Which of the following is the earliest sign of magnesium toxicity in a patient with eclampsia on treatment with magnesium sulphate?
Correct Answer: Loss of deep tendon reflexes
Description: Throughout the administration of magnesium, the patient needs continuous clinical monitoring for magnesium toxicity. Toxicity is manifested by loss of deep tendon reflexes (patellar), decrease in respiratory rate, oliguria and altered mental status. Comparatively, loss of deep tendon reflexes appears to be the earliest of all the signs and it occurs when the magnesium level exceeds 5 mmol/L.
