Nursing students have traditionally experienced difficulties with the science subjects in nursing curricula, and irrespective of the institution conducting a nursing programme, this trend appears to be continuing. A satisfactory means of predicting academic performance in these subjects will facilitate the development of educational strategies designed to assist students overcome their difficulties. In this study, an instrument called the Self-Efficacy for Science (SEFS) was developed and tested. The SEFS was designed to predict academic performance in the science areas of a first-year undergraduate nursing course. A cohort of first-year students enrolled in a bachelor of nursing course were surveyed by questionnaire. Students' academic scores for two first-year science subjects were obtained and used as the criterion measure for the study. Principal component factor analysis revealed the SEFS contained six instead of the hypothesized four factors. These six factors could explain 70% of students' self-efficacy for science. Cronbach alpha of the SEFS was 0.9. The SEFS could predict 24% of the cohort's academic performance in a physical science subject and 18.5% for a bioscience subject. Studying science in the final year at high school was not statistically significantly related to the SEFS. Implications for students and future research are discussed.

The whistleblowing nurses believed they were acting in accordance with a duty of care. There is a need for greater clarity about the role nurses have as patient advocates. Furthermore, there is need to develop clear guidelines that create opportunities for nurses to voice concerns and to ensure that healthcare systems respond in a timely and appropriate manner, and a need to foster a safe environment in which to raise issues of concern.

Working more than 16 hours per week had a detrimental impact on the academic performance of nursing students. More importantly, this study shows that nursing-related employment is not advantageous to students' academic performance, even for a nursing practice-based subject. If the current practice of employing nursing students in clinical settings is to continue, this experience needs to be aligned to the academic curriculum if it is to be beneficial to students' knowledge and skill acquisition.

Nursing plays a key role in maintaining practice standards and in reporting care that is unacceptable although the repercussions to nurses who raise concerns are insupportable. Overall, whistleblowing and how it influences the individual, their family, work colleagues, nursing practice and policy overall, requires further national and international research attention.
