Sample NBCMI - National Board of Certification for Medical Interpreters Practice Questions
Try these questions from our free NBCMI - National Board of Certification for Medical Interpreters practice tests. The correct answer and an explanation follow each question.
A patient with coronary artery disease is informed they will undergo a procedure where a catheter with a small balloon is used to widen a blocked artery. Which medical procedure is being described?
- A. Coronary Artery Bypass Graft (CABG)
- B. Angioplasty
- C. Atherectomy
- D. Echocardiogram
Answer: B. Angioplasty
Angioplasty is a minimally invasive procedure specifically designed to widen narrowed or obstructed arteries by inflating a balloon at the site of the blockage. A CABG is open-heart surgery to create a new path for blood flow. An atherectomy involves removing plaque from the artery, and an echocardiogram is a diagnostic ultrasound of the heart.
Which of the following actions best demonstrates the application of the NBCMI Standard of Practice regarding Confidentiality?
- A. Discussing a challenging case with a fellow interpreter in a public cafeteria to get advice.
- B. Using a patient's name and diagnosis in a personal glossary stored on a private, password-protected computer.
- C. Sharing general information about a patient's condition with the patient's concerned family members in the waiting room.
- D. Shredding any hand-written notes taken during an interpreting session immediately after the encounter is complete.
Answer: D. Shredding any hand-written notes taken during an interpreting session immediately after the encounter is complete.
The standard of Confidentiality requires the interpreter to protect all patient information learned during the performance of their duties. Shredding notes containing Protected Health Information (PHI) is a critical step to ensure that written information is not compromised. The other options all represent breaches of confidentiality, regardless of intent or location.
After an interpreting session, a medical interpreter is in the hospital cafeteria and is approached by a friend who is a nurse in a different department. The nurse asks, 'I saw you with Mr. Smith. Is his cancer back?' How must the interpreter respond to be compliant with HIPAA?
- A. Confirm the diagnosis but ask the nurse to keep it confidential.
- B. State, 'I cannot discuss any patient information due to confidentiality laws.'
- C. Suggest the nurse look up the patient's information in the hospital's electronic health record system.
- D. Say 'I don't know' even if the interpreter knows the answer.
Answer: B. State, 'I cannot discuss any patient information due to confidentiality laws.'
HIPAA's Privacy Rule strictly prohibits discussing patient information with anyone not directly involved in the patient's care, even other healthcare professionals. Disclosing PHI in a public setting is a clear violation. The only compliant response is to refuse to share any information by citing confidentiality rules. Acknowledging the person is a patient or discussing their condition is a breach of privacy.
A medical interpreter is in an appointment where the doctor uses a complex medical term. The interpreter notices the patient has a confused expression. Which of the following actions aligns with the interpreter's role as a 'Clarifier'?
- A. Continuing to interpret the term verbatim and hoping the patient will ask for clarification.
- B. Pausing the session to explain the medical concept to the patient in their own words.
- C. Alerting the provider to the patient's non-verbal cue and stating, 'The interpreter would like to clarify, may I ask the doctor to explain that term in simpler language?'
- D. Ignoring the patient's confusion as it is the provider's responsibility to ensure comprehension.
Answer: C. Alerting the provider to the patient's non-verbal cue and stating, 'The interpreter would like to clarify, may I ask the doctor to explain that term in simpler language?'
As a Clarifier, the interpreter's role is to ensure that the meaning is understood. The most professional way to do this is to manage the communication by alerting the provider and requesting they explain the term simply. This keeps the provider in control of the information being shared and avoids the interpreter stepping out of their role by providing medical explanations.
