What is an important step before performing a venipuncture on a child with hemophilia?

Having emergency equipment readily available is crucial before performing a venipuncture on a child with hemophilia because these patients have a bleeding disorder that impairs their ability to form clots. In the event of excessive bleeding, being prepared with the necessary tools—such as pressure bandages, hemostatic agents, and access to intravenous fluids—can be vital for managing potential complications.

In hemophilia, the risk of prolonged bleeding after procedures like venipuncture is significant, so having emergency resources at hand ensures healthcare providers can address any bleeding quickly and effectively. This preparedness is essential for ensuring the child's safety during and after the procedure.

Other options do not prioritize the immediate safety concerns associated with potential bleeding. Notifying the laboratory technician or ensuring adequate hydration, while beneficial in certain contexts, do not address the immediate response required for managing a bleeding complication. Applying a tourniquet for an extended time is generally not advisable as it could further complicate the situation and might even lead to vascular injury or affect blood flow.
