Terms
1/3 of the body's water is located in these compartments
What is the extracellular fluid space? (interstitial 25% of the body's water & intravascular space holds the remaining 8%).
136-145 mEq/L
What is serum sodium?
3.0-4.5 mg/dL
What is serum phosphorus?
A shift of fluid into soft tissues
What is peripheral edema?
Best indicator of fluid balance.
What is weight?
2/3's of the body's water is located in this compartment.
What is the intracellular fluid compartment?
98-106 mEq/L
What is serum chloride?
10-20 mg/dL
What is blood urea nitrogen?
A fluid shift into the abdomen.
What is ascites?
The normal range of urine output for an adult patient. (mL/hr)
What is 30-50mL/hr?
Kidneys help maintain homeostatis by filtering the blood and removing cellular wastes and excess fluid through urination.
What is the process of filtration? P.S. review hydrostatic pressure. (Kidneys also return needed water and electrolytes back into circulation).
3.5-5.0 mEq/L
What is serum potassium?
0.5- 1.2 mg/dL
What is creatinine?
A fluid shift into the pleural space.
What is a pleural effusion?
Calculating urinary output on an infant.
What is obtaining the weight of a dry diaper, weighing the soiled diaper then subtracting the weight of the dry diaper? The difference is converted by 1g of weight=1mL of urine.
The ability of solutes to make water move in or out of the cells (or from one compartment to another) via osmosis.
What is tonicity? (includes isotonic, hypotonic and hypertonic solutions).
1.3-2.1 mEq/L
What is serum magnesium?
1.005-1.030
What is urine specific gravity?
Clinical manifestations of fluid volume deficit? Select all that apply.
A. Weight decreased
B. Increased heart rate
C. Jugular vein distention
D. Increased blood pressure
E. Decreased urine output
F. Increased urine specific gravity
What is......
A. Weight decreased
B. Increased heart rate
E. Decreased urine output
D. Increased urine specific gravity (more concentrated; > 1.030)
Clinical manifestations of hypervolemia.
A. Bradycardia
B. S3 heart sound
C. Postural hypotension
D. Decreased skin turgor
What is.....
B. S3 heart sound
Occurs when fluid leaves the vascular space and enters the space between cells, becoming unavailable to support normal physiological activities.
What is third spacing? (often r/t decrease in oncotic pressure, fluid will shift creating-ascites, pleural effusions, peripheral edema, burns).
9.2-10.5 mg/dL
What is serum total serum calcium?
Female:37-47 g/dL
Male:42-52 g/dL
What is hematocrit (females,male)?

A. Weight increase
B. Decreased heart rate
C. Jugular vein distention
D. Edema
E. Decreased blood pressure
F. Clear lung sounds
G. Decreased urine specific gravity
What is......?
A. Weight increase
C. Jugular vein distention
D. Edema
G. Decreased urine specific gravity
Laboratory findings with dehydration. Select all that apply.
A. Increased urine specific gravity
B. Deceased serum BUN
C. Decreased serum osmolarity
D. Increased serum osmolarity
E. Increased hematocrit
What is......
A. Increased urine specific gravity (>1.030)
D: Increased serum osmolarity (> 295 mOsm/kg)
E. Hematocrit (increased in both hypovolemia & dehydration unless FVD is r/t hemorrhage)
