The nurse caring for the pregnant patient understands that the hormone essential for maintaining pregnancy is:
Estrogen
Oxytocin
Human chorionic gonadotropin (hCG)
Progesterone
The Correct Answer is D
Choice A rationale
Estrogen is not the hormone essential for maintaining pregnancy. Estrogen is a hormone that stimulates the growth and development of the female reproductive organs, the breasts, and the placenta. Estrogen also increases the blood flow and the uterine contractility during pregnancy. However, estrogen alone is not sufficient to sustain the pregnancy, as it needs to be balanced by progesterone.
Choice B rationale
Oxytocin is not the hormone essential for maintaining pregnancy. Oxytocin is a hormone that stimulates the contraction of the uterine and the mammary glands. Oxytocin plays a role in the initiation and the progression of labor, as well as in the milk ejection during breastfeeding. However, oxytocin is not involved in the maintenance of the pregnancy, as it can cause premature labor if released too early.
Choice C rationale
Human chorionic gonadotropin (hCG) is not the hormone essential for maintaining pregnancy. hCG is a hormone that is produced by the placenta and the embryo. hCG supports the corpus luteum, which is the structure that produces progesterone in the early pregnancy. hCG also prevents the immune system from rejecting the fetus, and stimulates the production of other hormones, such as estrogen and progesterone. However, hCG is not the main hormone that maintains the pregnancy, as its levels decline after the first trimester, when the placenta takes over the production of progesterone.
Choice D rationale
Progesterone is the hormone essential for maintaining pregnancy. Progesterone is a hormone that prepares the endometrium, which is the lining of the uterus, for the implantation of the fertilized egg. Progesterone also maintains the pregnancy by preventing the uterine contractions and the immune response against the fetus. Progesterone is produced by the corpus luteum in the early pregnancy, and by the placenta in the later pregnancy.

Correct Answer is C
Explanation
Choice A rationale
Assessing deep tendon reflexes every hour is an appropriate order for a client who has severe preeclampsia. This can help detect increased neuromuscular irritability, which is a sign of worsening preeclampsia or impending eclampsia. The nurse should report any hyperreflexia, clonus, or decreased sensation to the provider.
Choice B rationale
Continuous fetal monitoring is an appropriate order for a client who has severe preeclampsia. This can help assess the fetal well-being and detect any signs of fetal distress, such as bradycardia, tachycardia, or decreased variability. The nurse should report any abnormal fetal heart rate patterns to the provider.
Choice C rationale
Ambulating twice daily is not an appropriate order for a client who has severe preeclampsia. This may increase the risk of bleeding, seizures, or placental abruption. The client should be on bed rest or restricted activity to reduce the blood pressure and prevent complications.
Choice D rationale
Obtaining a daily weight is an appropriate order for a client who has severe preeclampsia. This can help monitor the fluid status and the severity of edema, which are common manifestations of preeclampsia. The nurse should report any excessive weight gain or loss to the provider.
Correct Answer is ["B","C","D"]
Explanation
Choice A rationale
Age of the client is not a significant risk factor for postpartum hemorrhage. While age can influence overall health and pregnancy complications, it is not directly linked to an increased risk of postpartum hemorrhage. Therefore, the age of the client, in this case, does not increase the risk for postpartum hemorrhage.
Choice B rationale
The use of forceps during delivery can increase the risk of postpartum hemorrhage. Forceps delivery is an assisted delivery method which can cause trauma to the birth canal, leading to increased bleeding after delivery. In this case, the client had a forceps-assisted delivery, which could increase her risk for postpartum hemorrhage.
Choice C rationale
A 4th degree laceration is a severe tear that occurs during delivery, extending to the anal sphincter and rectal mucosa. This type of laceration can lead to significant blood loss and increase the risk of postpartum hemorrhage. In this case, the client had a 4th degree laceration, which increases her risk for postpartum hemorrhage.
Choice D rationale
A long labor duration can increase the risk of postpartum hemorrhage. Prolonged labor can lead to uterine atony, a condition where the uterus does not contract properly after delivery, leading to increased bleeding. In this case, the client was in labor for 25 hours, which could increase her risk for postpartum hemorrhage.
