A nurse on a medical unit overhears a discussion about the failure of psychobiologic interventions for clients with mental disorders. Which statement could be made to counteract that supposition?
1. "There is a current moratorium on development of new drugs to correct biochemical imbalances in the brain."
2. "Contemporary research findings indicate that the field of psychobiology and effective interventions is growing rapidly."
3. "There are subjective reports that exposure to bright light and white noise provides effective treatment for mental disorders."
4. "Restriction of nutrients and non-nutrients is no longer believed to affect behavior."
2
Rationale: There are major breakthroughs in psychobiologic knowledge of the brain, the mind, the spirit, and behavior. Research has generated new understanding of how genetics, immunology, biorhythms, brain structure, and brain biochemistry influence mental disorders. New drugs are being tested and prescribed and psychobiologic interventions such as exposure to bright light and white noise have been shown to affect behavior. Psychobiologic interventions have become commonplace.
