Answer to Question 1
B
Feedback:
A drug allergy is the formation of antibodies to a drug or drug protein; causes an immune response when the person is next exposed to that drug. A drug allergy does not occur at the first exposure to a drug. A second action of a specific drug is an adverse response that the drug causes in addition to the therapeutic effect. Serum sickness is one type of allergic reaction but does not define allergic reaction. An immediate systemic reaction to a drug, usually not on first exposure, is an anaphylactic reaction.
Answer to Question 2
C
Feedback:
Ascaris infection occurs where sanitation is poor. Eggs in the soil are ingested with vegetables or other improperly washed foods containing the worm. The patients may be unaware until a worm in their stool is seen or the patient becomes quite ill. Teaching patients the importance of washing fresh fruit and vegetables will help them reduce risk of infection. Washing hands, avoiding sharing hairbrushes or hats, and being aware in populated areas will reduce the risk of other infections but do not relate to ascaris.
