Final answer:
Confirming the patient's identity before discussing sensitive information is the appropriate technique for outgoing calls with a patient as a medical assistant.
Step-by-step explanation:
The appropriate technique for outgoing calls when communicating on the telephone with a patient as a medical assistant is to confirm the patient's identity before discussing sensitive information. This ensures that the information is being shared with the correct person and maintains patient privacy and confidentiality. Speaking quickly to save time or using extensive medical jargon may confuse the patient and hinder effective communication. Additionally, providing medical advice without consulting a physician is not within the scope of a medical assistant's role.
