Quizplus · Accepted Answer

Weak or absent patellar reflexes are a sign of early magnesium sulfate toxicity. Other signs that may occur later include respiratory and cardiac depression, decreased urine output, and loss of consciousness. Complaints of feeling flushed and warm may be a common side effect of magnesium sulfate but does not necessarily indicate toxicity. A respiratory rate of 16 and fetal heart rate of 120 are within normal limits.
