A nurse is caring for a client in the first stage of labor who is undergoing external fetal monitoring and receiving IV fluids. The nurse observes variable decelerations in the fetal heart rate on the monitor strip.
Which of the following is the correct interpretation of this finding
Variable decelerations are related to fetal head compression.
Variable decelerations are due to umbilical cord compression.
Variable decelerations are caused by uteroplacental insufficiency.
Variable decelerations are a result of the administration of narcotic analgesics.
The Correct Answer is B
The correct answer is Choice B.
Choice A rationale
Variable decelerations are not related to fetal head compression. Fetal head compression typically results in early decelerations, not variable ones.
Choice B rationale
Variable decelerations are indeed due to umbilical cord compression. They are quick decreases in fetal heart rate that vary with uterine contractions. This can be a sign that the baby’s blood flow is reduced if variable decelerations happen over and over.
Choice C rationale
Uteroplacental insufficiency typically results in late decelerations, not variable ones. Late decelerations are a sign of fetal hypoxia and are associated with uteroplacental insufficiency.
Choice D rationale
While certain medications can affect the fetal heart rate, variable decelerations are not typically a result of the administration of narcotic analgesics.

Correct Answer is A
Explanation
Choice A rationale
Preeclampsia is a condition that can occur during pregnancy, characterized by high blood pressure and signs of damage to another organ system, often the liver and kidneys. If a patient is experiencing preeclampsia, the nurse should initiate seizure precautions, as seizures can occur in severe cases. The nurse should also monitor the patient’s neurological status and liver function studies, as these can be affected by preeclampsia.
Choice B rationale
Hypertension, or high blood pressure, can occur during pregnancy, but the actions listed do not fully address the condition. While bed rest was once commonly recommended for high blood pressure during pregnancy, research has not shown it to be effective. Monitoring blood pressure and heart rate is important, but other interventions, such as medication, may also be necessary.
Choice C rationale
Gestational diabetes is a condition characterized by high blood sugar that develops during pregnancy. Insulin may be administered to help control blood glucose levels. The nurse should monitor blood glucose levels and fetal heart rate, as gestational diabetes can affect both the mother and the baby. However, the condition the patient is most likely experiencing, given the gestational age and symptoms, is preeclampsia.
Choice D rationale
Preterm labor refers to labor that begins before the 37th week of pregnancy. Tocolytics may be administered to slow or stop contractions. The nurse should monitor the contraction pattern and cervical dilation to assess for progression of labor. However, the condition the patient is most likely experiencing, given the gestational age and symptoms, is preeclampsia.
Correct Answer is D
Explanation
Choice A rationale
Abdominal pain accompanied by minimal red vaginal bleeding is not a typical symptom of placenta previa. In placenta previa, the placenta covers all or part of the cervix, which can cause severe bleeding. However, this bleeding is typically not associated with abdominal pain.
Choice B rationale
Intermittent abdominal pain following the passage of bloody mucus is not a common symptom of placenta previa. This symptom is more commonly associated with labor or other conditions, but not specifically with placenta previa.
Choice C rationale
Increasing abdominal pain with a nonrelaxed uterus is not a typical symptom of placenta previa. This could be a sign of other complications such as uterine rupture or placental abruption, which are serious conditions that require immediate medical attention.
Choice D rationale
Painless red vaginal bleeding is indeed a symptom of placenta previa. This bleeding is usually bright red and can occur intermittently or continuously. It is most common in the third trimester of pregnancy.
