One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because

A. Human placental lactogen (hPL) is a hormone produced by the placenta that helps regulate the metabolism of the mother and fetus, but it is not used as the basis for pregnancy tests. It plays a role in modulating the metabolic state of the mother during pregnancy to facilitate the energy supply of the fetus.

B. Estrogen (estriol) is another hormone produced by the placenta, which is important for maintaining pregnancy and preparing the body for childbirth. However, it is not the hormone detected by pregnancy tests. Estriol levels increase significantly during pregnancy but are not used as a marker for pregnancy tests.

C. Progesterone (progestin) is crucial for maintaining the uterine lining and supporting early pregnancy. While it is essential for a successful pregnancy, it is not the hormone that pregnancy tests detect. Progesterone helps prevent uterine contractions and supports the endometrium.

D. Human chorionic gonadotropin (hCG) is the hormone detected by pregnancy tests. It is produced by the placenta shortly after the embryo attaches to the uterine lining. The presence of hCG in the blood or urine is a reliable indicator of pregnancy, which is why it is the basis for pregnancy tests.

Choice A reason:

Assisting the client on a bedpan to urinate is important for assessing urinary output and preventing bladder distension. However, in this situation, the priority is to assess and manage postpartum hemorrhage, which is indicated by the excessive bleeding.

Choice B reason:

Increasing the client's fluid intake is generally a good measure for promoting hydration and maintaining blood volume. However, it is not the priority in this scenario of excessive postpartum bleeding.

Choice C reason:

Palpating the client's uterine fundus is the priority nursing intervention at this time. The excessive bleeding indicated by saturating two perineal pads in a 30-minute period suggests postpartum hemorrhage, which can result from uterine atony (failure of the uterus to contract adequately after childbirth). Palpating the fundus allows the nurse to assess if the uterus is firm or boggy, and if it is not contracting properly, immediate interventions can be initiated to control the bleeding.

Choice D reason:

Preparing to administer oxytocic medication (such as oxytocin) can help stimulate uterine contractions and prevent or manage postpartum hemorrhage. However, the priority is to first assess the uterine fundus and confirm the cause of the excessive bleeding before administering any medication.
