Fluid Volume Deficit (Dehydration) Nursing Diagnosis & Care Plan

Living with a fluid volume deficit can be an intimidating experience, as you might feel overwhelmed by the intricate aspects of determining your exact needs and devising an appropriate care plan. As a nursing professional, however, understanding this condition is paramount to providing effective patient care.

In this blog post, we’ll discuss the details of Fluid Volume Deficit (FVD) and provide valuable insight into how to best construct an individualized Nursing Care Plan (NCP) for those suffering from FVD. You’ll gain invaluable information on treatments that can help restore balance in patients involving intravascular hydrostatic pressure compensations and other fluids critical for health maintenance.

By utilizing research-based evidence and clinical practice guidelines, we hope to equip healthcare professionals with powerful tools to tackle the complexities associated with fluid volume deficits.

What is Fluid Volume Deficit / Deficiency?

Fluid volume deficit or deficiency, also known as dehydration, occurs when the body loses more fluids than it takes in. This can happen for various reasons, including excessive sweating, diarrhea, vomiting, or simply not drinking enough fluids.

When the body is dehydrated, it can lead to symptoms such as thirst, dry mouth, dizziness, fatigue, and darker urine. Severe dehydration can even cause unconsciousness, seizures, or death. It’s essential to be mindful of your fluid intake and pay attention to any symptoms of dehydration, especially during hot weather or physical activity. Staying adequately hydrated is crucial for maintaining overall health and wellness.

Note- Dehydration and Hypovolemia are two distinct conditions that affect the human body, though they are often confused. Hypovolemia specifically refers to a decrease in blood plasma volume, whereas dehydration encompasses any loss of total water content from the body. As the treatments for these two issues differ, it is essential to recognize their distinction.


One of the body’s primary responses to fluid volume deficit is to reduce intravascular hydrostatic pressure. This is accomplished by lowering plasma osmolality, which causes water to move out of cells and into the bloodstream. Additionally, the heart rate increases to maintain an effective circulatory system and peripheral vascular resistance is decreased. However, this compensation only serves as a temporary measure, and if the fluid volume deficit persists, it can lead to severe complications.


Here are the general factors or etiology for fluid volume deficit:

  • Excessive sweating due to physical activity, environmental temperature, or illness.
  • Diarrhea and vomiting lead to an increased loss of fluids in the body
  • Inadequate intake of fluids due to medical conditions such as dysphagia or inability to drink or chew.
  • Medications that cause excessive urination and fluid loss
  • Medical conditions such as diabetes, kidney or liver disease, or congestive heart failure
  • Age-related factors

Signs and Symptoms

Common signs and symptoms associated with dehydration include:

  • Dry mouth
  • Thirst
  • Headache
  • Fatigue
  • Dizziness
  • Darker urine
  • Decreased perspiration
  • Low blood pressure
  • Rapid heartbeat

Who Is At Risk?

Anyone can become dehydrated, but some specific individuals may be at a higher risk. This includes infants and young children, the elderly, athletes, those with chronic medical conditions such as diabetes or kidney disease, and people taking certain medications.

Nursing Care Plan for Fluid Volume Deficit (Dehydration)

The nursing care plan for fluid volume deficit should include the following objectives:


1. Complete a thorough head-to-toe assessment: By assessing the whole person and putting together all data, the nurse can better make clinical decisions and identify the reason for dehydration.

2. Assess the patient’s skin turgor: This will help to determine how effectively the body is circulating and retaining fluids.

3. Measure the patient’s intake and output of fluids: This will help to identify fluid balance and any additional deficits that need to be addressed.

4. Monitor vital signs: This will provide insight into the patient’s health status.

Fluid Volume Deficit [Dehydration] Nursing Diagnosis:

  • Risk for fluid volume deficit related to inadequate fluid intake.
  • Decrease in perfusion secondary to the reduction in fluid volume.

Nursing Interventions for Fluid Volume Deficit

1. Encourage/remind the patient of the need for oral intake: As individuals age, their thirst may decrease. Reminding and encouraging them to drink fluids even when they don’t feel thirsty is essential to stay hydrated. This will help keep them properly hydrated and healthy.

2. Educate the patient on healthy dietary choices: It is essential to teach them about proper nutrition and how to obtain adequate fluid intake from foods such as fruits, vegetables, and soups high in water.

3. Administer IV fluids if necessary: If oral intake is insufficient to maintain adequate hydration levels, administering IV fluids may be required.

4. Monitor the patient’s electrolyte levels: Dehydration can lead to electrolyte imbalances such as sodium, potassium, and chloride. Monitoring these levels will help ensure the patient stays within a normal range.

5. Monitor urine output: This will help identify if an adequate amount of fluid is being released from the body or if there is a need for additional fluids.

6. Provide emotional support: Many individuals living with dehydration experience feelings of fear and anxiety which can worsen their condition. Providing emotional support can help them healthily cope with these emotions and aid in their recovery process.

7. Evaluate response to treatment: It is essential to assess the patient’s response to treatment to adjust and modify care.

Final Words

Nursing diagnosis for dehydration should focus on restoring the patient’s fluid balance, monitoring electrolyte imbalances, and encouraging healthy dietary choices. Nursing interventions for dehydration include administering IV fluids, monitoring urine output, providing emotional support, and evaluating response to treatment. It is essential to recognize the signs and symptoms of dehydration to prevent any further complications from occurring. With proper hydration and nutrition, you can maintain overall health and wellness.
