Case Study 1
Structure and Function of the Respiratory System
Brad is 45 years old and has been working as a coal cutter in a mine for the last 25 years. He likes the job because it pays well and the same mine had employed his father. Like many of his colleagues, Brad has had problems with a chronic cough. He has avoided his annual checkups for fear that he will be told he has “black lung,” or coal worker’s pneumoconiosis. The disease causes fibrosis, decreased diffusing capacity, and permanent small airway dilation. In later stages, pulmonary capillaries, alveoli, and airways are destroyed. MN551 Case Study Assignment Essay Papers.

- Individuals with chronic obstructive pulmonary disease have more difficulty exhaling than inhaling. Why is this so?
- In general terms, what mechanisms in lung disease can affect diffusing capacity across alveolar membranes? Use the Fick law to explain your answer.
Case Study 2
Respiratory Tract Infections, Neoplasms, and Childhood Disorders
Patricia was called at work by a woman at the local daycare center. She told Patricia to come and pick up her son because he was not feeling well. Her son, three-and-a-half-year-old Marshall, had been feeling tired and achy when he woke up. While at daycare, his cheeks had become red and he was warm to touch. He did not want to play with his friends, and by the time Patricia arrived, he was crying. Later that afternoon, Marshall’s condition worsened. He had fever, chills, a sore throat, runny nose, and a dry hacking cough. Suspecting Marshall had influenza, Patricia wrapped him up and took him to the community health care clinic
- Why did Marshall’s presentation lead Patricia to think he had influenza and not a cold? Why is it important to medically evaluate and diagnose a potential influenza infection?
- Describe the pathophysiology of the influenza virus. Outline the properties of influenza A antigens that allow them to exert their effects in the host.
- Marshall may be at risk at contracting secondary bacterial pneumonia. Why is this so? Explain why cyanosis may be a feature associated with pneumonia.
Case Study 3
Disorders of Ventilation and Gas Exchange
Emmanuel and his mother live in an urban community housing complex. The building is worn down and dirty from the urban dust, cockroaches, and mold. Emmanuel is five years of age and has suffered from asthma for the last two years. One evening, his mother poured him some milk and put him to bed. Shortly afterward, Emmanuel woke up wheezing and coughing. MN551 Case Study Assignment Essay Papers. As he gasped for air, he became more and more anxious. His mother ran for his inhaler, but he was too upset and restless to use it. Emmanuel’s skin became moist with sweat, and as he began to tire, his wheezing became quieter. His mother called 911 and waited anxiously for the ambulance to arrive.
- Emmanuel uses a corticosteroid inhaler for the management of his asthma. What is the mechanism of action of this drug? How is its action different from the β2-agonist inhalants?
- Why does someone with severe asthma become physically fatigued during a prolonged attack? What are the physiological events that occur during an attack?
- One of the complications of respiratory fatigue is the development of hypercapnia. How does the body compensate for an increase in CO2? What are the effects of hypercapnia on the central nervous system?

Case Study 4
Inflammation, Tissue Repair, and Wound Healing
Carlton, a six-year-old boy, was playing on a sandy beach with his mother. He began to run along the shoreline when he stepped on the sharp edge of a shell, giving himself a deep cut on his foot. His mother washed his foot in the lake and put on his running shoe to take him home. One day later, Carlton’s foot looked worse. The gash was red and painful. The foot was warm to touch and appeared swollen. Carlton’s mom put some gauze over the wound and prepared to take him to the local community health clinic.
What is the physiologic mechanism causing the wound to become red, hot, swollen, and painful? How is this different than the inflammatory response that might occur in an internal organ?
What are the immunologic events that are happening at the local level during Carlton’s acute inflammatory response?
Nutrition plays an important factor in wound healing. What stages of wound healing would be affected by a deficiency in vitamins A and C?
Case Study 5
Acquired Immunodeficiency Syndrome
Patience is 29 years old and has been HIV positive for nine years. She has remained asymptomatic and is not taking antiretroviral medication. Recently she was at the drop-in clinic to talk to a public health nurse about having a baby through artificial insemination. She said she had met a man who wanted to marry her and have children with her, but she was concerned about the baby contracting HIV. Her latest blood tests indicated her CD4+ count was 380/µL. The PCR test indicated her viral load was 850. The nurse referred her to the physician to discuss antiretroviral therapy during her pregnancy.
What are the factors that increase the chance of HIV transmission from mother to infant, and how the transmission occurs?
Patience was told that after she became pregnant, she would begin HAART therapy. Describe what this therapy is and what particular antiretroviral medication would be particularly useful to her during her pregnancy. What concern is there about administering certain antiretrovirals early in the pregnancy?
Individuals with HIV are prone to contracting opportunistic infections. What are opportunistic infections and the risk factors that leave an individual with HIV particularly prone to contracting this type of illness?
Case Study 6
Blood Cells and the Hematopoietic System
Charlie is a 53-year-old man with non-Hodgkin lymphoma. His treatment has been only modestly successful in delaying the progression of the disease, and he has recently relapsed. His medical team decided to administer aggressive chemotherapy. Knowing that the intensive treatment would have a destructive effect on Charlie’s bone marrow, they removed stem cells from his blood before the chemotherapy began. Afterward, the stem cells were returned by IV to reestablish his bone marrow function. MN551 Case Study Assignment Essay Papers,.
What are the therapeutic advantages of an autologous stem cell transplant on Charlie’s bone marrow and immune system?
Before harvesting stem cells, a cytokine growth factor is administered to the patient. What is the benefit of this procedure?
Non-Hodgkin lymphoma is a disease involving B and T lymphocytes. What aspects of the immune response are these cells responsible for?
When considering erythrocytes, how is the body able to meet hematopoietic demand in conditions such as hemolytic anemia or blood loss?
