Chооse ONE. (5 pts. eаch - tоtаl 5 pts). You mаy choose one extra essay from either part 2 or part 3 to complete as a bonus. Mark it as bonus **. 1.) Peggy Fender is well known to the emergency department (ED) staff. She’s a 59-year-old woman whose visit today is like her frequent visits in the past. She arrives in the afternoon, appearing intoxicated and complaining of abdominal pain, particularly in the right upper quadrant (RUQ) of her abdominopelvic cavity. Tim, the PA on call conducts a physical examination. Mrs. Fender appears emaciated with bruising of various stages on her arms, legs, and face. She is jaundiced and has the strong smell of alcohol on her breath. Tim palpates the inferior border of her liver, which is hard and enlarged; Mrs. Fender moans with pain. Her entire abdomen is ascetic. Blood tests are done and show elevated blood liver enzymes aminotransferases (ALT & AST), hyperglycemia, and prolonged prothrombin time. Based on her history and present findings, Tim diagnoses Mrs. Fender with alcoholic cirrhosis, which is the result of chronic inflammation of the liver from heavy, consistent alcohol ingestion. 1. Mrs. Fender is jaundiced. What is jaundice and why does it occur with liver disease? 2. What information is supplied by the increased AST and ALT blood levels - what does their presence in the blood indicate? 3. Mrs. Fender’s prolonged clotting times and excessive bruising are related. Why do these two things happen when alcohol damages hepatocytes? 4. Often, an individual with liver disease exhibits increased plasma ammonia levels, why would this occur? 5. Explain why she has severe edema (third spacing). Why does it commonly occur with liver disease? 2.) Carrie Oakey is a 52-year old Caucasian female. She is 5'3" tall and weighs 195 pounds. She is the mother of four children ranging in age from 10 - 18 years and has gained weight after each of her pregnancies. She works full-time and doesn't have much time for exercise. She wants to lose weight and isn't happy with her body (she has a 39" waist). She tries to eat well but eats fast food 2 - 3X per week and claims she "lives off of diet Coke". She has been feeling tired lately and made an appointment with her doctor because a coworker told her she might have a problem with her thyroid gland. Her physician completes a physical and orders blood work. Her heart rate and blood pressure are within the normal ranges. The blood work comes back with the following abnormalities: Serum triglyceride level: 200 mg/dL, HDL cholesterol: 48 mg/dL, fasting blood glucose: 130 mg/dL - her thyroid hormone levels are within normal limits. Her doctor tells her that he thinks she has "metabolic syndrome". He explains that this syndrome can increase her risk of type II diabetes or cardiovascular disease. She is told metabolic syndrome is becoming more common and that it has also been known as "syndrome X" or "insulin resistance syndrome". She decides to research this condition on the internet to share it with others. 1. What is metabolic syndrome? (list 3 specific criteria from this case that indicate Carrie has it) 2. How can it be prevented? (list 2 specific dietary/lifestyle factors). 3. Why is it better to exercise (especially resistance training) when restricting calories and trying to lose weight? 4. How do medications such as Ozempic, Wegovy, & Zepbound cause weight loss? (what is their mechanism?) 5. How specifically does stress lead to insulin resistance?
