Answer to Question 2
Correct Answer: 4
Rationale 1: They are not cytotoxic.
Rationale 2: They block substances essential for hormone growth.
Rationale 3: They produce few debilitating adverse effects that other antineoplastics produce.
Rationale 4: This classification of medications can produce debilitating adverse effects when given at high doses for prolonged periods of time.
Global Rationale: In general, the hormones and hormone antagonists act by blocking the substances essential for tumor growth. Because these drugs are not cytotoxic, they produce few of the life-threatening toxic effects of antineoplastics from other classes. They can, however, produce significant adverse effects when given at high doses for prolonged periods.
