Final answer:
The correct option is D. Disentanglement of the patient. During an auto extrication, the next goal after gaining patient access is the disentanglement of the patient. In traumatic emergencies where blood type is unknown.
Step-by-step explanation:
The next goal during an auto extrication, once access to the patient has been gained, is D. Disentanglement of the patient. This step involves removing any obstacles that are trapping the patient, such as bent metal, a crushed door, or a collapsed dashboard, and creating sufficient space to safely extricate the patient from the vehicle without causing further injury.
As for the second part of the question, in an emergency where a patient is rushed to the emergency department with multiple traumatic injuries and severe bleeding, and there is no time to determine their blood type, the type of blood transfused is O negative. This is because O negative blood is considered the universal donor in emergency settings, as it is compatible with all other blood types and carries the least risk of causing an adverse reaction in the patient when the blood type is unknown.
