WALDEN NURS 6630| NURS 6630: PHYCHOPHARMACOLOGY LATEST FINAL EXAM QUESTIONS AND VERIFIED CORRECT ANSWERS Serotonin (5HT) is a neurotransmitter associated with mood, sleep, and psychosis. There are several serotonin receptors all over the human body. A unique aspect of the second-generation antipsychotics is their ability to block 5HT2a receptors. What is the effect of this inhibition?A. Stabilizes dopamine concentrations in the CNS B. Induces anxiety C. Causes hallucination D. Reduces platelet function A is the correct answer B. Represents antagonism of 5HT1a. C. Represents a 5HT2a agonist D Represents what happens when you inhibit SERT Receptors trigger one of two effector pathways resulting in changes in neuronal activity. These changes will, ultimately, effect gene expression. Which effector pathway is characterized by ion flux through transmitter-activated channels resulting in an altered membrane potential and neuronal activity?,A. Slow effector pathways B. Modulated effector pathways C. Rapid effector pathways D. NMDA glutamate receptor pathways A. Represents G-coupled receptors B. is fictitious C. Is the correct answer D. is a type of rapid effector pathway Which of the following consists of all the known major neurotransmitters that are relevant in psychiatry?A. glutamate, GABA, dopamine, serotonin, norepi, histamine, steroids, nitric oxide B. Glutamate, GABA, dopa, NE, serotonin, ACTLCH, histamine, endogenous opioids, steroids, cannabinoids, nitric pxide C. glutamate, GABA, dopamine, serotonin, acetylcholine, endogenous opioids, nitric oxide, cannabinoids, steroids D. glutamate, GABA, dopamine, serotonin, norepinephrine, endogenous opioids, steroids, histamine, nitric oxide B is correct If a patient admits to taking his meds every other day (instead of daily, as Rx) a potential concern would be:A. Sufficient understanding or acceptance of the illness B. Abuse C. Expense D. is the desired effect recognized at a lower daily dose? A. represents a patient taking his medication sporadically B. represents taking too much C. is the correct answer D. represents a patient taking a lower than prescribed dose daily Introducing adherence in facilitating treatment goals is something that would be necessary in a patient who has previously displayed nonadherence patterns.False It is introduced as early as possible in treatment to mitagate the risks associated with non adhernece Glia cells play a supportive role to the neuron. A few of the functions of the glial cells include providing nutrition, maintaining homeostasis, stabilizing synapses, and myelinating axons. The glial cells are categorized as microglia and macroglia. Of these two cell types, which one plays an active and critical role in glutamatergic neurotransmission by providing a co-agonist required for glutamate receptor function?A Microglial B. Macroglial B is correct A. Microglial cells are small, phagocytic cells related to peripheral macrophages The human brain is subcategorized into four major structures. These structures include the cerebral cortex, brainstem, subcortical structures, and the cerebellum. Of these major categories, which one houses the area of the brain that has been found in some neuropathological studies of patients with schizophrenia to be of smaller size?A. Cerebral Cortex B.Brainstem C. Subcortical Structures D. Cerebellum the correct answer is C Which neurotransmitter is considered the major excitatory neurotransmitter?A. Glycine B. GABA C. Glutamate D. Serotonin A & B are inhibitor and D is involved in mood and sleep The correct answer is C Neurotransmission is unidirectional insofar as chemical and electrical conduction is concerned within the individual neuron. Which of the following descriptions best characterizes the order of neurotransmitter/receptor interaction that results in an electrical signal impulse and the release of another neurotransmitter for interaction in the
