A nurse is assisting in the care of a client who is in active labor. The nurse notes variable decelerations of the FHR. The nurse should identify which of the following as a cause of variable decelerations?
Fetal head compression
Polyhydramnios
Maternal fever
Umbilical cord compression
The Correct Answer is D
Choice A 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 B reason:
Polyhydramnios is incorrect, as this factor can cause variable or late decelerations in the fetal heart rate, depending on the underlying cause. Polyhydramnios refers to an excessive amount of amniotic fluid, which can result from fetal anomalies, maternal diabetes, multiple gestation, or other conditions. Polyhydramnios can cause umbilical cord prolapse, uterine overdistension, or placental abruption, leading to reduced blood flow and oxygen delivery to the fetus.
Choice C reason:
Maternal fever 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 fever can increase maternal and fetal metabolism and oxygen demand, leading to 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.

Correct Answer is A
Explanation
Choice A reason: This is the most appropriate response because it reassures the client that the amount of lochia she passed is normal and expected after lying down for a long time. Lochia is the vaginal discharge that occurs after childbirth, consisting of blood, mucus, and uterine tissue. It usually decreases in amount and changes in color over time, from red to pink to brown to yellow.
Choice B reason: This is an incorrect response because it implies that the client has a complication that requires further evaluation. Retained placental fragments can cause excessive bleeding, infection, and uterine atony. The nurse should not alarm the client with this possibility without evidence.
Choice C reason: This is an incorrect response because it contradicts the normal patern of lochia. The amount of lochia usually decreases during the postpartum period, not increases. If the client has an increase in lochia, it could indicate a problem such as infection, subinvolution, or hemorrhage.
Choice D reason: This is an incorrect response because it confuses the client with unrelated information. Urinary tract infections are not associated with increased lochia. They are caused by bacteria entering the urinary tract and can cause symptoms such as dysuria, frequency, urgency, and hematuria. The nurse should not suggest that the client has a urinary tract infection without evidence.
Correct Answer is A
Explanation
Choice A reason:
Panting can help prevent premature pushing and reduce the risk of cervical edema or laceration. The client should be instructed to take short, shallow breaths through her mouth during contractions until she reaches 10 cm of dilation.
Choice B reason:
Assessing the perineum for signs of crowning is not a priority at this stage, as the fetus is not yet at a low enough station to be visible. Crowning usually occurs when the fetus is at +4 or +5 station.
Choice C reason:
Assisting the client into a comfortable position is important, but it does not address the urge to push. The client should be encouraged to change positions frequently to promote fetal descent and comfort.
Choice D reason:
Helping the client to the bathroom to empty her bladder is not advisable, as it can increase the risk of cord prolapse or rupture of membranes. The client should have an indwelling catheter inserted if she is unable to void spontaneously.
