Psychiatric nurses oversee the day-to-day operational activities of a psychiatric hospital. Positivity is one of the essential qualities of a psychiatric nurse. Nurses require emotional strength to cope with disrespectful patients who refuse medication or deny having a mental condition. In acute psychiatric institutions, depression and bipolar disorder are common diagnoses and treatments. Ten psychiatric nurses and ten nutritionists from public and private hospitals in and around Kolkata, West Bengal, participated in this qualitative study that relied on a purposeful sampling method. Telephonic interviews were scheduled based on responses to semi-structured surveys. Before beginning the discussions, informed consent was obtained. Only those who volunteered were deemed to be mentally at ease and keen to talk about their experiences. The coding analysis was performed using the Atlas ti-9 software, and the participants' opinions were tallied using networking, word cloud, and other methods. Results of participants’ perceptions show that mental health nurses have several responsibilities; one of the most important is maintaining a positive attitude. Most patients committed to acute psychiatric hospitals suffer from major depressive disorder, anxiety, or bipolar disorder. Despite a lack of research, some foods have been hypothesized to aid mental health. As a result, mental health facilities' nurses and dietitians encounter constant, unprecedented difficulties in their work. Besides, psychiatrists, nurses, and nutritionists face some of the most challenging patients in the hospital when working in mental wards. Overall, nurses and nutritionists need thorough training in dealing with adverse circumstances if their patients are to make full recoveries and enjoy their work.
