A nurse is collecting data from a client following the application of a leg cast for the treatment of a fracture. Which of the following findings should the nurse expect to find first if the cast is too tight?

A. Cool toes indicate impaired circulation, but this usually occurs after edema develops. B. Edema of the toes is often the first sign that a cast is too tight, as swelling occurs distal to the cast and may progress to compromise circulation and nerve function. C. Inability to move toes is a later sign indicating severe neurovascular compromise. D. Pallor also indicates compromised circulation, which occurs after swelling has already begun.
