Answer to Question 1

C
Prostate cancer, the second leading cause of cancer death in men, produces manifestations such as dysuria, increased urinary frequency, and a weak urinary stream; later symptoms are related to urethral obstruction or hematuria. Men over 65 are at greatest risk, but mortality rates are higher for those who are younger. A rectal examination during physician visits is one of the most useful screening method for prostate cancer.

Answer to Question 2

D
Tachycardia, a heart rate of 100 to 150 bpm, can have a variety of causes, including exercise, emotional stress, fever, medications, excessive caffeine intake, and tobacco use. This condition may disappear spontaneously or may be treated with prescribed medications.
