What solution/fluids should we use for Normal saline
patients in mild Na deficit?
A patient who has blood loss or Lactated Ringers
diarrhea, can benefit from what type
of fluids?
Approximately 2/3 of body fluid is in Intracellular fluid (ICF)
the _______________________ compartment. Extracellular fluid (ECF)
Approximately 1/3 of body fluid is in
the _______________________ compartment.
Which compartment contains the ECF
intravascular (blood), interstitial, and
trans cellular fluid spaces?
Total body water makes up 60%
approximately how much body
weight?
What are the 3 divisions of ECF? 1. Intravascular space (plasma)
2. Interstitial space (fluid which surrounds cell i.e.
lymph)
3. Transcellular space (CSF, pericardial, synovial,
intraocular, pleural fluids, sweat, and digestive
secretions)
,Third-space fluid accumulates within - ascites
membrane-bound spaces in the body. - pleural effusion
What are examples of third-spacing - pericardial effusion
fluid? - angioedema
What is serum osmolality? A measure of the solute concentration of the blood
(usually sodium, BUN, and glucose)
What is urea? Waste! BUN measures urea
1. Protein is digested
2. turned into ammonia
3. liver turns ammonia to urea for excretion
Will your HCT be higher or lower of Higher
you are dehydrated? *HCT measures percentage of RBCs in whole blood
Will your HCT be higher or lower of Lower
you are overhydrated?
What lab measures muscle breakdown Creatinine
which is excreted by kidneys?
The body does not retain sodium in False. It does. Dehydration causes cells to become
fluid volume deficit. T/F? hypertonic.
What study is best to measure fluid Urine osmolality
status and most indicative of sodium?
What does urine specific gravity Density of urine compared to water. It includes
measure? glucose and protein.
What is the difference between Hypovolemia indicates equal parts of electrolyte and
hypovolemia and dehydration? water loss while dehydration refers to loss of water
alone with increased Na levels.
ADH and aldosterone tell our kidneys hold
to _______ onto water.
, Can ADH deficiency or resistance Hypovolemia
cause hyper- or hypovolemia? * ADH means "anti" + "excessive urine" which means
when we have a defect in ADH, we are urinating
excessively and losing fluid.
What is the #1 sign of hypovolemia? It Weight loss
is also our first intervention. * daily weights every 24hrs at the same time of day
I have: Hypovolemic
- high HCT
- high BUN
- high Na+
- Increased urine specific gravity +
osmolality
Am I hypovolemic or hypervolemic?
How do we medically manage - if not severe, oral hydration preferred
hypovolemia? - isotonic or hypotonic IV (helps excrete metabolic
waste)
What is nursing management of 1. I+O q8h or hourly
hypovolemia? 2. daily weights
3. V/S q4h
4. observe for weak, rapid pulse, and orthostatic
hypo
5. skin turgor and mucus membranes
6. id risk factors (treat the cause)
An acute loss of 0.5kg (1.1lbs) 500mL
represents a fluid loss of how many
mLs?
How much does 1L of fluid weigh? 1kg
