REx-PN
Repeated epistaxis, gum bleeding, easy bruising, heavy menstrual bleeding, or prolonged bleeding after dental work points toward a problem forming the first platelet plug. In von Willebrand disease, the abnormal or insufficient protein is von Willebrand factor (VWF): it anchors platelets to injured vessel walls and carries factor VIII in the circulation. That single defect explains why mucosal bleeding is typical and why factor VIII may also be reduced. For an RPN, three questions set the priority: does the bleeding pattern fit impaired primary hemostasis, is the patient currently losing blood, and is the proposed treatment safe for this VWD type? A stable patient needs focused history and hematology-directed testing. A patient with major or life-threatening hemorrhage needs VWF-containing concentrate and hemophilia treatment centre guidance without waiting for confirmatory testing.
