Chapter 27: Anger, Aggression & Violence Management

Due to their direct patient contact, nurses are frequently targets of violence, especially in emergency, psychiatric, geriatric, and intensive care units. The chapter explores the complex etiology of aggression, including biological risk factors such as genetic predispositions (e.g., the MAOA gene), neurobiological factors related to the limbic system (specifically the amygdala, hippocampus, and hypothalamus), and the role of neurotransmitters like serotonin and dopamine. Cognitive theories suggest that anger and aggression often stem from learned behaviors, threats to one’s values, or feelings of losing control. The nursing process begins with assessment, recognizing that a patient's history of violence is the single best predictor of future episodes, and identifying specific escalation signs such as hyperactivity, pacing, and rigid posture. Crucial implementation strategies prioritize patient and staff safety, emphasizing the development of trust through brief, nonthreatening interactions, utilizing deescalation techniques, and ensuring an escape route for the nurse. Interventions are tailored based on coping ability; patients with healthy coping skills who are overwhelmed benefit from validation and collaborative problem solving, while those with marginal coping require clear communication, reduced ambiguity, and predictable routine. For patients with cognitive deficits, such as delirium, nurses should simplify the environment and use validation therapy to address the feelings underlying their agitation, rather than relying solely on reality orientation. When all less restrictive measures fail, seclusion or mechanical restraints may be required, but these must be used only to prevent harm and require strict monitoring and prompt debriefing for both staff and patient afterward. Pharmacological management includes acute use of antipsychotics (like haloperidol or olanzapine) and benzodiazepines (like lorazepam), while long-term management focuses on treating the underlying psychiatric disorder with medications such as SSRIs or mood stabilizers.
