Problem: While the educational preparation of students in a tertiary nursing programme was the general focus of the study, the specific concern was with the degree to which students in the first and third year of the programme implemented all aspects of the nursing process in their delivery of patient care. The study developed out of a need to evaluate the effectiveness of theoretical teaching in regard to the students' ability to implement theoretical principles in clinical practice. The desired outcome of the study is that the data will be useful in developing more appropriate and effective teaching approaches that will result in improved clinical nursing practice. Methodology A survey of patients receiving nursing care from students in the first and third year of their programme was conducted on completion of a one week block of clinical experience for both groups of students. A questionnaire was the instrument of data collection. Factors included in the study were the patients' perceptions of the students' attention to four of the five phases of the nursing process: assessment, diagnosis, planning and evaluation. Questions addressing the degree of patient involvement in all of these phases were included throughout the questionnaire. Questionnaires were returned from twenty nine of the thirty one patients surveyed in the first year student group and from thirty of the thirty one patients surveyed in the third year student group; constituting a 93.5 percent and a 96.7 percent response respectively. Results The scores achieved by each group of students were compared against scores determined by the researcher to indicate realistic educational and professional standards of practice in each specified section and comparisons were also made between the two students groups to identify development of practice over the education programme. Scores indicated that: 1. Within each section of the study both student groups scored below the expected level on certain items, the most notable deficiencies being related to the aspects of patient empowerment through informing and involving. 2. The third year student group scored overall higher than the first year students in regard to attention to the more 'technical' aspects of the nursing process, but did not give the same degree of attention to the 'human' aspects, scoring equal to, or lower than their less experienced colleagues. Conclusions: 1. There are apparent philosophical differences between the graduates of the 'old style' training system and those involved in the tertiary nursing programme in regard to the individualization of patient care and the allocation of priorities within a time frame. 2. Clinical application of theoretical principles relies heavily on the reinforcement of these principles by the clinical teacher/supervisor. There is a need for these clinical supervisors to have: (a) a better understanding of the educational objectives for students in the clinical settings, and (b) assistance towards developing teaching/organizational strategies that will guide the student towards objective attainment when such abilities are not developed. Recommendations: Among the recommendations presented were: 1. that the nursing discipline within the university make formal and informal opportunities to inform all clinicians of the changes in nursing education and the implications these changes have on the overall approach to the delivery of patient care. 2. that there is an increased emphasis on the educational preparation of the clinical supervisors and that their commitment to the students' achievement of the clinical objectives is enhanced through involvement in programme planning and evaluation.
