Chapter 15, Problem 35CAQ
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?

Joey complained to his physician that he was constantly thirsty, hungry, and had to urinate frequently. His physician ordered a blood and urine test. The results of his urinalysis showed the following abnormal values:
pH: 3.5
glucose: 250 mg/100 mL
ketones: 10 gm/100 mL
albumin: 30 mg/100 mL
specific gravity: 1.045
Given Joey’s symptoms and urinalysis results, what do you predict is his diagnosis? Explain and provide reasoning
For the past several months, a 24-year-old male has experienced fatigue, puffiness, and overall weakness.
One day he noticed his urine had a red to brown discoloration, and that his urine volume was minimal. He
went to the emergency room, where urinalysis, blood work, and other tests were done to obtain the
following data:
