Maneuver

Interventions/Control_1

Intervention group: The nurse facilitates attention redirection (distraction) through casual conversation. The nurse delivers the following standardized verbal prompts at each phase.

Application of the tourniquet: "I am going to apply a tourniquet to help visualize your vein. Please make a fist with your thumb tucked in."

Disinfection and selection of the puncture site: "Did you sleep well last night? / Is there anything you are having trouble with during your hospital stay?"

During needle insertion and blood collection: "Do you remember what you ate last night? / Were there any hospital meals that you particularly enjoyed? / Are you able to eat? / Is the seasoning to your taste? / What topics have you been talking about most recently during visits or phone calls? / Have you noticed any changes in how you are feeling physically?"

Needle removal and hemostasis: "We're finished. Thank you for your cooperation. Please wait a moment until the bleeding stops."

Interventions/Control_2

Control group: Blood collection is performed according to the standard procedure, with only routine explanations related to venipuncture. In each phase, the nurse provides only the following standardized information, and no casual conversation (distraction) is conducted.

Application of the tourniquet: "I am going to apply a tourniquet to help visualize your vein. Please make a fist with your thumb tucked in."

Disinfection and selection of the puncture site: "We will collect blood from this site. / I'm going to disinfect the area where the needle will be inserted, so it may feel cold."

During needle insertion and blood collection: "I am going to insert the needle now, so it may be painful. If you feel strong pain or a tingling sensation like an electric shock, please let me know immediately. The needle has been inserted - did you feel any pain or numbness?"

Needle removal and hemostasis: "We're finished. Thank you for your cooperation. Please wait a moment until the bleeding stops."
