A family member of a client with severe dehydration asks the nurse, "What are the common causes of dehydration?" The nurse appropriately answers by explaining:

"Severe vomiting."
"Use of diuretics."


• The common causes of dehydration are: unmonitored use of diuretics, severe vomiting, and diarrhea.

• Volume depletion can be produced by the loss of interstitial and intravascular fluid into a third-space (tissue, organ, fracture, etc.).  It is not a common cause of dehydration.

• When lymphatic channels are obstructed or have been removed or damaged, tissue oncotic pressure increases and leads to edema.

• Addison's disease or adrenal crisis is one of the potential causes of fluid loss but not a common cause of dehydration .
