Which of the following providers can perform a thyroid biopsy?

The correct answer indicates that both Dr. Markman and Dr. Abndukwala are qualified to perform a thyroid biopsy. In medical practice, the ability to conduct specific procedures like a thyroid biopsy often depends on the physician's training, specialty, and experience. Generally, providers such as endocrinologists, surgeons, or radiologists who have received proper training can perform these biopsies.

Therefore, if both Dr. Markman and Dr. Abndukwala have the necessary qualifications and experience in thyroid procedures, then it is appropriate to state that they can carry out a thyroid biopsy. The inclusion of both indicates that the question is confirming their abilities rather than limiting the procedure to only one individual or excluding another qualified provider.

In contrast, Dr. Pourbabak’s exclusion suggests that they might not have the required expertise or specialty relevant to the procedure, which solidifies the choice of both Dr. Markman and Dr. Abndukwala as the correct responders to the question about who can perform the biopsy.
