diabetes and diabetic foot ulcer - Nursing Case Study

Pathophysiology

• Primary mechanism: Diabetes leads to elevated blood sugar levels, which over time damage blood vessels and nerves, reducing blood flow and sensation, particularly in the feet.

• Secondary mechanism: Poor circulation due to damaged blood vessels slows healing and reduces the ability to fight infections, while nerve damage results in loss of protective sensation, increasing the risk of unnoticed injuries.

• Key complication: Diabetic foot ulcers may develop from minor injuries or pressure points, as the combination of poor healing, reduced sensation, and increased infection risk creates the perfect environment for ulcer formation.

Section 1

Initial Assessment Findings:

Upon initial assessment, the nursing team observes that the ulcer on the patient's left foot is approximately 1.5 cm in diameter with well-defined edges. The surrounding skin appears erythematous, and there is slight edema noted in the area, indicating localized inflammation. The ulcer base is moist and shows signs of granulation tissue, which is a positive indicator of the body's healing response. The patient reports mild pain, rating it as a 3 on a scale of 1 to 10, which is manageable with current interventions. Palpation of the area reveals warmth, but there is no purulent discharge or foul odor, suggesting that the ulcer is not currently infected.

The nurse performs a monofilament test to assess the patient's protective sensation in both feet. The patient shows diminished sensation in the left foot, particularly around the ulcer site, which aligns with the known complication of peripheral neuropathy due to diabetes. Capillary refill time is slightly prolonged at 3 seconds, indicating reduced circulation but not critically compromised. Pedal pulses are present but weak bilaterally, consistent with the patient's history of vascular issues. These findings emphasize the importance of continued monitoring and diligent foot care to prevent progression of the ulcer.

In light of these assessment findings, the care team discusses the importance of maintaining blood glucose control and optimizing foot care practices with the patient. The patient is educated on daily foot inspections, proper footwear, and the importance of adhering to prescribed medication and follow-up appointments. These foundational nursing interventions aim to promote healing of the ulcer and prevent potential complications, setting the stage for evaluating future progress and adjustments to the care plan as needed.

Over the next week, the patient adheres to the recommended care plan, which includes diligent foot care and blood glucose monitoring. During a follow-up visit, the nursing team reassesses the ulcer and notes positive changes. The ulcer now measures 1.2 cm in diameter, indicating slight reduction in size and suggesting that the healing process is progressing. The surrounding erythema has decreased, and the edema is notably reduced, signifying improved local inflammation control. The granulation tissue within the ulcer base appears more robust, which is a promising sign of ongoing tissue repair. The patient continues to report mild pain, now rated as a 2 out of 10, without any increase in severity.

The patient's blood glucose levels have become more stable, averaging between 110-130 mg/dL, reflecting better glycemic control.
