NURS 6630 Short Answer Assessment
A Sample Answer For the Assignment: NURS 6630 Short Answer Assessment
Appropriate Drug Therapy for a Patient with MDD and a History of Alcohol Abuse
A combination of an antidepressant and a medicine that treats alcohol abuse would probably be the best pharmacological therapy for a patient with MDD and a history of alcohol consumption. As a first-line therapy for MDD, selective serotonin reuptake inhibitors like fluoxetine or sertraline are advised.
Naltrexone may also be administered to ease alcohol withdrawal symptoms and cravings. In this patient, antidepressants such as monoamine oxidase inhibitors are not advised since they raise the risk of seizures. Within six to eight weeks of beginning treatment, the patient should see a reduction in symptoms, but it’s crucial to keep up the medication for at least six to twelve months to avoid relapse (Akbar et al., 2018).

Week 2
Week 1: Introduction to Neuroanatomy
The human brain is organized into the cerebral cortex, brainstem, subcortical structures, and the cerebellum. These anatomical structures are made of inter-connected elements that create distributed and highly inter-connected circuits. It is in these circuits where cognition, behavior, and affect are processed.
—Camprodon, J. A., & Roffman, J. L. (2016, p. 6)
By using a combination of psychotherapy and medication therapy, psychiatric nurse practitioners (PNP) are positioned to provide a very unique type of care to patients with psychiatric disorders. To be successful in this role, you must have a strong theoretical foundation in pathophysiology, psychopharmacology, and neuroscience. This foundation will help you assess, diagnose, and treat patients as you relate presenting symptoms to theoretical neuronal functioning.
NURS 6630 Short Answer Assessment
This week, as you begin to study psychopharmacology, you will explore the basic functional unit of the nervous system, the neuron. You will review the structure of the neuron and you will examine the anatomy of the central nervous system and consider the functionality of the different structure and outward (phenotypic) expression of their activities. You will analyze these concepts as you complete your short answer assessment for this week.

PMHNP Study Support Lounge
Neurons are information messengers with three main parts namely the cell body, axon, and the dendrites (Kringelbach et al., 2020). The cell body is made up of a nucleus and cytoplasm and produces protein required to construct other parts of the neuron. The axon, on the other hand, extends from the cell body and carries signals away from the cell body while the dendrites carry signals toward the cell body and have numerous synapses to receive the signal from nearby neurons.
Upon stimulation, neurons transmit an electrical impulse that passes through the dendrite, to the cell body, axon, axon terminal, and finally, the stimulus is passed (Kringelbach et al., 2020). At the axonal terminal, the axon releases neurotransmitters that depolarize neighboring cells through synapses and by binding to the membrane of the dendrite.
Subcortical Structures
Other structures within the brain are subcortical structures that act as information hubs for the nervous system. Their main role is to relay and modulate information circulating in different areas of the brain. They include the basal ganglia, limbic structures, pituitary gland, and the diencephalon (Malinowski, 2019).
The limbic systems play a great role in learning and memory addiction. The systems provide the anatomical substrate for emotions and motivated behaviors, including the circulatory for reward-related events and stress responses. Specifically, the hippocampus is used to mediate a cognitive/spatial form of memory.
It controls learning and declarative memory which covers the memory of facts and events (Malinowski, 2019). The dorsal striatum also helps in memory by mediating the stimulus-response habit memory. Addiction on the other hand is linked to the limbic system through the orbitofrontal cortex and anterior cingulate gyrus (Malinowski, 2019).
In line with motor control, the nigra striatal region offers two anatomically and functionally distinct portions knowns as the substantia nigra pars compacta and the substantia nigra pars reticulata.
Glial Cells
Other essential components in the central nervous system are the glial cells. They include the astrocytes whose role is to maintain the environment for neuronal signaling by controlling the level of neurotransmitters surrounding the synapses (Hirbec et al., 2020). Equally, oligodendrocytes wrap around the axons forming a protective layer called myelin sheath which enhances neuron signaling.
The cells also include microglia, ependymal cells, and radial glial whose roles are clearing dead cells or removing harmful toxins, maintaining homeostasis, and regenerating neurons and other glial cells like astrocytes and oligodendrocytes respectively.
Neuron Communication
Neurons communicate with each other through synaptic transmission. A chemical synapse is registered at the axon terminal of the presynaptic neuron and the dendrite of the postsynaptic neuron (Malinowski, 2019). The dendrite picks up signals and passes the signals down to the axon, into the axon terminals, and into the synapses. The role of the chemical synapse is to transform the electrical signal in the presynaptic cell’s axon into a chemical signal and back into an electrical signal in the postsynaptic cell.
Neuroplasticity
Brain plasticity denotes the ability of the brain to reorganize itself and form new neural connections in response to extrinsic or intrinsic stimuli. Through axonal sprouting, the undamaged axons develop new nerve endings and reconnect neurons with severed or injured links (Mateos-Aparicio & Rodríguez-Moreno, 2019).
For instance, undamaged brain sites of stroke patients rewire themselves to take over functions of the damaged brain sites. Similarly, the undamaged axons sprout nerve endings that connect with other undamaged nerve cells to form new neural pathways (Mateos-Aparicio & Rodríguez-Moreno, 2019). For example, exposing the brain to specific grammatical rules helps it process and develop language.

Short Answer Assessment
In 4 or 5 sentences, describe the anatomy of the basic unit of the nervous system, the neuron. Include each part of the neuron and a general overview of electrical impulse conduction, the pathway it travels, and the net result at the termination of the impulse. Be specific and provide examples.
According to Javaid et al. (2020), the human brain comprises over 100 billion distinct neurons. The neuron’s cell body harbors the nucleus and serves as the point of attachment for both the dendrites and axons of the neuron. The term “soma” is sometimes used to refer to the cell body, while axon clusters, commonly referred to as nerves in some contexts, can be found throughout the body in various locations. Neurons can interact with one another even when they are separated by large distances, which is made possible by the fact that they contain dendrites and axons. Furthermore, owing to the mechanism of electrical conduction intrinsic to neurons, nerve impulses can propagate at a remarkable pace, marked by a transient electrical oscillation that traverses from the neuronal soma, through its dendrites, and culminates at the terminal end of the axon.
Answer the following (listing is acceptable for these questions):What are the major components that make up subcortical structures?Basal ganglia: Pertains to a cluster of subcortical nuclei that are primarily accountable for regulating motor control (Wilfrid Jänig, 2022). Additionally, they play a crucial role in executive functions, motor learning, and emotional and behavioral regulation.Limbic structure: The limbic system is responsible for the regulation of motivation, mood, learning, and memory through its intricate network of structures and interconnected regions(Wilfrid Jänig, 2022). The interface between the subcortical structures and the cerebral cortex is located within the limbic system. The limbic system exerts its influence on the autonomic nervous system and the endocrine systemThalamic structures: The structure in question comprises four distinct components, namely the thalamus, epithalamus, subthalamus, and hypothalamus. Each of the aforementioned structures plays a crucial role in the survival and optimal operation of the human body (Wilfrid Jänig, 2022). Therefore, it is imperative to familiarize oneself with their anatomy. Cerebellar: The cerebellum is a neuroanatomical structure situated in the posterior cranial fossa, superior and posterior to the pontomedullary junction, where the spinal cord merges with the brainstem. The aforementioned structure is a significant subcortical entity that has an impact not only on motor function but also potentially on cognitive and emotional processes (Wilfrid Jänig, 2022).
Which component plays a role in learning, memory, and addiction?
According to Wilfrid Janig (2022), the limbic structure contributes to the capacity of the human body to acquire new information and retain it. Furthermore, it assumes a crucial function in the control of cognitive attention and behaviors that are addictive.
