What indicates effectiveness of a platelet transfusion for a client?

The effectiveness of a platelet transfusion is indicated by a decrease in bleeding from puncture sites. When a patient receives a platelet transfusion, the primary objective is to increase the platelet count in the bloodstream to improve the blood's ability to clot and reduce bleeding. If bleeding from puncture sites, such as intravenous access points or other areas, diminishes after the transfusion, this indicates that the transfusion has successfully raised the platelet count and improved hemostatic function.

While an increase in white blood cell count, improved hemoglobin levels, and normalization of vital signs might be important for assessing overall health, they do not directly reflect the specific efficacy of platelet transfusions. The primary goal of administering platelets is to manage bleeding complications associated with low platelet levels, thereby making the reduction of bleeding the best measure of treatment effectiveness in this context.
