Buspirone hydrochloride is prescribed for a client diagnosed with an anxiety disorder. The nurse providing instructions should inform the client about which characteristic of this medication?
- A. There is risk of addiction.
- B. Dizziness and nausea may occur.
- C. Tolerance can occur with the medication.
- D. The medication can produce a sedating effect.
Correct Answer: B
Rationale: Buspirone hydrochloride is used in the management of anxiety disorders. The medication has a more favorable side effect profile than do the benzodiazepines. Dizziness, nausea, headaches, lightheadedness, and paradoxical central nervous system excitement, which generally are not major problems, are side effects of the medication. The advantages of this medication are that it is not addicting, tolerance does not develop, and it is not sedating.
