A. Self-care deficit might apply if the client is unable to perform foot care independently. However, the priority concern is addressing the potential complications of neuropathy, such as skin breakdown, before considering assistance with care.
B. Risk for infection is a valid concern, especially if skin integrity is compromised. However, infection prevention depends on maintaining intact skin, making skin integrity the more immediate priority.
C. Impaired physical mobility may contribute to challenges in foot care but does not directly address the risk posed by neuropathy, which primarily affects sensory perception and increases vulnerability to unnoticed injuries.
D. Risk for impaired skin integrity is the priority because neuropathy reduces sensation in the feet, increasing the likelihood of unnoticed injuries, pressure sores, or burns. Early identification and prevention of skin damage are essential for avoiding complications.
