3

A 45 year old woman develops severe diarrhea while on vacation. She has the folllowing arterial blood values

pH= 7.25

PCO2 = 24

HCO3 = 10

Venous blood samples show decreased blood K adn normal anion gap

the correct diagnosis is ______

Metabolic acidosis

4

A 45 year old woman develops severe diarrhea while on vacation. She has the folllowing arterial blood values

pH= 7.25

PCO2 = 24

HCO3 = 10

Venous blood samples show decreased blood K adn normal anion gap

 

Patients low potassium is a result of increased circulatin levels of aldosterone

5

Glomerular  capillary pressure = 47mmHg

Bowman space hydrostatic pressure = 10 mmHg

Bowman space oncotic pressure = 0 mmHg

At what value of glomerular capilalry oncotic pressure would glomerular filtration stop?

37 mmHg

 

6

The reabsorption of filtered HCO3

inhibited by decrease in arterial PCO2

7

There is net reabsorption of X

8

To maintain normal H balance, total daily escretion of H should equal the daily 

Fixed acid production plus fixed acid ingestion

9

One gram of mannitol was injected into a woman, after equilibration,a plasmasample had a mannitol concentration of 0.08 g/L. During thr equilibratio period, 20% of the injected mannitol was excreted in the urine. The woman's 

ECF volume is 1

 

10

a 58 year old man is given a glucose tolerance test. In the test, the plasma glucose concentration is increased and glucose reabsorption and excretion are emasured. When the plasma glucose concentration is higher than occures at transport maximum the __________

Excretion rate of glucose increases with increasing plasma glucose

11

A negative free water clearance will occur in a person who 

Has an oat cell carcinoma of the lung and excretes urine with an osmolarity of 1000 mOsm/L
