Answer to Question 1

Ans: B
Feedback:
Once an individual is allergic to one penicillin, he or she is usually allergic to all of the penicillins. Those allergic to penicillin also have a higher incidence of allergy to the cephalosporins. Allergy to drugs in the same or related groups is called cross-sensitivity. Hypersensitivity is an allergic reaction to one substance. Anaphylactoid reaction is an unusual or exaggerated allergic reaction. Anaphylaxis or anaphylactic shock is a severe form of hypersensitivity that occurs immediately and can be fatal.

Answer to Question 2

Ans: B
Feedback:
Cephalosporins are used to treat respiratory infections, otitis media, urinary tract infections, and bone and joint infections, and prophylactically to treat infections that may result from a sexual assault. Cephalosporins are not used to treat hemolysis or jaundice. Nausea and diarrhea are some of the adverse reactions that can occur when a patient is on cephalosporin therapy.
