Answer to Question 1

B
Feedback:
Vaccines provide active immunity by stimulating production of antibodies to a specific protein, which may produce the signs and symptoms of a mild immune reaction, but it protects the person from the more devastating effects of disease. This protein may be a foreign substance, a bee sting, or a snake bite, but these answers are too narrow in focus.

Answer to Question 2

A, B, C, E
Feedback:
The actions of polymyxin B on cell membranes means it can be toxic to the human host, leading to nephrotoxicity, neurotoxicity (e.g., facial flushing, dizziness, ataxia, paresthesias, drowsiness), and drug-related fever and rash. This drug is reserved for infections that do not respond to less toxic drugs; the nurse needs to be alert for serious reactions and hold the drug until notifying the provider.
