1. Least diffusible ion among following Cl – Na + urea K + 2. Which of the following is decreased as a result of hyperventilation? Arterial pH Arterial oxygen tension (PO2) Arterial oxygen content Cerebral blood flow 3. C ‘wave in JVP is due to Atrial filling with tricuspid valves closed Atrial contraction Bulging of tricuspid valve into the right atrium Rapid right ventricular filling 4. Best test for GFR is with Creatinine Inulin Hippuric acid PAH 5. With time, blood stored in a blood bank tends to become relatively depleted of 2,3- diphosphoglycerate (2,3-DPG). What effect does this have on the hemoglobin-oxygen dissociation curve? Shifts the curve to the left, so that the hemoglobin has a decreased oxygen affinity Shifts the curve to the right, so that the hemoglobin has a decreased oxygen affinity Shifts the curve to the left so that the hemoglobin has an increased oxygen affinity Shifts the curve to the right, so that the hemoglobin has an increased oxygen affinity 6. In the clotting process, as the hemostatic plug develops, fibrin polymerizes into monomeric threads that are held together by noncovalent bonds. Which clotting protein increases the strength of the clot by cross-linking the newly formed fibrin threads? Factor XIII Plasminogen High molecular weight kininogen (HMWK) Thrombin 7. An increase in which of the following is the most likely explanation for the swelling in the legs seen with congestive heart failure? Right atrial pressure Lymph flow Plasma colloid osmotic pressure Interstitial colloid osmotic pressure 8. Ptylin is secreted by Duodenal gland Salivary gland Gastric gland Pancreatic gland 9. Which of the following situations will lead to increased viscosity of blood Hypoglycemia Fasting state multiple myeloma amyloidogenesis 10. An increase in the concentration of 2,3 biphosphoglycerate (2,3DPG) may be seen in all of the following except Inosine Anemia Hypoxia Hypoxanthine 11. If diameter of a vessel is doubled Blood flow decreases four fold Blood flow increases four fold Blood flow increases sixteen fold Blood flow decreases sixteen fold 12. Absence of which of the following cell types is responsible for loss of vitamin B12 absorption? Chief cells Goblet cells G cells Parietal cells 13. Most important factor in transport across a membrane Size of particle Concentration gradient Charge of particle membrane thickness 14.

What role do the lungs play in the pathogenesis of systemic hypertension? The type II pneumocytes contain aldosterone The alveolar capillaries contain aldosterone The alveolar capillaries contain angiotensin-converting enzyme (ACE) The alveolar capillaries contain antidiuretic hormone (ADH) 20.
