Answer to Question 1

Ans:
C

Feedback:

The osteoblasts, or bone-building cells, are responsible for the formation of the bone matrix and would participate in the healing process. Osteocytes are mature bone cells, while osteoclasts reabsorb bone cells. An osteoma is a bone tumor.

Answer to Question 2

Ans:
B

Feedback:

Previous tubal ligation is an identified risk factor for ectopic pregnancy. Young age, use of injectable contraception, and low BMI are not specifically associated with ectopic pregnancy.
