Which debridement method uses the body's own enzymes and moisture to remove necrotic tissue?
Autolytic debridement
Mechanical debridement
Enzymatic debridement
Surgical debridement
Autolytic debridement uses endogenous enzymes and moisture from dressings to soften and liquefy necrotic tissue. It is painless and selective for dead tissue. Other methods rely on external agents or instruments.
Which debridement method involves physical removal of debris by techniques like wet-to-dry dressings or irrigation?
Mechanical debridement
Autolytic debridement
Enzymatic debridement
Biological debridement
Mechanical debridement physically disrupts and removes devitalized tissue through irrigation, wet-to-dry dressings, or scrubbing. It is non-selective and may damage healthy tissue. Other methods use biological or chemical processes.
Which patient factor most significantly impairs wound healing by reducing collagen synthesis and neovascularization?
Diabetes mellitus
Advanced age
Mild obesity
Moderate exercise
Diabetes mellitus impairs collagen synthesis, reduces neovascularization, and increases infection risk due to hyperglycemia. Age and obesity have an effect but less directly on collagen and vessels. Exercise generally supports healing.
What is an essential safety protocol to minimize infection during debridement?
Wearing sterile gloves and using sterile instruments
Applying ointment before cleaning
Measuring wound size repeatedly
Using non-sterile dressings first
Sterile gloves and instruments prevent introduction of pathogens into the wound bed during debridement. Measuring or applying ointment does not directly control infection risk. Non-sterile dressings increase contamination.
Which tissue type appears as red, moist tissue that indicates new blood vessel formation?
Granulation tissue
Slough
Eschar
Necrotic tissue
Granulation tissue is red and moist, reflecting healthy capillary growth. Slough is yellow or white, eschar is black or brown, and necrotic tissue is dead and unhealthy.
What is the mechanism of action of collagenase in enzymatic debridement?
Breaking down necrotic collagen in the wound bed
Dissolving healthy granulation tissue
Lysing bacterial cell walls
Hydrating the wound bed
Collagenase selectively hydrolyzes necrotic collagen, aiding removal of devitalized tissue. It spares healthy tissue when used correctly. It does not target bacteria or normal ECM.
In a patient with high bleeding risk and painful wounds, which debridement method is most appropriate?
Autolytic debridement
Surgical debridement
Mechanical debridement
Sharp debridement
Autolytic debridement is gentle and virtually painless, reducing bleeding risk by using the body's own enzymes. Surgical or sharp methods carry higher bleeding and pain risk.
In the TIME framework for wound bed preparation, what does 'M' represent?
Moisture balance
Microbial control
Mechanical cleaning
Margin assessment
In TIME, M stands for moisture balance, ensuring the wound is neither too wet nor too dry. This optimizes healing. Other letters address tissue, infection, and edge advancement.
A wound bed is covered with black, hard, leathery tissue. What is the correct term?
Eschar
Granulation
Slough
Epibole
Eschar is black, dry, and leathery necrotic tissue. Slough is yellow or white and moist. Granulation is red and vascular. Epibole refers to rolled wound edges.
Which debridement technique uses low-frequency ultrasound to selectively remove necrotic tissue?
Ultrasonic debridement
Pulsed lavage
Maggot therapy
Enzymatic debridement
Ultrasonic debridement uses low-frequency ultrasound waves to emulsify necrotic tissue while preserving healthy tissue. Pulsed lavage uses pressurized fluid, and maggots are biological.
Excessive wound moisture often leads to which complication?
Hypergranulation tissue
Eschar formation
Delayed onset of granulation
Immediate re-epithelialization
Excessive moisture can cause hypergranulation, where tissue grows above the wound surface. Eschar is dry necrosis, and re-epithelialization is inhibited by too much fluid.
According to infection control standards, sharp debridement instruments must be sterilized using which method?
Autoclaving
Chemical wiping only
Ultraviolet light
Dry heat at room temperature
Autoclaving uses pressurized steam to achieve sterility and is standard for sharp instruments. Chemical wiping and UV light are insufficient for complete sterilization.
Enzymatic debridement is contraindicated in wounds that contain:
Healthy granulation tissue
Thick necrotic eschar
Adherent slough
Infected necrotic tissue
Enzymatic agents can damage healthy granulation tissue, so they are avoided in wounds with viable tissue. They are indicated for necrotic or slough-covered wounds.
Yellowish, soft, moist tissue on the wound bed is termed:
Slough
Eschar
Granulation tissue
Keratin
Slough is yellow or cream-colored and moist, representing dead fibrin and cells. Eschar is black or brown and leathery. Granulation tissue is red.
What is the primary goal of wound bed preparation?
Remove barriers to healing and optimize the wound environment
Increase pain to signal healing
Prevent any dressing changes
Maximize necrotic tissue retention
Wound bed preparation focuses on removing devitalized tissue, controlling infection, and balancing moisture to foster healing. Retaining necrosis or preventing care impedes this process.
A 65-year-old with a diabetic foot ulcer has extensive necrosis and suspected osteomyelitis. Which debridement is most urgent?
Surgical/sharp debridement
Autolytic debridement
Enzymatic debridement
Mechanical irrigation
Extensive necrosis and osteomyelitis require prompt surgical debridement to remove devitalized tissue and reduce infection risk. Other methods are too slow for this scenario.
A venous leg ulcer with a thick, adherent fibrinous layer and moderate exudate is best managed initially by:
Enzymatic debridement
Surgical debridement
Autolytic debridement
Maggot therapy
Enzymatic debridement is effective for thick fibrinous slough in a moderately exuding venous ulcer and is faster than autolytic methods. Surgical is more invasive.
Sharp debridement is contraindicated in which circumstance?
Uncontrolled bleeding disorder
Presence of necrotic eschar
Adherent slough on wound bed
High bacterial load
Sharp debridement can trigger severe bleeding in patients with uncontrolled coagulopathy. Necrotic or slough tissue and bacterial load alone are not absolute contraindications.
Which statement best describes how maggot therapy debrides wounds?
Larvae secrete proteolytic enzymes that liquefy necrotic tissue
Maggots physically scrape only healthy tissue
Maggots release antibiotics into the wound
They raise wound pH above physiological levels
Maggots excrete proteolytic enzymes that digest necrotic tissue into a liquid form which they then ingest, sparing healthy tissue. They do not produce antibiotics or significantly alter pH.
A wound shows high bacterial bioburden but no clinical infection signs. According to the TIME framework, what is the next best step?
Use antimicrobial dressings to reduce bioburden
Perform immediate surgical debridement
Avoid any dressing changes
Rely solely on systemic antibiotics
Increased bioburden without infection signs calls for antimicrobial dressings under the Infection control aspect of TIME. Immediate surgery or systemic antibiotics are not indicated absent infection.
