Final answer:
Magnesium sulfate is used to prevent seizures in preeclampsia by reducing neuromuscular conduction. The antidote for magnesium sulfate toxicity is calcium gluconate. Toxic effects are indicated by reduced reflexes, respiratory depression, and reduced urine output.
Step-by-step explanation:
Magnesium sulfate is a medication used to prevent seizures in women with preeclampsia, a condition that can occur during pregnancy and is characterized by high blood pressure and often protein in the urine. It acts as a depressant for the central nervous system, reducing the risk of seizures associated with preeclampsia.
A. Purpose of administering magnesium sulfate
The purpose of administering magnesium sulfate is to prevent the onset of seizures in preeclampsia, which is known as eclampsia when seizures occur.
B. Main action of magnesium sulfate
The main action of magnesium sulfate is to reduce neuromuscular conduction, which in turn helps prevent seizures.
C. Antidote for magnesium sulfate
The antidote for magnesium sulfate toxicity is calcium gluconate, which can help reverse the effects of magnesium overdose.
D. Assessment findings indicating toxic effects
- Reduced or absent deep tendon reflexes
- Respiratory depression
- Oliguria or reduced urine output
