Final answer:
The medical assistant should ask for assistance from a bilingual staff member to ensure effective communication with the patient.
Step-by-step explanation:
When a medical assistant encounters a patient who does not speak the same language, the most appropriate action to take is to ask a bilingual staff member to assist with communication. This ensures accurate and effective communication, which is critical in the healthcare setting. Using medical terminology with a patient who may not understand the language can create confusion, and while using body gestures can aid in communication, they should not be the sole method as they can be misinterpreted. Therefore, involving a bilingual individual is the best approach for clear communication, maintaining professionalism, and ensuring the patient receives the best possible care.
