Fluid Balance: Types of Dehydration

Question 1

Extracellular Fluid Volume Deficit: 2 compartments

Answer 1

Not enough fluid in extracellular compartments:

1. **Vascular **
2. Interstitial​

Question 2

Isotonic dehydration or isonatremic dehydration (3)

Answer 2

1. Occurs when fluid loss is not balanced by intake, water and Na loss are proportional.
2. Serum Na within Normal limits/slightly lower
3. Blood vol is lowered

Question 3

Hypotonic dehydration or hyponatremic dehydration

1. __?__loss is greater than __?__loss
2. Compensatory fluid shift between__?__ to __?__
3. Hypotonic dehydration or hyponatremic dehydration is caused by (5)

Answer 3

1. Na loss is greater than water loss
2. Compensatory fluid shift between extracellular to intracellular
3. Can be caused by
   
   1. prolonged vomiting,
   2. diarrhea,
   3. burns,
   4. renal disease,
   5. IV fluid without electrolytes

Question 4

Hypertonic dehydration or hypernatremic dehydration

Hypertonic dehydration or hypernatremic dehydration. __?__loss is greater than Na loss. Compensatory fluid shifts between___?___ to ___?___.

___?___component remains fairly ___?___resulting in ___?___onset of s/s until condition becomes ___?___ e.g. ___?___symptoms
May be caused by ___?___.

Answer 4

Hypertonic dehydration or hypernatremic dehydration. Water loss is greater than Na loss. Compensatory fluid shifts between intracellular to extracellular. Extracellular component remains fairly normal resulting in delaying onset of s/s until condition becomes serious. e.g. Neurologic symptoms
May be caused by diabetes Insipidus
