This guide will demonstrate how to complete the Walden University  NURS 6501 Knowledge Check: Psychological Disorders assignment based on general principles of academic writing. Here, we will show you the A, B, Cs of completing an academic paper, irrespective of the instructions. After guiding you through what to do, the guide will leave one or two sample essays at the end to highlight the various sections discussed below.

 

How to Research and Prepare for NURS 6501 Knowledge Check: Psychological Disorders

 

Whether one passes or fails an academic assignment such as the Walden University  NURS 6501 Knowledge Check: Psychological Disorders depends on the preparation done beforehand. The first thing to do once you receive an assignment is to quickly skim through the requirements. Once that is done, start going through the instructions one by one to clearly understand what the instructor wants. The most important thing here is to understand the required format—whether it is APA, MLA, Chicago, etc.

 

After understanding the requirements of the paper, the next phase is to gather relevant materials. The first place to start the research process is the weekly resources. Go through the resources provided in the instructions to determine which ones fit the assignment. After reviewing the provided resources, use the university library to search for additional resources. After gathering sufficient and necessary resources, you are now ready to start drafting your paper.

 

How to Write the Introduction for  NURS 6501 Knowledge Check: Psychological Disorders 

 

The introduction for the Walden University  NURS 6501 Knowledge Check: Psychological Disorders is where you tell the instructor what your paper will encompass. In three to four statements, highlight the important points that will form the basis of your paper. Here, you can include statistics to show the importance of the topic you will be discussing. At the end of the introduction, write a clear purpose statement outlining what exactly will be contained in the paper. This statement will start with “The purpose of this paper…” and then proceed to outline the various sections of the instructions.

 

How to Write the Body for  NURS 6501 Knowledge Check: Psychological Disorders 

 

After the introduction, move into the main part of the  NURS 6501 Knowledge Check: Psychological Disorders assignment, which is the body. Given that the paper you will be writing is not experimental, the way you organize the headings and subheadings of your paper is critically important. In some cases, you might have to use more subheadings to properly organize the assignment. The organization will depend on the rubric provided. Carefully examine the rubric, as it will contain all the detailed requirements of the assignment. Sometimes, the rubric will have information that the normal instructions lack.

 

Another important factor to consider at this point is how to do citations. In-text citations are fundamental as they support the arguments and points you make in the paper. At this point, the resources gathered at the beginning will come in handy. Integrating the ideas of the authors with your own will ensure that you produce a comprehensive paper. Also, follow the given citation format. In most cases, APA 7 is the preferred format for nursing assignments.

 

How to Write the Conclusion for  NURS 6501 Knowledge Check: Psychological Disorders 

 

After completing the main sections, write the conclusion of your paper. The conclusion is a summary of the main points you made in your paper. However, you need to rewrite the points and not simply copy and paste them. By restating the points from each subheading, you will provide a nuanced overview of the assignment to the reader.

 

How to Format the References List for  NURS 6501 Knowledge Check: Psychological Disorders

 

The very last part of your paper involves listing the sources used in your paper. These sources should be listed in alphabetical order and double-spaced. Additionally, use a hanging indent for each source that appears in this list. Lastly, only the sources cited within the body of the paper should appear here.

Sample Answer for NURS 6501 Knowledge Check: Psychological Disorders

Question 5

Scenario 2: Bipolar Disorder

A 44-year-old female  came to the clinic today brought in by her husband. He notes that she has been with various states of depression and irritability over the past 3 months with extreme fatigue, has lost 20 pounds and has insomnia. He has come home from work to find his wife sitting in front of the TV and not moving for hours. In the past few days, she suddenly has become very hyperactive, has been talking incessantly, has been easily distracted and seems to “flit from one thing to another.”. She hasn’t slept in 3 days. The wife went on an excessive shopping spree for new clothes that resulted in their credit card being denied for exceeding the line of credit. The wife is unable to sit in the exam room and is currently pacing the hallway muttering to herself and is reluctant to talk with or be examined the ARNP. Physical observation shows agitated movements, rapid fire speech, and hyperactivity.

DIAGNOSIS: bipolar type 2 disorder.

Question

  1. How does genetics play in the development of bipolar 2 disorders?  

 

Your Answer:

Genetics plays a significant role in the development of bipolar 2 disorder. Having a family history of the condition increases the risk. Bipolar disorders have a heritable component, and certain genetic markers may be associated with an increased risk. However, bipolar 2 disorder is a complex condition influenced by a combination of genetic and environmental factors. Early identification of genetic risk may aid in early intervention and personalized treatment approaches. Research on the exact genetic contributions to bipolar 2 disorder is ongoing.

Scenario 1: Schizophrenia

A 22-year-old female student was brought to her college student health department by her boyfriend. He was concerned about the changes in her behavior. The boyfriend noted that she has been hearing voices, and seeing things that are not there. She also thinks that there are people that want to harm her. She told her family that she cannot finish college as the voices told her to quit because she is “dumb”.  The boyfriend relates episodes of unexpected rage and crying.

PMH:  noncontributory

FH: positive for a first cousin who “had mental problems”.

Question:

1.     Genetics are sometimes attached to schizophrenia explain this.

Selected Answer:

Genetic can be linked to the disorder, it can run in the families. if one parent has schizophrenia, the children have a 10% chance of developing the disorder. it is now clear that it combined the effect of many genes, each playing an important role. It has a variable susceptible genes interacting with the environmental factors. The  genetic factors have  strong evidence for 9 linkages sites : 1q,5q,6p,6q,8p,10p,13q,15q and 22q.
Correct Answer:
The causes of schizophrenia are not known. There are probably at least 2 sets of risk factors, genetic and perinatal. In addition, undefined socioenvironmental factors may increase the risk of schizophrenia in international migrants or urban populations of ethnic minorities. Increased paternal age is associated with a greater risk of schizophrenia. The risk of schizophrenia is elevated in biologic relatives of persons with schizophrenia but not in adopted relatives. The risk of schizophrenia in first-degree relatives of persons with schizophrenia is 10%. If both parents have schizophrenia, the risk of schizophrenia in their child is 40%. Concordance for schizophrenia is about 10% for dizygotic twins and 40-50% for monozygotic twins. Genome-wide association studies have identified many candidate genes, but the individual gene variants that have been implicated so far account for only a small fraction of schizophrenia cases, and these findings have not always been replicated in different studies. The genes that have been found mostly change a gene’s expression or a protein’s function in a small way.

Question:

What roles do neurotransmitters play in the development of schizophrenia?

 

Selected Answer:

occurs due to a chemical imbalance in the brain. The neurotransmitters are the carriers of brain activity The neurotransmitters like dopamine, glutamine, GABA, serotonin, norepinephrine, and oxytocin are responsible for schizophrenia but dopamine has a major role to play.

Correct Answer:

Abnormalities of the dopaminergic system are thought to exist in schizophrenia. The first observable effective antipsychotic drugs, chlorpromazine and reserpine, were structurally different from each other, but they shared antidopaminergic properties. Drugs that diminish the firing rates of mesolimbic dopamine D2 neurons are antipsychotic, and drugs that stimulate these neurons (eg, amphetamines) exacerbate psychotic symptoms. Hypodopaminergic activity in the mesocortical system, leading to negative symptoms, and hyperdopaminergic activity in the mesolimbic system, leading to positive symptoms, may coexist. The newer antipsychotic drugs block both dopamine D2 and serotonin (5- hydroxytryptamine [5-HT]) receptors. Clozapine, probably the most effective antipsychotic agent, is a particularly weak dopamine D2 antagonist. Thus, other neurotransmitter systems, such as norepinephrine, serotonin, and gamma-aminobutyric acid (GABA), are undoubtedly involved.

DIAGOSIS: schizophrenia.

Questions:

Explain what structural abnormalities are seen in people with schizophrenia.

 

Selected Answer:

The structural abnormalities will be seen on PATHOLOGY on functional magnetic resonance imaging studies will show consistent dysmorphological findings in schizophrenia are the lateral ventricle enlargement, which is indicative of reduced brain volume, and third ventricular enlargement which suggest a reduction in cortical gray and white matter and in certain areas such as the frontal lobes, and temporal lobe volume and reduction of overall brain volume.

Correct Answer:

Advances in neuroimaging studies show differences between the brains of those with schizophrenia and those without this disorder. In people with schizophrenia, the ventricles are somewhat larger, there is decreased brain volume in medial temporal areas, and changes are seen in the hippocampus. Magnetic resonance imaging (MRI) studies show anatomic abnormalities in a network of neocortical and limbic regions and interconnecting white-matter tracts. Some studies using diffusion tensor imaging (DTI) to examine white matter found that 2 networks of white-matter tracts are reduced in schizophrenia. Brain imaging showed reductions in whole-brain volume and in left and right prefrontal and temporal lobe volumes in many people who are at high genetic risk for schizophrenia. The changes in prefrontal lobes are associated with increasing severity of psychotic symptoms. MRI studies of schizophrenic patients show that structural brain abnormalities may progress over time. The abnormalities identified included loss of whole-brain volume in both gray and white matter and increases in lateral ventricular volume.

Question

1.     How does genetics play in the development of bipolar 2 disorders?

 

Selected Answer:

Bipolar disorder is a mental health disorder, The mood can swing between negative and positive moods, which can occur quickly. The cause is unknown. Most of the time genetics have a major role major role  disorder, like a family with hx of the disorder,but other predisposing factors trigger could the disorder, changes of the  brain structure like  traumatic brain injuiiry and concussion, environmental factors like stressful events that could be related to work or personal life, seasonal factors like change of weather from winter to spring,

Correct Answer:

The pathophysiology of bipolar disorder, or manic-depressive illness (MDI), has not been fully identified, and there are no objective biologic markers that correspond definitively with the disease state. Twin, family, and adoption studies all indicate that bipolar disorder has a significant genetic component. Firstdegree relatives of a person with bipolar disorder are approximately 7 times more likely to develop bipolar disorder than the rest of the population, and the heritability of bipolar I disorder (BPI) has recently been estimated at 0.73. Bipolar individuals, who may exhibit psychotic behavior, have deficits in reelin expression linked to genetic loci located on the chromosome 22, which confers susceptibility to schizophrenia. Given that, there still are large variations in clinical symptoms suggests that developmental and environmental factors are as important as genetic factors in contributing to the etiology of mood disorders.

DIAGOSIS: schizophrenia.

Questions:

Explain what structural abnormalities are seen in people with schizophrenia.

 

Your Answer:

Schizophrenia is associated with structural abnormalities of the brain. One of the observed abnormalities in the brain is the differences in intracranial volumes of the different brain parts. Some patients with schizophrenia have been found to have reduced third ventricle volumes as compared to their normal, healthy counterparts. The third ventricle volumes are also higher in schizophrenia patients as compared to the healthy people. The cerebral volumes in these patients have also been identified to be reduced. The reduction in cerebral volume affects behavior in schizophrenia patients. Patients with schizophrenia also have reductions in frontal lobe volumes. The reduction affects higher order functions such as decision-making, speech, and critical thinking(Madre et al., 2020). Similarly, studies have demonstrated the reduction in the gray matter volume in these patients and increase in the volumes of the lateral ventricles and caudate nuclei.

Patients diagnosed with schizophrenia have also been found to have reduced volume of the gray matter. The reduction has been shown to be highly elevated before the development of the symptoms of schizophrenia. Imaging studies have also revealed that the gray matter in brain regions that include left orbital frontal cortex, occipital lobe, right temporal gyrus, lateral superior parietal lobe, and medial superior frontal gyrus. The additional structural changes that are evident in patients diagnosed with schizophrenia include increased amplitude of low-frequency fluctuations, cortical tissue loss, and lateral ventricular enlargement. Patients also have regional structural abnormalities when compared to their healthy counterparts. The regional abnormalities include small thalamus, small temporal lobes, enlarged caudate nucleus, and reversed cerebral asymmetries(Madre et al., 2020). Cumulatively, these structural abnormalities have been hypothesized to contribute to the development of symptoms of schizophrenia.

Sample Answer 3 for NURS 6501 Knowledge Check: Psychological Disorders

Scenario 1: Schizophrenia

  1. What are the known characteristics of schizophrenia and relate those to this patient?

Schizophrenia is a chronic mental disorder displayed in patients who interpreted reality abnormally just like the 22-year-old patient in the provided case study. It can lead to a combination of delusion. Hallucination and extremely disordered behaviour and thinking impair the patient normal functioning (Correll et al., 2019). The patient in the provided case study reported signs of auditory and visual hallucination, unexpected rage and crying, and delusion. Additional symptoms include disorganized speech and thinking as demonstrated by the results of the mental status examination. The patient also displayed negative symptoms such as inability to make eye contact and being socially withdrawn which are significant indications of schizophrenia disorder.

  1. Genetics are sometimes attached to schizophrenia explains this.

Pre-molecular and molecular genetic studies have reported that genetics play a significant role in the development of schizophrenia.  Consequently, the inheritance pattern of the disease demonstrates increased risk among first relatives. At the molecular level, several positional and functional genes associated with the development of schizophrenia have been identified, such as neuregulin (NRG-1, 8p12–21), proline dehydrogenase (PRODH-2, 22q11.21), dysbindin, (DTNBP1,6p22.3), catechol-O-methyltransferase (COMT, 22q11.21), G72 (13q34) / D-amino acid oxidase (DAAO,12q24),5HT2A and dopamine D3 receptor (DRD3) and regulator of G protein signaling (RGS-4) (Cleynen et al., 2021). Recent studies support schizophrenia candidate regions on chromosomes 1q, 2q, 5q, 6p, 8p, 10p, 13q,15q and 22q. Additional studies are however required to provide a precise association with the above-mentioned genetic factors concerning how they lead to the development of schizophrenia.

  1. What roles do neurotransmitters play in the development of schizophrenia?

Neurotransmitters are chemicals responsible for conveying messages between brain cells. Studies illustrate an association between changes in the levels of neurotransmitters in the brain to the development of schizophrenia. This is evident by the mechanism of antipsychotics in relieving symptoms of schizophrenia through altering the levels of certain neurotransmitters in the brain. Recent studies have reported several biochemical alterations in schizophrenia, concerningneurotransmitter dysfunction in different systems, with the most prominent being γ‎-aminobutyric acid (GABA), serotonin, glutamate, and dopamine (Müller, 2018). For instance, alterations in the signaling of dopamine and hyperactivity of the D2 receptor in the limbic and subcortical region of the brain have been associated with some of the schizophrenia symptoms including delusion and hallucination. Consequently, hypodopaminergic activity in the mesocortical system is also associated with negative symptoms of schizophrenia such as flattening, lack of pleasure, withdrawal, and inability to follow through.

  1. Explain what structural abnormalities are seen in people with schizophrenia.

Through imaging studies, several complex patterns of structural abnormalities have been reported among patients diagnosed with schizophrenia, in addition to those who are at high risk of the disorder (Zhao et al., 2018). For example, MRI studies have reported a reduced volume of grey matter in the prefrontal, superior temporal, and medial temporal areas of the brain. These regions of the brain are involved in several functions such as short-term memory/decision making, processing of auditory information, and episodic memory respectively. Postmortem studies on the other hand report that a reduction in the cortical grey matter does not indicate loss of cell bodies but instead, reflects a reduction in synaptic density and dendritic complexity which may impair intraneuronal integration and communication leading to cognitive changes among other associated symptoms. Disruptions in the integrity of the white matter have also been implicated in schizophrenia, given that it forms the structural connections between different regions of the brain.

Scenario 2: Bipolar Disorder

  1. How does genetics play in the development of bipolar 2 disorders?  

Bipolar disorder (BD) is characterized by extreme shifts in the patient’s mood, behaviour, and energy levels. The patient in the provided case study is however diagnosed with bipolar 2 disorder, which is characterized by hypomanic and depressive episodes. The inheritance pattern of bipolar 2 disorder is quite unclear. Studies however report greater risks among first-degree relatives, with genetic factors accounting for approximately 80% of the causes of this mental disorder (Gordovez& McMahon, 2020). Genome-wide association studies (GWASs) have associated increased risk of bipolar 2 disorder with several genetic factors such as alpha-1 subunit of the L-type voltage-gated calcium channel (CACNA1C), teneurin transmembrane protein 4 (ODZ4), ankyrin G node of Ranvier (ANK3), nesprin-1 (SYNE1) and diacylglycerol kinase eta (DGKH).For instance, the DGKH is involved in diacylglycerol (DAG) phosphorylation in the phosphoinositol pathway sensitive to lithium, which contributes to the development of the bipolar disorder.
