The growing global instability has increased the demand for healthcare and disaster response skills among registered nurses (RNs). However, research shows that RNs are not sufficiently prepared for disaster situations. Although RNs are responsible for managing injuries during armed conflicts in accordance with International Humanitarian Law (IHL), nursing education lacks specific training in this area. A national survey revealed that only two universities in Sweden offer IHL-related education for nursing students. These findings highlight the urgent need to revise nursing education in Sweden to better prepare RNs for the challenges posed by global crises, including armed conflicts.
