Quite thrilled that I got this right. I have always sucked at CR. Anyways, here goes my logic.
(A) Since a physician acts both as a professional person and as a citizen, it is not ethical for a physician to conceal information about patients from duly constituted law enforcement agencies that have proper jurisdiction.
Incorrect. This is not compatible with the requirement to report gunshot wounds.
(B) Since a patient comes to a physician with the expectation that the patient’s visit and medical condition will remain confidential, it is not ethical for a physician to share this information with anyone except personnel within the physician’s office.
Incorrect. This is not compatible with the requirement to report infectious diseases.
(C) Since the primary concern of medicine is individual and public health, it is not ethical for a physician, except in the case of gunshot wounds, to reduce patients’ willingness to come for treatment by a policy of disclosing their identities to law-enforcement agencies.
Correct. The concern here is individual and public health. Disclosing infectious diseases would be compatible with this principle. Hence the requirements in the passage i.e. reporting gunshot wound (by way of exception to the rule) and reporting infectious disease (compatible with the rule -- concern for public health). Reporting a non-infectious disease in this case would violate the ethics.
(D) Except as required by the medical treatment of the patient, physicians cannot ethically disclose to others information about a patient’s identity or medical condition without the patient’s consent.
Incorrect. It isn't compatible with the requirement to disclose gunshot wounds.
(E) Except to other medical personnel working to preserve or restore the health of a patient or of other persons, physicians cannot ethically disclose information about the identity of patients or their medical condition.
Incorrect. It isn't compatible with the requirement to disclose gunshot wounds or infectious diseases.
