ANSWERS | ALREADY GRADED A+ | LATEST UPDATE




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


weight gain should be reported if... - CORRECT ANSWER - >2 lbs in one day


>5 lbs in one week


1 L of fluid = ____ lbs = ____ kg = ____ mL = ____ IV bag - CORRECT
ANSWER - 2.2;

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;
