A nurse is providing care to a client who is aggressive and demonstrating self-injurious behaviors. Which of the following disorders does the nurse identify as being consistent with this behavior?

Choice A reason: Obstructive sleep apnea causes interrupted breathing during sleep, leading to fatigue, irritability, and potential cognitive impairment. While chronic sleep disruption may contribute to mood changes, it is not typically associated with aggressive or self-injurious behaviors. These behaviors are more characteristic of neurodevelopmental or psychiatric disorders, making sleep apnea an unlikely primary cause in this scenario, as it primarily affects sleep quality and daytime alertness. Choice B reason: Insomnia involves difficulty falling or staying asleep, which can lead to irritability, fatigue, and emotional dysregulation. However, it is not directly linked to aggressive or self-injurious behaviors, which are more commonly associated with neurodevelopmental conditions like autism or psychiatric disorders. Insomnia may exacerbate underlying issues but is not a primary cause of such behaviors in this context. Choice C reason: Autism spectrum disorder is characterized by challenges with social communication, sensory sensitivities, and emotional regulation, which can manifest as aggression or self-injurious behaviors, particularly under stress or sensory overload. These behaviors may occur due to difficulties processing emotions or environmental stimuli, making autism a likely diagnosis for the client’s presentation, requiring targeted behavioral and therapeutic interventions. Choice D reason: Narcolepsy involves excessive daytime sleepiness and sudden sleep attacks due to dysregulation of sleep-wake cycles. It does not typically cause aggressive or self-injurious behaviors, as its primary symptoms are related to sleep disturbances. These behaviors are more aligned with neurodevelopmental or psychiatric conditions, ruling out narcolepsy as a likely cause of the client’s aggressive and self-injurious actions.
