A nurse is caring for a client that is immobile. The nurse recognizes that the appearance of non-blanchable erythema on the heels most likely indicates which of the following stages of pressure injuries?
Stage III pressure injury
Stage IV pressure injury
Stage II pressure injury
Stage I pressure injury
The Correct Answer is D
A. Stage III pressure injury
Stage III pressure injuries involve full-thickness skin loss, extending into the subcutaneous tissue but not through the fascia. These wounds typically present as deep craters and may involve undermining or tunneling. Non-blanchable erythema alone without visible skin loss is not characteristic of a Stage III pressure injury.
B. Stage IV pressure injury
Stage IV pressure injuries are the most severe and involve full-thickness tissue loss with exposed bone, tendon, or muscle. These wounds often have extensive tissue damage and can be difficult to manage. Again, non-blanchable erythema without visible skin loss is not indicative of a Stage IV pressure injury.
C. Stage II pressure injury
Stage II pressure injuries involve partial-thickness skin loss with damage to the epidermis and possibly the dermis. These wounds often present as shallow open ulcers or blisters and may have characteristics such as intact or ruptured blisters. While Stage II injuries can present with erythema, non-blanchable erythema specifically indicates a Stage I injury.
D. Stage I pressure injury
Stage I pressure injuries are the earliest stage and involve non-blanchable erythema of intact skin. The skin may be warmer or cooler than surrounding tissue and may have changes in sensation. There is no visible skin loss at this stage, but the area is at risk for further injury if pressure is not relieved. Therefore, non-blanchable erythema on the heels most likely indicates a Stage I pressure injury.

Correct Answer is A
Explanation
A. High-protein diet with vitamins and mineral supplements:
This choice indicates a good understanding of preventing pressure ulcers. High-protein diets are beneficial for tissue repair and wound healing. Adequate protein intake supports collagen synthesis, which is essential for maintaining skin integrity and healing wounds. Additionally, vitamins and mineral supplements can contribute to overall nutritional status and support tissue health.
B. Low-fat diet with whole grains and cereals and vitamin supplements:
While a low-fat diet and whole grains are generally healthy choices, they may not specifically address the needs of a patient at risk for pressure ulcers. Fat is important for skin health, and whole grains can contribute to overall nutrition, but protein and specific vitamins and minerals are more directly related to tissue repair and wound healing.
C. Vegetarian diet with nutritional supplements and fish oil capsules:
A vegetarian diet can be healthy, but it requires careful planning to ensure adequate protein intake, especially for tissue repair and wound healing. Nutritional supplements may help fill nutrient gaps, but specific attention to protein sources is crucial for preventing pressure ulcers. Fish oil capsules can provide omega-3 fatty acids, which may have some benefits for skin health.
D. Low cholesterol, high-fiber, low-carbohydrate diet:
This diet choice focuses more on cardiovascular health and weight management rather than addressing the needs of a patient at risk for pressure ulcers. While a balanced diet with adequate fiber can support overall health, protein intake and specific vitamins and minerals are more critical for skin integrity and wound healing.
Correct Answer is A
Explanation
A. There is no redness, warmth, or drainage at the insertion site.
This assessment is crucial for evaluating the status of the abdominal drain site. The absence of redness, warmth, or drainage suggests that the insertion site is healing well without signs of infection or inflammation. It indicates that the drain is functioning properly and that there are no immediate complications related to the drain insertion. This assessment directly addresses the goals related to monitoring the drain site for signs of infection or dysfunction.
B. Drainage from the surgical site is 30 mL less than yesterday.
Monitoring the drainage output from the surgical site is important to assess for changes in drainage patterns. A decrease in drainage volume may indicate reduced fluid accumulation at the surgical site, potentially reflecting improved healing and decreased need for drainage. However, while this assessment is valuable, it is not as directly related to assessing the status of the drain itself or evaluating complications at the insertion site as option A.
C. The patient reports adequate pain control with medications.
Pain control is an essential aspect of postoperative care, but it is not specifically related to assessing the functionality or complications of the abdominal drain. While pain management is important for patient comfort and recovery, it does not directly address the goals related to monitoring the drain site for signs of infection, leakage, or other complications.
D. Urine is clear yellow, and urine output is greater than 40 mL/hr.
While monitoring urine output and characteristics is important for assessing renal function and hydration status, it is not directly related to assessing the abdominal drain or its complications. Clear yellow urine and adequate urine output are generally positive indicators but do not provide specific information about the functionality or status of the drain.
