In which scenario can a family member act as an interpreter for a client?

When considering the role of a family member as an interpreter for a client, the scenario where all professional interpreter options have been exhausted is significant. This is because using a professional interpreter is essential for ensuring accurate and unbiased communication, as they are trained to interpret in a neutral manner without personal influence or emotional involvement in the situation.

If professional options are unavailable or have been thoroughly explored — perhaps due to a lack of availability of qualified interpreters or logistical challenges — then a family member may step in to provide immediate assistance. However, this should be a last resort to protect the integrity of the communication, as family members can inadvertently introduce bias or misunderstand the nuances of the conversation due to their relational dynamics with the client. Therefore, the correct answer highlights the importance of exhausting all professional avenues before involving family members in interpretation.
