Thyroxine
Erythropoietin
Glutamate
Serotonin
The Correct Answer is C
A) Incorrect. Thyroxine is a hormone produced by the thyroid gland and is not directly implicated in the etiology of schizophrenia.
B) Incorrect. Erythropoietin is a hormone that stimulates the production of red blood cells and is not directly implicated in the etiology of schizophrenia.
C) Correct. Glutamate, an excitatory neurotransmitter, has been implicated in the development of schizophrenia. Abnormalities in glutamate signaling have been identified in individuals with schizophrenia.

Correct Answer is A
Explanation
A. Increase your fluid and fiber intake to prevent constipation – Risperidone, an atypical antipsychotic, can cause constipation due to its anticholinergic effects. Increasing fluid and fiber intake can help prevent this.
B. Have your blood pressure checked frequently for hypertension – Risperidone is more commonly associated with orthostatic hypotension, not hypertension.
C. Expect to have your blood checked weekly for serum electrolyte imbalances – Unlike clozapine, risperidone does not require frequent blood monitoring for electrolyte imbalances.
D. Increase caloric intake to prevent weight loss – Risperidone is more likely to cause weight gain rather than weight loss, so increasing caloric intake is unnecessary.
