Answer to Question 1

ANS: B
Stomatitis, GI symptoms, and palmar-plantar erythrodysesthesias are dose-limiting side effects of fluorouracil, characterized by the symptoms described. When these occur, the provider should be notified. Continuous dosing is generally less toxic than bolus dosing. Reassurance without discontinuing the medication and contacting the provider is not correct. Dexamethasone is not given to counter these effects.

Answer to Question 2

ANS: A
Fluorouracil acts by depriving cancer cells of thymidylate, which is necessary to make DNA. It does not cause the accumulation of adenosine, disrupt the biosynthesis of nucleic acids, or inhibit DNA polymerase.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
