Pathophysiology and clinical medicine

1. 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

2. Synonymic term for pre-esophageal dysphagia is:

Neurogenic dysphagia
Paraesophageal dysphagia
Psychogenic dysphagia
Gastro-esophageal reflux (GER)

3. Rovsing's sign is positive when

There is a tachycardia accompanying the pain in the right hypochondrium
There is a tachycardia accompanying the edema (swelling) in only one of the both legs
Palpation (or the pressure of physician’s palm) of the left lower quadrant of a patient's abdomen increases the pain in the right lower quadrant
The patient is unable to keep balance while walking with closed eyes

4. 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)

5. 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

6. Lipases by their nature belong to

hydrolases
transferases
lyases
ligases

7. Commonly, sideroachrestic anemia is not

accompanied by sideroblasts
a sign of myelodysplastic syndrome
caused by repeated loss of blood (e.g. in young women)
caused by vitamin B6 deficiency

8. The most probable source of arterial embolism is:

Thrombus in left atrium
Thrombus popliteal vein
Thrombus in right ventricle
Thrombus in popliteal artery aneurysm

9. Dysphagia is:

A subjective symptom
An objective sign
An objective sign, that, however, a patient has to tell the physician he is suffering from
A subjective symptom, that, howver, does not include the pain (in case of pain odynophagia is the correct)

10. Alveolar air pressure is lower than atmospheric

during the whole inhalation
just before the inhalation begins; during the inhalation the alveolar pressure equals the atmospheric pressure
only in pneumothorax
alveolar air pressure is never lower than atmospheric pressure (contrary to intrapleural pressure)
