One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because
It produces a prolapsed cord.
It increases maternal renal blood flow.
It decreases maternal blood pressure.
There is a reduction of placental blood flow.
The Correct Answer is D
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.

Correct Answer is C
Explanation
Choice A reason:
Charting the normal axillary temperature is not the priority in this situation. The infant's temperature is subnormal, indicating hypothermia, which requires immediate intervention.
Choice B reason:
Rechecking the infant's temperature rectally may provide a more accurate reading, but it is not the priority action at this moment. The infant's low temperature indicates the need for immediate warming to prevent further complications.
Choice C reason:
Placing the infant in a radiant warmer is the priority nursing action. The axillary temperature of 35.9°C (96.6°F) is below the normal range for a newborn, which is around 36.5-37.5°C (97.7-99.5°F). Hypothermia in newborns can be dangerous and lead to respiratory distress, metabolic problems, and other complications. A radiant warmer provides a controlled heat source to warm the infant and stabilize their body temperature.
Choice D reason:
Having the mother breastfeed the infant may help provide warmth and comfort, but it is not the priority action. The immediate concern is to raise the infant's body temperature to a safe range using a radiant warmer.
Correct Answer is C
Explanation
Choice A: the interval between contractions
Encouraging a laboring woman to push during the interval between contractions is not appropriate. During this time, the uterus is not contracting, and pushing would be ineffective and exhausting for the woman. The intervals are meant for rest and recovery to prepare for the next contraction.
Choice B: whenever she feels the need
While it is important to listen to the laboring woman’s instincts, pushing should be coordinated with contractions for maximum effectiveness. Pushing whenever she feels the need might not align with the contractions, leading to ineffective efforts and increased fatigue.
Choice C: second-stage of labor
The second stage of labor is the most appropriate time for the nurse to encourage a laboring woman to push. This stage begins when the cervix is fully dilated to 10 centimeters and ends with the birth of the baby. During this stage, contractions are strong and frequent, providing the necessary force to help push the baby through the birth canal.
Choice D: first-stage of labor
The first stage of labor involves the dilation and effacement of the cervix and is not the appropriate time for pushing. Pushing during this stage can cause unnecessary strain and may lead to complications. The focus during the first stage should be on managing contractions and conserving energy for the second stage.
