Correct Answer is ["A","B","C","D"]
Explanation
Choice A Reason: This is correct because cloudy malodorous fluid indicates that the amniotic fluid is contaminated with bacteria or other microorganisms that can cause infection in the woman or the fetus. Normally, amniotic fluid is clear and odorless.
Choice B Reason: This is correct because abdominal tenderness suggests that the woman has inflammation or irritation of the uterus or other pelvic organs due to infection. Abdominal tenderness can also be accompanied by cramping, pain, or fever.
Choice C Reason: This is correct because fetal bradycardia, which is a slow fetal heart rate below 110 beats per minute, indicates that the fetus is experiencing distress or hypoxia due to infection. Fetal bradycardia can be detected by electronic fetal monitoring or Doppler device.
Choice D Reason: This is correct because elevated maternal pulse rate, which is a heart rate above 100 beats per minute, indicates that the woman has an increased metabolic demand or systemic inflammation due to infection. Elevated maternal pulse rate can also be caused by dehydration, anxiety, or pain.
Choice E Reason: This is incorrect because decreased C-reactive protein levels do not indicate infection. C-reactive protein (CRP) is a protein that is produced by the liver in response to inflammation or infection. Increased CRP levels can be a sign of infection, but decreased CRP levels can be normal or indicate other conditions such as liver disease or malnutrition.
Correct Answer is C
Explanation
Choice A Reason: This is incorrect because cervical insufficiency is a condition where the cervix dilates prematurely and painlessly during pregnancy, leading to preterm delivery or second trimester abortion. It is not a common cause of first trimester abortion, which occurs before 12 weeks of gestation.
Choice B Reason: This is incorrect because uterine fibroids are benign tumors that grow in or on the uterus. They may cause heavy bleeding, pain, or infertility, but they are not a common cause of first trimester abortion. They may increase the risk of miscarriage in later stages of pregnancy.
Choice C Reason: This is correct because fetal genetic abnormalities are the most common cause of first trimester abortion, accounting for up to 70% of cases. Fetal genetic abnormalities are errors in the number or structure of chromosomes that occur during fertilization or cell division. They can cause developmental defects or fetal demise that result in spontaneous abortion.
Choice D Reason: This is incorrect because maternal disease is not a common cause of first trimester abortion. Maternal disease refers to any medical condition that affects the mother's health or pregnancy outcome, such as diabetes, hypertension, thyroid disorders, or infections. Maternal disease may increase the risk of miscarriage in later stages of pregnancy or cause other complications such as preterm labor or preeclampsia.
