ATI Engage Fundamentals: Tissue Integrity- Posttest Questions and Answers | Latest Version | 2025/2026 | Correct & Verified What is the difference between a stage 1 and a stage 2 pressure ulcer? A stage 1 pressure ulcer involves intact skin with non-blanchable redness, while a stage 2 ulcer presents with partial-thickness loss of dermis, often appearing as a blister or shallow open ulcer. How can you assess for early signs of pressure ulcer development? Early signs include redness or discoloration that does not fade when pressure is applied, skin that feels warmer or cooler than surrounding areas, or discomfort/pain in a localized area. What is the role of the dermis in tissue integrity? The dermis provides structural support to the skin, containing blood vessels, nerves, and collagen that help maintain skin strength and elasticity. What is the significance of assessing for a patient's nutritional status in relation to tissue integrity? 2 Poor nutrition can delay wound healing and increase the risk of pressure ulcers, as adequate protein, vitamin C, and zinc are necessary for tissue repair. What does blanchable skin indicate during a skin assessment? Blanchable skin indicates that the blood flow is temporarily restricted but can return to normal once pressure is removed, suggesting no permanent damage to tissue. What factors increase the risk of pressure ulcers in a patient? Factors include immobility, incontinence, poor nutrition, age, chronic conditions like diabetes, and decreased sensory perception. How does moisture contribute to the development of pressure ulcers? Excess moisture from perspiration or incontinence can soften the skin, increasing the likelihood of friction and breakdown, which contributes to the development of pressure ulcers. What are the common sites for pressure ulcer formation? Common sites include bony prominences such as the heels, sacrum, elbows, and hips, where pressure is most concentrated. 3 What is the first step in preventing pressure ulcers in a patient at risk? The first step is to implement a routine for repositioning the patient at regular intervals to alleviate pressure from vulnerable areas. What is the significance of a black eschar in a wound assessment? A black eschar indicates necrotic tissue, which must be debrided before healing can occur. It is often seen in deeper stage wounds, especially stage 4 pressure ulcers. What is the best way to prevent friction-related skin injuries? Using moisture-wicking fabrics, applying protective barriers such as lotions or powders, and avoiding direct skin-to-skin contact can help reduce friction and prevent injury. What type of wound healing occurs in a clean surgical incision? Primary intention healing occurs in clean surgical wounds, where edges are approximated and healing happens with minimal scarring. What is the difference between partial-thickness and full-thickness skin loss? Partial-thickness skin loss involves only the epidermis and part of the dermis, while full- thickness skin loss extends through the entire dermis and into subcutaneous tissue or deeper. 4 What does erythema in a wound site indicate? Erythema indicates increased blood flow and possible inflammation, which may suggest infection or irritation. Why is it important to assess the wound's exudate? Exudate can provide vital information about the wound’s
