Keeping Up With the Jones’s Case Study Essay

Part I: 1. What two parameters are responsible for creating the movement (filtration and reabsorption) of fluid across the capillary wall? 2. Find a diagram of a capillary – copy/paste and cite the source. 3. Under normal circumstances, what components of the blood cross the capillary wall? 4. Cytokines, like histamine and leukotrienes, are secreted by damaged cells in Dave’s ankle. How do these cytokines cause inflammation? 5. How does the application of ice to the ankle affect blood flow through the capillaries? 6. How does the removal of ice from the ankle affect blood flow through the capillaries and the cytokines? 7. How does compression, which is provided by an elastic (Ace) bandage wrapped around the damaged ankle, decrease inflammation? 8. How does elevation of the damaged ankle decrease inflammation? Part II: 1. What problems are there in Suzie’s life, and does she exhibit any peculiar signs and symptoms? 2. Why did Suzie pass out when she stood up? 3. Why did Suzie’s mother place Suzie’s feet on a chair? 4. Why did Suzie feel as if she had no energy at the doctor’s office? 5. Make an initial speculation about Suzie’s condition at this time. Assuming that your speculation is true, what do you think the doctor will find in the results of Suzie’s physical examination? Part III: 1. What new signs and symptoms does Suzie exhibit that would concern you if you were the doctor? 2. Do you wish to make any further speculation about Suzie’s condition at this time? Assuming that your speculation is true, what do you think the doctor will find in the results of Suzie’s physical examination? Part IV: 1. Is Suzie’s weight reasonable for her height? 2. Calculate the stroke volume of Suzie’s heart, and compare it to that of a normal individual. 3. Why do you think her blood pressure is lower than normal? Does low blood pressure explain any of Suzie’s signs and symptoms that you may have noticed? 4. Why is Suzie’s hematocrit low, and why are her red blood cells pale and immature? 5. Compared with a normal, healthy person predict the level of the following in Suzie’s blood (higher, same, lower): sodium, potassium, calcium, glucose, iron, and protein. 6. Do you wish to make any further speculation about Suzie’s condition at this time? Part V: 1. Assuming that the ion levels in the blood plasma are similar to those in the interstitial fluid, what is the effect of low potassium levels on the membrane potential of Suzie’s nerve and muscles? 2. Does this explain Suzie’s slow heart rate and ectopic beats? 3. How does low plasma calcium level account for her decreased stroke volume? 4. What is the role of blood proteins in the movement of fluid between the blood and the interstititial space? 5. What would be the effect of low blood protein levels on the colloidal pressure? 6. How do low plasma protein levels produce edema? Part VI: 1. What conditions make Suzie a candidate for anorexia? 2. Do you think the doctor’s treatment is appropriate, or would you have admitted her into hospital? 3. When do you think Suzie should schedule her next visit to the doctor?
