Electrolyte Imbalances Flashcards
What does too much and not enough sodium do?
Too much can cause oedema
Sodium loss Amman lead to hypovolaemia
What are the normal ranges for sodium and what are the ranges for mild, moderate, and severe hypoatrieamia?
Normal: 135 to 145
Mild: 120-130
Moderate: 110 to 120
Severe:
What are the signs and symptoms of hypoatrieamia?
Lethargy, confusion, convulsions, coma, hypotension, tachycardia, oedema, venous distention
What are the symptoms of hypernatreamia?
Thirst Fever Dry mouth Convulsions APO Elevated blood pressure Bounding pulse
What are the 5 main functions of sodium?
Maintain ECF osmolarity
Regulates water distribution and ECF volume
Controls other electrolytes
Combines with other electrolytes to balance acid- base
Impulse transmission I’m nerves and muscles
What is the function of potassium?
To maintain osmolarity of the ICF
What are the normal ranges of potassium? Hyperkaleamia associated with nerve and muscle function
3.5 to 5.5
Causes of hyperkaleamia?
Cell trauma: burns, crush
Supplement overdose
Decreased renal secretion
What are the signs of hyperkaleamia?
Mild: neuromuscular irritability
Peaked T waves
Severe: paralysis
ST depression, long PR, wide QRS, VF
What are causes and symptoms of hypokaleamia?
Alkalosis, increased renal loss ( diuretics)
Decreased muscle tone
Bradycardia
AV block
