A nurse is assessing a client who has severe preeclampsia and is receiving magnesium sulfate via continuous IV infusion.
Which of the following findings should alert the nurse to suspect magnesium toxicity?
Respiratory rate 10/min
Urine output 40 mL/hr
Patellar reflex 2+
Serum magnesium level 4.5 mEq/L
The Correct Answer is A
Respiratory rate 10/min. This indicates muscle weakness and difficulty breathing, which are symptoms of magnesium toxicity. Magnesium sulfate is a medication that can cause magnesium overdose if given in excess or if the patient has impaired kidney function.
Choice B. Urine output 40 mL/hr is wrong because this is within the normal range for urine output, which is 30 to 50 mL/hr. Urine output may decrease in severe cases of magnesium toxicity due to urine retention.
Choice C. Patellar reflex 2+ is wrong because this is a normal finding for the knee-jerk reflex. A low or absent patellar reflex may indicate magnesium toxicity, as it reflects muscle weakness and nerve dysfunction.
Choice D. Serum magnesium level 4.5 mEq/L is wrong because this is within the normal range for serum magnesium, which is 1.7 to 2.3 mEq/L. Serum magnesium levels above 2.6 mEq/L can indicate hypermagnesemia or magnesium overdose.
