Re-absorption Most significant regulator of urine composition
Water Moves passively following osmotic gradient
Solutes Filtered then re-absorbed by active transport
Filtration is non selective
Active tubular secretion Uses pumps selective for organic acids and organic bases for active transport...
180,000ml ✅The kidney produces approximately this many ml of filtrate per day
1800ml ✅The normal amount of urine excreted in 24 hours
Thick segment of the ascending loop of Henle ✅Diuretics that produce the most
significant diuresis affect re-absorption here
Water ✅Antidiuretic hormone affects kidney reabsorption of which substance?
Bumex ✅A patient in chronic renal failure has been retaining fluid despite dialysis.
Which diuretic would the nurse expect to administer?
Clear lung sounds ✅A patient with left sided HF has been prescribed a high ceiling
diuretic. Which assessment most accurately reflects a therapeutic effect of this drug?
Muscle weakness and constipation ✅A patient has been prescribed furosemide. It is a
priority for the nurse to monitor for which symptom that suggests possible excessive
loss of potassium?
Ibuprofen ✅Which over the counter medication can counteract the effects of diuretics?
Thiazide ✅What is the recommended diuretic for initial therapy of essential
hypertension?
, Tinnitus ✅Which symptoms suggest ototoxicity when a patient has been prescribed a
high ceiling diuretic?
Muscle weakness and tremor ✅Shich new symptom suggests hypomagnesemia when
a patient is prescribed a thiazide or high ceiling diuretic?
Angiotensin-converting enzyme (kinase II) ✅Catalyzes the conversion of angiotensin I
into angiotensin II
ACE Inhibitor (Angiotensin converting enzyme) ✅Drug that dilates blood vessels by
decreasing level of angiotensin II formation from angiotensin I, increasing renal
excretion of sodium and water, slightly decreasing heart remodeling, and causing dry
cough by increaasing bradykinin levels.
DRI ✅Drug that acts on renin to inhibit the conversion of angiotensinogen into
angiotensin I suppressing the renin-angiotensin-aldosterone system (RAAS)
ARB (Angiotensin II receptor Blocker) ✅Drug that blocks the action of angiotensin II
causing dilation of blood vessels and potassium sparing diuresis, but does not cause
cough or prevent myocardial remodeling.
Aldosterone receptor antagonist ✅Drug that produces selective blockade of
aldosterone receptors causing potassium sparing diuresis and significant prevention of
myocardial remodeling.
Aldosterone ✅Hormone that causes retention of sodium and water and retention of
potassium and hydrogen by the kidneys to maintain adequate filtering pressure in the
glomerulus.
Renin ✅Secreted by kidney, regulates angiotensin II formation
RAAS ✅System where renin is released from kidneys, resulting in aldosterone release
from adrenals.
Angiotensin II ✅Vasoconstricts and stimulates aldosterone release.
-sartan ✅The nurse recognizes that the generic names of ARB drugs end in which
suffix?
-pril ✅The nurse recognizes that the generic names of ACE inhibitor drugs end in
which suffix?
Hypernatremia ✅What would not stimulate renin release by the kidneys?
