microscopy questions

approx. how many nephrons are found in an average kidney

1.3 million

ultrafiltration of plasma occurs in the glomeruli located in the

cortex

which part of the nephron is locate exclusively in the renal medulla

loop of henle

more than 66% of filtered water, sodium, and chloride and 100% filtered glucose, amino acids and proteins are reabsorbed in the

proximal tubulesw

water reabsorption occurs throughout the nephron exxcept in the

ascending loop of henle

the final concentration of the urine is determined within the

collecting duct

oxidation of bilirubin to biliverdin in urine results in which color

green

urine reagent strip should be stored in

cool dry area

a deficiency in arginine vasopressin is associated with a

low specific gravity

milky urine from a 24 year old woman would most likely contain

many white blood cells

when performing a routine urinalysis, the scintists notes a 2+ protein result. the sientist should

confirm with acid precipitation test

which of the following can give false negative urine protein reading

very diluted urine

the ova of which parasite is liekly to be found in urine sediments

trichomonas vaginalis

all require confirmatory tests except

urobilinogen

urine normal color is derived from all except

bilirubin

a brown or black pigment in urine can be caused by

melanin

what test is least affected by standing or improperly stored urine

protein

urine production of less than 400 ml/day is

oliguria

what does ADH/AVP cause

kidneys retain water by increasing reabsorption, producing more concentrated urine

what does aldosterone cause

stimulates reabsorption of Na (water follows) and secretion of K+ and H+
