Final answer:
An unconscious 18-year-old Jehovah's Witness patient would likely refuse a blood transfusion based on their religious beliefs, as Jehovah's Witnesses are known to prohibit blood transfusions on scriptural grounds. Adult patients have the right to refuse medical treatment for religious reasons, and this would apply to this patient if their stance on blood transfusions was known prior to their incapacitation.
Step-by-step explanation:
In the case of an unconscious 18-year-old Jehovah's Witness patient requiring a blood transfusion, based on their religious beliefs, option b) They would likely refuse the blood transfusion due to religious beliefs is the most accurate. Jehovah's Witnesses are known for a religious doctrine that prohibits blood transfusions, and this stance is usually well-documented in their medical files or made known through medical bracelets or cards. In emergency situations where consent cannot be obtained and if there are no clear instructions from the patient, this presents an ethical dilemma to medical staff.
Jehovah's Witnesses believe that the Bible prohibits ingesting blood and that this extends to accepting blood transfusions, even if they could be life-saving. This belief is drawn from several scriptural passages, including Acts 15:28-29, which commands Christians to 'abstain from blood.' Over time, the legal system has come to respect the right of adult patients to refuse medical treatment, including blood transfusions, for religious reasons, and this would apply to the Jehovah's Witness patient.
If the patient had been conscious or if advance directives were available, it would be expected that they would refuse the transfusion. If the individual is a minor, the situation can become more complex, as parents or guardians may have the authority to refuse treatment on behalf of their underage children, but this power is not absolute, especially when refusing treatment could result in death. In contrast, since the patient in the scenario is 18 years old, they would be considered an adult, and their own advance directives or previously stated wishes would take precedence.
