A medication error has occurred, and the client has received double the ordered dosage of magnesium sulfate. The nurse anticipates the physician will order what medication STAT?

  1. chlordiazepoxide (Librium)
  2. vitamin K
  3. naloxone (Narcan)
  4. calcium gluconate
Number 4 is correct.
Rationale: Calcium gluconate is given as an antidote to counteract magnesium sulfate toxicity. Magnesium sulfate toxicity is dangerous because it can cause respiratory depression and hypotension. Chlordiazepoxide (Librium) is used to assist patients in alcohol withdrawal. Naloxone (Narcan) is used in case of an opioid overdose. Vitamin K would be given to increase clotting.
