The goal of this clinical trial is to evaluate whether using two different types of balls can reduce pain and anxiety during venipuncture in school-aged children (7-12 years) in a pediatric emergency setting. The main questions it aims to answer are:

Does squeezing a soft ball or a textured (ridged) ball during venipuncture reduce perceived pain compared to a control group? Does squeezing a soft ball or a textured (ridged) ball during venipuncture reduce situational anxiety compared to a control group?

Researchers will compare the soft ball, textured ball, and control groups to see if the type of ball affects children's pain and anxiety levels.

Participants will:

Complete a demographic and clinical information form. Use Wong-Baker Faces Pain Rating Scale (WBS) and Child Anxiety Scale-State (ÇAS-D) to report pain and anxiety before, during, and after venipuncture.

Squeeze either a soft or textured ball during venipuncture (for experimental groups) while control group children receive standard care without distraction.
