RNSG-1105 MODULE 10 MEASURING WEIGHT AND FLUID
INTAKE AND OUTPUT, URINE ELIMATION
______________
* Daily weighs are an important indicator of fluid status
* A kg of weight gained or loss is= to a liter of fluid gained or loss
* IF the amount of fluid gained is more than loss then the PT is at risk for fluid and electrolyte
imbalance - Correct Answer Fluid status
What is the single most important indicator of fluid status in a PT? Explain - Correct Answer Daily
weights are the most important indicator because fluid gains and loses indicate changes in the
amount of total body fluid
How many kg of weight gained or loss is equal to liters gained or loss?Calibrated measuring
containers - Correct Answer 1 kg= 1 L
What conditions would warrant the need for measuring a PTs daily weigh and compare with intake
and output? - Correct Answer *pre/Pst operative
*NPO
*Severe trauma/burns
*PT taking diuretics
*Dependent on others nutritional needs
*Special drainage
*Nasogastric suction
What guidelines are used in obtaining daily weights? - Correct Answer *PT should be weighed at the
same time, on the same equipment and with the same clothes on
*PT is weighed in the early AM
*HCP may order to assess fluid gain/loss and not for nutritional purposes
*PT height is obtained only upon admission to hospital (No shoes on)
What devices are used in measuring daily weighs and rationale for use? - Correct Answer *Scale
(Ambulatory PT)
*Chair scale (PT can sit)
, *Bed Scale (non mobile PT)
What devices are used in measure intake and output? - Correct Answer Calibrated measuring
containers
How would you measure I&O w/ diaper wet w/urine? - Correct Answer * weigh it (1g = Ml of urine)
How would you measure I&O with a soiled sheet? - Correct Answer Estimate (sm, md, lg)
What types of items are calculated as intake? as output? - Correct Answer -(Input)- oral fluids, ice
chips, food that is liquid at rm temp, tube feedings, parenteral fluids, GU irrigation
-(output) urine, vomit, liquid feces, tube drainage, wound drainage
When is an intake and output worksheet used? - Correct Answer Anytime a fluid enters or exits the
body
What is documented on the intake and output flowsheet? - Correct Answer -time
-amount of fluid
(totals are added at the end of 24hr period)
_________
-surrounds all the cells in the body and is also inside the cells
-means water that contains dissolved or suspended substances such as glucose, mineral salts, and
proteins - Correct Answer Fluid
Fluid, electrolyte, and acid-base balances w/i characteristics of body fluid influence the ________
system - Correct Answer body
__________ is the substantial proportion of the body weight - Correct Answer water
Body fluids are located in 2 distinct compartments:
____________outside the cells
__________inside the cells - Correct Answer Extracellular Fluid (ECF)
