Fluid/Electrolyte/Acid-Base Balance Flashcards
Hyponatremia
Fluid and dietary management
Fluids and foods high in sodium
Fluids are often restricted if pt has fluid overload
What are the main priorities for someone with hyponatremia?
Restoring sodium and water balance;
Preventing cerebral edema
NANDA Diagnoses for patient with Hyponatremia
Risk for: Imbalanced fluid volume, ineffective cerebral tissue perfusion
Serum sodium level for patient with hypernatremia
Greater than 145 mEq/L
Cause of Hypernatremia
Excessive water loss
Excessive sodium intake
Manifestations of patient with hypernatremia
Thirst,
Altered neurologic function
Can progress to seizures, coma, and death
Diagnosis of hypernatremia
Serum sodium and osmolality
Medications to treat hypernatremia
Oral, enteral, or IV fluid replacement
Normal Level
Potassium
3.5-5.3 mEq/L
Functions of Potassium
Nerve Impulses;
Cardiac Rhythms;
Muscle contractions
What does potassium regulate
Sodium-potassium pump
Kidneys and aldosterone
Hypokalemia
Definition
Low serum potassium
Serum potassium level
Hypokalemia
Less than 3.5 mEq/L
Manifestations of Hypokalemia
Nausea & Vomiting;
Muscle weakness;
Cramps; Decreased cardiac output;
Polyuria
