40. A blood gas sample was collected from a patient under monitoring for an existing acid-base disorder. The sample wassent to the laboratory in an ice bath but it was found that an air bubble was present in the syringe used. The blood hasalso been exposed to room air for about 30 minutes. What changes have most likely occurred in the sample?A. elevated CO2 content, PCO2 decreasedB. elevated CO2 content, elevated PO2 and pHC. decreased C02 content, decreased pH and PCO2D. elevated PO2, decreased HCO341.

6. A 60-year-old man has been smoking since his 30s. After a heated argument with his colleagues in office he experienced an acute pain across his chest, associated with shortness of breath, a sense of light-headedness and sweating. He was rushed to the hospital emergency department, where his clectrocardiogram showed changes consistent with an acute infarction. Blood was sent to the laboratory for biochemical tests, including the total cholesterol, LDL cholesterol and HDL cholesterol. The blood lipid levels (in mg/dL) were: TAG – 290, total cholesterol - 325, LDL cholesterol – 245, HDL cholesterol - 25. The patient was treated intensively and got better. Before he was discharged from the 7.13. Hypercholesterolemia. Biochemical Aspects of Atherosclerosis. Cholesterol-Lowering Agents 393 hospital, his physician told him that his infarction is the result of a long history of smoking. Explain the conclusion of the specialist. For that: a) explain the functions of lipoproteins in…
