A nurse is conducting an in-service program for a group of nurses working at the women's health facility about the causes of spontaneous abortion. The nurse determines that the teaching was successful when the group identifies which condition as the most common cause of first trimester abortions?

Cervical insufficiency

Uterine fibroids

Fetal genetic abnormalities

Maternal disease

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is B

Explanation

Choice A Reason: This is incorrect because ambivalence is a mixed or contradictory feeling towards something or someone. It may occur in some women during pregnancy, especially if the pregnancy was unplanned or unwanted. However, it is not the most likely emotional response in the first trimester.

Choice B Reason: This is correct because emotional lability is a rapid and exaggerated change in mood or affect. It may occur in many women during pregnancy due to hormonal fluctuations, physical changes, and psychological stressors. Emotional lability may manifest as increased irritability, anxiety, sadness, or crying spells.

Choice C Reason: This is incorrect because introversion is a personality trait that indicates a preference for solitude and inward focus. It may be present in some women before or during pregnancy, but it is not an emotional response that is specific to the first trimester.

Choice D Reason: This is incorrect because acceptance is a positive attitude that indicates a willingness to embrace the reality of something or someone. It may develop in some women during pregnancy as they adjust to their new role and identity as mothers. However, it is not the most likely emotional response in the first trimester.

A. 24 hours before delivery and 24 hours after delivery B. In the first trimester and within 2 hours of delivery C. At 28 weeks gestation and again within 72 hours after delivery D. At 32 weeks gestation and immediately before discharge

Correct Answer is C

Explanation

Choice A Reason: This is incorrect because administering Rho(D) immune globulin 24 hours before delivery is too early and may not provide adequate protection for the fetus. Administering it 24 hours after delivery is too late and may not prevent the mother from developing antibodies against the fetal Rh-positive blood cells.

Choice B Reason: This is incorrect because administering Rho(D) immune globulin in the first trimester is unnecessary and may not be effective, as the risk of Rh isoimmunization is very low before 28 weeks of gestation. Administering it within 2 hours of delivery is appropriate, but not sufficient, as it should be repeated within 72 hours after delivery.

Choice C Reason: This is correct because administering Rho(D) immune globulin at 28 weeks gestation and again within 72 hours after delivery is the recommended schedule for preventing Rh isoimmunization in Rh-negative pregnant women who have Rh-positive partners. This regimen can prevent up to 99% of cases of Rh isoimmunization by blocking the maternal immune response to the fetal Rh-positive blood cells.

Choice D Reason: This is incorrect because administering Rho(D) immune globulin at 32 weeks gestation is too late and may not prevent Rh isoimmunization if there has been any fetal-maternal hemorrhage before that time. Administering it immediately before discharge is also too late and may not prevent the mother from developing antibodies against the fetal Rh-positive blood cells.
