A patient is brought to the emergency department after taking amitriptyline. The patient is hypotensive, drowsy, and has a widened QRS complex on the ECG. Which treatment should the nurse anticipate?

Correct answer: A. Intravenous sodium bicarbonate

  • A. Intravenous sodium bicarbonate
  • B. Intravenous calcium gluconate
  • C. Oral activated charcoal only
  • D. Intramuscular naloxone

Explanation

Sodium bicarbonate helps correct the cardiac sodium-channel blockade and metabolic acidosis associated with serious tricyclic antidepressant poisoning. Calcium treats some calcium-channel blocker problems, while naloxone is used for opioid toxicity.
