I would say, no you are not wrong for feeling that way. I do believe the current recommendation is that a facility must have certified medical translators (general translators aren't all certified to interpret in medical situations). If you are not credentialed as a medical interpreter, you should not be doing such. For a quick non medical translation (are you hungry? do you have pain?) not as much of an issue if you are able to complete your other duties. Seems like they are taking advantage of your linguistic skills. One hospital I worked at offered compensation to qualified staff to work as non-medical interpreters. Some licensed staff were offered the opportunity to become credentialed as medical interpreters (paid training and compensation when used as medical interpreters).
White paper on the joint commission regulations: http://www.languageline.com/main/fil...ion_012411.pdf
'Even though federally funded hospitals and other facilities are required by law to provide access to competent language services, the regulations are often loosely followed. Many organizations are uninformed, and their support staff is ill prepared to access the appropriate services. Some hospitals continue to assist LEP patients by relying on patient family members, untrained bilingual staff, unmonitored contract interpreters, poorly tested language service providers, or some combination of them all.
To meet the standards, medical interpreters—whether they work full time, part time, or through a service provider—must have a formal education and be trained and assessed specifically in medical interpretation. In addition, human resources departments are expected to maintain files for all medical interpreters, regardless of their employee status. As part of The Joint Commission tracer reviews, hospitals
are expected to provide surveyors with documentation proving that each interpreter has undergone competency assessment. This same level of documentation must be included in all remote language service provider contracts. Contracts must also provide assurance that the service providers’ competency standards are consistent with the hospital’s internal requirements. Consistent with existing federal, state and local laws The Joint Commission standards also require written translations for vital documents such as informed consent documentation, complaint forms, and information on the availability of free language assistance programs"
