An accident victim receives a blood transfusion. Shortly thereafter, he begins to have difficulty breathing, develops a fever, and experiences nausea and vomiting. Which of the following is the most likely interpretation of these events?
a. the blood transfusion contained pyrogens. b. the blood transfusion was mismatched, and the recipient had previously been exposed to the blood group antigens of the blood transfusion. c. the blood transfusion was mismatched and contained pyrogens. d. the blood transfusion was mismatched. e. the recipient had previously been exposed to the blood group antigens of the blood transfusion.

b. the blood transfusion was mismatched, and the recipient had previously been exposed to the blood group antigens of the blood transfusion.

Explanation:

Blood transfusion giving a patient blood or its equivalent product intravenously. Necessary tests are normally carried out to ensure the blood to be transfused matches and is compatible with the blood or body system of the recipient.

However when symptoms like difficulty in breathing, fever,nausea and vomiting is visible after ten transfusion then it’s obvious there was an error which involves blood transfusion being mismatched, and the recipient being previously been exposed to the blood group antigens of the blood transfusion

the correct answer would be 6 feet.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
