What should the nurse's priority action be when a client reports burning pain over the ankle three days after having a cast applied?

When a client reports burning pain over the ankle three days after having a cast applied, the priority action involves ensuring patient safety and addressing potential complications associated with casting. Reporting the client's complaint to the physician is crucial because new or worsening pain can indicate serious issues such as compartment syndrome, which is a medical emergency. This condition occurs when pressure builds up within a muscle compartment, leading to decreased blood flow and possible tissue damage.

By informing the physician, the nurse ensures that the client receives a timely evaluation and intervention. It is essential to respond quickly to any changes in the client’s condition, especially after a procedure that alters the anatomy, such as placing a cast. This approach allows for further assessment and potential imaging or treatments that may be necessary.

While applying ice or elevating the leg are supportive measures that might help with discomfort, they do not address the underlying concern of a potentially severe complication. Additionally, checking capillary refill and sensation in the toes is an important assessment to perform, but it should occur alongside notifying the physician. Thus, the priority lies in ensuring that the physician is aware of the client's report to facilitate further evaluation and care.
