Final answer:
A medical assistant should use a qualified medical interpreter when checking in a patient who does not speak the same language.
Step-by-step explanation:
The medical assistant should use a qualified medical interpreter when checking in a patient who does not speak the same language. This ensures that accurate communication and understanding can take place, reducing the risk of misunderstandings or errors in medical care.
Using family members as interpreters is not recommended as they may not have the necessary medical knowledge or understanding of terminology to accurately convey information.
Speaking loudly or avoiding eye contact are not appropriate actions to take in this situation.
