A nurse on a crisis hotline is speaking to a client who says, "I just took an entire bottle of amitriptyline." Which of the following responses should the nurse make?

Choice A reason: Asking about intent may be important later, but the immediate priority is emergency intervention. This delays life-saving action. Choice B reason: Asking how many pills were taken is useful for assessment but does not address the immediate need for emergency medical care. Choice C reason: This is the correct response. Amitriptyline overdose is life-threatening due to risk of cardiac arrhythmias and CNS depression. The nurse must act immediately to send emergency services. This response ensures safety and rapid intervention. Choice D reason: Acknowledging feelings is therapeutic but not appropriate in an acute overdose crisis. Immediate emergency response is required.
