What laboratory test should be expected for a client with generalized petechiae and ecchymoses?

A complete blood count (CBC) is the appropriate laboratory test for a client presenting with generalized petechiae and ecchymoses. Petechiae and ecchymoses often indicate issues with blood clotting or platelet function, which can be effectively evaluated through a CBC. This test measures various components of blood, including red blood cells, white blood cells, and platelets. A low platelet count (thrombocytopenia) can lead to increased bleeding and bruising, thus explaining the presence of petechiae and ecchymoses.

In cases where generalized bleeding occurs, the CBC can provide valuable information about the overall health of the blood. It allows healthcare providers to assess parameters such as hemoglobin levels, hematocrit, and platelet count, helping to determine potential causes of the bleeding and guiding further diagnostic steps and necessary interventions.
