A case manager in a mental health facility is reviewing the medical records of a group of clients. Which of the following clients should the case manager identify as having the greatest risk of accident and injury?

Introduction: Delirium is characterized by an acute disturbance in cognition and fluctuating consciousness, leading to severe disorientation and psychomotor agitation that places the client at high risk for falls and accidental trauma. A. A client with obsessive-compulsive disorder (OCD) typically experiences significant anxiety and distress related to obsessions and compulsions. While these behaviors are time-consuming and emotionally taxing, they do not generally impair consciousness or motor coordination in a way that creates an immediate high risk for physical accidents or injuries. B. A school-age child with a tic disorder experiences sudden, rapid, non-rhythmic motor movements or vocalizations. While tics can be socially distressing or physically uncomfortable, they do not usually cause the profound disorientation or loss of environmental awareness necessary to be categorized as the greatest risk for injury. C. A gambling disorder is a behavioral addiction characterized by persistent and recurrent problematic gambling behavior. This condition leads to significant financial, social, and psychological consequences, but it does not involve the acute physiological or cognitive impairments that would lead to physical accidents in a clinical setting. D. An adolescent with delirium is at the greatest risk for injury due to the acute onset of confusion, impaired judgment, and potential hallucinations. Delirious clients often attempt to pull out invasive lines, wander into unsafe areas, or misinterpret environmental stimuli, making constant monitoring and safety interventions a priority.
