Step-by-step explanation:
The question addresses the procedural steps that must be taken before an HIV test can be administered to an individual. Specifically, the correct action is b. A consent form must be signed by the applicant prior to the test. This action is in accordance with legal and ethical standards that protect individuals' privacy and autonomy, ensuring that they are fully informed about the implications of the HIV test and their consent is obtained before proceeding.
While this question pertains to insurance applicants, the same principle of informed consent applies to patients in healthcare settings, where hospitals may decide to test patients for HIV to minimize risks of false negatives, to counsel patients for false positives, and to react responsibly to potential exposure incidents. Early detection of HIV is crucial, and informed consent is a key ethical component of any testing protocol.
