Ethical conflicts arising from medical practice, particularly in primary care, often remain underestimated. Our study aims to examine how ethics is embedded in nurses' practice, while exploring their ethical reflections to resolve dilemmas encountered during care. This study adopted a descriptive approach targeting nurses, within the university hospitals of Sfax. A pre-established questionnaire was used as the instrument. Data collection took place over a one-month period, from December 1, 2023 to December 30, 2023.We identified 74 participants. Most of them were reported as being frequently confronted with ethical dilemmas on a daily basis. The three concerns most frequently mentioned by participants in their practice were related to patient consent and the principle of autonomy, professional secrecy and situations of vulnerability. Our results revealed that they need ethical conduct to solve the problems they may face.
