To generate a descriptive theory framework regarding the experiences of the cultural competencies among clinical nurses in Taiwan. With the advances in, and the easy accessibility to health care services, frontline nurses require a higher cultural competence to perceive and satisfy the needs of the culturally diverse patients. A qualitative approach using a grounded theory was applied. There were 30 nurses recruited by purposive sampling. 'Unprepared when encountering different cultures' was the core theme for describing and guiding the process of examining the nurses' experiences with a cultural competence. 'Awareness of value differences' was identified as the antecedent condition. The nurses revealed that they have had difficulty implementing their nursing work and seeking resources that represented situations in which interactive behavioral characteristics appeared to improve their cultural competencies. The nurses managing different cultural situations ultimately learned to tolerate the different cultures and to give patients culturally appropriate care, which thereby enhanced the care quality. This study highlights the multiple layers of cultural competence experienced by the nurses and the understanding of cultural diversity among patients and caregivers. These results will assist the healthcare providers by offering references for clinical healthcare based on the patients' subjectively different cultural perspectives. Medical organizations should design an in-service educational program/instructions concerning culture to help strengthen the nursing specialists' relevant cultural competencies, to meet the individual patients' cultural care needs, and thereby boost the clinical care quality.

The quality of nurses’ work has a direct effect on patient health, and poor sleep has been positively associated with nurses’ medical errors. The aim of this study was to investigate the relationship between quality of sleep and heart rate variability (HRV) among female nurses. A descriptive cross-sectional correlational study design was used in January 2014 to study female nurses (n = 393) employed in a medical center in Taiwan. Data were obtained from several questionnaires. HRV was analyzed with five-minute recordings of heart rate signals obtained using a Heart Rater SA-3000P. Approximately 96% of the participants self-reported a poor quality of sleep. Compared to non-shift nurses, significant decreases were found in total power (TP) and low-frequency HRV among shift-work nurses. However, negative correlations were found between sleep quality and HRV, including total power, low frequency, and the low frequency/high frequency ratio (r = −0.425, p < 0.05; r = −0.269, −0.266, p < 0.05). In a stepwise multiple regression analysis, 23.1% of variance in quality of sleep can be explained by TP and heart rate. The sleep quality of female nurses was poor and this affected their autonomic nervous system, which can contribute unfavorable consequences for their health.
