Chapter 12: Inflammation and Healing Harding: Lewis’s Medical-Surgical Nursing, 12th Edition

Test Bank For Lewis's Medical-Surgical Nursing, 12th Edition by Mariann M. Harding, Jeffrey Kwong, Debra Hagler Chapter 12: Inflammation and Healing Harding: Lewis’s Medical-Surgical Nursing, 12th Edition MULTIPLE CHOICE 1. The nurse assesses a patient‘s surgical wound on the first postoperative day and notes redness and warmth around the incision. Which action by the nurse is appropriate? A. Obtain wound cultures. B. Document the assessment. C. Notify the health care provider. D. Assess the wound every 2 hours. ANS: B The incisional redness and warmth are indicators of the normal initial (inflammatory) stage of wound healing by primary intention. The nurse would document the wound appearance and continue to monitor the wound. Notification of the health care provider, assessment every 2 hours, and obtaining wound cultures are not indicated because the healing is progressing normally. 2. A patient with an open leg lesion has a white blood cell (WBC) count of 13,500/L and a band neutrophil count of 11%. Which prescribed action would the nurse take first? A. Obtain cultures of the wound. B. Begin antibiotic administration. C. Continue to monitor the wound for drainage. D. Redressthe wound with wet-to-dry dressings. ANS: A The increase in WBC count with the increased band neutrophils (shift to the left) indicates that the patient probably has a bacterial infection, and the nurse would obtain wound cultures. Antibiotic therapy and/or dressing changes may be started, but cultures should be done first. The nurse will continue to monitor the wound, but additional actions are needed as well. 3. A patient with a systemic bacterial infection reports feeling cold and has a shaking chill. Which assessment finding will the nurse expect next? A. Skin flushing B. Muscle cramps C. Rising body temperature D. Decreasing blood pressure ANS: C The patient‘s report of feeling cold and shivering indicate that the hypothalamic set point for temperature has increased and the temperature will be increasing. Because associated peripheral vasoconstriction and sympathetic nervous system stimulation will occur, skin flushing and hypotension are not expected. Muscle cramps are not expected with chills and shivering or with a rising temperature. 4. A young adult patient receiving antibiotics for an infected leg wound has a temperature of 101.8F (38.7C). The patient denies any discomfort. Which action would the nurse take? A. Apply a cooling blanket. B. Notify the health care provider. C. Check the patient‘s temperature again in 4 hours. D. Give acetaminophen prescribed as-needed for pain. ANS: C Mild to moderate temperature elevations (less than 103F) do not harm young adult patients and may benefit host defense mechanisms. Continue to monitor the temperature. Antipyretics are not indicated unless the patient has fever-related symptoms, and the patient does not require analgesics if not reporting discomfort. There is no need to notify the patient‘s health care provider of a fever in a patient who is already being treated for the infection or to use a cooling blanket for a moderate temperature elevation. 5. A patient‘s 4  3-cm leg wound has a 0.4-cm black area in the center of the wound surrounded by yellow-green semiliquid material. Which dressing would the nurse apply to the wound? A. Dry gauze dressing B. Nonadherent dressing C. Hydrocolloid dressing D. Transparent film dressing ANS: C The wound requires debridement of the necrotic areas and absorption of the yellow-green slough. A hydrocolloid dressing would accomplish these goals. Transparent film dressings are used for clean wounds or approximated surgical incisions. Dry dressings will not debride the necrotic areas. Nonadherent dressings will not absorb wound drainage or debride the wound. 6. The nurse notes that a patient‘s open abdominal wound widens as it extends deeper into the abdomen. How would the nurse document this characteristic? A. Eschar B. Slough C. Maceration D. Undermining ANS: D Undermining or “tunneling” is evident when a cotton-tipped applicator is placed in the wound and there is a narrower “lip” around the wound, which widens as the wound deepens. Eschar is a crusted cover over a wound. Slough and maceration refer to loosening friable tissue. 7. A patient with rheumatoid arthritis has been taking oral corticosteroids for 2 years. Which nursing action is most likely to detect early signs of infection in this patient? A. Monitor white blood cell counts. B. Check the skin for areas of redness. C. Measure the temperature every 2 hours. D. Ask about feelings of fatigue or malaise. ANS: D The earliest manifestation of an infection may be “just not feeling well.” Common clinical manifestations of inflammation and infection are frequently not present when patients receive immunosuppressive medications. 8. For which type of wound would the nurse plan to use a wet-to-dry dressing? A. A pressure injury with pink granulation tissue B. A surgical incision with pink, approximated edges C. A full-thickness burn filled with dry black crusted material D. An open lesion with purulent drainage and dry brown areas ANS: D Wet-to-dry dressings are used when there is minimal eschar to be removed. A full-thickness wound filled with eschar will require interventions such as surgical debridement to remove the necrotic tissue. Wet-to-dry dressings are not needed on approximated surgical incisions. Wet-to-dry dressings are not used on uninfected granulating wounds because of the damage to the granulation tissue. 9. A patient from a long-term care facility is admitted to the hospital with a sacral pressure injury. The base of the wound involves subcutaneous tissue. How would the nurse classify this pressure injury? A. Stage 1 B. Stage 2 C. Stage 3 D. Stage 4 ANS: C A stage 3 pressure injury has full-thickness skin damage and extends into the subcutaneous tissue. A stage 1 pressure injury has intact skin with some observable damage such as redness or a boggy feel. Stage 2 pressure injuries have partial-thickness skin loss. Stage 4 pressure injuries have full-thickness damage with tissue necrosis, extensive damage, or damage to bone, muscle, or supporting tissues. 10. A young male patient with paraplegia who has a stage 2 sacral pressure injury is being cared for at home by his family. To prevent further tissue damage, which instructions are most important for the nurse to teach the patient and family? A. Change the patient‘s bedding frequently. B. Apply a hydrocolloid dressing over the injury. C. Change the patient‘s position every 1 to 2 hours. D. Record the size and appearance of the injury weekly. ANS: C The most important intervention is to avoid prolonged pressure on bony prominences by frequent repositioning. The other interventions may also be included in family teaching. 11. Which action would the nurse perform as part of a wet-to-dry dressing change on a patient‘s stage 3 sacral pressure injury? A. Pour sterile saline onto the new dry dressings after packing the wound. B. Administer a prescribed PRN oral analgesic 60 minutes before the change. C. Apply antimicrobial ointment before repacking the wound with moist dressings. D. Soak the old dressings with sterile saline 30 minutes before the dressing change. ANS: B Mechanical debridement with wet-to-dry dressings is painful, and patients should receive pain medications before the dressing change begins. The new dressings are moistened with saline before being applied to the wound but not soaked after packing. Soaking the old dressings before removing them will eliminate the wound debridement that is the purpose of this type of dressing. Application of antimicrobial ointments is not indicated for a wet-to-dry dressing. 12. A new nurse performs a dressing change on a patient‘s stage 2 left heel pressure injury. Which action by the new nurse indicates a need for further teaching about pressure injury care? A. Cleaning the injury with half-strength peroxide B. Applying a hydrocolloid dressing on the injury C. Irrigating the pressure injury with saline using a 30-mLsyringe D. Inserting a sterile cotton-tipped applicator into the pressure injury ANS: A Pressure injuries should not be cleaned with solutions that are cytotoxic, such as hydrogen peroxide. The other actions by the new nurse are appropriate. 13. A patient arrives in the emergency department with a swollen ankle after a soccer injury. Which action would the nurse take? A. Elevate the ankle above heart level. B. Apply a warm moist pack to the ankle. C. Ask the patient to try bearing weight on the ankle. D. Assess the ankle‘s passive range of motion (ROM). ANS: A Soft tissue injuries are treated with rest, ice, compression, and elevation (RICE). Elevation of the ankle will decrease tissue swelling. Moving the ankle through the ROM will increase swelling and risk further injury. Cold packs should be applied the first 24 hours to reduce swelling. The nurse should not ask the patient to move or bear weight on the swollen ankle because immobilization of the inflamed or injured area promotes healing by decreasing metabolic needs of the tissues. 14. When admitting a patient with stage 3 pressure injuries on both heels, which information obtained by the nurse will have the most impact on wound healing? A. The patient has had the injuries for 6 months. B. The patient takes oral hypoglycemic agents daily. C. The patient states that the injuries are very painful. D. The patient has several incisions that formed keloids. ANS: B The use of oral hypoglycemics indicates diabetes, which can interfere with wound healing. The persistence of the injuries over the past 6 months is a concern, but changes in care may be effective in promoting healing. Keloids are not disabling, although the cosmetic effects may be distressing for some patients. Actions to reduce the patient‘s pain will be implemented, but pain does not directly affect wound healing. 15. After receiving a change-of-shift report, which patient would the nurse assess first? A. The patient who has multiple leg wounds with eschar to be debrided B. The patient receiving chemotherapy who has a temperature of 102F C. The patient who requires analgesics before a scheduled dressing change D. The newly admitted patient with a stage 4 pressure injury on the coccyx ANS: B Chemotherapy is an immunosuppressant. Fever in the immunosuppressed patient should be treated immediately with antibiotic therapy because infections can rapidly progress to septicemia. The nurse would assess the other patients as soon as possible after assessing and implementing appropriate care for the immunosuppressed patient. 16. Which patient‘s care could the nurse delegate to a licensed practical/vocational nurse (LPN/VN)? A. The patient who was just admitted after suturing of a full-thickness arm wound B. The patient who just reported increased tenderness and swelling in a leg wound C. The patient who requires teaching about home care for an open draining abdominal wound D. The patient who needs a hydrocolloid dressing change for a stage 3 sacral pressure injury ANS: D LPN/VN education and scope of practice include sterile dressing changes for stable patients. Initial wound assessments, patient teaching, and evaluation for possible poor wound healing or infection would be done by the registered nurse (RN). 17. The nurse is caring for a patient with diabetes who had abdominal surgery 3 days ago. Which finding is most important for the nurse to report to the health care provider? A. Blood glucose of 136 mg/dL B. Separation of proximal wound edges C. Patient reports increased incisional pain D. Small amount of serous wound drainage ANS: B Wound separation 3 days postoperatively indicates possible wound dehiscence and would be immediately reported to the health care provider. The other findings will also be reported but do not require intervention by the HCP as rapidly. 18. A patient who has diabetes and acute abdominal pain is admitted for an exploratory laparotomy. Which postoperative intervention would be the nurse‘s highest priority to promote wound healing? A. Maintaining the patient‘s blood glucose within a normal range B. Ensuring that the patient has an adequate dietary protein intake C. Giving antipyretics to keep the temperature less than 102F (38.9C) D. Redressing the surgical incision with a dry, sterile dressing twice daily ANS: A Elevated blood glucose will impair wound healing in multiple ways. Ensuring adequate nutrition is important for the postoperative patient, but a higher priority is blood glucose control. A temperature of 102F will not impact wound healing. Application of a dry, sterile dressing dailymay be ordered, but frequent dressing changes for a wound healing by primary intention is not necessary to promote wound healing. 19. Which finding is most important for the nurse to communicate to the health care provider when caring for a patient who is receiving negative-pressure wound therapy? A. Low serum albumin level B. Serosanguineous drainage C. Deep red and moist wound bed D. Cobblestone wound appearance ANS: A Low albumin levels may indicate an inadequate supply of amino acids for tissue repair. The other findings are expected with wound healing. 20. After the home health nurse teaches a patient‘s familymember about how to care for a sacral pressure injury, which finding indicates that additional teaching is needed? A. The family member uses a lift sheet to reposition the patient. B. The family member uses clean tap water to clean the wound. C. The family member dries the wound using a hair dryer on a low setting. D. The family member places contaminated dressings in a plastic grocery bag. ANS: C Pressure injuries need to be moist to facilitate wound healing. The other actions indicate a good understanding of pressure ulcer care. The use of lift sheets prevents shearing forces. Clean tap water is acceptable for home use on chronic pressure wounds. Proper disposal of contaminated dressings prevents the spread of infection.
