A nurse is caring for a client in preterm labor who is receiving magnesium sulfate by continuous IV infusion. Which of the following client findings indicates medication toxicity?

  • A. Blood glucose of 150 mg/dL
  • B. Urine output of 20 mL per hour
  • C. Systolic blood pressure of 140 mm Hg
  • D. BUN 20 mg/dL
Correct Answer: B

Rationale: A urine output of 20 mL per hour is low and indicates renal insufficiency, a sign of magnesium sulfate toxicity. The medication is excreted by the kidneys, so toxicity can occur if renal function declines. Blood glucose of 150 mg/dL is within normal range and not indicative of magnesium sulfate toxicity. A systolic blood pressure of 140 mm Hg is elevated but not specifically related to magnesium sulfate toxicity. A BUN level of 20 mg/dL is also within normal limits and not a sign of medication toxicity.
