The fourth edition of A Guide to Mental Health and Psychiatric Nursing was released in 2016 for BSc Nursing students with subsequent reprints reflecting minimal syllabus changes. However with updates to the curriculum and the adoption of the WHO ICD-11 a new edition became necessary. This edition aligns with the revised syllabus offering enhanced learning aids like visual illustrations and case studies. Additional resources such as online support resources such as Audio पाठ Shala Viva-Voce and additional MCQs have been introduced to enhance student engagement. and updated content includes the Mental Health Care Act (MHCA) 2017 Protection of Children from Sexual Offences (POCSO) Act and nurses' roles in implementing MHCA 2017 aims to prepare students for academic challenges and ensure safe and quality patient care.
