During a home visit, the nurse finds that an older adult client has amassed a large quantity of newspapers and magazines. When the nurse offers to remove some of the newspapers, the client becomes anxious. What disorder does the nurse suspect?

Reasoning: Choice A reason: Body integrity identity disorder (BIID), also referred to as body integrity dysphoria, is a rare and distinct psychiatric condition characterized by an intense and persistent desire to have a specific limb amputated or to be otherwise disabled, due to a perceived discrepancy between one's internal body schema and actual physical form. This disorder involves distorted perception of one's own body and has no clinical relationship to the accumulation of objects or anxiety triggered by removal of possessions. It is therefore not applicable to the clinical scenario described. Choice B reason: Body dysmorphic disorder (BDD) is classified within the obsessive-compulsive and related disorders spectrum in the DSM-5. It is characterized by a preoccupation with 1 or more perceived defects or flaws in physical appearance that are not observable or appear slight to others, leading to repetitive behaviors such as mirror checking or skin picking. BDD does not involve compulsive accumulation of objects, and the anxiety described in the scenario is specifically linked to the removal of collected items rather than any concern about physical appearance. Choice C reason: Hoarding disorder is a distinct DSM-5 diagnosis characterized by persistent difficulty discarding or parting with possessions regardless of their actual value, driven by a perceived need to save items and distress associated with discarding them. The accumulation of newspapers and magazines in large quantities and the marked anxiety triggered when removal is offered are classic clinical hallmarks of hoarding disorder. In older adults, hoarding behavior is particularly common and is associated with significant functional impairment, unsafe living conditions, and social isolation. The clinical presentation in this scenario is a textbook manifestation of hoarding disorder. Choice D reason: Oniomania, commonly known as compulsive buying disorder or shopping addiction, is characterized by excessive, uncontrolled, and repetitive purchasing behavior driven by the urge to shop rather than by need, leading to significant financial and psychosocial consequences. While it may share some features with OCD-spectrum disorders, oniomania involves the acquisition of items through purchasing, not the accumulation and inability to discard items already in one's possession. The described scenario involves retaining existing possessions, not compulsive purchasing, making this diagnosis incorrect.
