The aim of this study is to investigate senior nursing students' ethical sensitivity and fear of Covid-19 during clinical practice. This is a cross-sectional and relational study. The study has been conducted in June 2021 with senior nursing students at a university in the Central Anatolia region of Turkey (n=95). Data have been collected online via Google Forms by using a Nursing Student Characteristics Form, the Fear of Covid-19 Scale (FCV-19S), and the Moral Sensitivity Questionnaire (MSQ). The mean FCV-19S total score has been obtained as 17.93 (Sd=5.02) and median MSQ total score has been obtained as 96 (25th-75th percentiles=87-108). Students with previous Covid-19 infection had significantly higher FCV-19S scores (t=3.209, p=0.004). There were no significant differences in MSQ total or subscale scores based on the students' characteristics (p>0.05). FCV-19S total score was positively correlated with the holistic approach subscale of the MSQ (r=0.298, p=0.003). The results of this study have shown that senior nursing students had moderate levels of ethical sensitivity and Covid-19 fear. Previous Covid-19 infection has been associated with greater fear.
