When caring for a client with preeclampsia on magnesium sulfate, what is the highest priority item the nurse should have available?

When caring for a client with preeclampsia who is receiving magnesium sulfate, having calcium gluconate injection readily available is of utmost importance. This is due to the potential risk of magnesium sulfate toxicity, which can occur in patients receiving this medication for seizure prevention.

Calcium gluconate acts as an antidote to reverse the effects of magnesium sulfate when toxicity occurs by providing calcium that may be depleted due to elevated magnesium levels affecting neuromuscular transmission and cardiac function. Therefore, in emergency situations, having calcium gluconate on hand allows for prompt management of any adverse reactions associated with magnesium sulfate.

In contrast, while IV saline solution and magnesium sulfate replacement may be important in managing the patient’s overall hydration status and electrolyte balance, they are not specifically lifesaving in the case of magnesium toxicity. Vitamin K injection is also unrelated to magnesium sulfate therapy and typically used for different indications related to clotting factors. Overall, the readiness to administer calcium gluconate is critical in ensuring patient safety and effectively managing the risk of complications from magnesium sulfate treatment.
