In alignment with the selected research approach and the research philosophy, the data collection tools were chosen for this study.To be noted precisely, the key intent of this research is to assess the differences in care giving procedures used by senior nurses and junior nurses on the basis of their knowledge levels and experience. In accordance, data regarding nurses’ knowledge on post PCI care was collected by means of primary research through questionnaires. The questionnaires were designed with close-ended questions to allow better convenience to the nurses when responding. Moreover, as the information needed was qualitative in nature, the close-ended questions helped to keep the responses precise, direct and comprehensive, without raising unnecessary complexities.
The questionnaires were distributed among 5 senior nurses and 5 junior nurses in the CCU department of a Hong Kong based healthcare centre. As it is likely that nurses in the CCU department have busy schedules and would face inconveniences in answering questions in details, the questions were organized in a close-ended manner.The nurses were selected using the systematic sampling method. The senior nurses included nursing professionals with at least 3 years of experience in the field, while the junior nurses were categorized as professionals who have been serving post PCI patients since one year after graduation.
In accordance, the questionnaire was constructed with 10 questions, each posing a different situation for the nurses to respond. For example, question 1 intended to learn the duration for which a patient, in their post PCI phase, should stay in complete bed rest. The obtained response to this question, which will be elaborated in the next chapter of this dissertation, revealed the perception and understanding of the nurses (both junior and senior nurses separately) to the general norm of practice. Other questions, similarly directed to the nurses’ responses in different situations or problems, commonly witnessed with post PCI patients.
