Wound Care Certification Exam Wound Care Certification Beginner's Guide 5 — Questions and Answers
Question 1: Which of the following best describes a 'biofilm' in chronic wound management?
- A thin transparent film dressing applied to wounds
- An organized community of bacteria encased in a protective polysaccharide matrix (Correct answer)
- A superficial skin infection limited to the epidermis
- A type of enzymatic debridement agent
Correct answer: An organized community of bacteria encased in a protective polysaccharide matrix
Biofilm is a structured community of microorganisms embedded in a self-produced matrix that protects bacteria from antibiotics and host immune defenses, contributing to chronic wound stalling.
Question 2: A wound that heals by 'secondary intention' is best described as:
- A wound closed primarily with sutures immediately after injury
- A wound left open to heal through granulation, contraction, and epithelialization (Correct answer)
- A wound closed after a delay of 3–5 days
- A wound covered with a skin graft
Correct answer: A wound left open to heal through granulation, contraction, and epithelialization
Secondary intention healing occurs when wound edges are not approximated and the wound fills from the base up with granulation tissue before epithelialization covers the surface.
Question 3: Which laboratory value is most useful for assessing a patient's overall nutritional status and its impact on wound healing?
- Fasting blood glucose
- Serum albumin or pre-albumin (Correct answer)
- Complete blood count with differential
- Erythrocyte sedimentation rate
Correct answer: Serum albumin or pre-albumin
Serum pre-albumin (with a shorter half-life of ~2 days) and albumin are commonly used markers of protein status and can reflect nutritional adequacy for wound healing.
Question 4: A wound care specialist selects a silver-containing dressing for a wound. What is the primary purpose of silver in wound dressings?
- To stimulate granulation tissue formation
- To provide antimicrobial activity against a broad spectrum of organisms (Correct answer)
- To autolytically debride necrotic tissue
- To reduce pain at the wound site
Correct answer: To provide antimicrobial activity against a broad spectrum of organisms
Silver ions released by these dressings exert broad-spectrum antimicrobial effects by disrupting bacterial cell membranes and interfering with metabolic enzymes.
Question 5: In wound care documentation, MASD stands for:
- Moisture-Associated Skin Damage (Correct answer)
- Medical Adhesive Skin Dermatitis
- Minimal Absorbency Standard Dressing
- Macerated And Slough Deterioration
Correct answer: Moisture-Associated Skin Damage
Moisture-Associated Skin Damage (MASD) is a category of skin damage caused by prolonged exposure to urine, feces, wound exudate, perspiration, or other moisture sources.
Question 6: When assessing wound exudate, which color is most associated with a possible Pseudomonas infection?
- Clear/straw-colored
- Yellow/tan
- Blue-green (Correct answer)
- Bloody/serosanguineous
Correct answer: Blue-green
Pseudomonas aeruginosa produces pyocyanin, a blue-green pigment, which gives wound exudate a characteristic blue-green or teal color.
Question 7: Which of the following is a key principle of 'moist wound healing'?
- Allowing wounds to dry out and form a scab promotes faster epithelialization
- Maintaining a moist wound environment accelerates cell migration and healing (Correct answer)
- Daily wound irrigation with hydrogen peroxide optimizes moisture balance
- Dry dressings should be used on all partial-thickness wounds
Correct answer: Maintaining a moist wound environment accelerates cell migration and healing
Research since Winter's 1962 study confirms that a moist wound environment accelerates epithelial cell migration, promotes autolytic debridement, and reduces pain compared to dry healing.
