Question 5

Proportionate losses of sodium and water.

a. ) isotonic fluid volume deficit
b. ) isotonic fluid volume excess

Answer 5

a.) isotonic fluid volume deficit

isotonic decrease in extracellular fluid compartment.

Proportionate losses of sodium and water**.

P/C factors:

• impaired fluid intake
  
  • inability to obtain fluids (i.e. decrease in mobility, coma, decreased access)
  • impaired thirst
  • impaired swallowing
• excessive fluid losses
  
  • GI loss (i.i. vomiting, diarrhea, GI suction)
  • Renal loss (i.e. polyuria, diuretic therapy)
  • Skin (i.e. sweating related to fever or exercise, burns)
  • 3^rd spacing

Isotonic expansion of extracellular fluid compartment.

a. ) isotonic fluid volume deficit
b. ) isotonic fluid volume excess

Answer 6

b.) isotonic fluid volume excess

isotonic expansion of extracellular fluid compartment.
