A nurse is reviewing laboratory results and discovers a magnesium level of 3.5 mg/dL. The patient complains of muscle weakness and paralysis. The patient has been receiving magnesium sulfate intravenously
The nurse should immediately prepare to administer which of the following medications?
a. Potassium phosphate
b. Magnesium chloride
c. Calcium gluconate
d. Bicarbonate
ANS: C
The neuromuscular blocking actions of magnesium sulfate can be counteracted with the administration of calcium gluconate. When parenteral magnesium is being administered, an injectable form of calcium, calcium gluconate, should be immediately available.
Potassium phosphate, magnesium chloride, and bicarbonate would not help counter the effects of magnesium toxicity.
