A nurse is teaching a group of students about how CNS drugs are developed. Which statement by a student indicates a need for further teaching?
a. "Central nervous system drug development relies on observations of their effects on human behavior."
b. "Studies of new central nervous system drugs in healthy subjects can produce paradoxical effects."
c. "Our knowledge of the neurochemical and physiologic changes that underlie mental illness is incomplete."
d. "These drugs are developed based on scientific knowledge of CNS transmitters and receptors."
ANS: D
The deficiencies in knowledge about how CNS transmitters and receptors work make systematic development of CNS drugs difficult. Testing in healthy subjects often leads either to no effect or to paradoxical effects. Medical knowledge of the neurochemical and physiologic changes underlying mental illness is incomplete. The development of CNS drugs depends less on knowledge of how the CNS functions and how these drugs effect that process and more on how administering one of these agents leads to changes in behavior.
