Answer to Question 1

Ans:
B

Feedback:

Hypertension is a common cause of adaptive hypertrophy, in which cardiac muscle cells increase in size in response to the increased work of circulation over time. The other diagnoses are not associated with muscle hypertrophy.

Answer to Question 2

Ans:
C

Feedback:

Benign tumors are composed of well-differentiated, neoplastic cells that resemble the cells of the tissues of origin and are characterized by a slow, progressive rate of growth that may come to a standstill or regress. They tend to exist in a single mass. Malignant tumors tend to be poorly differentiated, grow rapidly, secrete hormones or cytokines, and have the potential to break loose.
