MAGNESIUM Flashcards
Normal mg magnifian level is
1.3 to 2.3 mEq/L
definition of mg
It acts as an activator for many intracellular enzyme systems.
Plays a role in both carbohydrate and protein metabolism
Magnesium balance is important in neuromuscular function.
what is hypomagnesemia
Frequently associated with hypokalemia and hypocalcemia.
causes of hypomagnesemia
alcoholism, GI losses, enteral or parenteral feeding deficient in magnesium, medications, rapid administration of citrated blood
clinical manifestations of hypomagnesemia
Chvostek sign
Trousseau sign
apathy
depressed mood
psychosis
neuromuscular irritability
muscle weakness
tremors
ecg changes and dysthymia
SIGNS OF HYPOCALCEMIA
medical management for hypomagnesemia
• Magnesium sulphate IV is administered with an infusion pump monitor vital signs and urine output
Oral magnesium
nursing management for hypomagnesemia
Vital signs must be assessed frequently during magnesium administration.
Monitoring urine output is essential before, during, and after magnesium administration.
Calcium gluconate must be readily available to treat hypocalcemic tetany or hypermagnesemia.
Monitor for dysphagia
Seizure precautions
Dietary teaching
how can you say that the patient in hypomagnesemia have a mg toxicity
I&O 100ml/4hrs
What is hypermagnesemia
Rare electrolyte abnormality, because the kidneys efficiently excrete magnesium
causes of hypermagnesemia
Causes: kidney injury, diabetic ketoacidosis, excessive administration of magnesium, extensive soft tissue injury
clinical manifestations for hypermagnesemia
Hypoactive reflexes, drowsiness, muscle weakness, depressed respirations, ECG changes, dysrhythmias, and cardiac arrest
medical management for hypermagnesemia
Focus on prevention.
✓ Client with renal failure should not take magnesium containing drugs.
✓ Promote urinary excretion by increasing fluid intake
IV calcium gluconate
Hemodialysis
Administration of loop diuretic, sodium chloride, and LR
nursing management for hypermagnesemia
Monitor the vital signs, noting hypotension and shallow respirations, and check for respiratory depression
Observe for decreased deep tendon reflexes (DTRs) and changes in the level of consciousness.
