Since nurses come across patients from diverse cultures, cultural intelligence is reflected as an imperative competence for nurses. Pioneer healthcare organizations have a duty to enhance the professional nurses’ competencies.

To examine how cultural intelligence relates to nurses' perceptions of their own professional competencies.

The study was carried out in in all in-patient care units at Shoubrakhit General Hospital.

All of the 460 registered nurses who met the inclusion criteria, had worked in the study's allocated settings for at least six months, and were available at the time of data collection were included. They indicated a willingness to take part in the study.

two tools were used. Tool one: “the Cultural Intelligence Scale (CQS)". Tool two: “Competency Inventory for Registered Nurses (CIRN)".

The findings indicated that nurses have a moderate level of professional competence and cultural intelligence. Additionally, the results demonstrated a statistically significant positive correlation between educational level, nursing experience, and working units and professional competence as well as cultural intelligence. 

Cultural intelligence and professional competences have a strong positive significant association that is statistically significant positive correlation.

training sessions should be undertaken to enhance cultural intelligence and professional nursing competencies throughofficial and unofficial training of nurses’ cognitive and behavioral skills. Hospital and nurse managers along with all nurses should perform a cultural competence self-assessment periodically to determine own strengths and weaknesses. Nurses should be rewarded and motivated for obtaining continuous education certificates in cultural competence. Nurses should develop communication and language barriers as language is the key to accessing any cultural values, beliefs, and viewpoints. Online networking and social media can have a great influence on cultivating nurses’ cultural competency and awareness and keeping them up-to-date with cultural competency concerns.
