Wound Care Certification (WCC) Exam — Questions and Answers
Question 1: Which of the following findings would correctly identify a pressure injury as Stage 3?
- Full-thickness skin loss with visible adipose (fat) tissue and granulation tissue. (Correct answer)
- Intact skin with non-blanchable erythema.
- Full-thickness skin and tissue loss with exposed muscle and bone.
- Partial-thickness skin loss with exposed dermis.
Correct answer: Full-thickness skin loss with visible adipose (fat) tissue and granulation tissue.
A Stage 3 pressure injury is characterized by full-thickness loss of skin, where adipose (fat) is visible in the ulcer. Granulation tissue and epibole (rolled wound edges) are often present. Muscle, tendon, or bone are not exposed in a Stage 3 injury.
Question 2: When managing a wound confirmed to be pyoderma gangrenosum that is in an active, inflammatory phase, which of the following interventions is generally contraindicated?
- Application of a non-adherent dressing
- Topical immunosuppressants
- Aggressive sharp debridement (Correct answer)
- Systemic corticosteroid therapy
Correct answer: Aggressive sharp debridement
Aggressive sharp or surgical debridement is contraindicated in active pyoderma gangrenosum due to the pathergy phenomenon. Pathergy is a condition where trauma to the skin, including debridement, can trigger a severe inflammatory response, causing the ulcer to rapidly worsen or new ulcers to form. Management focuses on potent anti-inflammatory and immunosuppressive therapy.
Question 3: Which mechanism explains why patients with chronic kidney disease (CKD) experience impaired wound healing?
- Decreased renin production reduces tissue perfusion
- Uremic toxins inhibit fibroblast proliferation and collagen synthesis (Correct answer)
- Hyperkalemia directly damages keratinocytes
- Elevated erythropoietin levels stimulate excess collagen
Correct answer: Uremic toxins inhibit fibroblast proliferation and collagen synthesis
Uremic toxins that accumulate in CKD inhibit fibroblast function and impair collagen synthesis, delaying wound repair.
Question 4: When taking steps to avoid friction that could lead to a pressure ulcer, which of the following should be avoided?
- Talcum powder (Correct answer)
- Skin sealants
- Alcohol-based skin barrier
- Cornstarch
Correct 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.
Question 5: Which nutritional deficiency most directly impairs hydroxylation of proline and lysine, weakening collagen cross-linking?
- Vitamin C deficiency (Correct answer)
- Zinc deficiency
- Iron deficiency
- Vitamin A deficiency
Correct answer: Vitamin C deficiency
Vitamin C (ascorbic acid) is a required cofactor for prolyl and lysyl hydroxylase enzymes that stabilize collagen's triple helix structure.
Question 6: What is osteomyelitis?
- Bone infection (Correct answer)
- A and B
- The presence of pathogenic organisms in the blood or tissue
- Infection of the intestine
Correct answer: Bone infection
Osteomyelitis is a medical term that specifically refers to an infection of the bone. This condition can be caused by bacteria, fungi, or other pathogens that reach the bone through the bloodstream, from nearby infected tissue, or directly through an open wound. It is a serious condition that often requires prolonged antibiotic treatment and sometimes surgical intervention.
Question 7: Do pressure ulcers typically develop over bony prominences and are caused by persistent pressure that damages the underlying tissue?
- FALSE
- TRUE (Correct answer)
Correct answer: TRUE
Pressure ulcers, also known as bedsores or decubitus ulcers, are typically caused by prolonged pressure on the skin and underlying tissue. This pressure usually occurs over bony prominences, restricting blood flow and leading to tissue damage and breakdown. Therefore, the statement accurately describes the common development and cause of pressure ulcers.
Question 8: If a lesion has been in the inflammatory phase of healing for 10 days without progressing and the surrounding skin has remained erythematous and edematous, which of the following should the healthcare provider initially suspect?
- Infection (Correct answer)
- Immunosuppression
- Secondary trauma
- Inadequate protein intake
Correct answer: Infection
If a wound remains in the inflammatory phase for an extended period (10 days without progression) and exhibits persistent signs like erythema (redness) and edema (swelling), infection should be the primary suspicion. Infection prolongs the inflammatory response, impairs the normal healing cascade, and can lead to further tissue damage and delayed wound closure.
Question 9: Collagen and elastin are the proteins that compose the dermis. Both of these proteins are in charge of:
- bacteria
- Decompenstaed CHF, Peripheral arterial disease, ABI </ = 0.5
- Secondary
- Giving skin tensile strength and providing the skin with elastic recoll (Correct answer)
Correct answer: Giving skin tensile strength and providing the skin with elastic recoll
Collagen and elastin are crucial proteins found in the dermis layer of the skin. Collagen provides the skin with its tensile strength and structural integrity, preventing tearing. Elastin, on the other hand, gives the skin its elasticity, allowing it to stretch and recoil back to its original shape. Together, these proteins ensure the skin's durability and flexibility.
Question 10: Which of the following is the primary mechanism by which smoking systemically impairs wound healing?
- Inducing a chronic anti-inflammatory state
- Reducing oxygen-carrying capacity and causing vasoconstriction (Correct answer)
- Increasing the patient's basal metabolic rate
- Causing peripheral vasodilation and increased bleeding
Correct answer: Reducing oxygen-carrying capacity and causing vasoconstriction
Nicotine is a potent vasoconstrictor, which reduces blood flow and perfusion to the wound. Additionally, carbon monoxide from smoke binds to hemoglobin with a much higher affinity than oxygen, reducing the blood's oxygen-carrying capacity and leading to tissue hypoxia, which is detrimental to all phases of healing.
Question 11: If a pressure ulcer is diagnosed as superficial and looks like a blister with epidermal and dermis loss, the ulcer is classified as a _____.
- stage III
- stage IV
- stage I
- stage II (Correct answer)
Correct answer: stage II
A Stage II pressure ulcer is defined by partial-thickness skin loss involving the epidermis and/or dermis. It often presents as a shallow open ulcer with a red-pink wound bed, or as an intact or ruptured serum-filled blister, which aligns with the description of a superficial blister with epidermal and dermis loss.
Question 12: When it is appropriate for the resident's condition and consistent with the resident's goals, the removal of devitalized tissue in pressure ulcers is _____.
- irrigation
- debridement (Correct answer)
- sterile technique
- exudates
Correct answer: debridement
Debridement is the medical procedure involving the removal of devitalized (dead or necrotic) tissue from a wound. This process is crucial for wound healing as it eliminates tissue that can harbor bacteria and impede the growth of healthy granulation tissue, making it appropriate for pressure ulcers when consistent with the resident's condition and goals.
Question 13: When a chemotherapeutic agent is given to a patient, and they get a tissue reaction in an area that has already been irradiated.
- Radiation recall (Correct answer)
- B & C
- Primary, secondary, tertiary
- 14-18 gm/dl
Correct answer: Radiation recall
Radiation recall is an inflammatory skin reaction that occurs in a previously irradiated area when certain chemotherapy drugs are administered, even months or years after radiation therapy. The chemotherapy effectively 'recalls' the prior radiation damage, causing symptoms like redness, swelling, and blistering within the treated field.
Question 14: When repositioning a patient to prevent pressure injuries on the sacrum, what is the recommended side-lying position?
- A 30-degree lateral inclined position. (Correct answer)
- The prone position.
- A 90-degree lateral position.
- A high-Fowler's position.
Correct answer: A 30-degree lateral inclined position.
The 30-degree lateral inclined position is recommended to relieve pressure from the sacrum and coccyx without placing the full weight on the trochanter, which can happen in a 90-degree position. This position effectively offloads common pressure points.
Question 15: An 82-year-old resident of a long-term care facility has a non-healing pressure injury. A nutritional assessment reveals a low pre-albumin level and inadequate protein consumption. A deficiency in protein will primarily disrupt which aspect of wound healing?
- Controlling bacterial bioburden
- Angiogenesis and collagen synthesis (Correct answer)
- Platelet aggregation during hemostasis
- Initial vasoconstriction of blood vessels
Correct answer: Angiogenesis and collagen synthesis
Protein and its constituent amino acids are the fundamental building blocks for new tissue. They are essential for fibroblast proliferation, the synthesis of collagen (the primary structural protein in the wound matrix), and angiogenesis (the formation of new blood vessels).
Question 16: Which diagnostic test is best recommended for a patient who follows a strict vegan diet and doesn't eat any foods containing gluten or legumes?
- Vitamin D level
- Zinc level (Correct answer)
- BUN
- Prealbumin
Correct answer: Zinc level
Zinc is an essential trace element vital for numerous physiological processes, including wound healing, immune function, and protein synthesis. A strict vegan diet that also excludes gluten and legumes (common dietary sources of zinc) significantly increases the risk of zinc deficiency. Therefore, a zinc level test is the most appropriate diagnostic to assess nutritional status related to wound healing in this patient.
Question 17: Which laboratory value is the BEST indicator of a patient's long-term nutritional status and protein availability for wound healing?
- Prealbumin (transthyretin) (Correct answer)
- Serum albumin
- C-reactive protein
- Hemoglobin A1c
Correct answer: Prealbumin (transthyretin)
Prealbumin has a half-life of 2–3 days, making it the most sensitive short-to-medium-term marker of current protein status and nutritional change.
Question 18: A comprehensive wound assessment should include multiple components to guide the plan of care. Which of the following is the MOST complete list of essential assessment components?
- Anatomical location, dimensions (length, width, depth), wound bed tissue types, drainage characteristics, and condition of the periwound skin. (Correct answer)
- Location, size, drainage amount, and pain level.
- Presence of odor and the patient's nutritional status.
- Wound size and color only.
Correct answer: Anatomical location, dimensions (length, width, depth), wound bed tissue types, drainage characteristics, and condition of the periwound skin.
A thorough wound assessment must be comprehensive to be effective. This includes precise anatomical location, measurements (length, width, depth, and any undermining or tunneling), assessment of the tissue types in the wound bed (e.g., granulation, slough, eschar), characteristics of any exudate (amount, color, consistency), and the condition of the skin surrounding the wound (periwound).
Question 19: Obesity impairs wound healing through which DIRECT mechanism?
- High BMI triggers autoimmune destruction of fibroblasts
- Adipose tissue is poorly vascularized, reducing oxygen tension at wound edges (Correct answer)
- Increased serum lipids coat collagen fibers, preventing cross-linking
- Obesity elevates platelet count, causing excessive clot formation
Correct answer: Adipose tissue is poorly vascularized, reducing oxygen tension at wound edges
Adipose tissue has relatively poor blood supply, resulting in lower oxygen tension in subcutaneous layers and impairing the oxygen-dependent steps of wound healing.
Question 20: An illustration of a wound that most likely may see secondary healing is
- an extensive contaminated dog bite wound
- a split-thickness graft
- an infected wound (Correct answer)
- a clean laceration
Correct answer: an infected wound
Secondary intention healing occurs when a wound is left open to heal by granulation, contraction, and epithelialization, rather than being surgically closed. This method is preferred for wounds with significant tissue loss, heavy contamination, or infection, as it allows for drainage and reduces the risk of abscess formation. An infected wound is a prime example where primary closure would trap bacteria and worsen the infection, making secondary healing the safer choice.
Question 21: Silver-containing dressings are MOST indicated for which wound condition?
- Critically colonized or locally infected wound (Correct answer)
- Wound with heavy fibrinous slough only
- Clean surgical wound closed by primary intention
- Wound in the remodeling phase
Correct answer: Critically colonized or locally infected wound
Silver-containing dressings release silver ions that provide broad-spectrum antimicrobial activity, making them appropriate for critically colonized or locally infected wounds.
Question 22: Which physical finding is most consistent with chronic venous insufficiency of the lower extremity?
- Lipodermatosclerosis and hemosiderin staining (Correct answer)
- Pallor on elevation and rubor on dependency
- Dry, shiny, hairless skin with nail changes
- Absent pedal pulses and dependent rubor
Correct answer: Lipodermatosclerosis and hemosiderin staining
Lipodermatosclerosis (subcutaneous fibrosis) and hemosiderin staining (brown discoloration) are hallmarks of chronic venous insufficiency from red blood cell extravasation.
Question 23: Honey-based wound dressings exert antimicrobial effects primarily through which mechanism?
- High osmotic pressure and hydrogen peroxide production (Correct answer)
- High pH environment
- Enzymatic debridement
- Moisture vapor transmission
Correct answer: High osmotic pressure and hydrogen peroxide production
Medical-grade honey creates high osmotic pressure and generates hydrogen peroxide through glucose oxidase activity, providing antimicrobial effects.
Question 24: Which statement about MRSA wound infections is correct?
- MRSA is sensitive to standard penicillin antibiotics
- MRSA only causes superficial skin infections
- MRSA cannot form biofilm
- MRSA requires vancomycin or alternative antibiotics for systemic treatment (Correct answer)
Correct answer: MRSA requires vancomycin or alternative antibiotics for systemic treatment
MRSA is resistant to beta-lactam antibiotics and typically requires vancomycin, daptomycin, or linezolid for systemic treatment.
Question 25: Which clinical sign is MOST suggestive of biofilm presence in a chronic wound?
- Increased wound depth
- High volume of sanguineous drainage
- Bright red granulation tissue
- Wound that fails to progress despite appropriate care (Correct answer)
Correct answer: Wound that fails to progress despite appropriate care
Failure to progress (wound stagnation) despite appropriate care is the most common clinical indicator of biofilm presence in chronic wounds.
Question 26: An ankle-brachial index (ABI) of 0.55 in a patient with a lower extremity wound most accurately indicates:
- Venous insufficiency with secondary arterial involvement
- Normal arterial perfusion adequate for healing
- Moderate to severe peripheral arterial disease (Correct answer)
- Mild arterial disease requiring monitoring only
Correct answer: Moderate to severe peripheral arterial disease
An ABI of 0.4–0.6 indicates moderate to severe peripheral arterial disease; values below 0.5 suggest critical limb ischemia requiring urgent vascular evaluation.
Question 27: A 35-year-old chef comes to the emergency room with a whole fingertip. She says that her knife fell while she was cutting up vegetables. She brought the pulp that had been cut off in a plastic bag. On examination, the patient's distal volar tip of the second finger has a clean, 5-mm-wide slice of skin. There is a lot of bleeding that doesn't pulsate. There is no damage to the distal interphalangeal joint (DIP), the proximal interphalangeal joint (PIP), or the nail. Her last tetanus shot was about a year ago. Which is the best next step in management?
- Immediately place the amputated tip on ice to prevent cell death.
- Discharge the patient with a pressure dressing and splint after the wound is irrigated and the bleeding is controlled. (Correct answer)
- Consult hand surgery for replantation of the pulp in the operating room.
- Irrigate the hand and replant distal tip in the ED as soon as possible.
Correct answer: Discharge the patient with a pressure dressing and splint after the wound is irrigated and the bleeding is controlled.
For small fingertip amputations, especially those involving only the pulp without bone exposure or significant joint involvement, conservative management is often preferred. The fingertip has excellent regenerative capacity, and healing by secondary intention with a pressure dressing and splint can lead to good functional and cosmetic outcomes. Replantation is typically reserved for larger, more complex amputations.
Question 28: Which phase constricts blood vessels to allow blood clotting and dilates to promote capillary permeability, allowing plasma and blood components to leak into the damaged area?
- Inflammatory phase
- Hemostasis (Correct answer)
- A and B
- Proliferation phase
Correct answer: Hemostasis
Hemostasis is the initial phase of wound healing, occurring immediately after injury. During this phase, blood vessels constrict to limit blood loss, and platelets aggregate to form a clot. Subsequently, vessels dilate to increase capillary permeability, allowing plasma and blood components to leak into the damaged area, which initiates the inflammatory response.
Question 29: Most likely to require specialized surgical intervention are lacerations involving:
- The vermilion border
- Medial portion of eyelid margin (Correct answer)
- Large forehead flap
- Fingertip/nailbed with suspected phalangeal fracture
Correct answer: Medial portion of eyelid margin
Lacerations involving the medial portion of the eyelid margin are highly complex due to the presence of the delicate lacrimal drainage system (tear ducts). Damage to these structures can lead to chronic tearing (epiphora) and infection if not meticulously repaired. Such repairs often require specialized ophthalmic surgical techniques to ensure proper alignment and function of the tear ducts, making it a critical area for specialized intervention.
Question 30: A key component of wound bed preparation is the TIME framework. What does the 'M' in this acronym represent?
- Medication application
- Mechanical debridement
- Measurement of wound dimensions
- Moisture imbalance (Correct answer)
Correct answer: Moisture imbalance
The 'M' in the TIME framework stands for Moisture imbalance. The framework guides clinicians to assess and manage four key areas to promote healing: Tissue (non-viable or deficient), Infection/Inflammation, Moisture imbalance, and Edge of wound (non-advancing).
Question 31: A 35-year-old man walks into the emergency room with a hole in his left foot where he stepped on a rusty nail. His last tetanus shot was when he was a child, which caused a severe allergic reaction and a long stay in the hospital. Which of these statements is true about this patient's tetanus immunization?
- Give tetanus toxoid.
- Give tetanus immunoglobulin and toxoid.
- Give neither tetanus toxoid nor immunoglobulin because he has had an allergic reaction in the past.
- Give tetanus immunoglobulin. (Correct answer)
Correct answer: Give tetanus immunoglobulin.
For a patient with a tetanus-prone wound and a documented history of a severe allergic reaction to tetanus toxoid, active immunization with the toxoid is contraindicated. In such cases, passive immunity is provided by administering tetanus immunoglobulin (TIG). TIG provides immediate, short-term protection against tetanus toxin without triggering an allergic response to the toxoid itself.
Question 32: A patient on long-term systemic corticosteroids presents with a non-healing surgical wound. Which cellular process is most directly impaired by corticosteroids?
- Erythrocyte oxygen transport
- Neutrophil and macrophage inflammatory response (Correct answer)
- Platelet aggregation at the wound site
- Endothelial cell apoptosis
Correct answer: Neutrophil and macrophage inflammatory response
Corticosteroids suppress the inflammatory phase by inhibiting neutrophil and macrophage activity, which are essential for wound debridement and growth factor release.
Question 33: What is the primary purpose of performing periwound skin assessment during wound evaluation?
- To determine wound staging
- To select appropriate wound dressing
- To identify signs of wound edge complications and skin breakdown (Correct answer)
- To calculate total wound surface area
Correct answer: To identify signs of wound edge complications and skin breakdown
Periwound assessment identifies complications such as maceration, induration, erythema, or satellite lesions that affect treatment planning.
Question 34: A wound care nurse is assessing a shallow, open ulcer on a patient's ischium. The wound bed is pink and moist, with partial-thickness loss of the dermis. There is no slough, eschar, or granulation tissue visible. Adipose tissue is not exposed. How should this pressure injury be staged?
- Stage 2 (Correct answer)
- Unstageable
- Stage 3
- Stage 1
Correct answer: Stage 2
This wound should be staged as a Stage 2 pressure injury. A Stage 2 injury is defined as partial-thickness skin loss with an exposed dermis. The wound bed is viable, pink or red, moist, and may also present as a serum-filled blister. The absence of slough, eschar, granulation tissue, and exposed adipose tissue are key characteristics of a Stage 2 injury.
Question 35: Which instruments are most commonly used for bedside conservative sharp debridement?
- Scalpel and curette (Correct answer)
- Electrocautery unit
- Ultrasound device
- Dermatome
Correct answer: Scalpel and curette
Scalpel and curette are the primary instruments for bedside conservative sharp debridement, allowing precise removal of necrotic tissue.
Question 36: What should be considered when assessing a patient's nutritional status is the typical daily caloric requirement for effective wound healing?
- 2000 to 3000 cal/day
- 1500 to 3500 cal/day (Correct answer)
- 3000 to 4000 cal/day
- 1000 to 1400 cal/day
Correct answer: 1500 to 3500 cal/day
Effective wound healing is an energy-intensive process that significantly increases the body's metabolic demands. To support tissue repair, collagen synthesis, and immune function, patients require an adequate caloric intake. A typical daily caloric requirement for optimal wound healing ranges from 1500 to 3500 calories, depending on the wound size, severity, and individual patient factors.
Question 37: What is full-thickness skin loss with subcutaneous tissue injury or necrosis?
- Stage II
- Stage I
- Stage III (Correct answer)
- Stage IV
Correct answer: Stage III
A Stage III pressure injury is characterized by full-thickness skin loss, meaning the damage extends through the epidermis and dermis. Subcutaneous fat may be visible, but bone, tendon, or muscle are not exposed. This stage often includes undermining and tunneling, indicating significant tissue destruction.
Question 38: All of the following are functions of a pressure-redistributing support surface EXCEPT:
- Reducing shear and friction forces.
- Eliminating the need for patient repositioning. (Correct answer)
- Immersing and enveloping the body to redistribute pressure.
- Controlling the microclimate of the skin.
Correct answer: Eliminating the need for patient repositioning.
While specialized support surfaces are a key component of pressure injury prevention, they do not eliminate the need for regular repositioning. Turning and repositioning remain a crucial intervention to alter the location, duration, and magnitude of pressure on vulnerable tissues, even when a therapeutic surface is in use.
Question 39: A patient has a pressure injury where the wound bed is not visible due to slough covering the entire base. How should this wound be staged?
- Stage 4
- Stage 3
- Deep Tissue Pressure Injury
- Unstageable (Correct answer)
Correct answer: Unstageable
When slough or eschar obscures the wound bed, the wound is classified as Unstageable because depth cannot be determined.
Question 40: Which of the following dressing categories is known for its ability to donate moisture to a dry wound bed, promoting autolytic debridement?
- Hydrocolloids
- Calcium alginates
- Amorphous hydrogels (Correct answer)
- Foam dressings
Correct answer: Amorphous hydrogels
Amorphous hydrogels are water- or glycerin-based products with a high moisture content (often over 90% water). They are specifically designed to donate moisture to dry or desiccated wound beds, which softens slough and eschar and facilitates autolytic debridement. Alginates and foams are absorptive, and hydrocolloids manage minimal to moderate exudate.
Question 41: A patient presents with a pressure injury over the coccyx. The assessment reveals full-thickness skin and tissue loss, with directly palpable fascia and muscle in the wound bed. Slough is present in 25% of the wound base, and undermining is noted from the 2 o'clock to 5 o'clock position. This wound would be classified as:
- Stage 2
- Stage 4 (Correct answer)
- Unstageable
- Stage 3
Correct answer: Stage 4
This wound is a Stage 4 pressure injury. The defining characteristic is full-thickness skin and tissue loss with exposed or directly palpable fascia, muscle, tendon, ligament, cartilage, or bone. While slough is present, it does not obscure the entire wound bed, allowing for determination of the wound's depth and the visualization of underlying structures, making it stageable.
Question 42: During a skin assessment, a nurse notes an area on the patient's heel that is intact, with a localized area of persistent, non-blanchable deep red discoloration. The patient reports pain in the area, which feels boggy upon palpation compared to the surrounding tissue. Which of the following is the most likely classification for this finding?
- Stage 1 Pressure Injury
- Stage 2 Pressure Injury
- Venous Stasis Ulcer
- Deep Tissue Pressure Injury (Correct answer)
Correct answer: Deep Tissue Pressure Injury
This presentation is characteristic of a Deep Tissue Pressure Injury (DTPI). A DTPI involves a localized area of persistent non-blanchable deep red, maroon, or purple discoloration of intact or non-intact skin. Pain and temperature changes often precede the skin color changes, and the tissue may feel boggy or firm.
Question 43: The kind of wound most likely to contract at the slowest rate is
- linear
- circular (Correct answer)
- square
- rectangular
Correct answer: circular
Circular wounds tend to contract at the slowest rate compared to other shapes like linear, rectangular, or square wounds. This is because the forces of contraction are distributed evenly around the circumference, making it less efficient in pulling the wound edges together. Linear wounds, for example, contract much faster along their length.
Question 44: Doctors remove wire sutures.
- TRUE (Correct answer)
- FALSE
Correct answer: TRUE
Wire sutures are a type of non-absorbable suture material used for strong, long-lasting wound closure. Since the body cannot naturally break down or absorb these materials, they must be manually removed by a healthcare professional once the wound has sufficiently healed. This prevents complications and ensures proper recovery.
Question 45: A patient with a Stage 3 pressure injury has a BMI of 16.2 and serum albumin of 2.1 g/dL. Which nutritional intervention is MOST appropriate to support wound healing?
- Initiate parenteral nutrition immediately regardless of GI function
- Supplement with vitamin C only and recheck albumin in 4 weeks
- Provide 1.25–1.5 g/kg/day protein with caloric supplementation (Correct answer)
- Restrict protein to 0.8 g/kg/day to prevent renal strain
Correct answer: Provide 1.25–1.5 g/kg/day protein with caloric supplementation
Malnourished patients with pressure injuries require 1.25–1.5 g/kg/day protein and adequate calories to support tissue repair.
Question 46: A 55-year-old man comes to the emergency room for stitches. A piece of glass cut his right calf when he was on vacation in Jamaica two days ago. The cut was 4 cm long. At that time, the cut was cleaned, an x-ray was taken to check for a foreign object, and it was fixed. At the moment, the edges of the wound are healing well and there is no redness or drainage from the wound. What is the best management step to take next?
- Remove the sutures then replace them to prevent infection.
- Have the patient return in 8 days for suture removal. (Correct answer)
- Have the patient return in 3 days for suture removal.
- Have the patient return in 14 days for suture removal.
Correct answer: Have the patient return in 8 days for suture removal.
The timing of suture removal depends on the wound location and the tension on the skin. For wounds on the extremities, such as the calf, sutures are typically left in place longer than on the face to allow for adequate tensile strength development and reduce the risk of dehiscence. An 8-day interval is an appropriate timeframe for suture removal on the calf, balancing healing with minimizing track marks.
Question 47: What is the gold standard for diagnosing wound infection?
- Elevated serum CRP
- Swab culture of wound surface
- Quantitative wound tissue biopsy culture (Correct answer)
- Visual inspection for purulence
Correct answer: Quantitative wound tissue biopsy culture
Quantitative tissue biopsy with ≥10^5 organisms per gram of tissue is the gold standard for diagnosing wound infection.
Question 48: Which term describes the progressive removal of necrotic tissue over multiple sessions using conservative sharp debridement?
- Surgical debridement
- Episodic debridement
- Serial debridement (Correct answer)
- Selective debridement
Correct answer: Serial debridement
Serial debridement refers to repeated conservative sharp debridement sessions performed incrementally to remove devitalized tissue over time.
Question 49: What form of drainage is Stewie Griffin experiencing from his wound, which appears clear and watery?
- Serous drainage (Correct answer)
- Serosanguineous drainage
- Purulent drainage
- Sanguineous drainage
Correct answer: Serous drainage
Serous drainage is a clear, watery fluid that is typically seen in healthy healing wounds. It consists of plasma and is a normal finding during the inflammatory phase of wound healing. This type of exudate indicates a healthy inflammatory response without signs of infection or significant bleeding.
Question 50: Which type of tissue should generally NOT be debrided in heel wounds?
- Slough
- Stable, dry, adherent eschar without signs of infection (Correct answer)
- Fibrinous exudate
- Soft, fluctuant eschar
Correct 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.
Question 51: Which characteristic distinguishes a Stage 3 pressure injury from a Stage 4 pressure injury?
- Depth extending through dermis
- Presence of slough in the wound bed
- Exposure of bone, tendon, or muscle (Correct answer)
- Presence of tunneling
Correct answer: Exposure of bone, tendon, or muscle
Stage 4 pressure injuries involve full-thickness tissue loss with exposed bone, tendon, or muscle, distinguishing them from Stage 3.
Question 52: Which intervention is MOST effective for disrupting wound biofilm?
- Increased dressing frequency alone
- Mechanical debridement combined with antimicrobial therapy (Correct answer)
- Topical antiseptics alone
- Systemic antibiotics alone
Correct answer: Mechanical debridement combined with antimicrobial therapy
Mechanical debridement physically disrupts the biofilm structure, and combined with antimicrobial therapy provides the most effective biofilm management.
Question 53: A wound care nurse selects a foam dressing for a moderate-exudate wound. What is the PRIMARY advantage of foam over gauze in this situation?
- Foam has inherent antimicrobial properties
- Foam eliminates the need for secondary dressings
- Foam provides a moist wound environment and thermal insulation (Correct answer)
- Foam is cheaper than gauze
Correct answer: Foam provides a moist wound environment and thermal insulation
Foam dressings maintain a moist healing environment and provide thermal insulation, which promotes wound healing compared to gauze.
Question 54: Which type of debridement is CONTRAINDICATED in a patient on warfarin therapy with a vascular wound?
- Enzymatic debridement
- Sharp/surgical debridement (Correct answer)
- Biological (maggot) debridement
- Autolytic debridement
Correct answer: Sharp/surgical debridement
Sharp debridement carries high bleeding risk in anticoagulated patients and is contraindicated unless in a controlled surgical setting.
Question 55: A nurse is completing a risk assessment for pressure injury using the Braden Scale on a new resident in a long-term care facility. The resident scores a 16. What is the appropriate interpretation of this score?
- The resident is at high risk.
- The resident is at mild risk. (Correct answer)
- The resident is at moderate risk.
- The resident has no risk.
Correct answer: The resident is at mild risk.
According to the Braden Scale for Predicting Pressure Sore Risk, a total score of 15-18 is categorized as mild risk. A score of 13-14 is moderate risk, 10-12 is high risk, and 9 or less is severe risk.
Question 56: Which dressing should be AVOIDED on a dry, necrotic eschar when autolytic debridement is the goal?
- Transparent film
- Dry gauze (Correct answer)
- Hydrogel sheet
- Hydrocolloid
Correct answer: Dry gauze
Dry gauze desiccates tissue and impedes autolytic debridement, making it counterproductive for softening dry eschar.
Question 57: Which product offers the best and longest skin protection against incontinence?
- Lotions
- Powders
- Moisturizers
- Moisture Barriers (Correct answer)
Correct answer: Moisture Barriers
Moisture barriers, typically in cream or paste form, create a protective layer on the skin that repels urine and feces, preventing direct contact with irritants. This physical barrier is crucial for shielding the skin from breakdown and irritation caused by prolonged exposure to moisture and enzymes in incontinent individuals. Unlike lotions or moisturizers, their primary function is to provide long-lasting protection against external moisture and irritants.
Question 58: What do you call a strip or roll of cloth or other material that can be wrapped around a body part in different ways for different purposes?
- Scarf
- Bandage (Correct answer)
- Bandana
- Gauze
Correct answer: Bandage
A bandage is a strip or roll of cloth or other material that can be wrapped around a body part for various purposes. Its main functions include covering and protecting a wound, securing a dressing, providing support to an injured limb, or applying compression to control swelling or bleeding.
Question 59: What kind of preparation is required for a patient who will be receiving chemical debridement with collagenase and who has a persistent leg ulcer covered in black eschar?
- Applying topical antibiotic
- Scrubbing the wound with hexachlorophene
- Thoroughly drying the eschar and surrounding skin
- Cross-hatching the upper layers of the eschar (Correct answer)
Correct answer: Cross-hatching the upper layers of the eschar
Black eschar is a hard, impenetrable layer of necrotic tissue. Cross-hatching creates small channels or cuts in the eschar, allowing the collagenase enzyme to penetrate deeper into the necrotic tissue. This increased penetration ensures the chemical debridement agent can effectively reach and break down the collagen, facilitating the removal of the eschar and promoting wound healing.
Question 60: Which component of the TIME framework specifically addresses the moisture balance in the wound environment?
- M – Moisture balance (Correct answer)
- E – Edge of wound
- T – Tissue management
- I – Infection/inflammation control
Correct answer: M – Moisture balance
The 'M' in TIME stands for Moisture balance, targeting excess exudate or desiccation that impairs healing.
Question 61: Blood stops bleeding during hemostasis. A cut made by a sharp instrument during surgery that gives access to an organ or space in the body.
- Stoma
- Puncture
- Abrasion
- Incision (Correct answer)
Correct answer: Incision
An incision is a precise, clean cut made into tissue or an organ using a sharp instrument, typically a scalpel, during a surgical procedure. Its purpose is to create an opening to access underlying structures or remove tissue, distinguishing it from other types of wounds like punctures (stab wounds) or abrasions (scrapes).
Question 62: When applying a hydrocolloid dressing, the clinician should ensure the dressing extends at least how far beyond the wound edge?
- 1–2 cm (Correct answer)
- 3–4 cm
- 5 cm
- 0.5 cm
Correct answer: 1–2 cm
Hydrocolloid dressings should overlap the intact periwound skin by 1–2 cm to ensure an adequate seal and prevent leakage.
Question 63: What is the main function of wet-to-dry dressings?
- To mechanically debride a wound (Correct answer)
- To provide an aesthetic appearance to wound dressing
- To perform aseptic cleansing
- To protect the wound from further injury
Correct answer: To mechanically debride a wound
Wet-to-dry dressings are primarily used for mechanical debridement of wounds. A moist dressing is applied to the wound bed and allowed to dry, adhering to necrotic tissue and debris. When the dried dressing is removed, it physically pulls away the dead tissue, helping to clean the wound and promote healing.
Question 64: 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?
- Primary
- Hemoglobin (Correct answer)
- iron deficiency
- B12 injection
Correct 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.
Question 65: Which organism is most commonly associated with wound biofilm formation?
- Streptococcus pyogenes
- Escherichia coli
- Staphylococcus aureus (Correct answer)
- Pseudomonas aeruginosa
Correct answer: Staphylococcus aureus
Staphylococcus aureus is the most common organism associated with wound biofilm formation and chronic wound infection.
Question 66: A 19-year-old girl comes to the ED with a cut on her lip. He got the cut when he got into an argument. On close inspection, he has a 2-cm horizontal cut in the middle of his lower right lip. The lower lip has gotten a lot bigger. The attending asks you, the intern, to do a mental block for anesthesia. Which of the following is a true statement about mental blocks?
- A mental block anesthetizes the mental nerve, which innervates the lower lip. (Correct answer)
- A mental block is not appropriate in this patient because it will lead to worsened swelling of the lower lip swelling.
- The patient requires a right-sided mental block.
- A mental block is performed by injecting lidocaine into the mental nerve foramen.
Correct answer: A mental block anesthetizes the mental nerve, which innervates the lower lip.
A mental block specifically targets the mental nerve, which is a branch of the inferior alveolar nerve. This nerve provides sensory innervation to the skin of the chin and the lower lip. Therefore, a mental block effectively anesthetizes the lower lip, making it an appropriate choice for repairing a laceration in that area.
Question 67: Which characteristic is most typical of an arterial (ischemic) ulcer of the lower extremity?
- Wet, macerated periwound skin with hemosiderin staining
- Pale, well-defined 'punched-out' margins with minimal exudate (Correct answer)
- Shallow, irregular borders located at the medial malleolus
- Irregular edges with ruddy granulation and heavy exudate
Correct answer: Pale, well-defined 'punched-out' margins with minimal exudate
Arterial ulcers have pale, well-defined 'punched-out' margins with minimal exudate because reduced blood flow limits tissue perfusion and wound moisture.
Question 68: Which diagnostic study is considered the gold standard for evaluating peripheral arterial disease anatomy prior to intervention?
- Toe-brachial index measurement
- Ankle-brachial index measurement
- Duplex ultrasonography of lower extremities
- Arteriography (catheter-based angiography) (Correct answer)
Correct answer: Arteriography (catheter-based angiography)
Catheter-based arteriography remains the gold standard for anatomical mapping of peripheral arterial disease due to its superior spatial resolution and simultaneous intervention capability.
Question 69: What is the PRIMARY goal of the Wound Hygiene protocol for biofilm management?
- Eliminating the need for systemic antibiotics
- Consistent cleanse, debride, dress, and reassess to suppress biofilm (Correct answer)
- Increasing moisture at the wound bed
- Reducing wound odor only
Correct answer: Consistent cleanse, debride, dress, and reassess to suppress biofilm
The Wound Hygiene protocol focuses on consistent cleansing, debriding, dressing, and reassessing to prevent biofilm maturation and maintain wound progress.
Question 70: What is the flow or escape of blood, serum, or lymph into the tissues?
- Extravasation (Correct answer)
- Adhesion
- Hematoma
- Evisceration
Correct answer: Extravasation
Extravasation refers to the leakage or escape of fluid, such as blood, serum, or lymph, from its normal vessel into the surrounding tissues. This can occur due to vessel damage, increased vascular permeability, or improper administration of intravenous fluids, leading to swelling, discoloration, and potential tissue damage.
Question 71: When measuring a wound, what is the correct anatomical orientation for wound length?
- Widest dimension regardless of direction
- Head to toe (superior to inferior) (Correct answer)
- Diagonal from corner to corner
- Side to side (medial to lateral)
Correct answer: Head to toe (superior to inferior)
Wound length is measured head to toe (superior to inferior) using the clock face analogy with 12 o'clock toward the head.
Question 72: Collagenase (Santyl) should NOT be used concurrently with:
- Transparent film dressings
- Hydrogel dressings
- Saline irrigation
- Silver-containing dressings or povidone-iodine (Correct answer)
Correct answer: Silver-containing dressings or povidone-iodine
Heavy metals such as silver and antiseptics like povidone-iodine inactivate collagenase, reducing its enzymatic effectiveness.
Question 73: Creating new blood vessels is formally called:
- Angina
- Coagulation
- Biogenesis
- Angiogenesis (Correct answer)
Correct answer: Angiogenesis
Angiogenesis is the physiological process of forming new blood vessels from pre-existing ones. In the context of wound healing, angiogenesis is a critical component of the proliferative phase, ensuring that the newly forming granulation tissue receives an adequate blood supply for oxygen, nutrients, and waste removal, which are essential for tissue repair.
Question 74: What happens to the skin (epidermis) as it ages?
- becomes thicker and dryer
- does not change
- None of the above
- becomes thinner and dryer (Correct answer)
Correct answer: becomes thinner and dryer
As skin ages, the epidermis (outermost layer) thins due to decreased cell turnover and flattening of the dermal-epidermal junction. Additionally, there's a reduction in natural oils and hyaluronic acid, leading to decreased moisture retention and increased dryness. These changes make aged skin more fragile, less elastic, and more susceptible to injury.
Question 75: A clinician documents wound undermining at '9 to 12 o'clock, extends 2 cm.' Using the clock face method, where is this undermining located?
- On the patient's left lateral to superior border
- On the patient's right medial to inferior border
- On the patient's right lateral to superior border (Correct answer)
- On the patient's inferior to left lateral border
Correct answer: On the patient's right lateral to superior border
With 12 o'clock toward the head, 9 o'clock is the patient's right side and 12 o'clock is superior, so undermining spans right lateral to superior.
Question 76: A 65-year-old patient with uncontrolled type 2 diabetes mellitus (HbA1c of 10.5%) presents with a full-thickness wound on their lower leg. All of the following are mechanisms by which hyperglycemia directly impairs wound healing EXCEPT:
- Accumulation of advanced glycation end products (AGEs)
- Increased production of pro-inflammatory cytokines
- Impaired leukocyte function and chemotaxis
- Enhanced fibroblast proliferation (Correct answer)
Correct answer: Enhanced fibroblast proliferation
Hyperglycemia impairs, rather than enhances, fibroblast function. High glucose levels reduce fibroblast proliferation and their ability to synthesize collagen, leading to a weaker and poorly formed wound matrix. The other options are all known negative effects of hyperglycemia on healing.
Question 77: A patient's coccyx has developed a pressure ulcer; based on what you know about wound closure methods, how do you think this wound will heal?
- Activation and aggregation
- Category 1A
- Irregular wound margins, heavy exudate, hemosiderin staining, medial lower leg, ruddy granular
- secondary intention (Correct answer)
Correct answer: secondary intention
A pressure ulcer on the coccyx typically involves significant tissue loss and often has irregular edges, making it unsuitable for primary closure (suturing). Therefore, such a wound will heal by secondary intention, meaning it is left open to heal from the bottom up through processes like granulation, wound contraction, and epithelialization. This method is slower and often results in a more noticeable scar.
Question 78: A honey-impregnated dressing works through which PRIMARY mechanism?
- High pH that inhibits bacterial growth
- Osmotic action and hydrogen peroxide generation (Correct answer)
- Keratinocyte growth factor stimulation
- Systemic absorption of antibiotics
Correct answer: Osmotic action and hydrogen peroxide generation
Medical-grade honey exerts antimicrobial effects primarily through osmotic activity and low-level hydrogen peroxide production.
Question 79: Where do you tie the square knot when using a triangle-shaped blinder (Sling)?
- at the lateral area of neck on uninjured side (Correct answer)
- at the lateral area of neck on the affected side
- at the dorsal area of neck close to the occiput
- right where the elbow is
Correct answer: at the lateral area of neck on uninjured side
When applying a triangular sling, the square knot should be tied at the lateral aspect of the neck on the uninjured side. This placement ensures that the knot does not press against the cervical spine or the injured area, maximizing patient comfort and preventing further irritation or pressure on sensitive tissues.
Question 80: Which statement about contact layer dressings is CORRECT?
- They absorb exudate and do not require a secondary dressing
- They are used as the primary absorbent layer
- They are placed directly on the wound bed and allow exudate to pass through (Correct answer)
- They should be changed every 24 hours
Correct answer: They are placed directly on the wound bed and allow exudate to pass through
Contact layer dressings are low-adherent materials placed on the wound surface to allow exudate passage to a secondary absorbent dressing.
Question 81: Which anatomical location is most typical for venous stasis ulcers?
- Lateral malleolus and outer ankle
- Plantar surface of the foot at bony prominences
- Medial malleolus and gaiter area of the lower leg (Correct answer)
- Tips of the toes and dorsum of the foot
Correct answer: Medial malleolus and gaiter area of the lower leg
Venous ulcers most commonly occur in the gaiter area around the medial malleolus due to the highest concentration of venous hypertension in that region.
Question 82: A transparent film dressing is MOST appropriate for which wound type?
- Infected surgical wound
- Superficial abrasion with minimal exudate (Correct answer)
- Stage 3 pressure injury with heavy exudate
- Cavity wound requiring packing
Correct answer: Superficial abrasion with minimal exudate
Transparent film dressings are semi-permeable and best suited for superficial wounds with little to no exudate.
Question 83: Larval (maggot) therapy works primarily through which mechanism?
- Creation of a hyperosmotic wound environment
- Secretion of proteolytic enzymes that selectively digest necrotic tissue (Correct answer)
- Generation of heat to liquefy eschar
- Physical disruption of tissue by larval movement
Correct answer: Secretion of proteolytic enzymes that selectively digest necrotic tissue
Medicinal maggots (Lucilia sericata larvae) secrete proteolytic enzymes that selectively digest necrotic tissue while sparing viable tissue.
Question 84: A nurse notices a dark purple discoloration on an intact heel of a patient admitted 6 hours ago. The area is firm and painful. This finding is BEST classified as:
- Unstageable pressure injury
- Stage 2 pressure injury
- Deep tissue pressure injury (DTPI) (Correct answer)
- Stage 1 pressure injury
Correct answer: Deep tissue pressure injury (DTPI)
Deep tissue pressure injury presents as intact skin with non-blanchable dark purple or maroon discoloration indicating injury to underlying soft tissue.
Question 85: A patient with poorly controlled hypothyroidism has a wound that is healing slowly. What is the primary reason thyroid hormone deficiency impairs healing?
- Low T3 causes hyperglycemia, damaging capillaries
- Thyroid hormone directly cleaves fibrin clots
- Hypothyroidism raises cortisol, suppressing inflammation
- Reduced basal metabolic rate decreases cellular energy for repair (Correct answer)
Correct answer: Reduced basal metabolic rate decreases cellular energy for repair
Thyroid hormones regulate basal metabolic rate; deficiency reduces the energy available for cell proliferation, protein synthesis, and tissue remodeling.
Question 86: A clinician is assessing a pressure injury on a patient's sacrum. The wound bed is completely obscured by a thick, leathery, black eschar. What is the correct stage for this pressure injury according to the NPIAP guidelines?
- Stage 4
- Unstageable (Correct answer)
- Stage 3
- Deep Tissue Injury
Correct answer: Unstageable
The correct stage is Unstageable. When the base of a full-thickness wound is covered by slough or eschar to the extent that the true depth cannot be determined, it is classified as Unstageable. Once the slough or eschar is removed, the wound will be revealed as either a Stage 3 or Stage 4 pressure injury.
Question 87: Which dressing type BEST supports autolytic debridement?
- Hydrocolloid or hydrogel dressings (Correct answer)
- Dry gauze
- Foam dressing
- Calcium alginate
Correct answer: Hydrocolloid or hydrogel dressings
Hydrocolloid and hydrogel dressings maintain a moist environment that supports the body's own enzymes in liquefying and separating necrotic tissue.
Question 88: A 5-year-old boy's mother takes him to the emergency room for a forehead injury. On the icy sidewalk, he slid and banged his head, she said. No unconsciousness. The child is aware and active. He has a 3-cm hairline-crossing forehead laceration. What is the best way to close the wound on this patient?
- Close with Steri-Strips
- Close with staples
- Close with interrupted sutures (Correct answer)
- Shave the hair surrounding the laceration and close with interrupted sutures
Correct answer: Close with interrupted sutures
For a 3-cm laceration on a child's forehead, interrupted sutures are the best choice for closure. They allow for precise approximation of the wound edges, which is crucial for achieving a good cosmetic outcome on the face. Interrupted sutures also provide strong closure and allow for individual adjustment of tension, accommodating for potential swelling or movement.
Question 89: Surgical debridement in the operating room is MOST appropriate for wounds with:
- Stable dry eschar on heels
- Minor fibrinous exudate
- Deep infection, exposed structures, or large necrotic tissue burden (Correct answer)
- Small amounts of superficial slough
Correct answer: Deep infection, exposed structures, or large necrotic tissue burden
OR debridement is indicated for wounds with deep infection, osteomyelitis, exposed bone or tendon, or extensive necrosis requiring wider tissue excision.
Question 90: Before performing any debridement, the clinician must FIRST assess:
- The patient's insurance coverage
- Wound etiology, tissue perfusion, and patient goals (Correct answer)
- Periwound skin color only
- Wound surface temperature only
Correct answer: Wound etiology, tissue perfusion, and patient goals
Wound etiology, perfusion status, and patient goals/consent must be assessed before debridement to avoid harming poorly vascularized tissue.
Question 91: A critically ill patient in the ICU is placed on a vasopressor. How does this medication increase pressure injury risk?
- It raises core body temperature, accelerating skin breakdown
- It causes agitation, increasing friction and shear forces
- It increases urine output, causing moisture-related skin breakdown
- It causes peripheral vasoconstriction, reducing tissue perfusion to bony prominences (Correct answer)
Correct answer: It causes peripheral vasoconstriction, reducing tissue perfusion to bony prominences
Vasopressors cause peripheral vasoconstriction, which reduces blood flow to skin over bony prominences and increases ischemia risk.
Question 92: Which debridement method is most appropriate for a patient with a large necrotic wound requiring rapid tissue removal?
- Surgical/sharp debridement (Correct answer)
- Wet-to-dry gauze
- Enzymatic debridement
- Autolytic debridement
Correct answer: Surgical/sharp debridement
Surgical or sharp debridement is the fastest method and is appropriate when rapid removal of large amounts of necrotic tissue is required.
Question 93: The word "slough" is used to describe a wound and means:
- a soft viscous yellow layer of necrotic tissue that covers and adheres to the wound (Correct answer)
- softening and irritation caused by akin contact with liquid
- bright pink or red granular new tissue formed from capillary beds
- formation of healed tissue from epidermal cells over granulation
Correct 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.
Question 94: Which of the following therapies is recommended as a first line of treatment for weepy, red, itchy atopic dermatitis?
- Topical antibiotic
- Wet aluminum acetate compresses (Correct answer)
- Topical antihistamine
- Hypoallergenic creams
Correct answer: Wet aluminum acetate compresses
Wet aluminum acetate (Burow's solution) compresses are a recommended first-line treatment for acute, weeping, red, and itchy atopic dermatitis. The solution has astringent and antiseptic properties that help to dry out the oozing lesions, reduce inflammation, and provide a soothing effect. This helps to alleviate itching and redness, promoting comfort and healing in the affected skin.
Question 95: On wounds, silver nitrate chemical cauterization is used to
- decrease exudate
- treat hypergranulation (Correct answer)
- control bleeding
- debride ulcer
Correct answer: treat hypergranulation
Silver nitrate chemical cauterization is commonly used in wound care to treat hypergranulation tissue, also known as 'proud flesh.' This excess granulation tissue can impede epithelialization and wound closure. Silver nitrate helps to reduce the hypergranulation by chemically burning the superficial layers, allowing the wound to progress to healing.
Question 96: Which bacterial count per gram of tissue indicates critical colonization or infection?
- 10^7
- 10^2
- 10^5 (Correct answer)
- 10^3
Correct answer: 10^5
A bacterial load of ≥10^5 organisms per gram of tissue is considered the diagnostic threshold for wound infection.
Question 97: 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.
- Dehiscence (Correct answer)
- A and B
- Fistula
- Evisceration
Correct 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.
Question 98: A ____ is a collection of infected fluid that hasn't drained away.
- Evisceration
- Abscess (Correct answer)
- Fistula
- Dehiscence
Correct answer: Abscess
An abscess is a localized collection of pus, which is infected fluid, that has not drained away. It forms when the body's immune system attempts to wall off an infection, creating a pocket of pus surrounded by inflamed tissue. This collection of fluid requires drainage to resolve the infection.
Question 99: When a patient has steri-strips, what is the best way to clean their bodies?
- Instruct patient not to take a bath
- Instruct patient to soak in bath tub
- Instruct patient just to wash face for a while
- Instruct a patient to take a shower (Correct answer)
Correct answer: Instruct a patient to take a shower
When a patient has steri-strips, taking a shower is generally the best way to clean their body. A shower allows for gentle cleansing without prolonged soaking, which could loosen the adhesive and cause the strips to detach prematurely. Soaking in a bathtub should be avoided to preserve the integrity of the steri-strips.
Question 100: A synonym for coagulation is:
- Clotting (Correct answer)
- Scar
- Inflammation
- Remodeling
Correct answer: Clotting
Coagulation is the physiological process where blood transforms from a liquid to a gel, forming a clot. This essential mechanism helps to stop bleeding after an injury. Therefore, 'clotting' is a direct and accurate synonym for coagulation, describing the same vital bodily function.
Question 101: What Is a Keloid?
- Same as an eschar only with a lighter color.
- A painful disease involving tissue damage.
- Overgrowth of a collagenous scar tissue at the site of the wound. (Correct answer)
- This is another phase of wound healing.
Correct 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.
Question 102: How long should topical antimicrobial therapy typically continue before reassessing effectiveness?
- 1-2 days
- 2 weeks (Correct answer)
- 3 months
- 6 weeks
Correct answer: 2 weeks
Topical antimicrobial therapy should be reassessed after 2 weeks to determine if wound bioburden is improving and whether therapy should continue or change.
Question 103: A 45-year-old patient undergoing a stressful divorce has a surgical wound that is showing signs of delayed healing. The elevation of which hormone, associated with chronic psychological stress, is known to suppress the immune system and impair wound repair?
- Insulin
- Melatonin
- Cortisol (Correct answer)
- Testosterone
Correct answer: Cortisol
Chronic psychological stress leads to prolonged elevation of cortisol levels. Cortisol, a glucocorticoid, suppresses the inflammatory response, inhibits the function of immune cells, and impairs overall immune function, all of which are detrimental to efficient wound healing.
Question 104: A patient with a history of ulcerative colitis presents with a rapidly expanding, extremely painful ulcer on the lower leg. The wound has irregular, undermined, violaceous borders and a purulent base. A key feature noted in the patient's history is the rapid worsening of the ulcer following a minor debridement attempt last week. What is the most likely etiology?
- Calciphylaxis
- Pyoderma Gangrenosum (Correct answer)
- Venous Ulcer
- Arterial Ulcer
Correct answer: Pyoderma Gangrenosum
The classic presentation of a rapidly enlarging, painful ulcer with violaceous, undermined borders in a patient with inflammatory bowel disease (ulcerative colitis) is highly characteristic of pyoderma gangrenosum. The worsening of the wound after debridement is a key diagnostic clue, representing the phenomenon of pathergy, where trauma exacerbates the condition.
Question 105: When repositioning a patient to prevent pressure injury, which technique BEST reduces shear forces?
- Elevating the head of bed to 90 degrees before turning
- Using a draw sheet or friction-reducing slide sheet to move the patient (Correct answer)
- Rolling the patient directly across the mattress surface
- Asking the patient to push with their heels during repositioning
Correct answer: Using a draw sheet or friction-reducing slide sheet to move the patient
Friction-reducing slide sheets minimize the shear and friction forces applied to skin during repositioning.
Question 106: Collagen production, intracellular cement substance maintenance, and iron absorption are all helped by this vitamin.
- Vitamin A
- Thiamine
- Zinc
- Vitamin C (Correct answer)
Correct answer: Vitamin C
Vitamin C, also known as ascorbic acid, is essential for several critical bodily functions, including the synthesis of collagen, a vital protein for skin, blood vessels, and connective tissues. It also plays a role in maintaining intracellular cement substances and significantly enhances the absorption of non-heme iron, making it crucial for wound healing and overall health.
Question 107: A patient has a Stage 3 pressure injury on the sacrum with moderate serosanguinous drainage. The surrounding skin is erythematous and beginning to show signs of maceration. Which topical agent is most appropriate for application to the *periwound* skin?
- A zinc oxide-based moisture barrier (Correct answer)
- A silver-impregnated cream
- Amorphous hydrogel
- Collagenase ointment
Correct answer: A zinc oxide-based moisture barrier
The primary goal for the periwound skin in this scenario is to protect it from moisture-associated skin damage (MASD) or maceration caused by wound exudate. A zinc oxide-based moisture barrier cream or ointment creates a protective film on the skin, repelling moisture and preventing further breakdown. Hydrogel would add moisture, collagenase is a debrider for the wound bed, and an antimicrobial is not indicated for non-infected periwound skin.
Question 108: From day 3 or 4 to day 21, when the injury happens, this phase of healing gets longer. The area has more collagen. Capillaries run across the wound.
- Proliferative phase (Correct answer)
- Inflammatory phase
- None of these
- Maturation phase
Correct answer: Proliferative phase
The proliferative phase of wound healing typically occurs from day 3-4 to day 21 post-injury. During this phase, fibroblasts produce collagen, and new capillaries form (angiogenesis), leading to the development of granulation tissue that fills the wound bed. This stage is crucial for rebuilding tissue and closing the wound.
Question 109: Which of the following clinical findings is most suggestive of a malignant transformation within a chronic, non-healing wound, such as a Marjolin's ulcer?
- Hypergranulation with firm, everted (rolled) wound edges (Correct answer)
- Periwound hemosiderin staining
- Serosanguinous drainage
- Presence of yellow, stringy slough
Correct answer: Hypergranulation with firm, everted (rolled) wound edges
Malignant wounds, particularly Marjolin's ulcers (a squamous cell carcinoma arising in a chronic wound or scar), often present with specific signs of abnormal tissue growth. These include firm, raised, and everted (rolled) margins, and excessive or abnormal granulation tissue. The other options are common findings in various non-malignant chronic wounds.
Question 110: Peripheral arterial disease (PAD) impairs wound healing primarily by:
- Increasing venous hypertension and edema at the wound site
- Reducing oxygen and nutrient delivery due to arterial insufficiency (Correct answer)
- Causing lymphatic obstruction and protein accumulation
- Elevating inflammatory cytokines that degrade collagen
Correct answer: Reducing oxygen and nutrient delivery due to arterial insufficiency
PAD reduces arterial blood flow, limiting the oxygen and nutrients required for cellular proliferation and collagen synthesis.
Question 111: According to NPUAP/EPUAP guidelines, what is the MAXIMUM recommended head-of-bed elevation for patients at risk for pressure injuries, unless medically contraindicated?
- 15 degrees
- 30 degrees (Correct answer)
- 45 degrees
- 60 degrees
Correct answer: 30 degrees
The head of bed should be maintained at 30 degrees or less to minimize shear forces on the sacrum and coccyx.
Question 112: A wound exudes light pink and blood-tinged fluid on Peter Griffin. Which drainage is this?
- Purulent drainage
- Serous drainage
- Sanguineous drainage
- Serosanguineous drainage (Correct answer)
Correct answer: Serosanguineous drainage
Serosanguineous drainage is a type of wound exudate characterized by its light pink or blood-tinged appearance. It is a mixture of serous fluid (clear, watery plasma) and sanguineous fluid (red blood). This drainage indicates the presence of both plasma and a small amount of red blood cells, often seen in normal healing wounds.
Question 113: When a wound is first starting to heal, the first white blood cells to come are the ones whose job it is to ingest the bacteria and cell debris that have accumulated there.
- Leukocytes (Correct answer)
- A and B
- Macrophages
- Fibroblasts
Correct answer: Leukocytes
Leukocytes, specifically neutrophils, are the first white blood cells to arrive at a wound site during the inflammatory phase of healing. Their primary function is to phagocytose (ingest) bacteria, foreign debris, and dead cells. This crucial action cleans the wound bed, preparing it for subsequent stages of tissue repair and regeneration.
Question 114: A 78-year-old male is admitted to the hospital with pneumonia and is largely immobile. Which of the following is the MOST critical initial step in a pressure injury prevention plan?
- Ordering a specialized low-air-loss mattress.
- Conducting a comprehensive skin assessment and risk evaluation. (Correct answer)
- Requesting a dietary consult for high-protein supplements.
- Establishing a 2-hour turning and repositioning schedule.
Correct answer: Conducting a comprehensive skin assessment and risk evaluation.
The foundational step in any pressure injury prevention plan is to first assess the patient's individual risk and inspect their skin. This comprehensive assessment guides all subsequent interventions, such as selecting an appropriate support surface, determining repositioning frequency, and implementing nutritional support.
Question 115: How quickly can biofilm reform on a wound after debridement?
- 1 month
- 2 weeks
- 1 week
- 24-72 hours (Correct answer)
Correct answer: 24-72 hours
Biofilm can begin reforming within 24-72 hours after debridement, necessitating consistent wound maintenance and antimicrobial strategies.
Question 116: After a primary assessment has shown that a wound doesn't threaten life or limb, the first step in treating a wound that needs sutures is:
- Irrigation
- Radiographic evaluation
- Local anesthesia (Correct answer)
- Exploration
Correct answer: Local anesthesia
After ensuring a wound is not life or limb-threatening, the immediate priority for a wound requiring sutures is to manage pain and allow for thorough assessment and treatment. Administering local anesthesia first ensures patient comfort, facilitates a more complete exploration, irrigation, and debridement of the wound, and allows for precise suturing without causing further distress. Without adequate anesthesia, these crucial steps would be difficult or impossible to perform effectively.
Question 117: During a dressing, forgetting to count the packing pieces raises the chance of _______.
- Bleeding
- Pain
- A piece of material being left behind (Correct answer)
- Legislative action
Correct answer: A piece of material being left behind
Forgetting to count packing pieces during a dressing change significantly increases the risk of leaving material behind in the wound. Retained foreign bodies can lead to serious complications such as infection, abscess formation, delayed healing, and even necessitate further surgical intervention. Therefore, meticulous counting is a critical safety measure.
Question 118: Which fistula treatment strategy is likely to be the most effective in preventing wound contamination from drainage for a significant open abdominal lesion that has a fistula on the posterior aspect?
- Saddle bagging
- Simple pouching
- Troughing
- Bridging (Correct answer)
Correct answer: Bridging
For a fistula located on the posterior aspect of a significant open abdominal wound, 'bridging' is the most effective strategy to prevent wound contamination. This technique involves creating a pathway or 'bridge' over the wound to direct the fistula drainage away from the open wound bed, often into a collection system. Bridging protects the healing wound from corrosive effluent and infection, which is crucial for promoting wound healing and preventing complications.
Question 119: Which topical antimicrobial is most appropriate for MRSA-infected wounds?
- Neomycin
- Silver-containing dressings (Correct answer)
- Petroleum gauze
- Bacitracin
Correct answer: Silver-containing dressings
Silver-containing dressings have broad-spectrum antimicrobial activity effective against MRSA and are widely used for infected chronic wounds.
Question 120: Conservative sharp debridement is defined as removal of devitalized tissue:
- Only by licensed physicians
- Only in an operating room setting
- Under general anesthesia
- Without intentional cutting of viable tissue (Correct answer)
Correct answer: Without intentional cutting of viable tissue
Conservative sharp debridement removes only non-viable tissue without cutting into viable tissue, differentiating it from surgical debridement.
Question 121: Which support surface is ideal for a palliative care patient who is unable to assume a range of postures without feeling discomfort and putting pressure on two stage I and stage II ulcers?
- Alternating air mattress (Correct answer)
- High air loss (Air fluidized)
- Static flotation (water)
- Foam
Correct answer: Alternating air mattress
For a palliative patient with existing pressure ulcers and discomfort, an alternating air mattress is ideal. This type of mattress continuously inflates and deflates different air cells, constantly changing the pressure points on the body. This redistribution of pressure helps to prevent further skin breakdown, improve circulation, and significantly enhance patient comfort without requiring frequent, painful manual repositioning.
Question 122: A clinician is developing a plan of care for a non-healing wound on an elderly patient. Which age-related physiological change is a key systemic factor that contributes to delayed wound repair?
- A heightened and more rapid inflammatory response
- Increased epidermal thickness and skin turgor
- Enhanced angiogenesis and capillary growth
- Reduced collagen synthesis and fibroblast activity (Correct answer)
Correct answer: Reduced collagen synthesis and fibroblast activity
With advanced age, there is a natural decline in the number and activity of fibroblasts. This leads to decreased and disorganized collagen synthesis, resulting in a slower rate of healing and reduced tensile strength of the repaired tissue. The inflammatory response is often delayed and prolonged in older adults.
Question 123: A clinician is preparing a chronic wound for a skin graft. The wound bed has pale, friable granulation tissue that bleeds easily, and the epithelial edges are stalled and not advancing. These signs are most indicative of which underlying problem?
- Over-use of enzymatic debriding agents
- Excessive moisture in the wound bed
- Inadequate protein intake
- High bacterial bioburden or critical colonization (Correct answer)
Correct answer: High bacterial bioburden or critical colonization
Pale, friable granulation tissue and stalled epithelial edges are classic signs of critical colonization or a high bacterial bioburden (biofilm). These microorganisms disrupt the healing process, leading to unhealthy tissue formation and preventing wound closure. Addressing the bioburden is a critical step before a skin graft can be successful.
Question 124: Sharp debridement is contraindicated in wounds with:
- Heavy fibrinous exudate
- Moderate serous drainage
- Poor arterial blood supply and ischemia (Correct answer)
- Large amounts of slough
Correct answer: Poor arterial blood supply and ischemia
Sharp debridement is contraindicated in ischemic wounds due to the risk of creating non-healing wounds or worsening necrosis without adequate perfusion.
Question 125: Which of the following is the appropriate intervention when a wound has a damaged matrix and cell debris that prevents healing?
- Moisture-balancing dressings
- Antimicrobials
- Negative pressure wound therapy
- Debridement (Correct answer)
Correct answer: Debridement
Debridement is the essential intervention for wounds with damaged matrix and cell debris, as non-viable tissue and foreign material impede the healing process. Removing this necrotic tissue and debris promotes the formation of healthy granulation tissue, reduces the bacterial load, and allows the wound to progress through the normal stages of healing. Without debridement, chronic inflammation and infection can persist, preventing wound closure.
Question 126: If you've lost ___ of your weight in the last three months, that means your nutrition has gone down a lot.
- Calciphylaxis
- Medical Battery
- patient abandonment
- 10% (Correct answer)
Correct answer: 10%
Unintentional weight loss of 10% or more over a three-month period is a significant indicator of nutritional decline and is often used as a criterion for malnutrition risk. This level of weight loss suggests a severe catabolic state or inadequate caloric and nutrient intake, which can severely impair wound healing and overall health.
Question 127: Which topical agent should be AVOIDED in wounds with exposed cartilage or bone due to cytotoxicity?
- Cadexomer iodine
- Medical-grade honey
- Full-strength Dakin's solution (Correct answer)
- Silver sulfadiazine
Correct answer: Full-strength Dakin's solution
Full-strength Dakin's solution (0.5% sodium hypochlorite) is highly cytotoxic and should be avoided on viable tissue, exposed bone, or cartilage.
Question 128: A patient in palliative care suddenly got a dark, pear-shaped ulcer on the sacrum. It had uneven edges and grew quickly. This means that the pt:
- Predicting pressure ulcer development and determining risk level
- FALSE
- Primary, secondary, tertiary
- A Kennedy Terminal Ulcer (Correct answer)
Correct answer: A Kennedy Terminal Ulcer
A Kennedy Terminal Ulcer (KTU) is a specific type of pressure injury that often appears suddenly in individuals who are terminally ill. It is characterized by its rapid onset, dark discoloration (often purple, black, or red), pear or butterfly shape, and irregular borders, typically found on the sacrum. This ulcer is considered a sign of the body's systemic decline rather than solely localized pressure.
Question 129: Metronidazole gel applied topically to a fungating wound primarily serves to:
- Stimulate angiogenesis
- Promote granulation tissue formation
- Reduce malodor caused by anaerobic bacteria (Correct answer)
- Debride necrotic tissue
Correct answer: Reduce malodor caused by anaerobic bacteria
Topical metronidazole gel targets anaerobic bacteria that produce volatile fatty acids responsible for wound malodor in fungating wounds.
Question 130: After an accident, a 29-year-old man comes to the ED with the cut shown below. There are no broken teeth, and he has tetanus. After an accident, a 27-year-old man comes to the ED with the cut shown below. There are no broken teeth, and he is up to date on his tetanus shot. What are the best steps for management to take next? <br> <br> (Reproduced, with permission, from Knoop KJ, Stack LB, Storrow AB. Atlas of Emergency Medicine. New York, NY: McGraw-Hill, 2002: 162.)
- Infiltration of the lip with local anesthesia, closure of dermis and mucosal defects, and then approximation of the vermilion border
- Infiltration of local anesthesia into the lip and then approximation of the vermilion border
- Infraorbital nerve block and then approximation of the vermilion border (Correct answer)
- Infraorbital nerve block and closure of mucosal defects before the approximation of the vermilion border
Correct answer: Infraorbital nerve block and then approximation of the vermilion border
For lip lacerations, especially those involving the vermilion border, an infraorbital nerve block (for the upper lip) or a mental nerve block (for the lower lip) provides superior anesthesia compared to local infiltration. This approach avoids distorting the delicate lip anatomy with anesthetic fluid, which is crucial for precise alignment and approximation of the vermilion border, ensuring an optimal cosmetic outcome. Approximating the vermilion border accurately is the critical first step in closure.
Question 131: Which pressure ulcer is most severe?
- stage I
- stage II
- stage III
- stage IV (Correct answer)
Correct answer: stage IV
Pressure ulcers are staged from I to IV based on the depth of tissue damage, with Stage IV being the most severe classification. A Stage IV pressure ulcer involves full-thickness tissue loss with exposed bone, tendon, or muscle, indicating extensive damage to the underlying structures.
Question 132: A diabetic patient presents with a wound on the plantar surface of the foot over the first metatarsal head. What wound classification system is most appropriate?
- CEAP classification
- Bates-Jensen Wound Assessment Tool
- NPUAP pressure injury staging
- Wagner Ulcer Classification (Correct answer)
Correct answer: Wagner Ulcer Classification
The Wagner Ulcer Classification System is specifically designed for diabetic foot ulcers and grades severity from 0 to 5.
Question 133: Which clinical sign is MOST indicative of wound infection rather than normal inflammation?
- Serous exudate
- Increasing wound pain after initial improvement (Correct answer)
- Periwound erythema
- Wound warmth
Correct answer: Increasing wound pain after initial improvement
Increasing pain after initial improvement (secondary worsening) is a hallmark sign of wound infection rather than normal healing inflammation.
Question 134: Retention sutures: how long do they stay in place?
- Less than 14 days
- Between 10 and 14 days
- 14 days or more (Correct answer)
- Not more than 2 weeks
Correct answer: 14 days or more
Retention sutures are deep sutures used to provide additional strength and support to a wound closure, especially in areas of high tension or in patients with compromised healing. Due to their supportive role in the deeper layers, they are typically left in place for an extended period, often 14 days or more, to ensure adequate wound integrity during the critical healing phases.
Question 135: A clinician is assessing a new wound on a patient's upper arm. The wound has a sharply demarcated, linear and rectangular shape with clean edges, surrounded by healthy skin. The patient's explanation for the wound is vague and inconsistent with the observed pattern. What is the most probable underlying etiology?
- Pyoderma gangrenosum
- Vasculitic ulcer
- Atypical insect bite reaction
- Factitious wound (dermatitis artefacta) (Correct answer)
Correct answer: Factitious wound (dermatitis artefacta)
Factitious wounds, or dermatitis artefacta, are self-inflicted injuries. They are often characterized by bizarre, geometric, or linear shapes that are inconsistent with common wound etiologies. The location in an easily accessible area and a vague or incongruent patient history are also key indicators.
Question 136: A patient has a heavily exudating venous leg ulcer. Which dressing type is MOST appropriate to manage excess moisture?
- Transparent film
- Alginate (Correct answer)
- Hydrocolloid
- Petrolatum gauze
Correct answer: Alginate
Alginate dressings are highly absorbent and ideal for heavily exudating wounds such as venous leg ulcers.
Question 137: When using the moist wound healing principle, which dressing is MOST appropriate for a dry, necrotic wound to facilitate autolytic debridement?
- Antimicrobial gauze
- Hydrogel dressing (Correct answer)
- Foam dressing
- Alginate dressing
Correct answer: Hydrogel dressing
Hydrogel dressings donate moisture to dry necrotic tissue, promoting autolytic debridement.
Question 138: How would a wound that initially healed as expected but then showed signs of plateauing and stayed unaltered for the second and third weeks be classified?
- Acute wound
- Recalcitrant wound
- Stunned wound (Correct answer)
- Chronic wound
Correct answer: Stunned wound
A 'stunned wound' describes a wound that initially heals as expected but then plateaus or shows a significant slowdown in progress, remaining unaltered for several weeks. This term is used when the wound's healing trajectory has been interrupted or slowed, indicating a need to reassess the underlying factors affecting healing, without necessarily classifying it as a chronic wound yet.
Question 139: Which of the following complications could arise if a patient is positioned prone with their head tilted laterally to ease strain on their hips and spine?
- Decreased cerebral circulation and ocular damage (Correct answer)
- Injury to the peroneal nerve as well as dislocation of the hip and stress on the lower back and pelvis
- Diaphragm displaced anteriorly by abdominal viscera resulting in decreased functional residual capacity, especially in the elderly
- Increased intracranial pressure and increased intraocular pressure
Correct answer: Decreased cerebral circulation and ocular damage
When a patient is positioned prone with their head tilted laterally, there is a risk of compressing the carotid or vertebral arteries in the neck. This compression can lead to decreased cerebral circulation, potentially causing brain ischemia. Additionally, direct pressure on the eye or inadequate padding can result in ocular damage, such as corneal abrasions, retinal ischemia, or even vision loss.
Question 140: Which Braden Scale subscale directly measures the patient's ability to change and control body position?
- Moisture
- Mobility (Correct answer)
- Activity
- Friction and Shear
Correct answer: Mobility
The Mobility subscale assesses the patient's ability to change and control their body position independently.
Question 141: A wound clinician uses negative pressure wound therapy (NPWT) as part of wound bed preparation. What is the PRIMARY mechanism by which NPWT prepares the wound bed?
- It removes excess exudate and promotes granulation tissue formation (Correct answer)
- It replaces the need for debridement
- It delivers oxygen directly to the wound tissue
- It sterilizes the wound by creating anaerobic conditions
Correct answer: It removes excess exudate and promotes granulation tissue formation
NPWT removes excess exudate, reduces edema, and promotes granulation tissue formation, creating a favorable wound bed for healing or grafting.
Question 142: 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?
- 15 minutes
- 60 minutes (Correct answer)
- 10 minutes
- 35 minutes
Correct 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.
Question 143: How should the syringe be positioned when performing a wound irrigation?
- 1 inch above the wound (Correct answer)
- 1 mm above the wound
- 1 cm above the wound
- 1 finger-length above the wound
Correct answer: 1 inch above the wound
Positioning the syringe approximately 1 inch (or 2.5 cm) above the wound creates an optimal pressure for effective irrigation. This distance allows the stream of irrigant to generate sufficient force to dislodge debris and bacteria without causing additional tissue trauma or excessive splashing. Maintaining this distance ensures efficient wound cleansing while minimizing potential contamination of the surrounding area.
Question 144: Which wound exudate characteristic is most concerning and warrants immediate clinical evaluation?
- Serous exudate in a healing wound
- Increased drainage after compression therapy
- Serosanguineous drainage after debridement
- Purulent exudate with foul odor (Correct answer)
Correct answer: Purulent exudate with foul odor
Purulent exudate with foul odor indicates infection and requires immediate evaluation and intervention.
Question 145: What happens (mostly) in the first phase of wound healing?
- Inflammation
- Angiogenesis
- Granulation tissue formation
- Hemostasis (Correct answer)
Correct answer: Hemostasis
The first phase of wound healing, occurring immediately after injury, is hemostasis. This rapid process involves vasoconstriction to reduce blood flow, platelet aggregation to form a plug, and the activation of the coagulation cascade to form a stable fibrin clot. The primary goal is to stop bleeding and create a temporary seal.
Question 146: Wet-to-dry gauze debridement is classified as which type of debridement?
- Enzymatic debridement
- Biological debridement
- Selective debridement
- Non-selective mechanical debridement (Correct answer)
Correct answer: Non-selective mechanical debridement
Wet-to-dry dressings are non-selective mechanical debridement because they remove both necrotic and viable tissue as the dressing dries and adheres.
Question 147: What is the primary mechanism of action for autolytic debridement?
- The application of topical chemical enzymes to dissolve necrotic tissue.
- The use of the body's own enzymes and phagocytic cells to liquefy non-viable tissue. (Correct answer)
- The physical removal of dead tissue using irrigation or scrubbing.
- The surgical excision of devitalized tissue with a scalpel.
Correct answer: The use of the body's own enzymes and phagocytic cells to liquefy non-viable tissue.
Autolytic debridement harnesses the body's endogenous enzymes and phagocytic cells (like macrophages) to break down and digest necrotic tissue. This process is facilitated by creating a moist wound environment with moisture-retentive dressings, which allows these natural processes to occur effectively.
Question 148: When it comes to bandages and binders, a straight binder is utilized for ______.
- Chest and abdomen (Correct answer)
- Wrist, fingers, and trunk
- Head, fingers, and stump of an amputated limb
- Joints, such as the knee, elbow, ankle, and wrist
Correct answer: Chest and abdomen
A straight binder is a rectangular piece of fabric designed to provide support and compression to large, flat areas of the body. Its shape and size make it particularly suitable for wrapping around the chest or abdomen. It is commonly used to support surgical incisions, provide compression for rib fractures, or manage abdominal distention.
Question 149: Pressure ulcers can be caused by dehydration and malnutrition.
- TRUE (Correct answer)
- FALSE
Correct answer: TRUE
Dehydration and malnutrition are significant risk factors for the development of pressure ulcers. Inadequate fluid intake can lead to dry, less elastic skin, making it more vulnerable to breakdown, while insufficient protein and calorie intake impairs tissue repair and overall skin integrity, increasing susceptibility to pressure-related injuries.
Question 150: The most effective and least harmful way to lower the risk of wound infection is:
- Hydrogen peroxide skin preparation
- Cephalexin 50-75 mg/kg/d
- Normal saline irrigation 50-100 ml/cm of wound (Correct answer)
- Povidone-iodine scrub
Correct answer: Normal saline irrigation 50-100 ml/cm of wound
Thorough irrigation with normal saline is the most effective and least harmful method to reduce bacterial load and remove foreign debris from a wound. This mechanical cleansing action physically flushes out contaminants without damaging healthy tissue, unlike antiseptic solutions like povidone-iodine or hydrogen peroxide, which can be cytotoxic. A high volume of irrigation (50-100 ml/cm) ensures adequate cleansing to significantly lower the risk of infection.
Question 151: A clinician is selecting an enzymatic debriding agent for a wound with adherent necrotic tissue. Which of the following is the primary mechanism of action for collagenase Santyl?
- It kills bacteria through the release of silver ions, which then allows for natural debridement.
- It physically pulls away devitalized tissue when the dressing is removed.
- It uses the body's own enzymes and moisture to break down necrotic tissue.
- It selectively digests denatured collagen that anchors non-viable tissue to the wound bed. (Correct answer)
Correct answer: It selectively digests denatured collagen that anchors non-viable tissue to the wound bed.
Collagenase is an exogenous enzyme that selectively targets and digests the denatured collagen filaments that anchor necrotic tissue to the wound bed. This facilitates debridement without harming viable granulation tissue. Using the body's own enzymes is autolytic debridement, killing bacteria describes an antimicrobial, and physically pulling away tissue describes mechanical debridement.
