Passage / Scenario
A nurse is assisting with monitoring a client who has preeclampsia and is receiving magnesium sulfate. The client's respiratory rate is 8 breaths/min and the nurse suspects toxic levels of magnesium.Which of the following should the nurse administer?
Correct answer
A
Rationale
The correct answer is A: Calcium gluconate. In cases of calcium channel blocker toxicity, calcium gluconate is administered to counteract the effects of the overdose by increasing calcium levels and improving cardiac contractility. Flumazenil (B) is used for benzodiazepine overdose, naloxone (C) for opioid overdose, and protamine sulfate (D) for heparin overdose. Calcium gluconate is the appropriate choice in this scenario due to the indication of calcium channel blocker toxicity.
