1. Common signs of Crohn disease do not include:

Diarrhea
Pain
Constipation
p-ANCA positivity with ASCA (antibodies against S. cerevisiae) negativity

2. Classical Virchow-Rokitanski triad does not include

alteration of blood flow (stasis or turbulence)
abnormality of blood coagulation (hypercoagulability)
medical history of thrombosis or embolism
injury of vessel wall (endothelial injury or dysfunction)

3. Typical causes of pre-esophageal dysphagia do not include:

Myasthenia gravis
Dermatomyositis
Sclerodermia

4. Ivermectin is:

A medicine used in the treatment of neonatal diarrhea
Well tolerated immunosupresiv used (a) in the treatment of rheumatoid arthritis and (b) in GVH reaction prevention after transplants

5. If 20% of cardiac output 5 l/min flows through kidneys, and 20 % of the plasma volume flowing through kidneys is filtered to glomerules, then calculate glomerular filtration rate (take hematokrit value 40 %). Calculated GFR value is:

2 ml/min
20 ml/min
100 ml/min
120 ml/min

6. Eponymic name for trisomy 21 is:

Down syndrome

7. Trombophilia means:

high platelet count in blood

8. Microcytic anemia is usually not

hypochromic at the same time
hyperchromic at the same time
caused by thalassemia
caused by repeated blood loss

9. With glomerular filtration rate (GFR) 80 ml/min, 100% filtration and 50% tubular reabsorption of substance X calculate its cearance:

160 ml/min
120 ml/min
80 ml/min
40 ml/min

10. Mechanism of action of diuretic furosemid consists in inhibiton of:
