B) sympathetic nervous system
C) somatic nervous system
D) parasympathetic nervous system - CORRECT ANSWER-Ans: B- sympathetic nervous system
When renin is released, it is capable of which action?
A) inactivation of autoregulation
,B) direct activation of angiotensin II
C) direct release of antiduretic hormone (ADH)
D) formation of angiotensin I - CORRECT ANSWER-Ans: D- formation of angiotensin I
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
D) inhibition of renin and aldosterone - CORRECT ANSWER-Ans: D- inhibition of renin and
aldosterone
What is the direct action of atrial natriuretic hormone?
A) sodium retention
B) sodium excretion
C) water retention
D) water secretion - CORRECT ANSWER-Ans: B- sodium excretion
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 - CORRECT ANSWER-Ans: C- tubular reabsorption
, 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 extracellular volume
D) urodilatin is stimulated by a fall in blood pressure and a decrease in extracellular volume -
CORRECT ANSWER-Ans: C- urodiatin is stimulated by a rise in blood pressure and an increase in
extracellular volume
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 - CORRECT ANSWER-Ans: C- the
specific gravity of urine in older adults is considered low normal
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
C) potassium attaches to receptors on the cell membrane of glucose and is carried into the cell
D) increasing insulin causes ketoacidosis, which causes potassium to move into the cell in
exchange for hydrogen - CORRECT ANSWER-Ans: B- when insulin transports glucose into the
cell, it also carries potassium with it
