Dehydration Nursing Care Plan
Definition: Dehydration is a fluid imbalance resulting from insufficient intake, excessive loss, or abnormal fluid distribution, leading to decreased total body water and electrolyte disturbances. Common in older adults, infants, patients with fever, vomiting, diarrhea, diuretic use, or impaired thirst response.
Assessment
History: recent vomiting, diarrhea, fever, decreased oral intake, diuretics, diabetes, cognitive impairment, dysphagia, bleeding, burns.
Vital signs: hypotension, tachycardia, orthostatic changes, fever.
Respiratory: tachypnea if severe.
Skin and mucous membranes: dry mucous membranes, reduced skin turgor, decreased capillary refill.
Neurologic: confusion, irritability, lethargy, decreased urine output, dizziness.
Renal: oliguria (<0.5 mL/kg/hr), concentrated urine (high specific gravity).
Weight: acute weight loss.
Labs: elevated BUN-to-creatinine ratio, increased hematocrit, hypernatremia or hyponatremia depending on type, possible acid-base changes.
Intake/output: quantify deficits and ongoing losses.
Other: lab abnormalities (electrolytes), ECG changes with severe electrolyte disturbance.
Nursing Diagnoses (examples)
Deficient Fluid Volume related to decreased fluid intake and/or excessive fluid losses.
Risk for Electrolyte Imbalance related to fluid loss and replacement therapy.
Risk for Injury related to orthostatic hypotension and dizziness.
Imbalanced Nutrition: Less Than Body Requirements related to decreased oral intake.
Impaired Oral Mucous Membranes related to dehydration.
Goals/Outcomes (SMART)
Patient will demonstrate stable vital signs within age-appropriate range within 24–48 hours.
Patient will maintain adequate urine output (≥0.5 mL/kg/hr or appropriate adult target) within 24 hours.
Patient will show normalization of laboratory values (serum sodium, BUN/Cr) within 48–72 hours.
Patient will report decreased thirst and improved energy level within 48 hours.
Patient will demonstrate knowledge of hydration measures before discharge.
Nursing Interventions and Rationales
Monitor vital signs frequently (including orthostatic checks).
Rationale: Detect hemodynamic instability early (tachycardia, hypotension) and assess response to fluid therapy.
Strict intake and output measurement; weigh daily at same time with same scale and clothing.
Rationale: Quantifies fluid deficit and fluid gains; weight change is sensitive indicator of fluid status.
Assess skin turgor, mucous membranes, capillary refill, and urine output & specific gravity.
Rationale: Physical signs corroborate dehydration severity and help track improvement.
Initiate and maintain prescribed oral or IV fluid replacement per provider orders (oral rehydration solutions for mild-moderate; isotonic IV fluids like 0.9% NaCl for hypovolemic, adjust as ordered).
Rationale: Restore intravascular volume, correct electrolyte imbalances, and prevent complications. Use isotonic fluids to expand intravascular compartment safely.
Administer electrolytes as ordered; monitor serum electrolytes closely.
Rationale: Fluid therapy can alter electrolyte balance; replacement may be necessary to correct sodium, potassium, etc.
Encourage small, frequent sips of fluid if oral intake limited; offer preferred beverages and oral rehydration solutions.
Rationale: Improves fluid intake tolerance and replaces lost electrolytes; patient preference increases adherence.
Treat underlying causes (antiemetics for vomiting, antidiarrheals when appropriate, fever control with acetaminophen and cooling measures).
Rationale: Stopping ongoing losses is essential for rehydration to be effective.
Implement safety measures for orthostatic hypotension (assist with ambulation, sitting up slowly, use of call light).
Rationale: Reduces fall risk related to dizziness and lightheadedness during rehydration.
Monitor for signs of fluid overload when replacing fluids (bounding pulses, crackles, peripheral edema, weight gain).
Rationale: Rapid or excessive fluid replacement, especially in elderly or those with cardiac/renal disease, can precipitate pulmonary edema or congestive heart failure.
Provide oral care: lubricants for lips, mouth rinses, brushing teeth regularly.
Rationale: Improves comfort and decreases risk of mucosal breakdown from dryness.
Education: instruct patient/caregiver about signs of dehydration, importance of regular fluid intake, managing fluid during illness (sick-day plan), medication effects (diuretics), and when to seek care.
Rationale: Prevents recurrence
