1. Explain the agonist-to-antagonist spectrum of action of psychopharmacologic agents.
2. Compare and contrast the actions of g couple proteins and ion gated channels.
3. Explain the role of epigenetics in pharmacologic action.
4. Explain how this information may impact the way you prescribe medications to clients. Include a specific example of a situation or case with a client in which the psychiatric mental health nurse practitioner must be aware of the medication’s action.

Introduction to Neuroscience Sample
Psychiatric mental health nurse practitioners play a fundamental role in the management of psychiatric disorders. Undeniably, their knowledge regarding the pathophysiology of multifarious mental disorders need to be top notch. However, in addition to the pathophysiological knowhow, PMNHPs need to understand the various mechanisms of action of relevant medications and the manner in which they influence the central nervous system to stabilize the neurochemicals responsible for the existence of these conditions. Thus, PMNHPs require to have knowledge concerning the impact of psychopharmacological medications from their agnostic-to-antagonist spectrum of action. In addition, knowing about the roles of g-coupled proteins and ion gated channels in the entire process of managing mental health conditions becomes an important tool for these nurses. Further, other factors such as epigenetics also influence the pharmacologic action of drugs. As such, a collation of the above information may be fundamental in the prescription of medications to clients; hence, their analysis becomes important.
Agonist-To-Antagonist Spectrum of Action of Psychopharmacologic Agents
The prescription of psychopharmacological agents occurs based on the mechanisms of action of each molecule. Fundamentally, pharmacological actions of antipsychotics such as agonism and antagonism principally influences neurotransmitters or receptors. According to scholarship on the matter, agonists are referred to as the kinds of drugs or receptor ligands that bind to certain receptors in order to produce the desired therapeutic effect (). Specifically, agonists bind to receptors and modulate the activation of the receptors in order to produce the requisite action. The modulation occurs when the agonists alter the conformation of the receptor in order to optimally open the ion channel as well as induce the maximum frequency of the receptors for binding purposes. As a consequence, a maximum downstream signal transduction that has the capacity to be mediated by a receptor occurs.
