What procedure is commonly performed to establish the cause of abnormal uterine bleeding?

a. Pap smear
b. Hysteroscopy
c. Dilation and curettage (D&C)
d. Tubal ligation

ANS: C
A D&C is done for diagnostic and therapeutic purposes. It is performed for many reasons such as abnormal uterine bleeding, infertility studies, to relieve dysmenorrhea, remove polyps, remove residual tissue, arrest bleeding after incomplete abortion, and confirm preoperative diagnosis. The cervix is dilated and tissue is scraped with a curette; therefore, it is called a D&C.
