entire plantar foot and lower leg, dramatically reducing focal pressure at the ulcer site and achieving the highest documented healing rates.
What is the separation of one or more layers of a wound caused by too much pressure on a wound that hasn't healed? Muscles are usually intact in this state.
Answer: Dehiscence
Dehiscence is the partial or complete separation of the layers of a surgical wound, often occurring due to excessive tension or inadequate healing. In this state, the superficial layers of the wound open, but the deeper structures, such as muscles, typically remain intact. Evisceration is a more severe complication where internal organs protrude through the wound opening.
What is the appropriate management IMMEDIATELY after sharp debridement of a wound?
Answer: Apply appropriate moist wound dressing and reassess for bleeding
After sharp debridement, a moist wound dressing appropriate for the wound status should be applied while monitoring for and controlling bleeding.
What is the shortest amount of time that an EMLA cream (Eutectic Mixture of Local Anesthetics) should be applied before initiating a dressing change in order to relieve pain?
Answer: 60 minutes
EMLA cream, a topical anesthetic, requires sufficient time to penetrate the skin layers and effectively numb the nerve endings. For optimal pain relief during procedures like dressing changes, it is generally recommended to apply the cream for at least 60 minutes (1 hour) before initiating the intervention. This ensures adequate absorption and therapeutic effect, minimizing patient discomfort.
Which of the following is a PRIMARY indication for collagen dressings?
Answer: Stalled or non-healing chronic wounds to stimulate granulation
Collagen dressings provide extracellular matrix scaffolding and growth factors that help stimulate granulation in stalled chronic wounds.
The word "slough" is used to describe a wound and means:
Answer: a soft viscous yellow layer of necrotic tissue that covers and adheres to the wound
The term 'slough' in wound care describes a soft, viscous, yellow or tan layer of necrotic tissue that covers and adheres to the wound bed. It consists of dead cells, fibrin, and exudate. Slough must be removed, often through debridement, for the wound to progress to healing.
A fistula is best defined as:
Answer: An abnormal opening between two epithelium-lined organs or surfaces
A fistula is an abnormal communication between two epithelialized surfaces, such as an enteric-cutaneous fistula.
Which type of tissue should generally NOT be debrided in heel wounds?
Answer: Stable, dry, adherent eschar without signs of infection
Stable, dry, adherent eschar on heel wounds without infection or fluctuance should not be debrided, as it serves as a biological cover protecting underlying tissue.
Which pH range is considered optimal for wound healing and proteolytic enzyme activity in a healing wound bed?
Answer: pH 5.5–6.5
A slightly acidic wound pH of 5.5–6.5 supports optimal healing by promoting oxygen release and inhibiting bacterial growth.
Which compression system is considered the gold standard for venous leg ulcer treatment?
Answer: Four-layer compression bandage system (Charing Cross regimen)
The four-layer compression bandage system delivers sustained 40 mmHg compression at the ankle and has the strongest evidence base for venous leg ulcer healing.
Which of the following nutritional recommendations is MOST important for an individual at high risk for pressure injury development?
Answer: Increased fluid intake and adequate protein.
Adequate hydration is crucial for maintaining skin turgor and perfusion, while sufficient protein is essential for tissue repair and maintenance. International guidelines emphasize ensuring adequate intake of fluid and protein as key nutritional interventions for pressure injury prevention.
