pressure injury - Nursing Case Study
Pathophysiology
• Primary mechanism: Pressure injuries occur primarily due to sustained pressure on the skin and underlying tissues, which compresses blood vessels and reduces blood flow. This deprives tissues of oxygen and nutrients, leading to cell death and ulcer formation.
• Secondary mechanism: Friction and shear further exacerbate tissue damage. Friction occurs when the skin moves against a surface, while shear involves deeper tissue layers sliding over each other, causing additional strain and damage to blood vessels.
• Key complication: If untreated, pressure injuries can lead to infection, as the open wound provides an entry point for bacteria, potentially resulting in more severe health issues.

Initial Assessment Findings:
During the initial nursing assessment, the patient, a 72-year-old retired school teacher, was observed to have a Stage 1 pressure injury over the sacral area, characterized by persistent redness that does not blanch when pressure is applied. The skin was intact, with slight warmth and mild edema, but no open sores or signs of infection were present. The patient reported mild discomfort, rating it as a 3 out of 10 on the pain scale, which she described as a constant, dull ache. She expressed concern about the pressure injury due to her history of Type 2 Diabetes, which can complicate wound healing.
In addition to the sacral assessment, the nursing team conducted a thorough skin inspection and noted no other areas of concern. Her Braden Scale score was assessed at 16, indicating a mild risk for pressure injury development. Given her stable vital signs—blood pressure 130/80 mmHg, heart rate 78 bpm, respiratory rate 16 breaths/min, temperature 98.6°F, and oxygen saturation 98% on room air—there was no immediate indication of systemic infection. The patient's mobility was limited; she reported spending significant time seated or lying down, which could contribute to the pressure injury. Her nutritional status was evaluated, and while she maintained a balanced diet, her recent weight loss was noted as a point for further monitoring.
The nursing plan focused on implementing preventive measures to alleviate pressure and promote healing. This included regular repositioning every two hours, using pressure-relieving devices such as a special mattress overlay, and educating the patient on the importance of shifting positions frequently. Additionally, the team planned to consult with a dietitian to ensure optimal nutritional support and to monitor blood glucose levels closely, as stable glucose control is crucial for wound healing in diabetic patients. These interventions aimed to reduce pressure on the sacral area, prevent progression of the injury, and promote recovery.

Response to Interventions:
One week into the implementation of the nursing care plan, the patient showed notable improvement in the management of her Stage 1 pressure injury. Regular repositioning every two hours, along with the use of a pressure-relieving mattress overlay, helped alleviate pressure on the sacral area. The persistent redness had decreased significantly, and the skin appeared less warm and swollen, indicating that the interventions were effective in preventing further skin breakdown. The patient reported a reduction in discomfort, now rating her pain as a 1 out of 10, describing it as a mild, intermittent ache. This improvement in her symptoms reflected the positive impact of the nursing interventions on her pressure injury.
Additionally, the consultation with the dietitian resulted in a tailored nutritional plan that emphasized adequate protein and calorie intake to support wound healing. The patient’s dietary modifications, combined with vigilant blood glucose monitoring, contributed to stable blood glucose levels, averaging 110 mg/dL. Her recent weight loss appeared to stabilize, and she began to regain some of the weight, indicating enhanced nutritional status. This progress was encouraging, as proper nutrition and glucose control are crucial for optimal recovery, particularly given her history of Type 2 Diabetes.
While the initial response to the interventions was positive, the nursing team remained vigilant, continuing to monitor the patient’s skin integrity closely. Education efforts were reinforced, reminding the patient and her caregivers about the importance of regular position changes and skin care routines. The patient expressed satisfaction with her care plan and remained engaged in her recovery process, understanding that ongoing adherence to preventive measures would be essential to maintain her progress and prevent new complications. As the patient’s journey continued, the focus would remain on sustaining these improvements and addressing any potential areas of concern proactively.

Two weeks into the care plan, the patient's situation took a slight turn, highlighting the importance of continued vigilance. Although her Stage 1 pressure injury had shown substantial improvement, a new challenge emerged. During a routine skin assessment, the nursing staff noticed faint pink discoloration and a slight increase in warmth over the patient's right heel, suggesting the early signs of another pressure injury. The patient's mobility limitations, compounded by her pre-existing condition of Type 2 Diabetes, necessitated intensified preventive measures to address this new concern promptly.
Vital signs remained stable, with blood pressure at 128/76 mmHg, heart rate at 72 beats per minute, and respiratory rate at 16 breaths per minute. However, her fasting blood glucose had slightly increased to 125 mg/dL, prompting a review of her dietary adherence and potential adjustments to her nutritional plan. The nursing team responded by incorporating additional heel elevation using specialized heel protectors and reinforcing the importance of frequent, gentle heel checks during position changes. Education efforts were doubled, emphasizing the patient's role in diligent self-monitoring for any changes in skin condition.
This new development underscored the need for proactive adaptation of the care plan. The nursing team collaborated with the interdisciplinary team to ensure comprehensive support, including possible updates to her physical therapy regimen to enhance mobility. The patient remained engaged and cooperative, expressing understanding and a commitment to following the revised recommendations. This situation provided an opportunity for the nursing team to demonstrate foundational skills in pressure injury prevention and patient education, ensuring that the patient would continue her recovery journey with minimal setbacks.

Response to Interventions
Over the following week, the nursing team's intensified focus on preventive measures began to yield positive results. The heel protectors were proving effective; during subsequent skin assessments, the faint pink discoloration on the patient's right heel had noticeably faded, and the warmth had diminished, indicating that the early-stage pressure injury was being successfully managed. The patient's engagement in her care plan was crucial, as she adhered to the recommended heel checks and collaborated closely with her caregivers.
The dietary adjustments made to address her slightly elevated blood glucose levels were also successful. Her fasting blood glucose stabilized at 110 mg/dL, reflecting improved adherence to the nutritional plan crafted by the dietitian. This highlighted the importance of an interdisciplinary approach, where the combined efforts of nursing, dietary, and physical therapy teams resulted in holistic care that not only addressed the pressure injury but also managed her diabetes more effectively.
Throughout this period, the patient reported a renewed sense of confidence and comfort, expressing gratitude for the comprehensive care she received. Her mobility showed slight improvement, allowing for more frequent position changes, which further reduced the risk of pressure injuries.
