This article critically analyses the process of clinical decision-making (CDM) and associated theories that contribute to safe clinical judgement, allowing trainee advanced clinical practitioners (tACPs) to expand their knowledge, skills and attitude to CDM at an advanced level. The case included is from the author’s own clinical practice and is a reflective
piece involving CDM which embraces the four pillars of advanced practice. The relevant professional, legal and ethical issues that assist tACPs to follow the ‘Code of Conduct’ (Nursing and Midwifery Council [NMC], 2018) are also discussed in relation to this complex CDM case.
