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
