The nurse is caring for a client who is receiving magnesium sulfate for preeclampsia. Which finding indicates magnesium toxicity?
Correct answer
A
Rationale
A respiratory rate of 10 breaths per minute suggests magnesium toxicity as magnesium sulfate depresses the central nervous system including respiratory drive. Normal reflexes adequate urine output and BP of 140/90 do not indicate toxicity.
