It is determined that a client's blood Rh is negative and her partner's is positive. To help prevent Rh isoimmunization, the nurse would expect to administer Rho(D) immune globulin at which time?
24 hours before delivery and 24 hours after delivery
In the first trimester and within 2 hours of delivery
At 28 weeks gestation and again within 72 hours after delivery
At 32 weeks gestation and immediately before discharge
The Correct Answer is C
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.

Correct Answer is A
Explanation
Choice A Reason: This is correct because recurrent pelvic infections, such as pelvic inflammatory disease (PID), can cause scarring and inflammation of the fallopian tubes, which can impair the normal movement of the fertilized egg to the uterus. This can increase the risk of ectopic pregnancy, which is a life-threatening condition where the fertilized egg implants outside the uterine cavity, usually in the fallopian tube.
Choice B Reason: This is incorrect because ovarian cysts are fluid-filled sacs that develop in or on the ovaries. They are usually benign and do not affect fertility or pregnancy. However, some types of ovarian cysts, such as endometriomas or dermoid cysts, may require surgery to remove them, which can cause damage to the ovaries or fallopian tubes and increase the risk of ectopic pregnancy.
Choice C Reason: This is incorrect because use of oral contraceptives for 8 years is not a risk factor for ectopic pregnancy. In fact, oral contraceptives can reduce the risk of ectopic pregnancy by preventing ovulation and fertilization. However, if a woman becomes pregnant while taking oral contraceptives, she should stop taking them and consult her doctor, as they may have adverse effects on the developing fetus.
Choice D Reason: This is incorrect because heavy, irregular periods are not a risk factor for ectopic pregnancy. They may indicate other conditions such as hormonal imbalance, uterine fibroids, polycystic ovary syndrome (PCOS), or endometriosis, which can affect fertility or pregnancy, but not necessarily cause ectopic pregnancy.
Correct Answer is ["C","D","E"]
Explanation
Choice A: Absence of pain is not a sign of abruptio placenta. Abruptio placenta is a condition where the placenta separates from the uterine wall before delivery, causing bleeding and pain. The pain is usually severe and constant.
Choice B: Insidious onset is not a sign of abruptio placenta. Abruptio placenta is usually a sudden and acute event that occurs in the third trimester or during labor.
Choice C: Dark red vaginal bleeding is a sign of abruptio placenta. The bleeding is caused by the rupture of blood vessels between the placenta and the uterus. The blood may be dark red because it is old or clotted.
Choice D: Rigid uterus is a sign of abruptio placenta. The uterus becomes hard and tense as a result of the bleeding and contraction of the uterine muscles. This can impair the blood flow to the fetus and cause fetal distress.
Choice E: Absent fetal heart tones is a sign of abruptio placenta. The loss of blood and oxygen to the fetus can cause fetal death or stillbirth. Fetal heart tones can be detected by using a Doppler device or a fetoscope.
