small intestine

the term ‘occult blood’ describes blood that

is hidden and not visibly apparent in the stool specimen

what is the most significant sperm analysis result that may indicate an infection in the male genital tract

leukocytes in semen

the function of the large intestine is primarily to

absorb water, sodium, and chloride

an increased number of meat fibers (creatorrhea) in feces correlates with

impaired digestion

vitality assessment of a semen specimen includes evaluation of

percentage of living sperm

a sperm motility graded as 3 indicates

motile with moderate linear progression

approximately 70% of the ejaculate fluid comes from the

seminal vesicles

neutral fats can be viewed microscopically for qualitative fat analysis by staining with the following EXCEPT

methylene blue

the sugar (carbohydrate) of interest in male fertility is

fructose

quantitative testing for any fecal substances requires which fecal specimens

multiple day collection

maldigestion

secretory diarrhea can result from all of the following except

the consistency of a fecal specimen can be graded as all of the following except

solid

foul smelling odor from stool can be as a result of

fecal fat

secretory diarrhea caused by

intestinal mucosal damage, drugs, or hormones

osmotic diarrhea caused by

maldigestion, malabsorption

osmolality of feces between 10 and 20 mOsm/kg indicates

secretory diarrhea

osmolality of feces greater than 20 mOsm/kg indicates

osmotic diarrhea

what is steatorrhea

fecal fat excretion exceeds 6 grams/day

when testing for fecal fat, if the first slide has an increased amount of fat, this indicates

maldigestion

when testing for fecal fat, if the second slide has an increased amount of fat, this indicates

malabsorption

which indicator is used to test for occult blood

guaiac

what is occult blood

hidden blood, earliest symptom of colorectal cancer

the first slide for testing fecal fat contains

two drops of 95% ethanol + stain

the second slide for testing fecal fat contains
