A nurse is reinforcing teaching with a client who is pregnant and has a prescription for Rho(D) immune globulin. Which of the following information should the nurse include?
This medication destroys Rh antibodies in a newborn who is Rh-positive.
This medication destroys Rh antibodies in a woman who is Rh-negative.
This medication prevents the formation of Rh antibodies by a woman who is Rh-negative.
This medication prevents the formation of RH antibodies in a newborn who is Rh-positive.
The Correct Answer is C
Choice A rationale:
This statement is incorrect because Rho(D) immune globulin does not destroy Rh antibodies in a newborn who is Rh-positive. Instead, it acts to prevent the development of Rh antibodies in the mother.
Choice B rationale:
This statement is also incorrect. Rho(D) immune globulin does not destroy Rh antibodies in a woman who is Rh-negative. It is given to Rh-negative women to prevent them from forming Rh antibodies in response to Rh-positive fetal blood during pregnancy.
Choice C rationale:
This is the correct choice. Rho(D) immune globulin is given to Rh-negative women to prevent the formation of Rh antibodies. If an Rh-negative woman is exposed to Rh-positive blood (usually during childbirth), her immune system may recognize the Rh antigen as foreign and start producing Rh antibodies. These antibodies could potentially cross the placenta during a subsequent pregnancy and attack the red blood cells of an Rh-positive fetus, causing hemolytic disease in the newborn. Rho(D) immune globulin helps prevent this sensitization process.
Choice D rationale:
This statement is incorrect. Rho(D) immune globulin does not prevent the formation of Rh antibodies in a newborn who is Rh-positive. Its main purpose is to protect Rh-negative women from forming antibodies that could harm future Rh-positive pregnancies.

Correct Answer is B
Explanation
Choice A rationale:
If the client is Rh positive and the newborn is Rh negative, there is no indication for administering Rho(D) immune globulin. Rho(D) immune globulin is only given when the Rh-negative mother gives birth to an Rh-positive baby.
Choice B rationale:
This is the correct choice for administering Rho(D) immune globulin. When the mother is Rh negative and the newborn is Rh positive, there is a risk of Rh incompatibility. If the fetal blood enters the mother's circulation during delivery, her immune system may produce antibodies against Rh-positive blood cells, which can be harmful to future Rh-positive pregnancies. To prevent this, Rho(D) immune globulin is administered to the Rh-negative mother shortly after delivery.
Choice C rationale:
If both the mother and the newborn are Rh-negative, there is no risk of Rh incompatibility. Rho(D) immune globulin is not required in this situation.
Choice D rationale:
If both the mother and the newborn are Rh-positive, there is no risk of Rh incompatibility. Rho(D) immune globulin is not indicated in this case.
Correct Answer is B
Explanation
Choice A rationale:
Severe nausea and vomiting are not indicative of an ectopic pregnancy. While nausea and vomiting are common symptoms in early pregnancy, they are not specific to ectopic pregnancies. These symptoms are more likely associated with typical pregnancy changes.
Choice B rationale:
Pelvic pain is a crucial finding that the nurse should expect in a possible ectopic pregnancy. As the pregnancy implants outside of the uterus, usually in the fallopian tube, it can cause sharp and severe pain in the pelvic region. This pain may be unilateral and can be accompanied by shoulder pain due to blood or fluid irritating the diaphragm.
Choice C rationale:
Uterine enlargement greater than expected for gestational age is not likely in an ectopic pregnancy. In fact, uterine enlargement may not be noticeable at all in an ectopic pregnancy since the embryo is not developing in the uterus.
Choice D rationale:
Copious vaginal bleeding is more commonly associated with miscarriages or other complications in intrauterine pregnancies. In an ectopic pregnancy, vaginal bleeding may occur, but it is typically lighter and often described as spotting.
