1. What effects do exercise and body position have on renal blood flow?
A) they activate renal parasympathetic neurons and cause mild vasoconstric-
tion
B) they activate renal sympathetic neurons and cause mild vasoconstriction
C) both activate renal parasympathetic neurons and cause mild vasodilation
D) they activate renal sympathetic neurons and cause mild vasodilation: Ans: B-
they activate renal sympathetic neurons and cause mild vasoconstriction
2. Blood vessels of the kidneys are innervated by the:
A) vagus nerve
B) sympathetic nervous system
C) somatic nervous system
D) parasympathetic nervous system: Ans: B- sympathetic nervous system
3. When renin is released, it is capable of which action?
A) inactivation of autoregulation

4. Which effect does natriuretic peptides have during heart failure when the
heart dilates?
A) stimulation of antiduretic hormone (ADH)
B) inhibition of ADH
C) stimulation of renin and aldosterone

6. Which term is used to identify the movement of fluids and solutes from the
tubular lumen to the peritubular capillary plasma?
A) tubular secretion
B) ultrafiltration
C) tubular reabsorption
D) tubular excretion: Ans: C- tubular reabsorption
7. Which statement is true regarding urodilatin?
A) urodilatin inhibits sodium chloride and water reabsorption in the medullary
part of the collecting duct
B) urodilatin ibhibits antidiuretic hormone (ADH) to prevent water reabsorption
in the medullary part of the collecting duct
C) urodiatin is stimulated by a rise in blood pressure and an increase in extra-
cellular volume
D) urodilatin is stimulated by a fall in blood pressure and a decrease in extracel-
lular volume: Ans: C- urodiatin is stimulated by a rise in blood pressure and an increase in extracellular volume
8. Compared to a younger individual, how is the specific gravity fo urine in older
adults affected?
A) the specific gravity of urine in older adults is increased
B) the specific gravity of urine in older adults is considered high normal
C) the specific gravity of urine in older adults is considered low normal
D) the specific gravity of urin in older adults is decreased: Ans: C- the specific gravity of
urine in older adults is considered low normal
9. How are glucose and insulin used to treat hyperkalemia associated with acute
renal failure?
A) glucose has an osmotic effect, which attracts water and sodium, resulting in
more dilute blood and a lower potassium concentration
B) when insulin transports glucose into the cell, it also carries potassium with
it
