1
Q
What is a normal urine pH?
A
4.5-8
2
Q
What is a normal urine flow per minute?
A
1ml/min
3
Q
What is a normal Na+/K+ output?
A
100umol/min
4
Q
What is a normal urine osmolality output?
A
600umol/min
5
Q
If osmolality cannot be measured directly, what can give an approximate measure and why?
A
2([K+]+{Na+]) + [urea]
Osmolality is due to cations (Na+ and K+) and anions.
Anions conc = cation conc
The rest is due to urea
6
Q
Within 90, how is urine flow affected by isotonic saline ingestion?
A
doesn’t change
