Kidneys, ureters, bladder, urethra
Name two drugs that are contraindicated in uremic patients
rompum and ketaset
renal damage may be categorized as
Prerenal, renal, postrenal
explain how diuretics work
Diuretics work by removing excess extracellular
fluid, by increasing urine volume and sodium
excretion, and by decreasing hypertension
whats supplements may be administered in conjunction with loop diuretics
Potassium
ACE inhibitors block the conversion of angiotensin 1 to
Angiotensin II
Urinary acidifiers are used to produce acid urine, which assist in dissolving and preventing the formation of _______ uroliths
struvite
the renal cortex produces _______; thus CRF can cause and absolute or relative ______.
Erythropoietin, decrease
why is furosemide referred to as a loop diuretic
Inhibit the tubular reabsorption
of sodium.
It also prevents Na from being reabsorbed at the loop of henle. Causes hypokalemia which causes muscle weakness.
Where is ADH excreted
Posterior pituitary gland
where do the ureters originate from ?
from the kidneys and connect to
the urinary bladder
Persistently high blood pressure is known as

urinary acidifiers are used to produce acid urine, which assist in dissolving and preventing the formation of
uroliths
_________ is the medical term for bloody urine
hematuria
what part of the kidney is responsible for reabsorption, or secretion, of certain substances?
tubules
patients with renal failure are at a lesser anesthetic risk than patients with normal renal function
false
loop diuretic inhibit the tubular reabsorption of ________.
sodium
what are the 2 test performed for kidney fx, which one is more specific
BUN & creatinine (more specific)
what is the byproduct of ammonia that the liver breaks down
urea
explain fluid balance
electrolytes: where Na goes, water goes
fx of the kidney
filter: Proximal convoluted tubule
reabsorb: loop of henle
secrete: distal convoluted tubule
glomerulus works under _____ pressure
high
Puts fluids back to blood where there is an osmotic imbalance
aldosterone
where is erythropoietin formed from
DCT and works on Bowmans to produce RBCs
what types of class is Xylazine
Alpha 2 agonist
what types of class is ketamine
cyclohexamine
used as a disassociative: preanesthetic and as analgesic
describe: pre renal
decreased blood flow to kidneys (dehydration) plasma is decreased
describe: renal
kidneys have lost the ability to filter and something has happened with nephrons (old age)
describe: post renal
