Pathophysiology and clinical medicine

1. Image of object focusing in front of retina is typical of:

Myopia (short sightedness, near-sightedness)
Hyperopia (hypermetropia - long-sightedness, far-sightedness)
Presbyopia
Hyperopia, but only when a patient sees the object through the concave lens

2. Elevation of creatin kinase (CK) typically does not accompany

Severe chest pain
Anuria
Chronic alcohol abuse
Epileptic seizures of grand-mal type

3. The term "thromboembolic disease" comprises:

pulmonary embolism and brain embolism (both of thrombotic origin)
phlebothrombosis and pulmonary embolism
thrombophlebitis and pulmonary embolism
pulmonary embolism from phlebothrombosis (class A) and pulmonary embolism from thrombophlebitis (class B)

4. Phospholipases do not belong to

Hydrolases
Lipases
Phosphodiesterases
Phosphorylases

5. With sodium plasma concentration 140 mmol/l calculate how much sodium is filtered into primary urine in 24 hr; take sodium atomic mass rounded to 23 g/mol

32 g
64 g
100 g
0,5 kg

6. Choose the false answer: Crohn disease

Can affect any segment of gastrointestinal tract from oral cavity to anus, but most frequently it is affecting the terminal ileum or proximal colon
Frequently affects the caecum and anus
Affects most often terminal ileum, caecum and anus
Affects most often the terminal ileum, less frequently the proximal ileum, but never affects the segment distally from transverse colon (here we call it ulcerative colitis)

7. 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

8. Irritable bowel syndrome (IBS) belongs to:

Functional bowel disorders
Inflammatory bowel diseases
Precanceroses
Consequences of amoebic colitis

9. 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)

10. 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
