Walden University NURS 6051 Knowledge Check: Cardiovascular And Respiratory Disorders– Step-By-Step Guide

 

This guide will demonstrate how to complete the Walden University  NURS 6051 Knowledge Check: Cardiovascular And Respiratory 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 6051 Knowledge Check: Cardiovascular And Respiratory Disorders  

 

Whether one passes or fails an academic assignment such as the Walden University  NURS 6051 Knowledge Check: Cardiovascular And Respiratory 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 6051 Knowledge Check: Cardiovascular And Respiratory Disorders   

 

The introduction for the Walden University  NURS 6051 Knowledge Check: Cardiovascular And Respiratory 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 6051 Knowledge Check: Cardiovascular And Respiratory Disorders   

 

After the introduction, move into the main part of the  NURS 6051 Knowledge Check: Cardiovascular And Respiratory 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 6051 Knowledge Check: Cardiovascular And Respiratory 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 6051 Knowledge Check: Cardiovascular And Respiratory 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 6051 Knowledge Check: Cardiovascular And Respiratory Disorders

Scenario 1: Myocardial Infarction

CC: “I woke up this morning at 6 a.m. with numbness in my left arm and pain in my chest. It feels tight right here (mid-sternal).” “My dad had a heart attack when he was 56-years-old and I am scared because I am 56-years-old.”

HPI: Patient is a 56-year-old Caucasian male who presents to Express Hospital  Emergency Department with a chief complaint of chest pain that radiates down his left arm. He states this started this morning and has been getting worse, pointing to the mid-sternal area, “it feels like an elephant is sitting on my chest and having a hard time breathing”. He rates the pain as 9/10. Nothing has made the pain better or worse. He denies any previous episode of chest pain. Denies nausea, or lightheadedness. Nitroglycerin 0.4 mg tablet sublingual x 1 which decreased pain to 7/10.

Lipid panel reveals Total Cholesterol 424 mg/dl, high density lipoprotein (HDL) 26 mg/dl, Low Density Lipoprotein (LDL) 166 mg/dl, Triglycerides 702 mg/dl, Very Low-Density Lipoprotein (VLDL) 64 mg/dl

His diagnosis is an acute inferior wall myocardial infarction.

Question:

Which cholesterol is considered the “good” cholesterol and what does it do?

High-density lipoprotein (HDL) is also called the “good” cholesterol, while low-density lipoprotein (LDL) is called “bad” cholesterol. HDL absorbs cholesterol in the blood and transports it back to the liver. The liver then flushes the cholesterol from the body. High levels of HDL cholesterol lower the risk of heart disease and stroke. HDL has a diverse protein and lipid composition, contributing to its atheroprotective function (Jomard & Osto, 2020). In the vessel wall, HDL undergoes transcytosis through endothelial cells into the sub-endothelial space, where it efflux cholesterol from foam cells, preventing plaque formation. In addition, HDLs have other beneficial properties, like nitric oxide production stimulation, anti-oxidant capacity, anti-inflammatory, and anti-apoptotic actions.

Scenario 1: Myocardial Infarction

CC: “I woke up this morning at 6 a.m. with numbness in my left arm and pain in my chest. It feels tight right here (mid-sternal).” “My dad had a heart attack when he was 56-years-old and I am scared because I am 56-years-old.”

He states this started this morning and has been getting worse, pointing to the mid-sternal area, “it feels like an elephant is sitting on my chest and having a hard time breathing”. He rates the pain as 9/10. Nothing has made the pain better or worse. He denies any previous episode of chest pain. Denies nausea, or lightheadedness. Nitroglycerin 0.4 mg tablet sublingual x 1 which decreased pain to 7/10.

His diagnosis is an acute inferior wall myocardial infarction.

Question:

  1. How does inflammation contribute to the development of atherosclerosis?

Atherosclerosis is a chronic inflammatory condition with an autoimmune component. It is accompanied by a chronic, low-grade inflammatory response that attracts cells of the innate and adaptive immune systems into the atherosclerotic plaque (Wolf & Ley, 2019). The autoimmune response is clinically best documented by antibodies against LDL and other atherosclerosis antigens. The continued development of atherosclerosis involves an inflammatory response, which begins with injury to the vascular endothelium. Inflammation has multiple effects on the arterial wall, including attracting inflammatory cells like macrophages (Jebari-Benslaiman et al., 2022). The macrophages infiltrate the injured vascular endothelium and ingest lipids, making them foam cells. Activated macrophages release biochemical substances that can further damage the endothelium, attracting platelets and initiating clotting.

 

Scenario 2: Pleural Friction Rub

A 35-year-old female with a positive history of systemic lupus erythematosus (SLE) presents to the Emergency Room (ER) with complaints of sharp retrosternal chest pain that worsens with deep breathing or lying down. She reports a 5-day history of low-grade fever, listlessness and says she feels like she had the flu. Physical exam reveals tachycardia and a pleural friction rub. She was diagnosed with acute pericarditis.

Question:

  1. Because of the result of a pleural friction rub, what does the APRN recognize?

Physical findings in a pleural friction rub include an adventitious breath sound on chest auscultation, which is heard as a harsh, grunting sound during systole and diastole. When examining the patient with a friction rub, the APRN will identify that SLE caused an inflammation of the pericardium resulting in pericarditis (Dein et al., 2019). When the patient was in active lupus, antigen-antibody complexes formed and mediated inflammation of the pericardium. Therefore, the APRN will recognize that the client’s symptoms are caused by pericarditis, which is characterized by fever, dyspnea, tachycardia, and faint heart sounds. Pericardial rub is a common finding on physical exam.

Scenario 4: Deep Venous Thrombosis (DVT)

A 81-year-old obese female patient who 48 hours post-op left total hip replacement. The patient has had severe nausea and vomiting and has been unable to go to physical therapy. Her mucus membranes are dry. The patient says the skin on her left leg is too tight. Exam reveals a swollen, tense, and red colored calf. The patient has a duplex ultrasound which reveals the presence of a deep venous thrombosis (DVT).

Question:

  1. Given the history of the patient explain what contributed to the development of a deep venous thrombosis (DVT)

The patient’s DVT was caused by venous stasis, activation of the coagulation pathway, and vein damage. The patient was at risk of developing a thrombus due to being obese. The patient likely developed Venous stasis following vein damage during the total hip replacement. Immobility of the left leg following surgery and failure to attend physical therapy caused venous stasis contributing to DVT (Chindamo & Marques, 2019). The venous stasis caused an increased viscosity resulting in the formation of microthrombi, which are not cleared by fluid movement when there is high blood viscosity. This resulted in the formation of a blood clot from the microthrombi, which interrupted blood flow in the vein.

Scenario 5:  COPD

A 66-year-old female with a 50 pack/year history of cigarette smoking had a CT scan and was diagnosed with emphysema.  He asks if this means he has chronic obstructive pulmonary disease (COPD).

Question:

  1. There is a clear relationship between emphysema and COPD, explain the pathophysiology of emphysema and the relationship to COPD.

Emphysema is characterized by two significant changes: loss of lung elasticity and hyperinflation of the lung. It occurs when protein-degrading enzymes called proteases are at higher-than-normal levels. They damage the alveoli and the small airways by breaking down elastin (Rodrigues et al., 2021). High protease levels make the alveolar sacs lose their elasticity, and the small airways collapse or narrow. Some alveoli get destroyed, and others become large and flaccid with reduced area for effective gas exchange. An increased amount of air is trapped in the lungs due to loss of elastic recoil in the alveolar walls, overstretching and enlargement of the alveoli into air-filled spaces, and collapse of small airways (Rodrigues et al., 2021). Emphysema is linked to COPD since oxygenation is affected by the loss of alveolar tissue and the increased work of breathing. Usually, inhalation begins before exhalation is completed, causing an uncoordinated breathing pattern.

Sample Answer 2 for NURS 6051 Knowledge Check: Cardiovascular And Respiratory Disorders

Question 1

2 out of 2 points

CC: “I have been having terrible chest and arm pain for the past 2 hours and I think I am having a heart attack.”

HPI: Mr. Hammond is a 57-year-old African American male who presents to the Emergency Department with a chief complaint of chest pain that radiates down his left arm. He states that he started having pain several hours ago and says the pain “it feels like an elephant is sitting on my chest”. He rates the pain as 8/10. Nothing has made the pain better or worse. He denies any previous episode of chest pain. Denies nausea, dyspnea, or lightheadedness. He was given 0.4 mg nitroglycerine tablet sublingual x 1 which decreased, but not stopped the pain.

Lipid panel reveals Total Cholesterol 324 mg/dl, high density lipoprotein (HDL) 31 mg/dl, Low Density Lipoprotein (LDL) 122 mg/dl, Triglycerides 402 mg/dl, Very Low-Density Lipoprotein (VLDL) 54 mg/dl

His diagnosis is an acute inferior wall myocardial infarction.

Musculoskeletal, metabolic, and multisystem health dysfunctions represent one of the most challenging health conditions that may have a complex challenge to the affected patient (Beefcroft & Hough, 2016). Symptoms of these conditions may range in severity. Musculoskeletal complications can affect the muscle, bone, tendons and joints. A major symptom that patients encounter is pain. Conditions may range from the ones that are sudden and short-lived to the ones that are lifelong and are associated with disability as well as ongoing pain. Among the notable changes that a patient with this condition may experience include persistent pain as well as mobility limitations. In this, the patients who may suffer from the long-term condition may experience severe pain that may be related to the wearing out of the tendons. For some patients with complex conditions, they may experience joint deformity that may be a long term condition, and it may be relatively challenging to treat it. When these abnormal changes occur, the involved patient may find it hard to handle some of the changes in weight, thus affecting some parts of the body (Black, 2016). Although musculoskeletal conditions may arise in many forms as well as a result of different factors, there are many ways that the situation may represent itself. The identification of specific symptoms of the disorder plays an essential role in the development of an approach to assist in the management of the stated condition.

1 of 2 Questions:

Why is HDL considered the “good” cholesterol?

Selected Answer: HDL carries between 20-25% of the total cholesterol in plasma. It is a good cholesterol since it accumulates the excess cholesterol that exists in body cells for excretion in the liver.
Correct Answer: HDL is considered the good cholesterol because it collects excess cholesterol in the body cells and transports it to the liver where it is excreted in the body cells and transports it to the liver where it is excreted in the body. HDL carries 20-25% of total plasma cholesterol.

  • Question 3

1 out of 1 points

A 45-year-old woman with a history of systemic lupus erythematosus (SLE) presents to the Emergency Room (ER) with complaints of sharp retrosternal chest pain that worsens with deep breathing or lying down. She reports a 3-day history of low-grade fever, listlessness and says she feels like she had the flu. Physical exam reveals tachycardia and a pleural friction rub. She was diagnosed with acute pericarditis.

 

Question:

 

What does the Advanced Practice Registered Nurse (APRN) recognize as the result of the pleural friction rub?

Selected Answer: The pericardium tends to roughen following inflammation caused by a post-viral syndrome or an underlying autoimmune disease. The roughening is what produces a classic rub that an APRN   can hear at the left sternal border and apex of the heart.
Correct Answer: The inflammation of the pericardium, due to either the underlying autoimmune disease or a post viral syndrome, causes roughening of the pericardium. The roughening of the pericardium causes the classic “rub” which can best be heard at the apex of the heart and left sternal border.

  • Question 4

1 out of 1 points

A 15-year-old adolescent male comes to the clinic with his parents with a chief complaint of fever, nausea, vomiting, poorly localized abdominal pain, arthralgias, and “swollen lymph nodes”. States he has felt “lousy” for a couple weeks. The fevers have been as high as 102 F. His parents thought he had the flu and took him to an Urgent Care Center. He was given Tamiflu® and sent home. He says the Tamiflu didn’t seem to work. States had a slight sore throat a couple weeks ago and attributed it to the flu. Physical exam revealed thin young man who appears to be uncomfortable but not acutely ill. Posterior pharynx reddened and tonsils 3+ without exudate. + anterior and posterior cervical lymphadenopathy. Tachycardic and a new onset 2/6 high-pitched, crescendo-decrescendo systolic ejection murmur auscultated at the left sternal border. Rapid strep +. The patient was diagnosed with acute rheumatic heart disease (RHD)

ALSO READ: Assignment 2: Digital Clinical Experience (DCE): Health History Assessment NURS 6512N-32

Question:

 

Explain how a positive strep test has caused the patient’s symptoms.

Selected Answer: A pharyngeal infection with GABHs (Group A Beta Hemolytic Streptococcus) often leads to the development of RHD, which is an abnormal response to cell-mediated responses. The inflammatory cascade associated with this process cause exudative and proliferative lesions, and scarring in the valve tissue. Since it is the endocardium which contains valves that is primarily affected, inflammation of the endocardium results to subsequent inflammation of valves.
Correct Answer: Rheumatic Heart Disease (RHD) only develops after a pharyngeal infection with Group A beta hemolytic streptococcus. It is an abnormal response to humoral and cell-mediated response to M proteins on the microorganisms. The intense inflammation caused by these reactions cause proliferative and exudative lesions in connective tissue. This inflammation causes scarring of the valve tissue. The inflammation usually affects the endocardium which contains the valves. Endocardial inflammation causes swelling of leaflets in the valves.

  • Question 5

1 out of 1 points

The APRN sees a 74-year-old obese female patient who is 2 days post-op after undergoing left total hip replacement. The patient has had severe post op nausea and vomiting and has been unable to go to physical therapy. Her mucus membranes are dry. The patient says she feels like the skin on her left leg is too tight. Exam reveals a swollen, tense, and red colored calf. The patient has a duplex ultrasound which reveals the presence of a deep venous thrombosis (DVT).

Question:

Describe the factors that could have contributed to the development of a DVT in this patient explain how each of the factors could cause DVT.

Selected Answer: When there is injury to a blood vessel, there is platelet adherence to blood vessel walls influenced by antiplatelet substances. When platelets aggregate, they form clots. Therefore, virchow’s triad damaged the blood vessel walls. Since this patient is reportedly obese, inability to engage in physical therapy and an advanced age caused venous stasis,
Correct Answer: Virchow’s Triad caused damage to the walls of the vessels. When there is injury to the intimal layer of the vessel, antiplatelet substances such as nitric oxide and prostacyclin, along with the expression of collagen on the vessel wall, causes adherence of the platelets to the vessel wall. The platelets become activated then aggregate forming clots. Venous stasis as a result of obesity, patient’s advanced age and inability to go to physical therapy.

  • Question 6

1 out of 1 points

A 45-year-old woman is 10 days status post partial small bowel resection for Crohn Disease and has been recuperating at home. She suddenly develops severe shortness of breath, becomes weak, and her blood pressure drops to 80/40 mmHg (previous readings ~130/80s mmHg). The pulse oximetry is 89% on room air. The APRN suspects the patient experienced a massive pulmonary embolus.

 

Question:

 

Explain why a large pulmonary embolus interferes with oxygenation.

Selected Answer: The pulmonary embolus lodged itself strategically in pulmonary circulation resulting to a mismatch in ventilation/perfusion (V/Q) reducing the area for the exchange of oxygen.
Correct Answer: The embolus lodges somewhere in the pulmonary circulation and causes a ventilation/perfusion mismatch (V/Q). Ventilation Perfusion mismatch or “V/Q defects” are defects in total lung ventilation perfusion ratio. It is a condition in which one or more areas of the lung receive oxygen but no blood flow, or they receive blood flow but no oxygen due to obstruction somewhere in the pulmonary circulation. This causes a decreased area for oxygen exchange.
Response Feedback: [None Given]
  • Question 7

1 out of 1 points

A 45-year-old woman is 10 days status post partial small bowel resection for Crohn Disease and has been recuperating at home. She suddenly develops severe shortness of breath, becomes weak, and her blood pressure drops to 80/40 mmHg (previous readings ~130/80s mmHg). The pulse oximetry is 89% on room air. While waiting for the Emergency Medical Service (EMS) to arrive, the APRN places EKG leads and the EKG demonstrates right ventricular strain.

 

Question:

 

Explain why a large pulmonary embolism causes right ventricular strain.

Selected Answer: The ventilation/perfusion mismatch caused the release of inflammatory mediators resulting to vasoconstriction of the pulmonary system obstructing oxygenation and subsequent hypertension. This causes atelectasis and makes pumping of blood by the right ventricle difficult
Correct Answer: The V/Q mismatch causes release of neurohumeral substances and inflammatory mediators that cause vasoconstriction of the pulmonary vasculature further impeding oxygenation. Hemodynamically, this vasoconstriction results in pulmonary hypertension, making it difficult for the right ventricle to pump blood. The V/Q mismatch also causes decreased production of surfactant causing atelectasis that further decreases surface area available for oxygen exchange.

  • Question 8

2 out of 2 points

A 12-year-old girl is brought to the Emergency Room (ER) by her mother with complaints of shortness of breath, wheezing, tachypnea, tachycardia, and a non-productive cough. The mother states they had just come from a fall festival where the entire family enjoyed a hayride. The symptoms began shortly after they left the festival but got better a couple hours after they returned home. The symptoms began again about 6 hours later and seem to be worse. The mother states there is no history of allergies or frequent respiratory infections. The child is up to date on all vaccinations. The child was diagnosed with asthma. The nurse practitioner explained to the mother that her child was exhibiting symptoms of asthma, and probably had an early asthmatic response and a late asthmatic response.

 

Question 1 of 2:

 

Explain early asthmatic responses and the cells responsible for the responses.

Selected Answer: There is an adaptive and innate immune response following an initial airway exposure to an antigen. Basophils, T helper cells, eosinophils, dendritic cells, and mast cells can initiate the inflammatory process. This process can peak at thirty minutes and resolve after three hours.
Correct Answer: When there is an initial airway exposure to an antigen, an innate and adaptive immune response is initiated. Cells that can initiate the inflammation of the bronchial mucosa and hyperresonance of the airways include dendritic cells, T helper 2 lymphocytes, B lymphocytes, mast cells, neutrophils, eosinophils, and basophils. Early asthmatic response is a phase of bronchospasm that peaks at about 30 minutes and usually resolves after about 3 hours.

A 12-year-old girl is brought to the Emergency Room (ER) by her mother with complaints of shortness of breath, wheezing, tachypnea, tachycardia, and a non-productive cough. The mother states they had just come from a fall festival where the entire family enjoyed a hayride. The symptoms began shortly after they left the festival but got better a couple hours after they returned home. The symptoms began again about 6 hours later and seem to be worse. The mother states there is no history of allergies or frequent respiratory infections. The child is up to date on all vaccinations. The child was diagnosed with asthma. The nurse practitioner explained to the mother that her child was exhibiting symptoms of asthma, and probably had an early asthmatic response and a late asthmatic response.

Question 2 of 2:

Explain late asthmatic responses and the cells responsible for the responses.

Selected Answer: Early exposure in the initial phase mediate late asthma responses resulting to the release of inflammatory mediators such as prostaglandins D  and leukotrienes  with subsequent  edema, bronchospasms, and  secretion of mucus that obstruct the flow of air. With continuous obstruction, resistance sets in and air is trapped hence reduced lung perfusion and ventilation.
Correct Answer: Late asthmatic responses are mediated by earlier exposure in early phase that causes a latent release of inflammatory mediators. These mediators, leukotrienes and prostaglandin D, cause bronchospasm, edema, and mucus secretions that obstruct airflow. Airway obstruction creates resistance to airflow and causes air trapping. Continued air trapping increases intrapleural and alveolar gas pressure, decreases ventilation and perfusion leading to uneven and variable ventilation/perfusion in the lung

  • Question 10

2 out of 2 points

A 64-year-old man with a 40 pack/year history of cigarette smoking has been diagnosed with emphysema.  He asks the APRN if this means he has COPD.

Question 1 of 2:

Explain the pathophysiology of emphysema and how it relates to COPD.

Selected Answer: Emphysema causes the permanent airway enlargement characterized by damage to alveolar walls. With continuous exposure to irritants, there is an inflammatory oxidative stress involving lymphocytes, neutrophils, and macrophages causing more alveoli damage. This process reduces the surface area required for the exchange of gases with a significant ventilation/perfusion mismatch.
Correct Answer: Emphysema is a disease of the airways that causes permanent enlargement of the gasexchange airways. It is accompanied by destruction of the alveolar walls do not appear to be fibrotic. Chronic exposure to irritants recruit neutrophils, macrophages, and lymphocytes to the lung resulting in progressive damage from inflammatory oxidative stress. Emphysema is characterized by destruction of alveoli leading to decreased surface area for gas exchange that causes significant ventilation/perfusion mismatch.

A 64-year-old man with a 40 pack/year history of cigarette smoking has been diagnosed with emphysema.  He asks the APRN if this means he has COPD.

Question 2 of 2:

Explain the pathophysiology of chronic bronchitis and how it relates to COPD.

Selected Answer: The bronchi becomes inflamed when an individual inhales irritants. Inflammation increases the number and size of   goblet cells and mucus glands, causes edema of the bronchial, and hypertrophy of the smooth muscles. Over time, the airway undergoes fibrosis and narrows. Since the functioning of the ciliary is also impaired, continuous mucus production hinders the patient’s ability to cough.  In the advanced stages, both the large and small airways get involved, with an obstructed airflow during expiration that can result to a VQ mismatch.
Correct Answer: Chronic bronchitis is caused by inhalation of irritants that promote bronchial inflammation. This inflammation causes bronchial edema, increase in the size and number of mucus glands and goblet cells, smooth muscle hypertrophy with fibrosis and narrowing of the airway. Increased secretions of thick mucus happen, and the patient cannot cough it up due to impairment of ciliary function. As the disease, progresses, the smaller airways are involved as well as the large airways. These airways, due to hypertrophy, cause narrowing of the smooth muscle and obstruct airflow, especially during expiration. The obstruction can lead to VQ mismatches.

  • Question 12

1 out of 1 points

Mr. Jones is a 78-year-old gentleman who presents to the clinic with a chief complaint of fever, chills and cough. He also reports some dyspnea. He has a history of right sided CVA, COPD, dyslipidemia, and HTN. Current medications include atorvastatin 40 mg po qhs, lisinopril, and fluticasone/salmeterol. He reports more use of his albuterol rescue inhaler.

 

Vital signs Temp 101.8 F, pulse 108, respirations 21. PaO2 on room air 86% and on O2 4 L nasal canula 94%. CMP WNL, WBC 18.4. Physical exam reveals thin, anxious gentleman with mild hemiparesis on left side due to CVA. HEENT WNL except for diminished gag reflex and uneven elevation of the uvula, CV-HR 108 RRR without murmurs, rubs, or click, no bruits. Resp-coarse rhonchi throughout lung fields. CXR reveals consolidation in right lower lobe. He was diagnosed with community acquired pneumonia (CAP).

Question:

 

Patient was hypoxic as evidenced by the low PaO2. Explain the pathologic processes that caused this patient’s hypoxemia.

Selected Answer: Continuous flow of blood in the pulmonary artery results to lung consolidation with a subsequent V/Q mismatch. This process influences the release of mediators with an inflamed bronchi-alveolar membrane. However, when the surfactant becomes inactivated, the alveoli collapses, and gets filled with exudates which decreases the surface area for the exchange of   gases.
Correct Answer: Arterial hypoxemia early in acute pneumococcal pneumonia is principally caused by persistence of pulmonary artery blood flow to be consolidated lung resulting in an intrapulmonary shunt, and by ventilation-perfusion mismatch later. Release of mediators cause widespread inflammation of the bronchial structures, especially the alveolarcapillary membrane. The alveoli collapse due to inactivation of surfactant and the alveoli fill with exudate, decreasing surface area for gas exchange.

  • Question 13

1 out of 1 points

A 64-year-old woman with moderately severe COPD comes to the pulmonary clinic for her quarterly checkup. The APRN reviewing the chart notes that the patient has lost 5% of her body weight since her last visit. The APRN questions the patient and patient admits to not having much of an appetite and she also admits to missing some meals because it “takes too much work” to cook and consume dinner.

 

Question:

 

The APRN recognizes that COPD has a deleterious effect on patients. Explain why patients with COPD are at risk for malnutrition.

Selected Answer: Most patients diagnosed with COPD are malnourished since they require a diet that is low in carbohydrates to prevent hypercapnia that may occur from the metabolism of CHO.
Correct Answer: Many of the patients with severe COPD are lean, and frequently in a malnourished or undernourished state, which is characterized by loss of fat-free body mass causing muscle wasting. The muscle wasting in COPD not only leads to decreased skeletal muscle function associated with reduced exercise capacity but is also a major determinant of mortality in COPD. Patients with COPD require a low carbohydrate diet as increased CHO can lead to hypercapnia as the end products of CHO metabolism are CO2 and H2O.

Review Test Submission: Module 2 Knowledge Check

 

The circulatory system and the respiratory system are powerful partners in health. While they work closely together in good health, a disease or disorder that manifests in one can have a significant impact on both, hampering the pair’s ability to collaborate.

Cardiovascular and respiratory disease and disorders are among the most common reasons for hospital visits, and among the leading causes of fatality. Heart disease and pneumonias are among the most familiar, but a wide variety of issues can impact physiological functioning of one or both systems.

This week, you examine fundamental concepts of cardiovascular and respiratory disorders. You explore common diseases and disorders that impact these systems, and you apply the key terms and concepts that help communicate the pathophysiological nature of these issues to patients.

A 81-year-old obese female patient who 48 hours post-op left total hip replacement. The patient has had severe nausea and vomiting and has been unable to go to physical therapy. Her mucus membranes are dry. The patient says the skin on her left leg is too tight. Exam reveals a swollen, tense, and red colored calf. The patient has a duplex ultrasound which reveals the presence of a deep venous thrombosis (DVT).

Question:

1.Given the history of the patient explain what contributed to the development of a deep venous thrombosis (DVT)

Selected Answer: given patient history factors that may contribute to her developing deep vein thrombosis, age, surgery, immobility, and dehydration
Correct Answer: Virchow’s Triad caused damage to the walls of the vessels. When there is injury to the intimal layer of the vessel, antiplatelet substances such as nitric oxide and prostacyclin, along with the expression of collagen on the vessel wall, causes adherence of the platelets to the vessel wall. The platelets become activated then aggregate forming clots. Venous stasis because of obesity, patient’s advanced age and inability to go to physical therapy.

4 out of 4 points

Scenario 5:  COPD

A 66-year-old female with a 50 pack/year history of cigarette smoking had a CT scan and was diagnosed with emphysema.  He asks if this means he has chronic obstructive pulmonary disease (COPD).

Question:

1.There is a clear relationship between emphysema and COPD, explain the pathophysiology of emphysema and the relationship to COPD.

Selected Answer: Emphysema is one of the lung conditions included in the term COPD. Normal lung tissue resembles a sponge; however, the lungs of people with emphysema look like an old used sponge, with large holes in them and a limited ability to “spring-back” into shape.

Emphysema is a progressive disease, that usually starts slowly with small holes between the alveoli, which eventually collapse to form larger air spaces. Old air gets trapped in these air spaces, which makes it difficult for people to inhale fresh air. Blood flow through the alveoli is also impaired meaning that people with emphysema not only struggle to breathe but have trouble receiving enough oxygen.

Cigarette smoking is by far the biggest cause of emphysema, but also the most preventable. Emphysema is more common with age and in males, and it tends to run in families. Other causes include air pollution, airway reactivity, and a deficiency of alpha-1-antitrypsin.

The main difference between emphysema and COPD is that emphysema is a progressive lung disease caused by over-inflation of the alveoli and COPD is an umbrella term used to describe a group of lung conditions emphysema is one of them. A person with emphysema has COPD; however, not everybody with COPD has emphysema.

Correct Answer: Emphysema is a disease of the airways that causes permanent enlargement of the gas exchange airways. It is accompanied by destruction of the alveolar walls do not appear to be fibrotic. Chronic exposure to irritants recruit neutrophils, macrophages, and lymphocytes to the lung resulting in progressive damage from inflammatory oxidative stress. Emphysema is characterized by destruction of alveoli leading to decreased surface area for gas exchange that causes significant ventilation/perfusion mismatch.

Sample Answer 4 for NURS 6051 Knowledge Check: Cardiovascular And Respiratory Disorders

Question 1

2 out of 2 points

CC: “I have been having terrible chest and arm pain for the past 2 hours and I think I am having a heart attack.”

HPI: Mr. Hammond is a 57-year-old African American male who presents to the Emergency Department with a chief complaint of chest pain that radiates down his left arm. He states that he started having pain several hours ago and says the pain “it feels like an elephant is sitting on my chest”. He rates the pain as 8/10. Nothing has made the pain better or worse. He denies any previous episode of chest pain. Denies nausea, dyspnea, or lightheadedness. He was given 0.4 mg nitroglycerine tablet sublingual x 1 which decreased, but not stopped the pain.

Lipid panel reveals Total Cholesterol 324 mg/dl, high density lipoprotein (HDL) 31 mg/dl, Low Density Lipoprotein (LDL) 122 mg/dl, Triglycerides 402 mg/dl, Very Low-Density Lipoprotein (VLDL) 54 mg/dl

His diagnosis is an acute inferior wall myocardial infarction.

1 of 2 Questions:

Why is HDL considered the “good” cholesterol?

Selected Answer: HDL carries between 20-25% of the total cholesterol in plasma. It is a good cholesterol since it accumulates the excess cholesterol that exists in body cells for excretion in the liver.
Correct Answer: HDL is considered the good cholesterol because it collects excess cholesterol in the body cells and transports it to the liver where it is excreted in the body cells and transports it to the liver where it is excreted in the body. HDL carries 20-25% of total plasma cholesterol.

His diagnosis is an acute inferior wall myocardial infarction.

2 of 2 Questions:

Explain the role inflammation has in the development of atherosclerosis.

Selected Answer: Mitochondrial damage caused by chronic inflammatory processes cause inflammation in the heart muscles. These processes cause an increase in the production of free radicals that activate the continuous cycle of chronic inflammation.
Correct Answer: Inflammation in the heart muscle caused by chronic inflammatory processes leads to mitochondrial damage that results in an increased free radical production that further activates the chronic inflammatory vicious cycle.
