Question 6
Motivation is a component of patient-focused interventions to enhance adherence. Based on the transtheoretical model, readiness to change can fluctuate across five stages.

Question 7
The human brain is subcategorized into four major structures. These structures include the cerebral cortex, brainstem, subcortical structures, and the cerebellum.

- Cerebral cortex
- Brainstem
- Subcortical structures
- Cerebellum
Question 8
Neurotransmitters are defined by four essential characteristics. These are:
Group of answer choices
A. Neurotransmitters are synthesized within presynaptic neurons.
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.
E. A, C, and D only
Question 9
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?
Group of answer choices
A. Stabilizes dopamine concentrations in the CNS
B. Induces anxiety
C. Causes hallucinations
D. Reduces platelet function
Question 10
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?
Group of answer choices
- Substance misuse
- Knowledge deficits
- Attitude and belief system
- Mood
Question 11
A patient arrives in the ED via EMS having a grand mal seizure. The ED physician instructs the RN to give 10 milligrams of Diazepam IV X1 dose STAT. The patient’s seizure breaks within 2 minutes of the Diazepam being administered. The mechanism by which this medication causes rapid resolution of seizure activity is via which receptor type (effector pathway/receptor subtype)?
Group of answer choices
A. Slow effector pathways/G-protein coupled receptor
B. Slow effector pathway/ion channel
C. Rapid effector pathways/G-protein coupled receptor
D. Rapid effector pathway/ion channel
Question 12
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)?
Group of answer choices
- Cell body, dendrites, Axon, Axon terminals
- Dendrites, Axon, Cell body, Axon, Axon terminals
- Dendrites, Cell body, Axon, Axon terminals
- Axon terminals, Axon, Cell body, Dendrites
Question 15
If a patient admits to taking his medication every other day (instead of daily, as prescribed), a potential concern would be:
Group of answer choices
A. Sufficient understanding or acceptance of the illness
B. Abuse of the medication
C. Expense
D. Is the desired effect recognized at a lower daily dose?
Question 16
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?
Group of answer choices
A. Slow effector pathways
B. Modulated effector pathways
C. Rapid effector pathways
D. NMDA glutamate receptor pathways
Question 17
Upon blocking a Serotonin reuptake pump, what happens in the synaptic cleft and on the post-synaptic cell membrane?
Group of answer choices
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.
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.
