Answer to Question 1

A, E
Feedback:
Malignant cells that remain in a dormant phase for long periods are difficult to destroy. These cells can emerge long after cancer treatment has finishedafter weeks, months, or yearsto begin their division and growth cycle all over again. For this reason, antineoplastic agents are often given in sequence over periods of time, in the hope that the drugs will affect the cancer cells as they emerge from dormancy or move into a new phase of the cell cycle. A combination of antineoplastic agents targeting different phases of the cell cycle is frequently most effective in treating many cancers. Combinations of drugs do not increase the length of treatment, increase the quantity of medication used, or decrease the adverse effects of the medications used.

Answer to Question 2

C
Feedback:
Bronchiectasis is a chronic disease that involves the bronchi and bronchioles. It is characterized by dilation of the bronchial tree, chronic infection, and inflammation of the bronchial passages. It is not caused by increased red blood cell concentration in the blood, leakage of fluid into the alveolar interstitial spaces, or the obstruction of the pulmonary vasculature by a clot.
