Hyponatremia

Question 1

Hyponatremia

Answer 1

Low Na+, low sodium in blood
Water/fluid, brain/nervous
Helps regulate water outside the cell
Range is 135-145
- caused by osmosis- low to high concentration
- causes cell to swell, so sodium and water follow each other

Question 2

Hyponatremia

Answer 2

Common causes “no na”

• N: Na+ excretion increased with renal problems, NG suction, vomiting, diuretics,
• O: overload of fluids (CHF,hypotonic fluids,liver failure)
• N: Na+ intake low
• A: antidiuretic hormone over secreted- adrenal insufficiency
• syndrome of inappropriate of ADH: a condition in which high level of a hormone cause the body to retain water so too much water

Question 3

Hyponatremia s/s

Answer 3

“SALT LOSS”

• S: seizures
• A: abdominal cramping, attitude changes(confusion)
• L: Lethargy
• T: tendon reflexes
• L: loss of urine and appetite
• O: orthostatic hypertension, overactive bowel sounds
• S: shallow respirations
• S: spams of muscles

Question 4

Nursing interventions

Answer 4

• watch cardiac, respiratory, neuro, renal and GI
• monitor sodium level
• 3% saline-hypertonic, shrinks cells down because before cell was swollen
• increase oral sodium intake
