Mast cells in the tissue are comparable to which type of blood cells? platelets monocytes B lymphocytes basophilic granulocytes31. Which statement regarding anaphylaxis is correct? the immunoglobulin involved is IgA it is commonly caused by contact with metals, dyes or rubber it immediately leads to severe hypertension and hyperventilation it implies a sudden massive release of histamine in the general circulation32. What is meant by the term "etiology"? the symptoms and signs of a disease the identification of a specific disease the causative factors of a particular disease the chain of events leading to manifest disease33. Which of the following factors predispose to the development of pneumonia in elderly bed-ridden patients? retention of carbon dioxide deep and frequent breathing pooled secretions in the lungs frequent contact with family members, friends and neighbours34. Which condition is BOTH congenital AND genetic? cleft palate spina bifida phenylketonuria Huntington's chorea35.
