This unit of study is a core unit for students completing the Master of Nursing (Nurse Practitioner) and aims to prepare students to develop the knowledge and skills to conduct an advanced assessment and make an appropriate diagnosis as part of advanced and extended nursing practice. Diagnostic reasoning is the hallmark of an expert nurse practitioner. The ability to gather and judge the value of perceptual and clinical information to inform choices and provide benefit to patients with minimal risk of harm is at the heart of advanced practice nursing. Nurse practitioners are required to make effective practice decisions and use informed judgement, frequently in the context of uncertainty and for patients with complex health problems. Nurse practitioners are required to use effective communication strategies, including cross-cultural communication, with inter-professional colleagues, patients and the broader community. Students will undertake a period of supernumerary integrated professional practice (SIPP) (60 hours) verified by their approved supervisor concurrently while undertaking this unit of study.
