Answer to Question 1

ANS: A
Nitrosoureas are lipophilic and thus are able to cross the blood-brain barrier, making them more effective against solid tumors in the brain. They are alkylating agents with a broad spectrum of antineoplastic activity, but these are not the deciding factors in their use for brain tumors. Delayed bone marrow suppression is their major dose-limiting toxicity.

Answer to Question 2

ANS: A
Vincristine is a vesicant; extravasation of these agents can cause severe local injury that sometimes requires surgical debridement and skin grafting. The site should be changed, and the provider should be notified. Requesting a different drug is not indicated. Topical anesthetics will not prevent local tissue injury. Slowing the rate of infusion will not prevent local tissue injury.
