A patient taking amitriptyline is found unconscious after taking an unknown number of tablets. Which assessment is the priority?
Correct answer: B. Obtain an electrocardiogram and monitor rhythm
- A. Assess bowel sounds and abdominal distension
- B. Obtain an electrocardiogram and monitor rhythm
- C. Ask about the patient's usual sleep pattern
- D. Check for increased appetite and weight gain
Explanation
Tricyclic antidepressant overdose can cause life-threatening cardiac conduction disturbances and dysrhythmias, so cardiac monitoring and an ECG are priorities after airway and breathing are assessed. Constipation, appetite change, and sleep pattern are not the immediate threat.
