Explain the relationship between As sodium increases, water decreases, and vice
sodium and water versa.
What are the main functions of - Maintaining acid-base and water balance
sodium? - Muscle and nerve impulses
What are the priority assessments 1. Neurological
with sodium imbalances? 2. Seizure risk
3. I&O
What should ALWAYS be checked Blood glucose
when acute confusion presents?
What is the main cause of Water loss (dehydration) or sodium gain
hypernatremia? (hypertonic saline).
What is the primary preventor Thirst
against hypernatremia?
What is the first indicator of Decreased urine output (<30mL/hr)
hypernatremia?
, How is hypernatremia managed? - Isotonic IV fluids
- Managing the underlying cause (DKA)
Why are isotonic fluids preferred for Often water is low, causing sodium to be high.
hypernatremia? Isotonic fluids replace water that was lost to create
balance and kidney perfusion.
What is the most common cause of Water excess (dilutional hyponatremia) or loss of
hyponatremia? sodium-containing fluids.
What is the priority intervention for Fluid restrictions
hyponatremia caused from excess
fluid?
What causes dilutional - Excess ADH d/t stress or pain
hyponatremia? - Heart, liver, or kidney failure
- Excess water intake
How does ADH cause It reabsorbs water only, not sodium.
hyponatremia?
How is hyponatremia managed? - Fluid restriction
- Hypertonic solutions
When is 3% NaCl given for severe If the patient is symptomatic and sodium is below
hyponatremia? 120mmol/L.
What are complications of - Seizures
hypernatremia, hyponatremia, or - Coma
rapid sodium overcorrection? - Death
