The General nosological concepts. Action of pathogenic environmental factors. At the end of the working day a worker of a hot work shop has been delivered to a hospital. The patient complains of a headache, dizziness, nausea, general weakness. Objectively: the patient is conscious, his skin is hyperemic, dry, hot to the touch. Heart rate is of 130/min. Respiration is rapid, superficial. What disorder of thermoregulation is most likely to have occurred in this patient?
Reduced heat transfer
Increased heat transfer and reduced heat production
Reduced heat production with no changes to the heat transfer
The processes of heat transfer in a naked person at room temperature have been studied. It was revealed that under these conditions the greatest amount of heat is transferred by:
Heat radiation
Heat conduction
Convection
Evaporation
-
The temperature of the ambient environment is 38oC and relative air humidity is 50%.What ways of heat emission provide maintaining a constant temperature of the human body?
Evaporation
Radiation
Heat conduction
Convection
Convection and conduction
The temperature in a production room is 36oC. Relative air humidity is 80%.
Under these conditions the human body transfers heat mainly through:
Sweat evaporation
Heat conduction
Radiation
Convection

Having helped to eliminate consequences of a failure at a nuclear power plant, a worker got an irradiation doze of 500 roentgen. He complains of headache, nausea, dizziness. What changes in leukocytes quantity can be expected 10 hours after irradiation?
Neutrophilic leukocytosis
Lymphocytosis
Leukopenia
Agranulocytosis
Leukemia
A disaster fighter at a nuclear power plant developed hemorrhagic syndrome on the background of acute radiation disease. What is the most important factor of syndrome pathogenesis?
Thrombocytopenia
