Final answer:
The highest priority during extrication is ensuring personal safety (option B) to avoid becoming an additional victim. Other priorities follow, including maintaining the patient's airway, controlling major bleeding, and gaining access to the patient. O negative blood is used in emergencies for its universal compatibility, and the goals of U.S. foreign policy include safety, market access, and protecting human rights.
Step-by-step explanation:
The question pertains to the highest priority during extrication of a patient. Extrication refers to the process of safely removing a patient from a dangerous or compromised situation, such as from the wreckage of a vehicle after an accident.
Among the given options, the highest priority is B. Ensuring your personal safety. This is because rescuers must first ensure their own safety to avoid becoming additional victims that require rescue, which would further complicate the emergency response.
Once personal safety is guaranteed, other priorities can be attended to in the correct order, which often follows the pattern of:
- Maintaining the patient's airway (C),
- Controlling major bleeding (A), and
- Gaining access to the patient (D).
To address the other parts of the question: In case of a motor vehicle accident with critical conditions such as severe bleeding where patient's blood type is unknown, O negative blood is transfused because it is considered the universal donor type and is most likely to be compatible with any patient.
Regarding the goals of U.S. foreign policy, the correct answer is D. all the above, as these are all crucial aspects of foreign policy objectives.
