Nursing Care Plan for Dehydration

Dehydration

Definition

Dehydration is a condition in which a person who is not fasting experiencing or at risk of dehydration vascular, interstitial or intra-vascular (Sell Lynda Carpenito, 2000: 139).

Classification

Classification of dehydration by Donna D. Ignatavicus there are 3 types:

a. Isotonic dehydration
Isotonic dehydration is lost water followed by the electrolyte so that the density remained normal, then this type of dehydration is usually not result in ECF fluid move to the ICF.

b. Hypotonic dehydration
Hypotonic dehydration is the loss of solvent from the ECF exceeds fluid loss, resulting in blood vessels become more concentrated. ECF osmotic pressure decreases, resulting in fluid moves from the ECF to ICF. Vascular volume also decreased, as well as cell swelling occurs.

c. Hypertonic dehydration
Hypertonic dehydration is ECF fluid loss exceeds the solvent is non-osmotic dehydration ECF decreased, resulting in fluid moves from ICF to ECF.


Etiology

Various causes dehydration determine the types of dehydration (According to Donna D. Ignatavicus, 1991: 253).

1. Dehydration

• Bleeding.
• Vomiting.
• Diarrhea.
• Hypersalivation.
• Fistula.
• Ileustomy (cutting intestine).
• Diaporesis (excessive sweating).
• Burns.
• Fasting.
• Hypotonic therapy.
• Suction gastrointestinal (stomach wash).

2. Hypotonic Dehydration

• DM disease.
• Excess fluid rehydration.
• Severe and chronic malnutrition.

3. Hypertonic Dehydration

• Hyperventilation.
• Diarrhea water.
• Diabetes Insipedus (ADH hormone decreases).
• Excessive fluid rehydration.
• Dysphagia.
• Impaired thirst.
• Disorders of consciousness.
• Systemic infection: increased body temperature.

Clinical Manifestations

Here are the symptoms or signs of dehydration based on its level (Nelson, 2000):
1. Mild dehydration (loss of fluid 2-5% of its original weight)

• Thirsty, restless.
• Pulse rate 90 -110 x / minute, normal breath.
• Normal skin turgor.
• Urine output (1300 ml / day).
• Good awareness.
• Heart rate increased.

2. Moderate Dehydration (loss of fluid 5% of its original weight)

• Increased thirst.
• Rapid and weak pulse.
• Dry skin turgor, dry mucous membranes.
• Reduced urine output.
• Increased body temperature.

3. Severe dehydration (loss of fluids 8% of its original weight)

• Loss of consciousness.
• Weak, lethargic.
• Tachycardia.
• Sunken eyes.
• No urine output.
• Hypotension.
• Rapid pulse and smooth.
• Cold extremities.
