Peripheral circulatory failure. 5. Liver failure. A. Lowered central venous pressure. B. A raised plasma bicarbonate level. C. Metabolic acidosis and anaemia. D. Raised central venous pressure. E. A lowered blood urea. |
|
Answer» A. Option 4 Peripheral circulatory failure. In circulatory failure such as may occur in severe shock or haemorrhage, the fall in venous return to the heart lowers central venous pressure. B. Option 2 Respiratory failure. The retention of CO2 in respiratory failure leads to an acidosis that is compensated for by generation of bicarbonate by the kidney. C. Option 1 Renal failure. In renal failure, failure to excrete acid residues of metabolism causes acidosis. Anaemia is often seen since erythropoietin is normally manufactured by the kidneys. D. Option 3 Heart failure. In heart failure where the heart cannot pump forward all the blood being delivered to it, there is a rise in central venous pressure that increases the diastolic filling of the heart. E. Option 5 Liver failure. The liver is responsible for the deamination of amino acids and the conversion of the NH4 residues into urea. |
