| Test 144
After car accident a 60 -year old man is admitted to hospital by an ambulance. He is unconscious, his skin is pale, and his pulse and respiratory rate are increased. His blood test shows: RBC - 2, 52*1012/L, hemoglobin – 72 g/L, pO2 - 95 mmHg. Which of the following types of hypoxia does the patient have? Respiratory Hypoxic Hemic Circulatory Tissue Test 145 Hypercapnia, hypoxemia, and respiratory acidosis develop in a 42-year-old man after a bronchial asthma attack. Which of the following types of hypoxia does the patient have? Hypoxic Circulatory Anemic Tissue Histotoxic Test 146 A 28- year-old man complains of weakness and dyspnea during walking. On his examination the following changes in blood gases contents are identified: an increase of arterio-venous oxygen difference, hypoxia is diagnosed. Which of the following disorders is likely to be the cause of the hypoxia? Hypoxemia Anemia Respiratory failure Cardiac failure Poisoning with carbon monoxide Test 147 Several employees of a chemical plant are admitted to a hospital after accident at the plant. All patients complain of weakness, headache, dizziness, nausea, vomiting. Poisoning with nitrocompounds is suspected. Which of the following processes underlines hypoxia developed in the patients? Inhibition of dehydrogenases Inhibition of cytochrome oxidase Decrease of function of flavine enzymes Formation of methemoglobin Formation of carboxyhemoglobin Test 148 16-year old girl is admitted to hospital with cyanide poisoning. Her blood analysis shows decreased arterio-venous oxygen difference. Which of the following types of hypoxia does the patient have? Tissue Hypoxic Circulatory Anemic Respiratory Test 149 A 70- year old man suffers from chronic heart failure. On his examination cyanosis, dyspnea and edema of lower extremities are revealed. Which of the following types of hypoxia does the patient have? Anemic Respiratory Circulatory stagnant Circulatory ischemic Histotoxic Test 150 It is known that persons constantly living at high altitudes develop some adaptive reactions. Which of the following changes can be referred to adaptive one? An increase in RBCs Leukocytosis Hyperoxia Respiratory alkalosis Megaloblastic type of erythropoiesis Test 151 At a post-mortal examination it is established that a 23-year-old girl death results from cyanide poisoning. A disorder of which of the following processes is most likely to be the cause of her death? Tissue supply with oxygen Tissue respiration Hemoglobin synthesis Lung ventilation Hemoglobin saturation Test 152 Increased number of erythrocytes is revealed in the blood of people living in the mountains at altitude of 4000 m. Which of the following mechanisms is responsible for this phenomenon? Increased vitamin B12 synthesis Blood concentration Release of RBCs from their depots Increased erythropoietin synthesis A decrease in the circulating blood volume Test 153 A 57- year old man fell asleep inside his car with the engine running and died from carbon monoxide poisoning. Which of the following kinds of hemoglobin is likely to be the cause of his death? Carbhemoglobin Methemoglobin Carboxyhemoglobin Desoxyhemoglobin Oxyhemoglobin Test 154 A 29-year-old man with carbon monoxide poisoning is admitted to a hospital. He has signs of severe hypoxia. Which of the following substances is formed due to carbon monoxide poisoning? Methemoglobin Carboxyhemoglobin Carbhemoglobin Sulfhemoglobin Oxyhemoglobin Test 155 At altitude of 3500 m most of unacclimatized individuals develop dyspnea, dizziness and palpitation. Which of the following types of hypoxia underlines these symptoms? Circulatory Hypoxic Respiratory Hemic Tissue Test 156 Environmental pollution with nitrocompounds results from an accident on a chemical plant. People living in the affected region consult a doctor about weakness, headache, nausea and vomiting. Poisoning with nitrocompounds is suspected. Which of the following processes underlines hypoxia developed in the patients? Cytochromoxidase inactivation Dehydrogenase suppression Carboxyhemoglobin formation Decreased erythropoiesis Methemoglobin formation Test 157 Total respiratory insufficiency is revealed in a 35-year old woman suffering from bronchial asthma. Which of the following mechanisms is responsible for hypoxia in this patient? Decreased lung perfusion Decreased oxygen diffusion Decreased lung ventilation Suppression of the respiratory center Weakness of respiratory muscle Test 158 A 4-year-old boy with nitrite poisoning is admitted to a hospital. Which of the following mechanisms is responsible for hypoxia in this patient? Methemoglobin formation Inhibition of dehydrogenase Inhibition of cytochrome oxidase Carboxyhemoglobin formation Deficiency of riboflavin Поділіться з Вашими друзьями:
