Answer to Question 1

Ans:
C

Feedback:

Abnormalities detected during a DRE provide a rationale for further investigation by biopsy. PSA is used to screen for prostate cancer; however, it is also positive in BPH. The anatomic location of the prostate at the bladder neck contributes to the pathophysiology and symptomatology of BPH. A BPH is not a definitive sign of prostate cancer. DRE is recommended annually for all men over age 50.

Answer to Question 2

Ans:
C

Feedback:

Ligaments exist where a bone connects to its articulating mate, as in the case of the synovial joint between the tibia and femur that constitutes the knee. Ligaments do not connect the ribs to the sternum, and the radius and biceps are connected by a tendon. The interfaces between the skull plates are considered joints, but these are not ligaments.
