Art wanted to improve his performance at a local marathon. about 6 weeks prior to the event, art's doctor removed a small quantity of blood and separated it into plasma and formed elements. the plasma was injected back into art's bloodstream. the formed elements were frozen. on the day of the competition, the formed elements were thawed and injected into art's bloodstream. this process is called blood doping.
1. on the first day when blood was removed, what would this process due to art's hematocrit- increase, decrease, remain the same?
2. this hematocrit would indicate which blood disorder?
3. blood plasma is mostly made of this molecule necessary for life.
4. why would you put the blood plasma back after taking the red blood cells out?
5. you begin this procedure 6 weeks prior to the event in order to stimulate the production of which hormone?
6. the hormone from question 5 will cause the production of which blood cell- red blood cell, white blood cell, platelet?
7. why would you begin the procedure 6 weeks prior to the event?
8. when you inject the red blood cells back into art, what would happen to the hematocrit- increase, decrease, remain the same?
9. how might blood doping improve an athlete's performance on game day?

Harold, a fifty-eight year old grocery store manager, had recently been waking up in the middle of the night with abdominal pain. this was happening several nights a week. he was also experiencing occasional discomfort in the middle of the afternoon. harold decided to schedule an appointment with his physician. the doctor listened as harold described his symptoms and then asked harold some questions. he noted that harold's appetite had suffered as a result of the pain he was experiencing and as a result of the fear that what he was eating may be responsible for the pain. otherwise, harold seemed fine. the doctor referred harold to a physician that specialized in internal medicine and had harold make an appointment for a procedure called an endoscopy. the endoscopy was performed at a hospital later that week. during the procedure, a long, thin tube was inserted into harold's mouth and directed into his digestive tract. the end of the tube was equipped with a light source and a small camera which allowed the doctor to observe the interior of harold's stomach. the endoscope was also equipped with a small claw-like structure that the doctor could use in order to obtain a small tissue sample from the lining of harold's stomach, if required. the endoscopy revealed that harold had a peptic ulcer. analysis of a tissue sample taken from the site showed that harold also had an infection that was caused by helicobacterpylori bacteria. the doctor who performed the endoscopy gave harold prescriptions for two different antibiotics and a medication that would decrease the secretion of stomach acid. the doctor also instructed harold to schedule an appointment for another endoscopy procedure in 6 months. 1. list the subjective findings in this case study. 2. what is an endoscopy? (2 points) what is a biopsy? 3. how was a biopsy performed on harold? 4. differentiate between gastric and duodenal ulcers by location. 5. what role does h. pylori play in the formation of peptic ulcers? 6. define occult and frank blood. (4 points) what is a guaiac test? 7. how can peptic ulcers cause bleeding? 8. why were antibiotics prescribed? 9. why would a medication that would decrease the secretion of stomach acid be beneficial?
