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 B
Explanation
Choice A reason: Hematuria is blood in the urine. It is not a symptom of endometritis, which is an inflammation or infection of the uterine lining. Hematuria can have many other causes, such as urinary tract infections, kidney stones, bladder cancer, or trauma.
Choice B reason: Pelvic pain is one of the most common symptoms of endometritis. It can be caused by the inflammation or infection of the uterine lining, which can also spread to other pelvic organs. Pelvic pain can be dull, sharp, cramping, or constant, and it may worsen with movement or intercourse¹³.
Choice C reason: Pink lochia is normal vaginal discharge after childbirth. It consists of blood, mucus, and tissue from the uterus. It usually lasts for a few weeks and gradually changes color from red to pink to brown to white. Pink lochia is not a sign of endometritis, unless it is foul-smelling, heavy, or persists beyond six weeks.
Choice D reason: Bradycardia is a slow heart rate, usually below 60 beats per minute. It is not a symptom of endometritis, which can cause fever and tachycardia (fast heart rate). Bradycardia can have many other causes, such as heart disease, medication side effects, hypothyroidism, or electrolyte imbalance.
Correct Answer is A
Explanation
Expressions of excitement are typical during the dependent, taking-in phase, which lasts for the first 24 to 48 hr after delivery. The client may relive and review her labor and delivery experience, and may need reassurance and validation from others.
Choice B reason:
Lack of appetite is not an expected finding during the dependent, taking-in phase, as the client may have increased hunger and thirst after delivery. The nurse should encourage adequate nutrition and hydration to promote healing and lactation.
Choice C reason:
Eagerness to learn newborn care skills is more characteristic of the dependent-independent, taking-hold phase, which begins around the third day postpartum. During this phase, the client becomes more confident and interested in caring for herself and her newborn.
ChoiceD reason:
Focus on the family unit and its members is more characteristic of the interdependent, letting-go phase, which occurs after the first week postpartum. During this phase, the client redefines her role within the family and society, and integrates the newborn into her life.
