Answer to Question 1

ANS: C
Compensatory hyperplasia is an adaptive, not pathologic, mechanism that enables certain organs to regenerate. Metaplasia is the reversible replacement of one mature cell type by another, some-times less differentiated, cell type. Aplasia is not a compensatory mechanism.

Answer to Question 2

ANS: D
Because the changes are due to an imbalance, they would be considered pathologic hyperplasia, a term more descriptive than simple hyperplasia. The endometrial changes were not abnormal in size and shape; thus, it is not dysplasia regardless of cause.
