NU 272: Tissue Integrity Questions With Complete Solutions
Following a serious thermal burn, which complication will the nurse take action to prevent first?
Tissue hypoxia
Infection
Renal failure
Hypovolemia -correct answer Hypovolemia
After a burn, fluid from the body moves toward the burned area, which leads to intravascular fluid
deficit. Steps must be taken to prevent irreversible hypovolemic shock in the initial stages of treatment.
The inflammatory processes that affect the tissues cause additional injury, which contributes to tissue
hypoxia. Myoglobin and hemoglobin that were destroyed during the burn can result in acute renal
failure. Destruction of the skin barrier results in colonization of bacteria and can lead to life-threatening
infection in days following the burn.
Which type of debridement involves the use of surgical scissors, scalpels, and forceps to separate and
remove the eschar?
Mechanical
Surgical
Natural
Chemical -correct answer Mechanical
Mechanical debridement involves the use of surgical scissors, scalpels, and forceps to separate and
remove the eschar. Topical enzymatic debridement agents are available to promote debridement of the
burn wounds. With natural debridement, the dead tissue separates from the underlying viable tissue
spontaneously. Surgical debridement is an operative procedure involving either primary excision
(surgical removal of tissue) of the full thickness of the skin down to the fascia (tangential excision) or
shaving of the burned skin layers gradually down to freely bleeding, viable tissue.
During the late stages of healing, which intervention helps a burn wound to heal with minimal scarring?
Removing eschar from the skin

Applying continuous-compression wraps Wearing clothing to protect the burn from the sun Maintaining wound care irrigation -correct answer Applying continuous-compression wraps Applying continuous-compression wraps helps skin healing and prevents hypertrophied tissue from forming. Removing eschar from the skin, wearing clothing to protect the burn from the sun, and maintaining wound care irrigation are appropriate for the client with a burn wound, but these interventions don't necessarily help minimize scarring. When assessing a client with partial-thickness burns over 60% of the body, which finding should the nurse report immediately? Complaints of intense thirst Moderate to severe pain Urine output of 70 ml the first hour Hoarseness of the voice -correct answer Hoarseness of the voice Hoarseness is indicative of injury to the respiratory system and could indicate the need for immediate intubation. Thirst following burns is expected because of the massive fluid shifts and resultant loss, leading to dehydration. Pain, either severe or moderate, is expected with a burn injury. The client's urine output is adequate. A client with a severe electrical burn injury is treated in the burn unit. Which laboratory result would cause the nurse the most concern? BUN: 28 mg/dL K+: 5.0 mEq/L Na+: 145 mEq/L Ca: 9 mg/dL -correct answer BUN: 28 mg/dL

Prevent negative nitrogen balance in order to maximize healing A nurse practitioner administers first aid to a patient with a deep partial-thickness burn on his left foot. The nurse describes the skin involvement as the: Epidermal layer only. Epidermis and a portion of deeper dermis. Entire dermis and subcutaneous tissue. Dermis and connective tissue. -correct answer Epidermis and a portion of deeper dermis. A deep partial-thickness burn includes the epidermis, upper dermis, and a portion of the deeper dermis. A burn limited to the epidermal layer is classified as a superficial partial-thickness burn. The last two choices refer to a full-thickness burn. A nurse knows to assess a patient with a burn injury for gastrointestinal complications. Which of the following is a sign that indicates the presence of a paralytic ileus? Hyperactive bowel sounds Decreased peristalsis Fecal occult blood Hematemesis -correct answer Decreased peristalsis Decreased peristalsis and hypoactive bowel sounds are manifestations of a paralytic ileus. The nurse recognize what as an early sign of sepsis in a client with a burn injury? Normal body temperature Decreased heart rate

Elevated serum glucose Widened pulse pressure -correct answer Elevated serum glucose In clients with burn injuries early sepsis can be hard to detect. Clients with burn injuries exhibit tachycardia, tacypnea, and elevated body temperature, all typical indications of sepsis. In the client with burn injury, indications of sepsis include elevated serum glucose values, increased heart rate, and narrowing mean arterial pressure. Both the typical elevated temperature and a temperature of less than 96.8 F (36 C) can indicate sepsi in a client with a burn injury. A nurse is assessing a client admitted with deep partial-thickness and full-thickness burns on the face, arms, and chest. Which finding indicates a potential problem? Partial pressure of arterial oxygen (PaO2) value of 80 mm Hg Urine output of 20 ml/hour White pulmonary secretions Rectal temperature of 100.6° F (38° C) -correct answer Urine output of 20 ml/hour A urine output of less than 30 ml/hour in a client with burns indicates a deficient fluid volume. This client's PaO2 value falls within the normal range (80 to 100 mm Hg). White pulmonary secretions are normal. The client's rectal temperature isn't significantly elevated, and the slight increase in temperature probably results from the deficient fluid volume. You were thinking about PaO2 which should be 95-100 mm Hg A child tips a pot of boiling water onto his bare legs. The mother should: Avoid touching the burned skin and take the child to the nearest emergency department. Cover the child's legs with ice cubes secured with a towel. Immerse the child's legs in cool water. Liberally apply butter or shortening to the burned areas. -correct answer Immerse the child's legs in cool water.

an alginate dressing transparent film a hydrogel dressing an antimicrobial dressing -correct answer an alginate dressing Alginate dressings contain alginic acid from brown seaweed. Covered in calcium-sodium salts, they absorb exudate, maintain a moist wound environment, and facilitate autolytic debridement. A secondary dressing is required to secure them. Transparent film allows frequent assessment of the site but provides a barrier. A hydrogel dressing comprises an 80%-99% water base and is used with partial- and full-thickness wounds. An antimicrobial dressing has an antibiotic that reduces bacterial growth. When caring for a client with a 3-cm stage I pressure ulcer on the coccyx, which action may the nurse institute independently? Using a povidone-iodine wash on the ulceration three times per day Using normal saline solution to clean the ulcer and applying a protective dressing as necessary Applying an antibiotic cream to the area three times per day Massaging the area with an astringent every 2 hours -correct answer Using normal saline solution to clean the ulcer and applying a protective dressing as necessary The nurse may wash the area with normal saline solution and apply a protective dressing. These interventions will protect the area and are within the nurse's scope of practice. A nurse must obtain a physician's order to use a povidone-iodine wash or an antibiotic cream. Massaging with an astringent can further damage the skin. A nurse is measuring the wound of a stab victim by moistening a sterile, flexible applicator with saline, then inserting it gently into the wound at a 90-degree angle. The nurse then marks the point where the applicator is even with the skin, removes the applicator and measures with a ruler. What wound measurement is determined by this method? Size

Depth Tunneling Direction -correct answer Depth When measuring the depth of a wound, the nurse moistens a sterile, flexible applicator with saline and inserts it gently into the wound at a 90-degree angle, with the tip down. The nurse then marks the point on the swab that is even with the surrounding skin surface, or grasps the applicator with the thumb and forefinger at the point corresponding to the wound's margin. Finally, the nurse removes the swab and measures the depth with a ruler. Size is measured with a ruler on the outside of the wound. Tunneling is measured by a finger probe or sterile probe instrument. Direction is a visual inspection. The nurse caring for a postoperative client documents that the surgical incision is healing by: Primary intention Secondary intention Tertiary intention Systemic intention -correct answer Primary intention Explanation: The nurse would document the surgical wound as healing by primary intention as there is no tissue loss. Wounds healing from secondary intention are larger and have a greater loss of tissue and contamination. Wounds do not heal by tertiary intention or systemic intention. The nurse is developing a plan of care for a client with a stage 3 heel ulcer. Which intervention should the nurse include? Apply a hydrocolloidal dressing. Place the extremity in a dependent position. Cleanse the area with hydrogen peroxide, and wrap with clean gauze. Restrict protein intake, and encourage fluids. -correct answer Apply a hydrocolloidal dressing.

Wound bed When documenting an acute open wound, the nurse should consider the wound's size, the condition of the periwound skin (skin surrounding the wound), a description of the wound bed, and the wound edges and margins. The pattern of eruption relates to the patterns of lesions on a client's skin and does not apply to an acute open wound. The nurse is assessing a client for acute inflammation of a wound. For which symptom of infection does the nurse assess? Pallor Edema Hypothermia Tissue necrosis -correct answer Edema Cardinal signs of inflammation include rubor (redness), tumor (swelling or edema), calor (heat), dolor (pain) and functio laesa (loss of function). Tissue necrosis occurs with chronic inflammation. While examining a client's leg, a nurse notes an open ulceration with visible granulation tissue in the wound. Until a wound specialist can be contacted, which type of dressing should the nurse apply? Dry sterile dressing Sterile petroleum gauze Moist sterile saline gauze Povidone-iodine-soaked gauze -correct answer Moist sterile saline gauze Moist sterile saline dressings support wound healing and are cost-effective. Dry sterile dressings adhere to the wound and debride the tissue when removed. Petroleum supports healing but is expensive. Povidone-iodine is used as an antiseptic cleaning agent but because it can irritate epithelial cells, it shouldn't be left on an open wound.

A nurse is assessing a pressure injury on a client's coccyx area. The wound size is 2 cm × 5 cm. Approximately 30% of the wound bed is covered in yellow slough. There is an area of undermining to the right side of the wound, 2 cm deep. Subcutaneous fat is visible. Which stage should the nurse assign to this client's wound? stage I stage II stage III stage IV -correct answer stage III Stage III wounds have full-thickness tissue loss. Subcutaneous tissue may be visible, but no bone, tendon, or muscle should be seen. Stage I involves intact skin with nonblanchable redness. Stage II involves a partial tissue loss, such as a blister. Stage IV involves full-thickness tissue loss with exposed bone, tendon, or muscle. On postoperative day 2, a client requires care for a surgical wound using second-intention healing. What type of dressing change should the nurse anticipate doing? Packing the wound bed with sterile saline-soaked dressing and covering it with a dry dressing Covering the well-approximated wound edges with a dry dressing Cleaning the wound with sterile saline and applying cyanoacrylate tissue adhesive Cleaning the wound with soap and water, then leaving it open to the air -correct answer Packing the wound bed with sterile saline-soaked dressing and covering it with a dry dressing Postoperative surgical wounds that are allowed to heal using second-intention healing are usually packed with a sterile saline-soaked dressing and covered with a dry dressing. The edges of a wound healing by second intention are not approximated. The wound may be cleaned using sterile saline, but the nurse would not apply a cyanoacrylate tissue adhesive. The wound should not be left open to the air, as it could expose the wound to microorganisms and dry out the wound bed, impairing healing.
