The Effect of Sweet Orange Aromatherapy on Anxiety and Pulse Level of Nurse Students

This randomized controlled study examined the effect of sweet orange essential oil aromatherapy on reducing anxiety experienced by nursing students during the IV cannulation process. First-year nursing students from a university in eastern Turkey participated in the study. According to the sample size determined by G\*Power analysis, 100 students were randomized, and the study was completed with 47 students in the experimental group and 48 students in the control group. All students were taught IV cannulation skills theoretically and practically. Subsequently, students in the experimental group performed IV cannulation on real patients after receiving aromatherapy. Data were collected using a Personal Information Form, a Pulse Monitoring Form, and the State-Trait Anxiety Inventory (STAI).
