MAGNESIUM: 1.3 to 2.1
Magnesium has a Sedative Affect: Therefore, if Magnesium is HIGH > 2.1, then everything is sedated: slow! If Magnesium is LOW
<1.3, then everything has gone WILD! Magnesium is the SHERRIFF in Town! IF there is NO sherriff, all the muscles are WILD and
Hyperactive; when the sherriff is in town, all the muscles calm down!
■Recently recognized as more crucial to body function than some other electrolytes
■ACTIVATOR in many enzyme reactions
– Vitamin B metabolism
■Mg and K levels increase and decrease together
Hypomagnesemia:
■SIGNS AND SYMPTOMS:
–Tremor/excessive neuromuscular irritability
–Choreiform movements
–Tetany/Seizures
–Constipation/ileus
–Ataxia
–Increased reflexes : Increased DTR’s (Deep Tendon Reflexes)
–Clonus
■Treatment:
–Correct the underlying cause
–Encourage foods rich in magnesium: unprocessed cereal, grains, nuts, chocolates, green leafy vegetables, dry beans,
peas (legumes), fruit (bananas), meats, fish, peanut butter
–Administer Magnesium Sulphate: intravenously, intramuscularly, orally (watch for diarrhea), check DTR, antidote is
Calcium Gluconate
Hypermagnesemia:
■SIGNS AND SYMPTOMS:
–Related to depressed CNS
–Serum Mg++ of 3-5 mEq/L
■Hypotention (vasodilation)
■Flushing
■Nausea
■Diminished deep tendon reflexes
■Muscle weakness/cardiac arrest, lethargy
■Decreased Pulse
■Decreased Respiration
■Nausea, vomiting
■Flushing
■Slurred Speech
–Serum Mg++ of > 7 mEq/L
■Deep tendon reflexes absent
■Resiratory depression/arrest
■Coma
■Heart block/cardiac arrest
■Treatment
–Treat cause of the excess
–Stop magnesium sulfate infusion:
■Rest below 12, pulse below 60, urine output < 30 mL/hr
–IV Ca++ gluconate- antagonist effect (initially 7 mEq IV)
–Provide for client safety r/t muscle weakness
■Mg SO4 Toxicity: BURP
–BP decrease
–Urine output decrease
–Respiratory rate decrease
–Patellar reflect absent
