Medio-legal issues apply to each and every patient interaction that we have as registered nurses and healthcare professionals. The Nursing and Midwifery Council (NMC) Code of Conduct (2018) is concise on how we should keep up to date, document carefully, and work within our scope of practice — just to name a few pointers. Here, Kirsty Armstrong, advanced nurse practitioner in out-of-hours and urgent care, provides a crossword containing some further items that nurses need to consider when working with patients, with explanation provided with the answers. The list does not encompass everything that nurses need to be mindful of, but hopefully is a starting point for further reading, for which a list of resources is provided at the end of the article. This crossword has a focus on immunisation practice.
