A serum sodium below 135 mEq/L, usually from too much water relative to sodium. Nursing care centers on finding the cause, correcting sodium slowly, and protecting the patient from neurologic harm.

Assessment
- Subjective: patient reports headache, nausea, muscle cramps, confusion, or feeling "foggy"
- Objective: serum Na+ below 135 mEq/L, altered mental status, lethargy, seizures in severe cases, fluid volume status (edema, dry mucosa, or euvolemic)
Nursing diagnoses
Risk factors: Na+ below 135 mEq/L, confusion, lethargy
As evidenced by: serum Na+ low, changes in weight and intake/output
Goals / expected outcomes
- The patient's serum sodium will rise toward normal at a controlled rate (provider commonly limits correction to no more than about 8 mEq/L in 24 hours) with no new neurologic deficits.
- The patient will stay free of injury and seizure-related harm throughout the correction period.
Nursing interventions & rationale
| Intervention | Rationale |
|---|---|
| Correct sodium slowly per orders and monitor the rate of rise with serial Na+ levels. | Raising sodium too fast can cause osmotic demyelination syndrome, a permanent brain injury. |
| Restrict fluids as ordered for euvolemic or hypervolemic hyponatremia. | Limiting free water lets sodium concentration recover when excess water is the cause. |
| Institute seizure precautions and monitor neurologic status frequently. | Severe or rapidly falling sodium can trigger seizures and needs a safe environment. |
| Track intake and output, daily weight, and volume status; give sodium or hypertonic saline only as prescribed. | Accurate balance data guide therapy and prevent over-correction. |
Evaluation
- Serum sodium rises within the ordered, controlled rate
- No seizure activity or injury occurs
- Mental status returns to baseline
