A maternal indication for the use of vacuum extraction is

Choice A reason:

A prolapsed umbilical cord occurs when the cord slips ahead of the presenting fetal part, potentially leading to cord compression and compromised fetal oxygenation. However, hypertonic contractions do not directly cause a prolapsed cord. Instead, factors such as premature rupture of membranes, abnormal fetal positioning, or excessive amniotic fluid (polyhydramnios) are more likely contributors to cord prolapse. Hypertonic contractions primarily affect uteroplacental circulation rather than fetal positioning.

Choice B reason:

One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it produces a prolapsed cord. This is incorrect because a prolapsed cord is not caused by hypertonic contractions, but by other factors such as a low-lying placenta, a premature rupture of membranes, a small or preterm fetus, or an abnormal presentation. A prolapsed cord occurs when the umbilical cord slips through the cervix and into the vagina before or during delivery. This can compress the cord and cut off the blood supply to the fetus, resulting in fetal bradycardia and possible death.

Choice C reason:

One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it increases maternal renal blood flow. This is incorrect because hypertonic contractions do not affect maternal renal blood flow directly. Maternal renal blood flow is influenced by factors such as maternal blood pressure, hydration, cardiac output, and renal function. Hypertonic contractions may cause maternal dehydration, which can reduce renal blood flow, but this is not a direct effect of oxytocin stimulation.

Choice D reason:

Hypertonic contractions reduce placental blood flow by limiting the relaxation phase between contractions. Normally, uterine contractions intermittently compress the spiral arteries supplying the placenta, but prolonged or excessively frequent contractions prevent adequate placental perfusion. This can lead to fetal hypoxia, acidosis, and distress, making it the most detrimental effect of oxytocin-induced hypertonic contractions.

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.
