A nurse is assessing a client who is receiving IV magnesium sulfate for treatment of preeclampsia. Which of the following findings should the nurse report?

A. 1+ deep tendon reflexes: Decreased deep tendon reflexes indicate magnesium toxicity, as excessive magnesium depresses neuromuscular activity. This finding suggests the serum magnesium level may be too high and requires immediate reporting to prevent respiratory or cardiac complications. B. Pupils equal, round, react to light, accommodation: Normal pupillary response does not indicate magnesium toxicity. This finding shows intact neurological function and does not require intervention. C. Blood pressure 122/88 mm Hg: This blood pressure is within acceptable range for a client receiving magnesium sulfate for preeclampsia. It suggests that the medication is helping control hypertension without causing hypotension. D. 24 hr urine output 960 mL: This urine output is adequate (greater than 30 mL/hr average) and indicates proper renal function. Since magnesium is excreted through the kidneys, normal urine output helps prevent accumulation and toxicity.
