fluid volume imbalances - CORRECT ANSWER - hypovolemia
hypervolemia
hypovolemia - CORRECT ANSWER - fluid volume DEFICIT
(dehydration)
hypervolemia - CORRECT ANSWER - fluid volume excess
_____ has a higher percentage of water content compared to _____ -
CORRECT ANSWER - lean body mass;
fat
who has lower levels of lean body mass? - CORRECT ANSWER - women
(comparatively to men)
older adults
why are older adults at higher risk for fluid-related problems compared to
younger adults? - CORRECT ANSWER - less lean body mass = lower water
content
main ECF cation - CORRECT ANSWER - sodium
,main ECF anion - CORRECT ANSWER - chloride
main ICF cation - CORRECT ANSWER - potassium
main ICF anion - CORRECT ANSWER - phosphate
what nursing intervention is used for monitoring fluid volume? - CORRECT
ANSWER - daily weights
(daily weights are the most sensitive indicator of fluid volume status)
how should daily weights be taken? - CORRECT ANSWER - same time
(morning after using restroom)
same amount of clothing
same scale

what labs monitor fluid volume? - CORRECT ANSWER - hematocrit
BUN
creatinine
sodium
normal hematocrit - CORRECT ANSWER - men: 42-52%
women: 37-47%
normal BUN - CORRECT ANSWER - 10-20 mg/dL
normal creatinine - CORRECT ANSWER - 0.6-1.2 mg/dL
normal sodium - CORRECT ANSWER - 135-145 mEq/L
what other labs can indicate a fluid volume imbalance? - CORRECT
ANSWER - plasma osmolality
urine specific gravity
, osmolality - CORRECT ANSWER - measures the concentration of molecules
per weight of water
plasma osmolality can indicate the state of the body's.... - CORRECT
ANSWER - water balance
plasma osmolality = - CORRECT ANSWER - (2 x Na) + (BUN/2.8) +
(glucose/18)
normal plasma osmolality - CORRECT ANSWER - 280-295 mOsm/kg
plasma osmolality >295 mOsm/kg = - CORRECT ANSWER - WATER
DEFICIT
(the solute concentration is too high and the water content is too low)
plasma osmolality <274 mOsm/kg = - CORRECT ANSWER - WATER
EXCESS
(the solute concentration is too low for the given water content OR the water
content is too high)
urine specific gravity - CORRECT ANSWER - measures the osmolality of
urine
concentrated urine has a urine specific gravity... - CORRECT ANSWER -
>1.025
concentrated urine = _____ = _____ - CORRECT ANSWER - elevated urine
specific gravity;
