A nurse is assisting with the monitoring of a client who is in the first stage of labor, with an external fetal monitor in place and IV fluids infusing. Which of the following factors will cause variable decelerations in the fetal heart rate?
A. Fetal head compression.
Fetal head compression is unlikely to cause variable decelerations in the fetal heart rate. During contractions and labor, the fetal head may experience pressure, but this usually leads to early decelerations, not variable decelerations. Early decelerations are considered benign and are caused by the head's pressure stimulating the vagus nerve, resulting in a temporary decrease in heart rate.
B. Umbilical cord compression.
Umbilical cord compression is a known cause of variable decelerations in the fetal heart rate. When the umbilical cord is compressed, it can temporarily disrupt blood flow and oxygen supply to the fetus, leading to decelerations. Variable decelerations often appear as abrupt, sharp drops in the fetal heart rate and are typically characterized by their unpredictable nature.
C. Maternal opioid administration.
Maternal opioid administration is not a direct cause of variable decelerations in the fetal heart rate. While opioids can cross the placenta and may affect the fetus, they are more likely to cause other issues, such as respiratory depression in the newborn, rather than variable decelerations.
D. Uteroplacental insufficiency.
Uteroplacental insufficiency is not the primary factor causing variable decelerations. Uteroplacental insufficiency refers to an inadequate blood flow and oxygen delivery to the placenta, which can lead to late decelerations in the fetal heart rate, not variable decelerations.

Full Explanation
Choice A rationale:
Fetal head compression is unlikely to cause variable decelerations in the fetal heart rate. During contractions and labor, the fetal head may experience pressure, but this usually leads to early decelerations, not variable decelerations. Early decelerations are considered benign and are caused by the head's pressure stimulating the vagus nerve, resulting in a temporary decrease in heart rate.
Choice B rationale:
Umbilical cord compression is a known cause of variable decelerations in the fetal heart rate. When the umbilical cord is compressed, it can temporarily disrupt blood flow and oxygen supply to the fetus, leading to decelerations. Variable decelerations often appear as abrupt, sharp drops in the fetal heart rate and are typically characterized by their unpredictable
nature.
Choice C rationale:
Maternal opioid administration is not a direct cause of variable decelerations in the fetal heart rate. While opioids can cross the placenta and may affect the fetus, they are more likely to cause other issues, such as respiratory depression in the newborn, rather than variable decelerations.
Choice D rationale:
Uteroplacental insufficiency is not the primary factor causing variable decelerations. Uteroplacental insufficiency refers to an inadequate blood flow and oxygen delivery to the placenta, which can lead to late decelerations in the fetal heart rate, not variable decelerations.

A nurse is caring for a client who might have a hydatidiform mole. The nurse should monitor the client for which of the following findings?
A. Excessive uterine enlargement.
Excessive uterine enlargement. Rationale: The nurse should monitor the client for excessive uterine enlargement, as a hydatidiform mole is a rare condition in pregnancy where abnormal placental tissue forms instead of a fetus. This abnormal growth can lead to uterine enlargement beyond the expected size for gestational age.
B. Rapidly dropping human chorionic gonadotropin (hCG) levels.
Rapidly dropping human chorionic gonadotropin (hCG) levels. Rationale: The nurse should also monitor the client's hCG levels. In a normal pregnancy, hCG levels typically rise steadily during the early stages. However, in the case of a hydatidiform mole, hCG levels may either plateau or drop rapidly due to the abnormal placental growth.
C. Fetal heart rate irregularities.
Fetal heart rate irregularities. Rationale: Although a hydatidiform mole does not involve a viable fetus, the nurse should still assess for fetal heart rate irregularities. In some rare cases, the presence of abnormal placental tissue can cause confusion in the diagnosis, and there may be coexisting fetal development. Fetal heart rate irregularities may indicate potential complications.
D. Whitish vaginal discharge.
Whitish vaginal discharge. Rationale: Whitish vaginal discharge is not typically associated with a hydatidiform mole. Instead, this finding is more commonly seen in other vaginal infections or conditions unrelated to a molar pregnancy. The nurse should be cautious not to misinterpret this symptom as a definitive sign of a hydatidiform mole.

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?
A. This medication destroys Rh antibodies in a newborn who is Rh-positive.
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.
B. This medication destroys Rh antibodies in a woman who is Rh-negative.
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.
C. This medication prevents the formation of Rh antibodies by a woman who is Rh-negative.
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 of the newborn. Rho(D) immune globulin helps prevent this sensitization process.
D. This medication prevents the formation of RH antibodies in a newborn who is Rh-positive.
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.
