Answer:
D&C
Step-by-step explanation:
D&C stands for dilation and curettage, which is a surgical procedure in which the cervix is expanded and the uterine lining is scraped to eliminated pregnant or unwanted tissue.
Pap could stand for pap smear in which a sample of vaginal or cervical tissue cells are examined on a slide in order to determine if a patient has certain infections. Though it is certainly an invasive procedure, it is not surgical in nature, in that no formal operation is required. Other possible expansions of pap as an abbreviation are also not surgical procedures, such as peak airway pressure, positive airway pressure, pulmonary arterial pressure, and primary atypical pneumonia.
HDN stands for hemolytic disease of a newborn a disease in which the neonate's blood hemolyzes due to their antigens being incompatible with the mother's immune system, causing these erythrocyte antigens to be attacked, broken down, and destroyed. This is a condition rather than a procedure.
GYN stands for gynecology or gynecologist, the study of conditions and physiology specific to the female genital tract and breasts and a medical specialist of the same, respectively. This is not a procedure either.
