A serum sodium above 145 mEq/L, usually from water loss or poor water intake. Nursing care focuses on restoring water balance slowly and watching for neurologic changes.

Assessment
- Subjective: patient reports intense thirst, weakness, or restlessness (if alert enough to report)
- Objective: serum Na+ above 145 mEq/L, dry mucous membranes, altered mental status, lethargy or irritability, low urine output, poor skin turgor
Nursing diagnoses
As evidenced by: Na+ above 145 mEq/L, dry mucosa, thirst, decreased urine output
Risk factors: altered mental status, lethargy, high serum sodium
Goals / expected outcomes
- The patient's serum sodium will fall toward normal at a controlled rate (providers commonly limit the drop to about 10 mEq/L per 24 hours) with no new neurologic deficits.
- The patient will show restored hydration (moist mucosa, adequate urine output, stable mentation) as sodium normalizes.
Nursing interventions & rationale
| Intervention | Rationale |
|---|---|
| Replace water and give fluids per orders at a controlled rate, monitoring serial Na+ levels. | Lowering sodium too fast pulls water into brain cells and can cause cerebral edema. |
| Monitor neurologic status, level of consciousness, and for signs of worsening. | The brain is most vulnerable to both high sodium and rapid correction. |
| Track intake and output, daily weight, and thirst; offer water within any swallow precautions. | Balance data confirm the deficit is closing and guide fluid orders. |
| Identify and treat the cause (fever, diarrhea, diabetes insipidus, limited access to water). | Correcting the source prevents the sodium from climbing again. |
Evaluation
- Serum sodium falls within the ordered, controlled rate
- Mucous membranes moist and urine output adequate
- No new neurologic deficits appear

What is the nursing diagnosis for Hypernatremia?
Common nursing diagnoses include: Fluid volume deficit related to water loss exceeding intake; Risk for injury related to neurologic changes from elevated sodium. Choose the one your patient's assessment data supports.
