Hint : No reflexes = danger sign 🚨

Correct Answers:

  • Absent deep tendon reflexes


Rationale :

🧠 Magnesium sulfate toxicity depresses neuromuscular transmission, with absent or diminished DTRs being a critical early sign.

🧠 Normal signs of magnesium effect include reduced contraction frequency, slight drowsiness, and mild flushing.

🧠 Urine output of ≥30 mL/hr is acceptable, but DTR absence signals possible progression to respiratory paralysis.

🧠 Always monitor DTRs, respiratory rate, and urine output to ensure safe serum levels.
