The NBVME has selected the following 33 questions to provide candidates with an example of the type of questions that appear on the Qualifying Examination. An answer key follows the list of questions. These sample questions were chosen to represent the five general content areas of the examination (anatomy, physiology, pharmacology, microbiology, and pathology), but they do not address all of the individual content areas listed in the examination blueprint.
Approximately 7% of the items on the QE will contain graphic or pictorial information (such as a chart, photgraph, or radiograph), but none of the following sample items include any pictorial information. To get an idea of what pictorial items look like, you may refer to the sample NAVLE items available here.
