A nurse must respond to client telephone messages. Which client's report should be addressed first?

The appropriate choice for prioritizing the client's report is a case of a client with a right leg cast reporting tingling in the right foot. This report suggests a potential complication related to the cast, specifically concerning circulation or nerve compression. Tingling in the extremities can indicate inadequate blood flow or nerve issues (such as compartment syndrome), both of which require immediate attention to prevent further complications or permanent damage.

In a healthcare setting, assessing and addressing concerns related to circulation or nerve function is essential, as prompt intervention can significantly impact the client's overall health and recovery. Tingling sensations demand urgent evaluation to ensure that therapy or adjustments, such as a cast modification, can be carried out swiftly.

While other options represent notable concerns—like nausea from medication and vomiting after insulin, which could indicate issues like medication side effects or insulin management challenges—tingling in the foot carries a higher risk for serious complications, thus warranting it the highest priority.
