A client at 30 weeks' gestation is receiving magnesium sulfate for preterm labor. What assessment finding indicates magnesium toxicity?

  • A. Deep tendon reflexes +3.
  • B. Respiratory rate of 10 breaths per minute.
  • C. Urine output of 40 mL/hour.
  • D. Blood pressure of 120/80 mmHg.
Correct Answer: B

Rationale: The correct answer is B: Respiratory rate of 10 breaths per minute. Magnesium sulfate toxicity can lead to respiratory depression, resulting in a decreased respiratory rate. This is a critical sign of magnesium toxicity and should be addressed promptly.

Explanation for other choices:
A: Deep tendon reflexes +3 are actually a common finding in clients receiving magnesium sulfate due to its muscle relaxant effects.
C: Urine output of 40 mL/hour is within the normal range and does not indicate magnesium toxicity.
D: Blood pressure of 120/80 mmHg is also within the normal range and is not a sign of magnesium toxicity.
