Textbook Question
Chapter 15, Problem 36CT
Mr. Jessup, a 55-year-old man, is operated on for a cerebral tumor. About one month later, he complains that he is excessively thirsty and that he has been voiding almost continuously. A urine sample is collected, and its specific gravity is 1.001. What is your diagnosis of Mr. Jessup’s problem, and how might it be related to his previous surgery?

- John Smith joined a Triathlon for a cause. The triathlon consisted of a 1.5 km swim, 40 km bike ride and a 10 km run. He was so focused on winning the race. With 6 km left in the run, he felt very weak and light-headed and eventuallly collapsed. He was breathing so fast and was profusely sweating. The Emergency Medical Service on standby rushed to give him medical aid. a.) Discuss the role of electrolytes in this case. b.) What imbalances (Hypernatremia vs. Hyponatremia; Hyperkalemia vs. Hypokalemia) led to his condition? Justify.arrow_forwardHenry is in the intensive care unit because he suffered a severe myocardial infarction three days ago.
