Nurses working in forensic psychiatric settings face unique challenges in practice, where they take on a dual role of custody and caring. Patient resistance is widespread within these restrictive settings and can take many forms. Perhaps the most disturbing form of resistance entails a patient's weaponization of their bodily fluids, with nurses as their target. The tendency in assigning motive for this act is to relegate to the psychopathology of the patient. This paper will adopt a poststructuralist perspective to reexamine this phenomenon as an act of resistance through the lens of Kristeva's concept of abjection. Patients confined in these settings have little sense of control, and in resistance may resort to the only thing available: their bodily fluids. By weaponizing the abject, patients actively violate and permeate the physical and psychological boundaries of nurses—the very boundaries considered crucial to safe and professional forensic psychiatric nursing practice. By recognizing this phenomenon as an act of resistance to confinement and loss of control, nurses may reorient their approach to care in forensic psychiatric settings.
