A nurse is assisting with the care of a client who is in labor. The client's labor is difficult and prolonged and she reports a severe backache. Which of the following factors is a contributing cause of difficult, prolonged labor?

Choice A reason: Check the client's temperature every 4 hr is incorrect, as this action is not frequent enough for a client who had an amniotomy. The nurse should check the client's temperature every 2 hr after an amniotomy, as there is an increased risk of infection due to the rupture of membranes. The nurse should also monitor for signs of chorioamnionitis, such as foul-smelling amniotic fluid, maternal tachycardia, or fetal tachycardia.

Choice B reason: Remind the client to bear down with each contraction is incorrect, as this action is not appropriate for a client who is in the active phase of the first stage of labor. The nurse should instruct the client to avoid bearing down or pushing until they are in the second stage of labor, when the cervix is fully dilated and effaced. Bearing down too early can cause cervical edema, lacerations, or exhaustion.

Choice C reason: Maintain the client in the lithotomy position is incorrect, as this action is not optimal for a client who is in the active phase of the first stage of labor. The lithotomy position is a supine position with the legs elevated and abducted, which can reduce blood flow to the uterus and placenta, increase perineal edema, and limit pelvic outlet diameter. The nurse should encourage the client to change positions frequently and use upright or lateral positions that can enhance uterine contractility, fetal descent, and maternal comfort.

Choice D reason: Encourage the client to empty the bladder every 2 hr is correct, as this action can promote labor progress and prevent bladder distension and infection. The nurse should assist the client to void every 2 hr after an amniotomy, as there may be decreased sensation of bladder fullness due to pressure from the fetal head. A full bladder can interfere with uterine contractions, fetal descent, and cervical dilation.

Choice A reason:

Maternal opioid administration is incorrect, as this factor can cause late decelerations in the fetal heart rate. Late decelerations are symmetrical decreases in the FHR that begin after the peak of the contraction and return to baseline after the contraction ends, which indicate uteroplacental insufficiency. Maternal opioid administration can reduce maternal blood pressure and placental perfusion, leading to fetal hypoxia.

Choice B reason:
Fetal head compression is incorrect, as this factor can cause early decelerations in the fetal heart rate. Early decelerations are symmetrical decreases in the FHR that mirror the contractions, which indicate fetal head compression and vagal stimulation. Fetal head compression occurs as the fetus descends into the birth canal and does not pose a threat to the fetal well-being.

Choice C reason:
Uteroplacental insufficiency is incorrect, as this factor can cause late decelerations in the fetal heart rate. Uteroplacental insufficiency refers to a reduced blood flow and oxygen delivery to the fetus through the placenta, which can result from maternal hypotension, uterine hyperstimulation, placental abruption, or other conditions. Uteroplacental insufficiency can cause fetal hypoxia and acidosis.

Choice D reason:
Umbilical cord compression is correct, as this factor can cause variable decelerations in the fetal heart rate. Variable decelerations are abrupt decreases in the FHR that vary in onset, duration, and depth, which indicate umbilical cord compression and reduced blood flow to the fetus. Umbilical cord compression can occur due to cord prolapse, nuchal cord, short cord, or other causes. The nurse should reposition the client, administer oxygen, and prepare for delivery if indicated.
