  1. Which of the following is the correct definition of serotonin syndrome?

    1. Signs and symptoms caused by excessive stimulation of the serotonergic system.

    2. Signs and symptoms caused by an overdose of serotonergic drugs.

    3. A clinical condition that closely resembles neuroleptic malignant syndrome.

    4. A clinical condition characterized hyperthermia, clonus, and agitation.

  1. The basic cause of serotonin syndrome is:

    1. Prolonged use of drugs that affect the serotonergic system.

    2. Therapeutic use, overdose, or drug interaction involving serotonergic medications.
