Signs of Volume Overload
Nursing Interventions and Rationales
Monitor I & O, daily weights
Patients may be on fluid restrictions to help balance intake and output. Monitor for retention through calculated intake and output and with daily weights at the same time on the same scale each day.
Continuous ECG monitoring
Changes in electrolyte balance can disrupt the electrical conduction in the heart causing dysrhythmias.
Assess and monitor vital signs every 1-2 hours
Fluid shifts can occur quickly causing changes in blood pressure and heart rate. Most often patients will experience hypotension.
Assess and monitor respiratory status; note changes in respiration, auscultate lungs
Excess fluid volume can settle in and around the lungs and heart. Monitor for signs of congestion, difficulty breathing. SIADH can also be triggered by pneumonia, so monitor for the underlying cause as well.
Administer medication and electrolyte supplements appropriately
Electrolyte supplements (potassium)
Demeclocycline or lithium – stops the kidneys from responding to extra ADH
Supplements may be given to regulate electrolyte imbalance. Carefully administer supplements to avoid overloading too quickly
Monitor lab / diagnostic values
Serum potassium
Serum sodium
Serum chloride
Serum osmolality (concentration)
Urine specific gravity
Hyponatremia is the hallmark of SIADH. Monitor lab values to determine if treatment is effective.
