During a screening on a patient with a recent cast on the left lower extremity, which of the following statements should the nurse be most concerned about?

The correct answer is B because pain in the left calf could indicate a potential neurovascular complication related to the casted extremity. It could suggest issues such as compartment syndrome or impaired circulation. Option A is not as concerning since not elevating the extremity may lead to swelling but is not an immediate concern. Option C indicates itching, which is common with casts and not as concerning as potential neurovascular issues. Option D, regarding arthritis in the wrists, is unrelated to the lower extremity issue being screened for.
