Nurse Practitioners are a senior type of practice nurse, who assist on all levels of patient care, usually within a GP surgery – they are able to diagnose, refer and (often) prescribe treatment
Practice nurses work in GP surgeries where they plan and provide nursing care, treatment and health education to patients of all ages.
