NURS 6630 Week 3: Self Assessment Quiz with 100% correct answers
Question 1
G-protein coupled receptors are targets for several psychiatric medications. Given what we know about these receptors, what is the ultimate result we will see when one of them is activated in a way that would potentiate an action?
A. Intracellular activation of second messengers
B. Protein phosphorylation
Correct!
C. Modification of gene expression

A and B are both steps in the activities seen leading up to modification of gene expression.
Question 2
Upon blocking a Serotonin reuptake pump, what happens in the synaptic cleft and on the post synaptic cell membrane?
A. The result will be an increase in available Serotonin in the synaptic cleft causing the post synaptic cell to increase the number of Serotonin receptors.
Correct!
B. The result will be an increase in the available Serotonin in the synaptic cleft causing the post synaptic neuron to reduce the number of Serotonin receptors.
C. The result will be an increase in Serotonin in the synaptic cleft resulting in an increase in reuptake pumps on the presynaptic neuron.
D. The result will be an increase in Serotonin in the synaptic cleft resulting in a decrease in reuptake pumps on the pre-synaptic neuron. NURS 6630 Week 3: Self Assessment Quiz with 100% correct answers
A, C, and D are misrepresentations of what occurs when you increase Serotonin in the synaptic cleft. There is no effect on the pre-synaptic neuron, and the increases in Serotonin result in a reduction of receptor concentration on the post-synaptic neuron.
Question 3
Motivation is a component of patient-focused interventions to enhance adherence. Based on the transtheoretical model, readiness to change can fluctuate across five stages. Which stage is represented by the patient who is aware that a problem exists and, while seriously thinking about overcoming it, has not yet committed to a plan of action?
Preparation
Action
Correct!
Contemplation
Maintenance
Question 4
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
Correct!
C. Rapid effector pathways
D. NMDA glutamate receptor pathways
Answer B is fictitious, D is a type of rapid effector pathway, and A represents G-protein coupled receptors.
Question 5
Of the components of patient-focused interventions to enhance adherence, which component includes the following strategies: adaptive thinking, use of cues, and support?
Motivation
Correct!
Skills
Logistics
Education
Skills include adaptive thinking, problem solving, use of cues, and support.
Question 6
Treatment adherence is affected by several different factors. Clinical factors include mood, anxiety, psychosis, and substance misuse. There are also patient factors such as knowledge, attitude, and beliefs; economic and racial/ethnic disparities, and clinical encounters. A patient who presents hopeless, with decreased energy, and poor concentration is affected by which factor?
Substance misuse
Knowledge deficits
Attitude ad belief system
Correct!
Mood
These are signs of an altered mood.
Question 7
Neurotransmitters are defined by four essential characteristics. These are:
A. Neurotransmitters are synthesized within presynaptic neurons. NURS 6630 Week 3: Self Assessment Quiz with 100% correct answers
B. Depolarization of a neuron results in the release of a neurotransmitter, which exerts a multitude of actions on the postsynaptic neuron.
C. Their action on postsynaptic neurons can be replicated by administering a drug that mimics the activity of the endogenous neurotransmitter.
D. Their action in the synaptic cleft is terminated by a specific action.
Correct!
E. A, C, and D only
Answer B should read a “discrete” (not multitude) action on the post synaptic neuron.
Question 8
Neurotransmission is unidirectional insofar as chemical and electrical conduction is concerned within the individual neuron. Of the following descriptions, which 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 synaptic cleft (signal conduction through a neuron)?
Cell body, dendrites, Axon, Axon terminals
Dendrites, Axon, Cell body, Axon, Axon terminals
Correct!
Dendrites, Cell body, Axon, Axon terminals
Axon terminals, Axon, Cell body, Dendrites
All of the other options are mis-sequenced in signal conduction.
Question 9
The synaptic cleft is best characterized by which of the following statements?
A. The synaptic cleft is the space between a single neuron’s dendrites and axon terminals in which intracellular communication occurs through the release of neurotransmitters allowing for signal conduction throughout the central nervous system.
B. The synaptic cleft is the space between the cell body and axon terminals that allows for release of neurotransmitters from the presynaptic neuron for intercellular communication with an adjacent neuron (post synaptic neuron).
Correct!
C. The synaptic cleft is an area where dendrites and axon terminals are within close proximity, allowing for the release of a neurotransmitter from a presynaptic neuron that can interact with receptors on dendritic cells of a post synaptic neuron, which is the main basis for intercellular communication of neurons.
Answer A represents a neuron communicating with itself and
