What are the signs and symptoms of hyponatremia?
SALT LOSS, Seizures/Stupor, Abdominal cramping, Lethargic, Trouble concentrating, Low urine output, Orthostatic hypotension, Spasm of muscles, Shallow Respirations
What causes hyponatremia?
fluid overload, liver disease, adrenal insufficiency, low intake, excessive use of diuretics
What are the nursing interventions for hyponatremia?
restrict fluids, consume foods rich in sodium
What are the signs and symptoms of hypernatremia?
fever, fluid retention, restlessness, agitation, orthostatic hypotension, dry mucous membranes, edema
What causes hypernatremia?
hypercortisolism, increases sodium intake, GI feeding, dehydration
What are the nursing interventions for hypernatremia?
restrict sodium intake, patient safety
what IV fluids will be given for hypernatremia?
typically, isotonic, 0.9% saline
what are the average lab values for potassium?
3.5 - 5.0
what causes hypokalemia?
laxatives, diuretics, corticosteroids, heavy liquid loss, inadequate intake, too much water intake, DKA
what are the signs and symptoms of hypokalemia?
Lethargic, low shallow respirations, leg cramps, lethal cardiac changes, limp muscles, low BP and HR
what are the nursing interventions for hypokalemia?
Cardiac assessments, hold lasix, respiratory assessment, respiratory assessment, watch magnesium level
what causes hyperkalemia?
burns, tissue damage, acidosis, excessive potassium intake, adrenal insufficiency, NSAIDs , ace inhibitors
what are the signs and symptoms of hyperkalemia?
muscles weakness, weak pulse, low BP, low urine production, muscle twitching, respiratory and cardiac failure, cardiac rhythym changes
what are the nursing interventions for hyperkalemia?
stop IV potassium infusions/supplements, potassium restrictive diet, kayexelate oral/enema, prepare for dialysis
what IV fluids will be given for hyperkalemia
Hypertonic
Insulin may be given via IV to help potassium absorption
