MIDTERM 2: Renal And Urinary System

Question 0

How would giving a patient intravenous albumin affect filtration?
A) due to higher on optic pressure, the net filtration pressure would be lower
B) too much protein in the diet would abolish all filtration
C) high blood pressure from increased plasma proteins would increase filtration to twice it’s normal rate
D) filtration would be unchanged, but the kidneys would suffer damage

Answer 0

A) due to higher on optic pressure, the net filtration pressure would be lower

Question 1

If you suddenly became emaciated, what might happen to your kidneys?

Answer 1

Kidney might drop lower: renal ptosis

Prevent urine to leave kidney: hydronephrosis

Question 2

What would the glomerular filtration rate be if blood pressure were very low?

Answer 2

0

Anuria, abnormally low urinary output (<50mL/day)

Question 3

What would happen if there is a great excess of glucose in the blood?

Answer 3

End up in filtrate
Transporters would saturate and not all if glucose would be reabsorped
Glucose would end up in urine
Diabetes mel litmus (sweet urine)

Question 4

Why is glucose in the urine an indicator of diabetes mellitus?

Answer 4

Blood glucose is very high, filtered glucose occupies all transport carriers and no longer reabsorbed

Question 5

What would be the effect on urine output if sodium channels in the tubule cells were inhibited?
A) the volume would increase
B) the volume would decrease
C) the volume would not change

Answer 5

A) the volume would increase

Question 6

What might cause blood in the urine
A) deficits in filtration
B) damage to the kidneys tubules 
C) damage to the bladder
D) all of the above

Answer 6

D) all of the above

Question 7

Alcohol acts as a a diuretic because it
A) inhibits the release of ADH
B) increases the release of ADH

Answer 7

A) inhibits the release of ADH

Question 8

Where is filtrate produced in the nephron
A) glomerulus
B) juxtaglomerular complex
C) vasa texts
D) peritubular capillaries

Answer 8

A) glomerulus

Question 9

Which of the following is the most likely to cause pyelonephritis 
A) increased blood flow to the kidneys
B) decreased blood flow to the kidneys
C) renal failure
D) infection of the urinary bladder

Answer 9

D) infection of the urinary bladder

Question 10

The macula densa cells respond to
A) changes in pressure in the tubule
B) changes in solute content if the filtrate

Answer 10

B) changes in solute content if the filtrate
