Pathophysiology Case Reviews

1. The name of this respiratory disease is Cor Pulmonale, also called right sided heart failure. This is a disease in which hypertrophy and dilation of the right ventricle occur secondary to diseases affecting structure or function of the lungs or their vasculature. It can occur at the end stage of various chronic respiratory and respiratory control center diseases. Cor pulmonale doesn’t occur in disorders stemming from congenital heart defects or those that affect the left side of the heart. Causes include but are not limited to; bronchial asthma, vascular obstruction, high altitude, kyphoscoliosis, obesity, pectus excavatum, poliomyelitis, pulmonary hypertension, pulmonary embolism, and vasculitis. Symptoms of the disease include dyspnea at rest, weakened pulses due to decreased cardiac output, and neck vein distention. Treatment of Cor pulmonale has three main focuses, reducing hypoxemia and vasoconstriction, increasing exercise tolerance, and correcting underlying conditions when possible.

2. Croup is severe inflammation and obstruction of the upper airway, occurring as acute laryngo-tracheobronchitis, laryngitis, and acute spasmodic laryngitis. Croup usually results from viral infection. Viruses include; adenovirus, influenza, measles, parainfluenza viruses, respiratory syncytial virus. Signs and symptoms include: inspiratory stridor, muffled vocal sounds, and a characteristic sharp barking or seal-like cough related to the degree of laryngeal obstruction. For most people diagnosed with Croup home care with rest, cool moist air and an antipyretic like acetaminophen relieves symptoms.

3. Pneumothorax is an accumulation of air within the pleural cavity which results in partial or complete lung collapse. Pneumothorax comes in three different types open, closed or tension. Causes include: chest surgery,…...

...Transformational change in organisations: a self-regulation approach Transformational change in organisations 143 Purpose – The purpose of the present paper is to advance a testable model, rooted on well-established control and self-regulation theory principles, explaining the causal links between change-related sensemaking, interpretation, readiness and subsequent behavioural action. Design/methodology/approach – Following a review of the two motivation theories and clarification of change-related sensemaking, interpretation, and readiness concepts, the paper proposes a series of research propositions (illustrated by a conceptual model) clarifying how these concepts interact with self-regulating mechanisms. In addition, the feedback model exemplifies how cognitive processes triggered by new knowledge structures relate to behavioural action. Findings – The model expands upon other existing frameworks by allowing the examination of multi-level factors that account for, and moderate causal links between, change-related sensemaking, interpretation, readiness, and behavioural action. Suggestions for future research and guidelines for practice are outlined. Practical implications – The variables and processes depicted in the model provide guidelines for change management in organisations, both for individuals and for groups. By eliciting important self-regulating functions, change agents will likely facilitate sensemaking processes, positive interpretations of change, change...

...Berlin Herrera Unit 1 Case Study F.C. is a 54-year-old man with a history of chronic heavy alcohol use. He has frequent bouts of gastrointestinal bleeding for which he has been hospitalized on six separate occasions over the years. He continues to drink and exhibits most of the common manifestations of alcoholic cirrhosis. He was recently hit by a car and was hospitalized for a broken leg. He appeared to be under the influence of alcohol at the time of the accident and had a blood alcohol level of 0.18. F.C.’s family reports that his mental functioning has deteriorated significantly over the past few months.  Discussion Questions 1. What are the common manifestations of alcoholic cirrhosis? Which of these are secondary to hepatocellular failure? Which are secondary to portal hypertension? Common manifestations of alcoholic cirrhosis are as follows: * Jaundice: yellow pigmentation of the skin caused by hyperbilirubinemia. This condition is secondary to hepatocellular failure because the bilirubin metabolism becomes impaired due to malfunction of liver tissue. * Spontaneous Bacterial Peritonitis: acute bacterial infection of ascetic fluid caused by contamination of dialysate. This condition is considered secondary to portal hypertension because the normally, the fluid passes the portal vein into the liver to be killed off, but with a fluid back up, bacterial infection grows due to the increased fluid retention within the portal vein. * Hepatic......

He suffered a frontal contusion, fractured clavicle and ribs, and extensive abrasions on his arms, legs, side, back, and buttocks. He was tachycardic, hypotensive, unresponsive, and ventilating poorly when admitted. He was placed on a mechanical ventilator and given IV fluids for shock. C.C. responded well to fluids, with an increase in blood pressure and an improvement in urine output. 1. Based on his case history and responsiveness to fluid therapy, what type of shock was C.C. experiencing? Hypovolemic shock 2. What other clinical findings would be helpful in confirming the type of shock? Capillary refill, tenting on skin turgor, pale skin due to perfusion, and may feel dizzy, faint, nauseated, or very thirsty. 3. Because of his many open wounds and invasive lines, C.C. is at risk for sepsis and septic shock. What clinical findings would suggest that this complication has developed? Bacteremia, high fevers, hot, flushed skin, elevated heart rate, hyperventilation, altered mental status, swelling, and low blood pressure 4.

...Case Study Review Rebekah Gardner BSHS 335 November 04, 2015 Stephanie Chupein Case Study Review A father arrives at the Methodist Hospital with his six-year-old son Tavion Robinson. Tavion is suffering from a broken arm and abrasions. Tavion’s father advises the hospital that Tavion fell from the jungle gym at the park. Tavion’s father displays reluctance to Tavion being left alone with hospital staff. Emergency room staff suspects that Tavion’s injuries did not happen as his father reported because the abrasions were too clean. Tavion’s abrasions would not have been so clean if brought in immediately after his fall from the jungle gym. While Tavion was undergoing his x-ray, the staff did not allow Tavion’s father in the room, and they were able to question Tavion about his injuries. Tavion verified his father’s story and consistently denied and abuse or fear of his father. Before leaving the hospital, Tavion’s father advises the staff to make note that he should be notified before the release of Tavion’s records to anyone. Tavion’s father advises that Tavion’s parents are divorced and that Tavion’s mother is the noncustodial parent. Tavion’s father requests that Tavion’s records not be released to his mother without his father’s consent. The following weekend Tavion’s mother made a request to the Health Information Department for Tavion’s medical records. Tavion’s mother advises the department that she feels that Tavion’s father is abusing him, and she......

With customer breakeven in mind, did it make sense to close altogether if no private events were scheduled? Were there other options? Looking back at her experience at Sugar Bowl, Givens reflected: The past 18 months have afforded me an incredible opportunity; I’ve been exposed to general management much earlier than most of my business school classmates and for that I am grateful. I’m certainly proud of the progress we’ve made with Sugar Bowl. From the outside it would appear that our success has come from leveraging the urban lounge concept. To me, however, that’s not the case—it is the combination of careful cost management together with the new strategy that has propelled our success. My greatest accomplishment, I think, was maintaining tight cost controls through our transition. Bowling is currently experiencing a renaissance, with young professionals enjoying urban lounges like ours and families patronizing big-box entertainment centers. Yet the long term viability of either of these business types is unknown. Who knows what the next trend in entertainment will be? We’ve made a large investment in Sugar Bowl but I do worry that its novelty will be lost on future generations. Plus, I am saddled with debt and my investors are waiting for a return as well. I also wonder at what point I should pursue a......

...Patho Case Study 1 E.O. is an 8-year-old girl with a history of asthma and allergy to bee stings. She has been brought to the clinic complaining of a throat infection. Her health care provider prescribes a course of penicillin to manage her current infection and cautions her parents to watch her closely for a reaction. Discussion Questions   1. What type of reaction is the health care provider concerned about and why? The type of reaction that the health care provider is concerned about is an allergic reaction to the penicillin.   Since E.O is already allergic to bee stings and has a history of asthma, which are both Type I hypersensitivities, it is very likely that E.O could have an allergic reaction to the penicillin.   Since penicillin is found in cow milk and the patient could have been exposed to it through milk, breast milk, or in utero, E.O could become sensitized to it.   If E.O is further exposed to the allergen (being that her health care provider prescribed her penicillin), there could be an allergic reaction to it.   Exposure to penicillin can result in the degranulation in mast cells and the release of histamine, which could cause the reaction, which is even more likely since E.O has two Type I hypersensitivities.      2. Explain the role of IgE and mast cells in type I hypersensitivity reactions. Why might E.O. react adversely to the antibiotic with the first use? During sensitization, IgE antibodies bind to the surface of mast cells, which makes the......
