A clinic observes a 49 year old patient with significant prolongation of coagulation time,



Gastrointestinal haemorrhages, subcutaneous hematomas. These symptoms might be explained

By the deficiency of the following vitamin:

A K

B B1

C B6

D H

E E

      83

Examination of a patient revealed hyperkaliemia and hyponatremia. Low secretion of which

Hormone may cause such changes?

A Aldosteron

B Vasopressin

C Cortisol

D Parathormone

E Natriuretic

      84

Examination of a 43 y.o. anephric patient revealed anemia symptoms. What is the cause of

These symptoms?

A Reduced synthesis of erythropoietins

B Enhanced destruction of erythrocytes

C Iron deficit

D Vitamin B12 deficit

E Folic acid deficit

      85

A man is being measured power inputs on an empty stomach, in the lying position, under

Conditions of physical and psychic rest at a comfortable temperature. Power inputs will reach the

Maximum at:

A 5-6 p.m.

B 7-8 a.m.

C 10-12 a.m.

D 2-3 p.m.

E 3-4 a.m.

      86

When measuring power inputs of a man by the method of indirect calorimetry the following

Results were obtained: 1000 ml oxygen consumption and 800 ml carbon dioxide liberation per

Minute. The man under examination has the following respiratory coefficient:

A 0,8

B 1,25

C 0,9

D 0,84

E 1,0

      87

While determining power inputs of a patient’s organism it was established that the respiratory

Coefficient equaled 1,0. This means that in the cells of the patient the following substances are

Mainly oxidized:

A Carbohydrates

B Proteins

C Fats

D Proteins and carbohydrates

E Carbohydrates and fats

      88

A patient has a disturbed absorbtion of fat hydrolysates. It might have been caused by a deficit

In the small intestine cavity:

A Of bile acids

B Of bile pigments

C Of lipolytic enzymes

D Of sodium ions

E Of liposoluble vitamins

      89

Inhabitants of territories with cold climate have high content of an adaptive thermoregulatory

Hormone. What hormone is meant?

A Thyroxin

B Insulin

C Glucagon

D Somatotropin

E Cortisol

      90

A concentrated solution of sodium chloride was intravenously injected to an animal. This caused

Decreased reabsorption of sodium ions in the renal tubules. It is the result of the following

Changes of hormonal secretion:

A Aldosterone reduction

B Aldosterone increase

C Vasopressin reduction

D Vasopressin increase

E Reduction of atrial natriuretic factor

      91

Accelerated frequency of the heart rate and increased blood pressure were marked in the

Sportsman on the start before the competitions. Influence of what parts of the CNS can explain

These changes?

A Cortex of the large hemispheres

B Medulla

C Mesencephalon

D Diencephalon

E Hypothalamus

      92

People adapted to high external temperatures have such pecularity: profuse sweating isn't

Accompanied by loss of large volumes of sodium chloride. This is caused by the effect of the

Following hormone upon the perspiratory glands:

A Aldosterone

B Vasopressin

C Cortisol

D Tgyroxin

E Natriuretic

      93

During an experiment the dorsal roots of the spinal cord of an animal have been cut. What

Changes will be observed in the innervation zone?

A Sensitivity loss

B Loss of motor functions

C Decrease in muscle tone

D Increase in muscle tone

E Sensitivity loss and loss of motor functions

      94

As a result of destruction of certain brainstem structures an animal has lost its orientative

Reflexes in response to strong photic stimuli. What structures were destroyed?

A Anterior tubercles of quadrigeminal plate

B Posterior tubercles of quadrigeminal plate

C Red nuclei

D Vestibular nuclei

E Black substance

      95

As a result of damage to certain structures of brainstem an animal lost orientation reflexes.

What structures were damaged?

A Quadritubercular bodies

B Medial nuclei of reticular formation

C Red nuclei

D Vestibular nuclei

E Black substance

      96

Osmotic pressure of a man's blood plasma is 350 mosmole/l (standard pressure is 300

Mosmole/l). First of all it will result in high secretion of the following hormone:

A Vasopressin

B Aldosteron

C Cortisol

D Adrenocorticotropin

E Natriuretic

      97

A hypertensive glucose solution was introduced to a patient. It will intensify water movement:

A From the cells to the intercellular liquid

B From the intercellular liquid to the capillaries

C From the intercellular liquid to the cells

D From the capillaries to the intercellular liquid

E There will be no changes of water movement

      98
