Final answer:
A syringe is typically used for venipuncture in pediatric patients to accommodate their smaller and more delicate veins.
Step-by-step explanation:
The syringe method is most often used for venipuncture in pediatric patients. This is due to the smaller veins in children, which may make traditional venipuncture more challenging. The use of a syringe allows for more gentle and controlled drawing of blood, reducing the risk of harming the smaller and more delicate veins typical in pediatric patients.
