Question

A nurse is assisting with collecting data for a client who is in preterm labor and is receiving magnesium sulfate via continuous IV infusion. Which of the following findings should the nurse identify as an indication of magnesium toxicity?

a. Urinary output 60 mL/hr
b. Hyporeflexia
c. Respirations 16/min
d. Tachycardia

Answer 1

Hyporeflexia is an indication of magnesium toxicity in a client receiving magnesium sulfate via continuous IV infusion for preterm labor, which nurses should monitor for.

Step-by-step explanation:

The nurse should identify hyporeflexia as an indication of magnesium toxicity. In a client who is receiving magnesium sulfate via continuous IV infusion for preterm labor, signs of magnesium toxicity include decreased or absent deep tendon reflexes, urinary output less than 30 mL/hr, respiratory depression (less than 12 breaths per minute), and bradycardia rather than tachycardia. It is important for the nurse to carefully monitor these vital signs and reflexes to prevent and quickly address magnesium toxicity.
