This study examined South Korean pregnant women's workplace experiences through Meleis' transition theory. Twenty participants engaged in online focus groups, discussing pregnancy, childbirth, prenatal care, and COVID-19 concerns. Content analysis revealed 15 themes reflecting transition theory's components. Participants were mostly first-time mothers in their second trimester. Transition facilitators included supportive family and health checks, while inhibitors comprised workplace stress and COVID-19 risks. Transition responses included worries about delivery pain and infant expectations. Nursing interventions recommended encompassed diet, exercise, and psychological support. The findings suggest health care providers should understand and address these transitions with tailored prenatal interventions.
