Background In the dynamic landscape of healthcare, nurses play a crucial role as ethical stewards, responsible for whistleblowing, nurse advocacy, and patient safety. Their duties involve ensuring patient well-being through ethical practices and advocacy initiatives. Aim This study investigates the ethical responsibilities of nurses regarding whistleblowing and advocacy in reporting concerns about patient safety. Research Design A cross-sectional study utilized cluster and simple random sampling to gather a representative sample of actively practicing registered nurses. Data collection involved a demographic form, Nurse Whistleblowing Intentions Scale, Nursing Advocacy Scale, and Clinical Decision-Making Scale. Participants and Research Context The study utilizing a robust sample size determination formula for reliable findings included 96 diverse nurses, predominantly females. Engaged actively in direct patient care across various outpatients clinics. The recruitment process specifically sought individuals with expertise in safety protocols and reporting, contributing to a nuanced understanding of the study’s focus. Ethical Considerations Ethical approval was obtained from the ethics committee of the university and the hospitals involved. Written consent was obtained from the participants. A thorough ethical review was conducted to guarantee participant protection and adherence to ethical principles. Results Surveyed nurses demonstrated positive whistleblowing (Overall Mean Score: 3.58), high advocacy (Overall Mean Score: 12.2), and nuanced ethical decision-making for patient safety (Overall Mean Score: 15.78). Demographic factors, such as nationality and ethical training, significantly impacted whistleblowing intentions, while age, gender, and ethical training correlated with nursing advocacy behavior. Associations with experience and qualification emerged in ethical decision-making. Conclusion The gained insights foster targeted interventions, improving ethical practices, advocacy, and informed decision-making in nursing. This study explores the intricate link between demographics and ethical considerations among surveyed nurses, acting as a catalyst for ongoing initiatives to strengthen the ethical foundation in healthcare sector.
