The physician examines her and notes that the cervical os is open and blood is pooling in the vagina. Products of conception can be visualized in the os. The patient is prepared for a suction curettage. Which of the following is the most likely cause for the pregnancy loss?? A: Sexually transmitted disease STD, B: Rh immunization, C: Antiphospholipid syndrome, D: Chromosomal abnormalities, E: Trauma,  <response>: This is a question about the most likely cause of a first trimester pregnancy loss in a 23-year-old woman. Based on the description, this is likely a spontaneous abortion or miscarriage. The key findings are 10 weeks gestation based on LMP, sudden vaginal bleeding with clots and cramping, open cervical os with products of conception visible, and no history of trauma. The answer choices include sexually transmitted diseases, Rh immunization, antiphospholipid syndrome, chromosomal abnormalities, and trauma. STDs are less likely in the first trimester and there is no mention of STDs in the history. Rh immunization causes issues in subsequent pregnancies, not the first. Antiphospholipid syndrome may cause miscarriages but is less common than chromosomal issues. Chromosomal abnormalities are the most common cause of first trimester miscarriages. There is no history of trauma mentioned.Therefore, the most likely cause in this scenario is chromosomal abnormalities.D: Chromosomal abnormalities
