A nurse is caring for a client with PROM who is receiving magnesium sulfate as a tocolytic agent.
Which of the following assessments should the nurse perform to monitor for magnesium toxicity?
Deep tendon reflexes
Urine output
Serum magnesium level
All of the above.
The Correct Answer is D
The nurse should perform all of the assessments listed to monitor for magnesium toxicity.
Magnesium sulfate is a drug that is given to prevent preterm labor by relaxing the uterine muscle.
However, it can also cause serious side effects such as weakness, low blood pressure, respiratory paralysis, and cardiac problems if the level of magnesium in the blood is too high.
The normal level of magnesium in the blood is about 1.5-2.5 mEq/L. Symptoms of toxicity may appear when the level reaches 4 mEq/L or higher.
