Final answer:
In the care of a patient with critical internal bleeding, the EMT must prioritize the ABCs and may administer type O negative blood due to its universal donor status. Agglutination with both anti-A and anti-B antibodies signifies blood type AB. A Type I error in the medical context refers to incorrectly diagnosing a condition (like a blood-borne illness) when it is not present.
Step-by-step explanation:
Management of a Patient with Internal Bleeding
When caring for a patient with internal bleeding, particularly following a major trauma such as a motor vehicle accident, an Emergency Medical Technician (EMT) must first ensure the patient's airway is clear, they are breathing, and circulation is adequate (ABCs). If the patient is experiencing severe bleeding and there is no time to determine the blood type, type O negative blood is administered. This is because type O negative is the universal donor and can be accepted by individuals of any blood type without the risk of severe transfusion reactions.
Regarding the question about blood typing in the laboratory setting, if both anti-A and anti-B antibodies cause agglutination in the patient's blood sample, this indicates that the patient has blood type AB, which is a normal response and not a technical error. Blood type AB individuals have both A and B antigens on the surface of their red blood cells, so they will agglutinate when exposed to both types of antibodies.
In an emergency medical scenario, if a patient is at high risk for a blood-borne illness and a Type I error in the context of rejecting a null hypothesis occurs, this would mean that the paramedics mistakenly conclude that the patient has a blood-borne illness when in fact, they do not. Making such an error could lead to unnecessary treatments or precautions that could affect the patient adversely.
