Answer to Question 1

ANS: A
The nurse should know about two different types of dosages for patients taking digoxin: the initial digitalizing dose and maintenance doses. More frequent and higher digitalizing doses are given when a patient begins taking digoxin so that a specific level of medication can be reached in the blood. Smaller maintenance doses are given once a day to maintain the blood level.

Answer to Question 2

ANS: A
The action of antineoplastic agents on normal cells causes many adverse reactions, which include alopecia and bone marrow depression.
