Patient education is defined as the process of influencing a patient’s behavior and helping them make the necessary changes to their knowledge, attitudes, and skills to maintain or improve their health. It is a crucial part of patient care, and the EHS ambulatory care healthcare system is giving patient education more importance. Many experts claim that nurses still have difficulties providing patient education because of a range of factors, which include a lack of expertise and numerous other obstacles. Moreover, there isn’t any published research that studies nurses’ attitudes, knowledge, and patient-teaching practices in primary healthcare in the United Arab Emirates. The research project aims to investigate the knowledge, attitude, and practice of patient teaching among nurses in primary health care centers to better understand how nurse knowledge and attitudes may affect nurse-performed patient education. The target population is nurses working in primary healthcare centers in Sharjah, Ajman, Dubai, Ras Al-Khaimah, Fujairah, and Umm Al Quwain. However, the sample size is 300 using a random cluster sampling technique. The participants were encouraged to take part in the study (KAPPTNQ) through an online survey. The study concludes that the majority of nurses are knowledgeable about patient education; a large proportion of the nurses have a positive attitude toward patient education; and the majority of the nurses have a positive practice of patient education. However, the major challenges nurses encounter with patients’ health teaching include language barriers, inadequate communication, ineffective time management, and cultural impacts on patient health education.
