ANAT 102 University of Maryland High Density Lipid & Plaque Development Discussion
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. Why is HDL considered the “good” cholesterol? Explain the role inflammation has in the development of atherosclerosis. 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? 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). 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. QUESTION 6 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. Explain why a large pulmonary embolus interferes with oxygenation. QUESTION 7 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. QUESTION 8 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. QUESTION 9 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. QUESTION 10 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. QUESTION 11 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. QUESTION 12 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. QUESTION 13 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.

In these calculations, the Coulomb constant has a value of 8.99×109N⋅m2C28.99×109N⋅m2C2Part I (Label the tab "macro"): This is the macroscopic data. Note that: q1=q2=q.q1=q2=q. Starting in cell D2, record all of your force measurements down the D column. In cell A1, record the initial position of q1. In cell A2, record the initial position of q2. The difference in those positions is the first separation between the charges. Place this value in B2. In cell B3, type (without quotes) "B2+0.1". Hit enter. Copy the formula down to the last force measurement. Finally, in cell C2, type "B2/100", and copy the formula down.1.Place column labels in cell 1. In cell C1, it is r(m)r(m). In D1, it is F(N)F(N).2. Plot F(r)vs.rF(r)vs.r . Make sure you insert the correct graph! It looks like in inverse-square curve. Label the graph for presentation. Afterwards, run a trendline by right-clicking the data. Chose power fit. Place the equation on the graph and enhance the size. Note the power of the fit. Record and label on the spreadsheet close to the graph the power obtained and the coefficient. Note: Do NOT run a LINEST or linear fit here!!!!!For this analysis, using the Coulomb equation and this coefficient, calculate q. Record this value in SI based units as well as in micro-Coulombs.Part II (Label a new tab "micro"): You are given that q2=4eq2=4e. Note that this scale is now in picometers.Starting in cell D2, record all of your force measurements down the D column. In cell A1, record the initial position of q1. In cell A2, record the initial position of q2. The difference in those positions is the first separation between the charges. Place this value in B2. In cell B3, type (without quotes) "B2+0.1". Hit enter. Copy the formula down to the last force measurement. Finally, in cell C2, convert first value to meters, and copy the formula down.1.Place column labels in cell 1. In cell C1, it is r(m)r(m). In D1, it is F(N)F(N).2. Plot F(r)vs.rF(r)vs.r . Make sure you insert the correct graph! It looks like in inverse-square curve. Label the graph for presentation.

Record and label on the spreadsheet close to the graph the power obtained and the coefficient. Note: Do NOT run a LINEST or linear fit here!!!!!For this analysis, using the Coulomb equation and this coefficient, calculate q1q1. Record this value in SI based units as well as in micro-Coulombs. Also, record the polarity. Is it is negative or positive ion? How do you know?4. Plot F(r)vs.1r2F(r)vs.1r2. Is it linear? Label the graph for presentation. Run a LINEST by highlighting a 2 x 5 matrix starting around cell A15 or so. Record the value of the slope and the uncertainty (e.g. 2.5±0.12.5±0.1).For this analysis, using the slope and the Coulomb constant, calculate q1q1. Record this value in SI based units as well as in micro-Coulombs. Also, compare with your first calculation and comment.Part III (Create a tab called "summary"): Insert large text boxes to type in. In the summary tab, address these questions:From the data (you) collected, does the power fit indeed illustrate the inverse-square Law?Suppose you placed another charge (q3q3) on the opposite end of the ruler of (a) equal value as q1q1 and with the same sign and (b) a charge q3=2q1q3=2q1 .Describe how the force on q2q2 would look as a function of position starting at the original point as before, and then moving towards the right for both scenarios (a) and (b)? Analyze one scenario at a time! Take a stab at it. How would you begin to investigate this?Suppose you were in a lab doing these measurements, assuming well-calibrated equipment, list some random errors you would encounter.Save the file and upload.
