A nurse is caring for a client who ingested a selective serotonin reuptake inhibitor and St. John's Wort. Which of the following findings should the nurse identify as being consistent with serotonin syndrome?

Rationale:A. Pill rolling movements and drooling are more characteristic of Parkinson’s disease rather than serotonin syndrome.B. Serotonin syndrome can present with autonomic instability such as dilated pupils, hyperthermia, and loss of muscle coordination due to increased serotonin levels.C. Tinnitus is not a common symptom of serotonin syndrome; jerking movements may occur but are not specific to this condition.D. Suicidal ideations are not typical of serotonin syndrome; they may be more related to underlying mood disorders or medication effects.
