Which is not a use for loop diuretics?
a) HTN
b) edema
c) pulmonary edema
d) diabetes insipidus
Answer: d) diabetes insipidus
Loop diuretics good in renal impaired patients and for those who have been unresponsive to other diuretics
Which diuretic produces the most fluid and electrolyte loss?
loop diuretics
Which is not a SE of loop diuretics:
a) hypoglycemia
b) hyponatremia
c) hyperkalemia
d) ototoxicity
e) one or more of the above
Answer: e) one or more of the above
SE: hyponatremia, hypochloremia, dehydration, hypokalemia, hypotension, OTOTOXIC, HYPERGLYCEMIA, hyperuricemia, lipid metabolism issues
What relationship can loop diuretics have with digoxin?
Digoxin toxicity due to loss of K (potassium)
If lithium and loop diuretics are administered in the same patient, what can happen?
a) lithium levels rise dangerously
b) lithium levels are not therapeutic (low)
c) loop diuretics can become toxic (high)
d) loop diuretics are not effective
Answer: a) lithium can rise dangerously due to decreased renal excretion
______ diuretic produces maximal diuresis compared to ______ diuretics. However ______ diuretics can be effective even when urine flow is decreased, whereas ______ diuretics are not.
choices: loop, thiazide, osmotic, potassium sparing
Loop diuretic produces maximal diuresis compared to thiazide diuretics. However thiazide diuretics can be effective even when urine flow is decreased, whereas loop diuretics are not.
Which is NOT a side effect of thiazide diuretics?
a) hyponatremia
b) hypokalemia
c) hyperglycemia
d) ototoxicity
Answer: d)ototoxicity
Loop diuretics however are ototoxic.
Which is not a loop diuretic?
a) torsemide
b) ethacrynic acid
c) amiloride
d) bumetide
Answer: c) amiloride
It is a potassium-sparing diuretic (nonaldosterone antagonist)
Where do thiazide diuretics act?
a) distal tubule
b) glomerulus
c) loop of henle
d) collecting tubule
Answer: a) distal tubule
They act in the early segment of the distal convoluted tubule
Which is not an indicated use for thiazide diuretics?
a) HTN
b) diabetes insipidus
c) edema
d) pulmonary edema
Answer: d) pulmonary edema
True or false, potassium-sparing diuretics produce a modest increase in urine production?
True. They work more-so when used in conjunction with another diuretic to decrease K+ loss.
Spironolactone is what type of diuretic?
a) loop
b) thiazide
c) potassium-sparing
d) osmotic
Answer: c) potassium sparing
Which of these are nonaldosterone antagonists?
a) spironolactone
b) triamterene
c) amiloride
d) mannitol
Answer: b & c
Note: spironolactone is an aldosterone antagonist
What is the MOA for spironolactone?
a) blocks action of aldosterone
b) directly inhibits the exchange mechanism for aldosterone
c) creates an osmotic gradient
d) causes vasoconstriction which stimulates aldosterone
Answer: a) blocks action of aldosterone
This will increase the “peeing” out of sodium and the retention of K+ and H+
What is the MOA for triamterene?
a) blocks action of aldosterone
b) directly inhibits the exchange mechanism for aldosterone
c) creates an osmotic gradient
d) causes vasoconstriction which stimulates aldosterone
Answer: b) directly inhibits the exchange mechanism itself
DOES NOT block aldosterone it just blocks the pump
