(Dehydration) - Coggle Diagram
Dehydration
Manifested By
Tachycardia
Compensatory mechanism to maintain cardiac output
Hypotension
Reduced circulating volume
Pale, cool, clammy skin
Peripheral vasoconstriction
Shunting blood to vital organs
Shortness of breath
Increased oxygen demand
Compensatory response to poor tissue oxygenation
Altered level of consciousness
Reduced cerebral perfusion
Reduced oxygen delivery to the brain
Decreased urine output
Reduced renal perfusion
Dry mucous membranes
Thirst
Nursing Interventions
Administer IV fluids as ordered
Encourage oral fluids if appropriate
Apply oxygen if indicated
Monitor oxygen saturation
Position for comfort and ease of breathing
Monitor laboratory values
Electrolytes
BUN
Creatinine
Reassess hydration status frequently
Expected Outcomes
Improved hydration
Stable blood pressure
Heart rate within normal limits
Adequate urine output
SpO₂ maintained at target range
Improved LOC
Reduced shortness of breath
