A nurse is caring for a client who has generalized anxiety disorder and is taking buspirone. The nurse should identify that which of the following outcomes is an advantage of buspirone?

Choice A reason: Buspirone does not provide rapid relief of anxiety. Its therapeutic effect is delayed because it works by modulating serotonin (5-HT1A) receptors rather than producing immediate central nervous system depression. Clinical improvement typically occurs after 1 to 3 weeks of continuous use. Therefore, relief of anxiety within 30 minutes is characteristic of benzodiazepines, not buspirone. Choice B reason: Gastrointestinal disturbances such as nausea, dizziness, headache, and abdominal discomfort are relatively common adverse effects of buspirone, particularly during early treatment. These effects are dose related and may diminish over time, but they are not considered rare, making this option incorrect. Choice C reason: Buspirone does not cause physical dependence, tolerance, or withdrawal symptoms. Unlike benzodiazepines, it does not act on gamma-aminobutyric acid (GABA) receptors and therefore lacks sedative, muscle-relaxant, and addictive properties. This makes buspirone a preferred option for long-term management of generalized anxiety disorder, especially in clients with a history of substance use disorder. Choice D reason: Buspirone has no sedative or hypnotic properties and does not promote sleep. It is ineffective as a nighttime sedative and should not be used for insomnia. Clients requiring sleep aids would need medications specifically indicated for sleep disturbances.
