1. clearance test for creatinine measures early loss of renal function concentrating ability glomerular filtration rate tubular secretion 2. cyanosis does not occur in severe anemia because oxygen carrying capacity of available Hb is increased critical conc of Hb required to produce cyanosis is reduced oxygen hemoglobin curve shift to the right hypoxia stimulates erythropoietin production 3. Under normal conditions, the main drive for respiration is the arterial PCO2 acting through peripheral chemoreceptors arterial PCO2 acting through central chemoreceptors arterial pH acting through central chemoreceptors arterial pH acting through peripheral chemoreceptors 4. Which of the following would shift the oxygen-hemoglobin dissociation curve to the right? Carbon monoxide poisoning Decreased PCO2 Decreased temperature Decreased pH 5. pulmonary compliance is decreased in all of the following conditions except COPD pulmonary congestion decrease surfactant pulmonary fibrosis 6. Diffusion capacity of carbon monoxide is decreased in all except Pulmonary vascular disease Emphysema Interstitial lung disease Polycythemia 7. venous return to heart during quiet standing is facilitated by all of the following factors except valves in perforators gravitational increase in arterial pressure calf muscle contraction during standing sleeves of deep fascia 8. In which portion of the kidney tubule is most water normally reabsorbed? Loops of Henle Cortical collecting duct Proximal tubule Distal tubules 9. The medical record of a patient indicates a systolic murmur due to increase in afterload, producing a pressure gradient between the ventricle and aorta during ejection. Which of the following best describes the condition? Aortic stenosis Aortic insufficiency Mitral stenosis Mitral insufficiency 10. Which of the following plant components is not fermented by gastrointestinal microorganisms Hemicellulose Cellulose Lignin Pectin 11. during diastole the arterial pressure is maintained by elastic recoil of aorta constriction of capillaries contraction of left ventricle musculature of arteries 12. Pulmonary circulation is characterised by vasodilation in response to hypoxia vasoconstriction in response to hypoxia Vasoconstriction in response to hypercapnia Resistance is greater than systemic circulation 13. The oxygen-hemoglobin dissociation curve shifts to the left under which of the following circumstances? Decreased pH Carbon monoxide poisoning Increased 2,3-diphosphoglycerate (2,3-DPG) D. Increased PCO2 Increased temperature 14. An elevated level of which of the following substances would identify a specimen as plasma rather than serum? Erythrocytes Albumin Granulocytes Fibrinogen 15. an important non respiratory function of lungs is calcium balance sodium balance potassium balace anion balance 16. which of the following is not a primary taste sour sweet chilli bitter 17. gastroesophageal reflex occurs mainly due to hypotensive lower eosophageal sphincter inadequate esophageal clearance temporary/intermittent loss of tone of lower eosophageal sphincter hiatus hernia 18. Bile acids consist of all except Deoxycholic add Chendeoxycholic acid Taurocholic acid Lithocholic acid 19. maximum phosphate is reabsorbed in Collecting duct PCT Loop of henle DCT 20. Cerebral perfusion pressure is Arterial pressue x venous pressure Venous pressure minus arterial pressure Arterial pressure minus intracranial pressure Arterial pressure minus peripheral venous pressure Loading … Question 1 of 20
