00027 Deficient fluid volume

Definition of the NANDA label

Deficient fluid volume is the state in which there is a decrease in intravascular, interstitial or intracellular fluid, with dehydration or loss of water only and no change in sodium level.

Decreased intravascular, interstitial, and/or intracellular fluid. This refers to dehydration, water loss alone without change in sodium.

The defining characteristics, related factors, NOC and NIC of the NANDA diagnosis “Fluid volume deficiency” are detailed below.

Defining characteristics

  • Decreased diuresis.
  • Increased urine concentration.
  • Sudden weight loss (except in the third space).
  • Hypotension.
  • Decreased venous filling.
  • Increased pulse rate.
  • Decrease in the volume / pressure ratio of the pulse.
  • Decreased turgor of the skin and tongue.
  • Dry skin and mucous membranes.
  • Increase in body temperature.
  • Increased hematocrit.
  • Weakness.
  • Mental confusion.
  • Thirst.

Related factors

  • Active loss of fluid volume.
  • Deterioration and failure of regulatory mechanisms.

At risk population

  • Extremes of age
  • Extremes of weight
  • Factors influencing fluid needs

Associated condition

  • Active fluid volume loss
  • Compromised regulatory mechanism
  • Deviations affecting fluid absorption
  • Deviations affecting fluid intake
  • Excessive fluid loss through normal route – Fluid loss through abnormal route
  • Pharmaceutical agent


  • Electrolyte and acid-base balance.
  • Water balance.
  • Nutritional status: food and fluid intake.
  • Hydration.
  • Neurological state.


  • Acid-base handling.
  • Fluid and electrolyte management.
  • nutritional surveillance and management.
  • Liquid monitoring.
  • Intravenous (IV) therapy.
  • Management of hypovolemia.
  • Neurological monitoring.
  • Monitor vital signs.

This diagnosis will retire from the NANDA-I Taxonomy in the 2021-2023 edition unless additional work is completed to bring it up to a level of evidence 2.1 or higher.
