A nurse is observing the electronic fetal heart rate monitor tracing for a client who is at 40 weeks of gestation and is in labor. The nurse should suspect a problem with the umbilical cord when she observes which of the following patterns?
Accelerations.
Late decelerations.
Variable decelerations.
Early decelerations.
The Correct Answer is C
Choice A. Accelerations are normal responses that indicate the fetus is healthy and active. Accelerations occur when the fetal heart rate increases in response to stimuli. •
Choice B. Late decelerations are nonreassuring patterns that indicate fetal hypoxia due to placental insufficiency. Late decelerations occur when the placental blood flow decreases due to uterine contractions during labor, causing the fetal heart rate to decrease. •
Choice C. Variable decelerations are nonreassuring patterns that indicate fetal hypoxia due to umbilical cord compression. Variable decelerations occur when the umbilical cord is trapped by the cervical opening or the fetal body part, twisted, or knotted, causing the fetal oxygen supply to be impaired and the fetal heart rate to drop sharply. •
Choice D. Early decelerations are reassuring patterns that indicate a neural reflex due to fetal head compression. Early decelerations occur when the fetal head is compressed by uterine contractions during labor, causing the parasympathetic nervous system to be stimulated and the heart rate to decrease. The correct answer is C. Variable decelerations are the most common pattern that indicates a problem with the umbilical cord and requires urgent intervention.

Correct Answer is A
Explanation
Choice A reason:
This is the best response because it shows that the nurse is providing nonpharmacological pain relief measures and supporting the client's coping mechanisms. Breathing and imagery techniques can help the client relax and focus on something other than the pain. Moaning, screaming, and vocalizing are normal and acceptable ways of expressing pain during labor, and the nurse should not try to suppress them.
Choice B reason:
This is not the best response because it does not address the husband's concern or offer any intervention for the client's pain. Asking the client to rate her pain on a scale of 0 to 10 is a subjective assessment tool that may not reflect the true intensity of her pain. Furthermore, it may be difficult for the client to answer this question while she is in the second stage of labor.
Choice C reason:
This is not the best response because it may not be feasible or appropriate to administer more pain medication to the client in the second stage of labor. The obstetrician may not be available to evaluate the client's pain, and increasing the dose of pain medication may have adverse effects on the client and the fetus, such as respiratory depression, hypotension, and decreased uterine contractility.
Choice D reason:
This is not the best response because it does not acknowledge the husband's feelings or provide any comfort or education for him. Reassuring him that his wife will be fine may sound dismissive and insensitive, and offering to stay with her while he takes a walk may imply that he is not needed or wanted in the birthing room. The nurse should involve the husband in the care of his wife and explain to him what is happening and what to expect during labor.
Correct Answer is A
Explanation
Choice A reason:
The nurse's priority in this situation is the client's blood pressure of 80/56 mm Hg. Opioid epidural analgesia can cause a drop in blood pressure, known as hypotension. Hypotension can be a significant concern during labor, as it may reduce blood flow to the placenta and compromise the baby's well-being. Therefore, it is crucial for the nurse to address this finding promptly to prevent any adverse effects on both the mother and the baby. The nurse may need to administer intravenous fluids, adjust the dosage of the opioid medication, or take other appropriate actions to raise the blood pressure to a safer level.
Choice B reason:
While profuse itching (choice B) can be a common side effect of opioids, it is not the nurse's priority in this situation. Itching, also known as pruritus, can be managed with antihistamines or other supportive measures, but it is not an immediate threat to the client's well-being.
Choice C reason:
The client reporting weakness of the lower extremities (choice C) is an expected side effect of epidural analgesia. Epidurals can cause temporary paralysis or weakness in the lower body due to the local anesthetic's effects on the nerves. While it's essential to monitor and support the client during this time, it is not the priority over the potentially dangerous drop in blood pressure.
Choice D reason:
A temperature of 38.2°C (100.8 F) (choice D) may indicate a fever, but it is not the nurse's priority in this specific situation of opioid epidural analgesia during labor. Fever during labor could have various causes, and the nurse should investigate and manage it appropriately. However, addressing the client's blood pressure takes precedence, as hypotension can have immediate and significant consequences.
