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 D
Explanation
Choice A rationale
This is incorrect because respirations 16/min are within the normal range and do not indicate magnesium toxicity. The nurse should monitor the client's respiratory rate and report any signs of respiratory depression, such as less than 12/min.
Choice B rationale
This is incorrect because fetal heart rate 158/min is within the normal range and does not indicate fetal distress. The nurse should monitor the fetal heart rate and report any signs of bradycardia, tachycardia, or decreased variability.
Choice C rationale
This is incorrect because headache for 30 min is a common symptom of pre-eclampsia and does not indicate magnesium toxicity. The nurse should administer analgesics as prescribed and report any signs of increased intracranial pressure, such as blurred vision, confusion, or seizures.
Choice D rationale
This is correct because urinary output 40 mL in 2 hr is below the expected amount and indicates renal impairment. The nurse should report this finding to the provider and monitor the client's fluid intake and output, serum creatinine, and blood urea nitrogen levels. The nurse should also assess the client for signs of fluid overload, such as edema, crackles, or dyspnea.
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.
