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
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
The reabsorption of filtered HCO3
inhibited by decrease in arterial PCO2
There is net reabsorption of X
To maintain normal H balance, total daily escretion of H should equal the daily
Fixed acid production plus fixed acid ingestion
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
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
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
A buffer pair has a pK of 5.4. At a blood pH of 7.4 the concentration of HA is
1/100 that of A
Increased filtration fraction
The following substance could be used to measure intestital fluid volume
Inulin and radiactive albumin
At plasma PAG concentrations below the transport maximum, PAH
Concentration in the renal vein is close to zero
