URINALYSIS - MLT 106 QUIZ WITH COMPLETE
QUESTIONS AND VERIFIED ANSWERS [
GRADED A+]
urinalysis - ✔✔physical, chemical, and microscopic analysis of urine
purposes or urinalysis disease - ✔✔diagnosis, monitor wellness, monitor therapy
nephron - ✔✔functional unit of the kidney where urine is formed
function of kidneys- ✔✔ removal of waste products, retention of nutrients,
acid/base balance, water/electrolyte balance, hormone synthesis
types of urinary epithelial cells- ✔✔ renal (from kidney/nephron - should not be
seen in UA), transitional (from bladder), squamous (seen if dirty urine)
stability for which urine can be kept refrigerated for UA- ✔✔6-8 hours
first morning specimen - ✔✔most concentrated urine; best for HCG test
, 24 hour urine - ✔✔used for chemical assays for diurnal variation
midstream clean-catch - ✔✔specimen of choice for bacterial culture in routine
circumstances
hydrochloric acid, boric acid, or acetic acid - ✔✔common chemical preservatives
for urine
polyuria - ✔✔consistent elimination of abnormally large volumes of urine (>2000
mL/24hours)
diuresis - ✔✔any increase in urine volume
anuria - ✔✔complete absence of urine formation
nocturia - ✔✔excretion of >400 mL of urine at night
oliguria - ✔✔excretion of abnormally small amount of urine (<500 mL/24 hours)
specific gravity - ✔✔the density of urine sample divided by the density of water;
provides info on renal function and hydration state (low value=good kidney/well
hydrated); can be measured via refractometer
dark, dry environment - ✔✔how to store urine dipstick reagent strips
methyl red and bromethymol blue - ✔✔double-indicator pH system
