Please Read the Clinical Scenario, and Then Answer the Question

Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format.
Jared is a 34-year-old male who has reported several weeks of general malaise, and a low-grade fever. You are a nurse working for the public health department, and you are corresponding with Jared concerning the results of his laboratory testing.
-You inform Jared that a Western blot test will be performed to confirm or deny diagnosis.You tell Jared that the Western blot test is a more specific test.This time,you catch yourself using medical jargon again,and clarify in which of the following ways:

A) "It's possible that this is a false-positive,since the test may have been positive for something other than HIV."
B) "The Western blot test is a more specific test and is unlikely to generate a false positive result.This will be used to confirm or refute the ELISA test results."
C) "It's possible that this is a false-positive,since high sensitivity means the tests are rarely accurate."
D) "It's unlikely that there would be a false-positive result,since this is the only test that can really diagnose HIV."
