42. Several minutes after a dentist administered novocaine for local anaesthesia of a patient’s tooth, the following symptoms sharply developed in the patient: fatigue, skin itching. Objectively the following can be observed: skin hyperemia, tachycardia, BP dropped down to 70/40 mm Hg. What kind of allergic reaction is this pathology?
AAnaphylactic'>. Anaphylactic B. Cytotoxic C. Stimulating
D. Cell-mediated immune reaction E. Immune complex
43. A woman complaining of coryza, phonastenia, eyelids redness and lacrymation during spring period came to the doctor. What type of allergic reaction by Gell ano Coombs classification develops in this case?
A. Delayed type of hypersensitivity B. Immunocomplex
C. Stimulating D. Cytotoxic E. Anaphylactic
44. A patient who had been suffering for many years from bronchial asthma died from asphyxia. The histological examination of his lungs revealed the following: much mucus with eosinophiles contents in the lumen of bronchioles and small bronci, sclerosis of interalveolar septa, dilation of alveolar lumen. Which of the mechanisms of allergy development is it?
A. Immunocomplex B. Cytolysis, caused by lymphocytes
C. Cytotoxic D. Reagin E. Granulomatosis
45. A patient with paroxysmal attacks of asphyxia, which appear after inhalation of different aromatic substances has been made a diagnosis of bronchial asthma. Ig E rate is elevated. What type of reaction is it the most typical for?
A. Anaphylactic B. Delayed type of hypersensitivity
C. Autoimmune D. Cytotoxic E. Immunocomplex
46. A patient suffering from periodical attacks caused by inhalation of different flavoring substances was diagnosed with atopic bronchial asthma. IgE level was increased. This is typical for the following type of reactions:
A. Anaphylactic reactions B. Cytotoxic reactions
C. Immunocomplex reactions D. Delayed-type hypersensitivity
E. Autoimmune reactions
47. During anaesthetization of the oral cavity mucous tunic a patient developed anaphylactic shock (generalized vasodilatation, increase in vascular permeability along with escape of liquid to the tissues). What type of hypersensitivity has the patient developed?
A. I type (anaphylactic) B. II type (antibody-dependent)
C. III type (immune complex) D. IV type (cellular cytotoxicity)
E. V type (granulomatosis)
48. A teenger had his tooth extracted under novocain anaesthesia. 10 minutes later he presented with skin pallor, dyspnea, hypotension. When this reaction is developed and the allergen achieves tissue basophils, it reacts with:
A. IgE B. IgА C. IgD D. IgМ E. T-lymphocytes
49. A surgeon used novocaine as an anaesthetic during surgical manipulations. 10 minutes after it the patient became pale, he got dyspnea and hypotension. What type of allergic reaction is it?
A. Anaphylactic B. Cytotoxic C. Immune complex
D. Stimulating E. Cell-mediated
50. During anesthesia of the oral mucosa a 37-year-old patient has had anaphylactic reaction (widespread vasodilation, increased vascular permeability with liquid exiting the blood vessels and penetrating in the tissues). What type of hypersensitivity reaction occurred in the patient?
A. Type I (anaphylactic) B. Type II (antibody-dependent)
C. Type III (immune complex)
D. Type IV (cell cytotoxicity) E. Type V (granulomatosis)
51. After anaesthetic application during tooth extraction the patient developed marked soft tissue edema of the upper and lower jaw, skin rash on the face, reddening, and itching. What pathological process results in such reaction to the anaesthetic?
A. Toxic action of drug
B. Disturbed lymph drainage
